Real Estate Investing Glossary: 100+ Terms Defined in Plain English

Real estate has its own language. Investors, agents, lenders, and attorneys throw around acronyms and jargon that can make a simple conversation feel like a foreign language — ARV, DSCR, NOI, LTV, BRRRR, DST, QI, NNN...

This glossary cuts through the noise. Every term is defined in plain English with practical context: not just what it means, but why it matters to you as an investor.

Terms are organized alphabetically. Use Ctrl+F (or Cmd+F on Mac) to search for specific terms.

A

1031 Exchange A tax-deferral strategy that lets you sell an investment property and reinvest the proceeds into a "like-kind" property without paying capital gains tax at the time of sale. You must identify the replacement property within 45 days and close within 180 days. Named after Section 1031 of the Internal Revenue Code. Why it matters: On a $200K gain, a 1031 exchange can defer $40,000–$60,000+ in federal and state taxes.

Absorption Rate The rate at which available homes or rental units are sold or leased in a specific market over a given period. Calculated as: units sold or leased ÷ total available units. An absorption rate above 20% per month indicates a seller's/landlord's market. Why it matters: Helps you gauge whether a market is oversupplied or undersupplied before you buy.

Accredited Investor An individual with a net worth exceeding $1 million (excluding primary residence) or annual income exceeding $200,000 ($300,000 jointly) for the past two years. Required for most real estate syndication investments. Why it matters: Determines which passive investment opportunities you can legally access.

Adjustable-Rate Mortgage (ARM) A mortgage with an interest rate that changes periodically based on a benchmark index. Common structures: 5/1 ARM (fixed for 5 years, adjusts annually after) or 7/1 ARM. Why it matters: ARMs offer lower initial rates but carry risk if rates rise. Common in commercial and portfolio lending for investors.

After-Repair Value (ARV) The estimated market value of a property after renovations are complete. Used in fix-and-flip and BRRRR analysis. Calculated by analyzing comparable sales of renovated properties in the same area. Why it matters: Your entire rehab budget and profit depend on an accurate ARV. Overestimate ARV and you lose money.

Amortization The process of paying off a loan through regular payments over time, where each payment covers both principal and interest. A 30-year amortization means the loan is fully paid off in 360 monthly payments. Why it matters: Longer amortization = lower monthly payments = better cash flow. Shorter amortization = faster equity building.

Appraisal A professional opinion of a property's market value, conducted by a licensed appraiser. Required by most lenders before funding a loan. Why it matters: If the appraisal comes in below your purchase price, the lender will only loan against the appraised value — you'll need to cover the gap or renegotiate.

Appreciation The increase in a property's value over time. Can be "market appreciation" (the rising tide that lifts all boats) or "forced appreciation" (value increases from improvements or increased income). Why it matters: Appreciation is one of the four wealth generators in real estate, alongside cash flow, loan paydown, and tax benefits.

Assessed Value The value assigned to a property by the local tax assessor for the purpose of calculating property taxes. Often differs significantly from market value. Why it matters: If your assessed value is too high, you're overpaying property taxes. You can appeal the assessment in most jurisdictions.

B

Balloon Payment A large, lump-sum payment due at the end of a loan term when the loan has not been fully amortized. Common in seller financing and some commercial loans. Example: a 5-year loan with 30-year amortization — after 5 years, the entire remaining balance is due. Why it matters: You need an exit plan (refinance or sale) before the balloon date.

Basis Your total investment in a property for tax purposes. Includes purchase price plus closing costs plus capital improvements, minus accumulated depreciation. Why it matters: Your basis determines your taxable gain when you sell. Lower basis = higher tax bill.

Bird Dog An informal term for someone who finds potential investment deals and passes them along to an investor for a fee (typically $500–$5,000). Not a licensed position. Why it matters: Bird dogs can expand your deal flow without you doing the legwork. Verify your state's legality around bird dog fees.

Bonus Depreciation A tax provision allowing investors to deduct a large percentage of the cost of qualifying assets (short-lived property components identified through cost segregation) in the first year. Under current law, bonus depreciation is being phased down: 40% in 2025, 20% in 2026, 0% in 2027 (unless Congress extends it). Why it matters: Combined with a cost segregation study, bonus depreciation can generate massive first-year paper losses.

BRRRR Buy, Rehab, Rent, Refinance, Repeat — a strategy for recycling investment capital. You buy a distressed property below market value, renovate it, rent it out, refinance based on the new (higher) appraised value, and pull your capital back out to reinvest. Why it matters: Allows you to scale a portfolio without needing new capital for each acquisition.

Bridge Loan A short-term loan (6–18 months) used to "bridge" the gap between purchasing a property and securing permanent financing. Higher interest rates (8–14%) but fast closing. Why it matters: Essential for BRRRR and value-add strategies where the property doesn't qualify for conventional financing in its current condition.

Buy Box Your predefined criteria for what makes an acceptable investment: property type, location, price range, minimum returns, condition, etc. Why it matters: A clear buy box prevents emotional purchases and lets your team (agent, wholesalers) filter deals for you.

C

Cap Rate (Capitalization Rate) Net Operating Income (NOI) ÷ Property Value. Represents the annual return on a property as if you paid all cash. A property with $30,000 NOI and a $400,000 value has a 7.5% cap rate. Why it matters: The universal metric for comparing investment properties. Higher cap rate = higher return (but usually higher risk). Typical ranges: 4–6% (Class A, low risk), 6–8% (Class B), 8–12% (Class C/D, higher risk).

Capital Expenditure (CapEx) Major improvements that extend a property's life or add value: new roof, HVAC replacement, foundation repair, full kitchen remodel. CapEx is capitalized and depreciated over time (not deducted as a current expense). Why it matters: Budget 5–10% of gross rent for CapEx reserves. Failing to reserve for CapEx is the #1 reason new investors get blindsided by large bills.

Capital Gains Tax Tax on the profit from selling an investment property. Short-term (held < 1 year): taxed at ordinary income rates (up to 37%). Long-term (held > 1 year): taxed at 0%, 15%, or 20% depending on income. Why it matters: On a $200K gain, the difference between short-term and long-term rates can be $20,000–$40,000+ in taxes.

Cash Flow The money left over after all expenses are paid. Gross rent minus mortgage payment, taxes, insurance, property management, maintenance, vacancy allowance, and CapEx reserves. Why it matters: Cash flow is your monthly paycheck from a rental property. Positive cash flow = money in your pocket. Negative = you're subsidizing the investment.

Cash-on-Cash Return (CoC) Annual pre-tax cash flow ÷ total cash invested. If you invest $50,000 and receive $5,000/year in cash flow, your CoC is 10%. Why it matters: Measures how hard your actual dollars are working. Different from cap rate because it accounts for leverage (your mortgage).

Class A / B / C / D (Property Classification) Informal grading system for property quality and location:

• Class A: Newest, best locations, highest rents, lowest returns, lowest risk
• Class B: Good quality, stable neighborhoods, moderate returns
• Class C: Older properties, working-class neighborhoods, higher returns, more management-intensive
• Class D: Distressed properties, high-crime areas, highest potential returns, highest risk and management burden

Why it matters: Your target class should match your risk tolerance, management capacity, and return goals.

Closing Costs Fees and expenses incurred when completing a real estate transaction: title insurance, appraisal, loan origination, attorney fees, recording fees, transfer taxes. Typically 2–5% of purchase price for buyers. Why it matters: Closing costs are part of your all-in investment and affect your cash-on-cash return.

Comparable Sales (Comps) Recently sold properties similar to your target property in location, size, condition, and features. Used to estimate market value (for purchases) or after-repair value (for rehabs). Why it matters: Bad comps = bad valuation = bad deal. Use 3–6 comps from the past 6 months within a 0.5–1 mile radius.

Conventional Loan A mortgage that conforms to Fannie Mae or Freddie Mac guidelines. Typically requires 620+ credit score, 20–25% down for investment properties, and income verification. Limited to 10 financed properties per borrower. Why it matters: Best rates and terms available for properties 1–10, but the 10-property limit means you'll eventually need alternative financing.

Cost Segregation An engineering-based study that reclassifies components of a building into shorter depreciation categories (5, 7, or 15 years instead of 27.5 or 39 years). Accelerates depreciation deductions. Why it matters: Can generate $50,000–$200,000+ in first-year deductions on a $500K property.

D

Debt Service The total amount of principal and interest payments on a loan over a given period. Monthly debt service on a $200,000 loan at 7% over 30 years is approximately $1,331. Why it matters: Debt service is your largest monthly expense and the primary determinant of cash flow.

Debt Service Coverage Ratio (DSCR) Net Operating Income ÷ Annual Debt Service. A DSCR of 1.25 means the property generates 25% more income than needed to cover its loan payments. Most lenders require a minimum DSCR of 1.2–1.25. Why it matters: DSCR loans are qualified based on the property's income, not yours — critical for scaling beyond conventional loan limits.

Deed The legal document that transfers ownership of real property from one party to another. Types include warranty deed (seller guarantees clear title), quitclaim deed (no guarantees), and special warranty deed (guarantees only during seller's ownership). Why it matters: Always insist on a warranty deed with title insurance for maximum protection.

Depreciation A tax deduction that allows you to deduct the cost of the building (not land) over its useful life: 27.5 years for residential rental property, 39 years for commercial. Why it matters: Depreciation is a "paper loss" — it reduces your taxable income without costing you actual money. On a $300K building, that's ~$10,909/year in deductions.

Due Diligence The investigation period after going under contract where you inspect the property, verify financials, review title, and confirm the deal meets your criteria. Typically 10–21 days. Why it matters: Your due diligence contingency lets you back out without penalty if you discover issues.

Duplex / Triplex / Fourplex (2–4 Units) Small multifamily properties with 2, 3, or 4 units respectively. Important distinction: properties with 1–4 units qualify for residential financing (Fannie Mae/Freddie Mac). 5+ units are commercial. Why it matters: 2–4 unit properties offer the best of both worlds: multifamily cash flow with residential loan terms.

E

Earnest Money Deposit (EMD) A good-faith deposit submitted with an offer to purchase, typically 1–3% of the purchase price. Held in escrow and applied to closing costs or down payment. Why it matters: If you back out without a valid contingency, you may forfeit your EMD. If the deal closes, it reduces your cash to close.

Effective Gross Income (EGI) Gross Potential Income minus vacancy and credit loss, plus other income (laundry, parking, fees). Represents the realistic income a property will generate. Why it matters: Use EGI, not gross potential income, when calculating returns. Assuming 0% vacancy is a rookie mistake.

Equity The difference between a property's market value and the outstanding mortgage balance. If your property is worth $400,000 and you owe $250,000, your equity is $150,000. Why it matters: Equity is your net wealth in real estate. You can access it through cash-out refinancing, HELOCs, or selling.

Escrow

1. A neutral third party that holds funds and documents during a real estate transaction. 2) An account held by your lender to pay property taxes and insurance on your behalf (funded through your monthly payment). Why it matters: Escrow protects both parties in a transaction and ensures taxes/insurance are paid on time.

Estoppel Certificate A document signed by a tenant confirming the terms of their lease: rent amount, deposit, lease dates, and any side agreements. Required during the sale of a tenant-occupied property. Why it matters: Protects the buyer from disputes about lease terms after closing.

Eviction The legal process of removing a tenant from a property for lease violations (typically non-payment of rent). Timeline varies dramatically by state: 2–3 weeks in Texas, 3–6 months in California, 6–12+ months in New York City. Why it matters: Understanding your market's eviction timeline is critical for cash flow projections and risk assessment.

F

Fair Housing Act Federal law prohibiting discrimination in housing based on race, color, national origin, religion, sex, familial status, and disability. Applies to all landlords. Why it matters: Violations carry penalties of $16,000–$100,000+. Use consistent screening criteria for all applicants.

Fair Market Rent (FMR) HUD-determined rent levels for each metropolitan area, used for Section 8 voucher payment standards. Published annually. Why it matters: FMR gives you a government-backed rent benchmark and is relevant if you accept Section 8 tenants.

Fix and Flip Buying a distressed property, renovating it, and selling it for profit. Profits are taxed as ordinary income (not capital gains) if held less than one year. Why it matters: Higher potential returns per deal than buy-and-hold, but also higher risk, higher tax rate, and no passive income.

Forced Appreciation Increasing a property's value through improvements (rehab, adding units) or increasing income (raising rents, adding revenue streams). Distinct from market appreciation, which is passive. Why it matters: In commercial/multifamily, forced appreciation is directly tied to NOI — increase NOI by $10K at a 7% cap rate and you add $142,857 in value.

G

General Contractor (GC) A licensed professional who oversees and manages a construction or renovation project, typically hiring and coordinating subcontractors. Why it matters: A reliable GC is one of the most valuable members of your investor team. Always verify license, insurance, and references.

Gross Rent Multiplier (GRM) Property Price ÷ Annual Gross Rent. A quick-and-dirty valuation metric. A property priced at $200,000 with $24,000 in annual rent has a GRM of 8.3. Lower GRM = better value relative to income. Why it matters: Useful for rapid screening but doesn't account for expenses. Always follow up with full cash flow analysis.

Gross Potential Income (GPI) The total income a property would generate if fully occupied at market rents with no collection losses. Why it matters: GPI is the theoretical ceiling. Actual income will always be lower due to vacancy, concessions, and non-payment.

H

Hard Money Loan A short-term, asset-based loan from a private lender (not a bank). Higher rates (10–14%), higher fees (2–4 origination points), and shorter terms (6–18 months). Underwritten based on the property's value, not the borrower's income. Why it matters: Enables quick acquisitions and rehab financing when conventional loans don't apply. Essential for fix-and-flip and BRRRR.

HELOC (Home Equity Line of Credit) A revolving credit line secured by the equity in a property (typically your primary residence). Draw funds as needed, pay interest only on what you borrow. Why it matters: HELOCs are a popular source of down payment funds for investment properties. Interest may be tax-deductible if funds are used for investment purposes.

House Hacking Buying a 2–4 unit property, living in one unit, and renting the others to cover (or exceed) your mortgage payment. Qualifies for owner-occupied financing (3.5% down FHA, 5% down conventional). Why it matters: The lowest barrier to entry in real estate investing. Reduces or eliminates your housing cost while building equity and landlord experience.

HUD-1 / Closing Disclosure The standardized form detailing all costs and credits in a real estate transaction. The HUD-1 was replaced by the Closing Disclosure for most residential transactions in 2015. Why it matters: Review this document line by line before closing. Errors are common and can cost you thousands.

I

Internal Rate of Return (IRR) The annualized rate of return that accounts for the time value of money across all cash flows (investment, rental income, sale proceeds). More comprehensive than cash-on-cash because it factors in the entire hold period. Why it matters: IRR is the gold standard for comparing investments with different hold periods and cash flow patterns. Target IRR for most rental investors: 12–20%.

Interest-Only Loan A loan where you pay only interest (no principal) for a set period, after which payments include principal. Common in commercial lending and some bridge loans. Why it matters: Maximizes cash flow in the short term but builds no equity through payments. Useful during stabilization or rehab periods.

J

Joint Venture (JV) A partnership between two or more parties for a specific investment deal. Unlike a syndication, JVs typically involve fewer partners (2–5) with more active involvement from each. Why it matters: JVs let you combine capital, expertise, and deal flow without the legal complexity of a syndication.

K

Key Money A payment (often illegal or regulated) that a tenant or buyer makes above the normal rent or price for the right to occupy a property. More common in commercial leases. Why it matters: Understand your state's regulations around key money to avoid legal issues.

L

Landlord-Tenant Law State and local laws governing the rights and responsibilities of landlords and tenants. Covers security deposits, eviction procedures, habitability standards, lease requirements, and more. Varies dramatically by state. Why it matters: Knowing your state's landlord-tenant law is non-negotiable. Violating it — even accidentally — can result in penalties, lost eviction cases, or lawsuits.

Lease Option (Rent-to-Own) A lease agreement that gives the tenant the option (not obligation) to purchase the property at a predetermined price during or at the end of the lease term. Why it matters: Can command above-market rent and a non-refundable option deposit. Useful for selling properties in slow markets.

Lien A legal claim against a property as security for a debt. Common types: mortgage lien, tax lien, mechanic's lien (from unpaid contractors), judgment lien. Why it matters: Liens must be resolved before clean title can be transferred. Always get title insurance.

Like-Kind Property In 1031 exchanges, any real property held for investment or business use qualifies as "like-kind" to any other real property. A single-family rental can be exchanged for a commercial building, vacant land, or apartment complex. Why it matters: The definition is broader than most investors realize — almost any real property qualifies.

Loan-to-Value Ratio (LTV) Loan amount ÷ property value. An $160,000 loan on a $200,000 property = 80% LTV. Lower LTV = more equity = lower risk for the lender = better terms. Why it matters: Most investment property loans require 75–80% LTV maximum (meaning 20–25% down payment).

M

Market Value The price a property would sell for on the open market between a willing buyer and willing seller, both with reasonable knowledge and no pressure to act. Why it matters: Market value is the basis for lending decisions, insurance, and exit planning.

Material Participation IRS standard requiring active, regular, and continuous involvement in a trade or business. For real estate investors, material participation in each rental activity allows losses to offset other income (when combined with REPS). Why it matters: Without material participation, rental losses are "passive" and can only offset passive income.

MLS (Multiple Listing Service) A database used by real estate agents to list properties for sale. Publicly accessible through Zillow, Redfin, and Realtor.com (with some delay). Why it matters: The MLS is where most retail buyers find properties, but off-market deals (not on MLS) often offer better investor pricing.

N

Net Operating Income (NOI) Effective Gross Income minus all operating expenses (excluding debt service and capital expenditures). The fundamental measure of a property's operating performance. Why it matters: NOI is used to calculate cap rate, property value (in commercial), and DSCR. It's the single most important number in multifamily/commercial investing.

NNN (Triple Net) Lease A lease structure where the tenant pays rent plus all three "nets": property taxes, insurance, and maintenance. Common in commercial retail and single-tenant industrial. Why it matters: NNN properties offer truly passive income — the landlord has minimal expenses beyond debt service.

Non-Recourse Loan A loan where the lender can only seize the collateral (the property) if the borrower defaults — they cannot pursue the borrower's personal assets. Common in commercial lending over $1M and agency (Fannie/Freddie) multifamily loans. Why it matters: Protects your personal assets. Recourse loans (most residential investment loans) allow the lender to pursue you personally.

O

Off-Market Deal A property for sale that is not publicly listed on the MLS. Found through direct outreach, wholesalers, networking, driving for dollars, or direct mail. Why it matters: Off-market deals typically have less competition and better pricing — 10–30% below market is common for motivated sellers.

Operating Expenses The costs of running a rental property: property taxes, insurance, property management, maintenance, utilities (if owner-paid), landscaping, accounting, etc. Does NOT include mortgage payments or capital expenditures. Why it matters: Operating expenses typically run 35–50% of gross rent for residential properties. The "50% rule" (expenses = 50% of rent) is a useful quick estimate.

Owner Financing (Seller Financing) When the property seller acts as the lender, allowing the buyer to make payments directly to them instead of obtaining a bank loan. Terms are negotiable. Why it matters: Enables deals that don't qualify for traditional financing. Often offers more flexible terms: lower down payment, no bank qualification, creative structuring.

P

Passive Income Income from rental activities in which you don't materially participate. Under IRS rules, rental income is generally classified as passive regardless of your involvement (with exceptions for REPS). Why it matters: Passive losses can only offset passive income — unless you qualify for REPS or the $25,000 active participation allowance (phased out above $100K AGI).

Points (Loan Origination) Upfront fees charged by a lender, expressed as a percentage of the loan amount. 1 point = 1% of the loan. On a $200,000 loan, 2 points = $4,000 due at closing. Why it matters: Points are a cost of borrowing that affect your total investment and returns. Hard money lenders typically charge 2–4 points.

Portfolio Lender A bank or credit union that keeps loans on its own books (doesn't sell them to Fannie Mae/Freddie Mac). Can offer more flexible terms and underwriting criteria. Why it matters: Portfolio lenders can finance properties beyond the conventional 10-property limit and often have more flexible income documentation requirements.

Price-to-Rent Ratio Property price ÷ annual rent. A $200,000 property renting for $2,000/month ($24,000/year) has a price-to-rent ratio of 8.3. Lower ratios indicate better cash flow markets. Why it matters: Quick market-level metric. Ratios below 12 generally indicate good cash flow markets; above 20 indicates appreciation-focused markets where cash flow is difficult.

Private Money Loans from individuals (not institutions) for real estate investment. Typically friends, family, or high-net-worth individuals seeking better returns than traditional investments. Why it matters: Private money is relationship-based and can offer the most creative and favorable terms of any financing source.

Pro Forma Projected financial performance of a property, typically showing expected income, expenses, and returns over a future period. Why it matters: Always verify pro forma assumptions against actual market data. Sellers and brokers often present optimistic pro formas.

Property Management Company A firm that handles day-to-day operations of rental properties: tenant screening, rent collection, maintenance coordination, evictions, and accounting. Fees: 8–12% of gross rent for single-family, 5–8% for large multifamily. Why it matters: A great PM enables scaling; a bad PM destroys returns. Vet thoroughly.

Q

Qualified Intermediary (QI) A neutral third party required in a 1031 exchange to hold the sale proceeds between the sale of the relinquished property and purchase of the replacement property. Why it matters: If you touch the proceeds at any point, the exchange is disqualified. The QI must be engaged before the sale closes.

R

Real Estate Professional Status (REPS) An IRS designation for individuals who spend 750+ hours per year in real property trades or businesses AND more than half of their total working hours in real estate. Why it matters: REPS allows unlimited deduction of rental losses against ordinary income (W-2, business income) — potentially saving $20,000–$100,000+ per year in taxes.

Rent Roll A document listing all units in a property with their current tenants, lease terms, rent amounts, and payment status. Why it matters: The rent roll is the first document to review when evaluating an income property. Verify it against actual bank deposits and lease agreements.

Rent-to-Price Ratio (1% Rule) Monthly rent ÷ purchase price. A property that rents for $1,500/month and costs $150,000 meets the "1% rule" (1.0%). Why it matters: Properties meeting the 1% rule generally cash flow positive with conventional financing. It's a quick screening tool, not a substitute for full analysis. In many markets, 0.7–0.8% is more realistic.

Replacement Cost The cost to rebuild a property from scratch at current material and labor prices. Why it matters: Buying below replacement cost provides a margin of safety — the property is worth more to rebuild than you paid.

Reserve Fund Cash set aside for unexpected expenses and vacancies. Standard recommendation: 3–6 months of total expenses per property. Why it matters: Properties without adequate reserves eventually become emergencies.

S

Section 8 (Housing Choice Voucher) A federal program where HUD subsidizes rent payments for qualifying low-income tenants. The tenant pays a portion; the government pays the rest directly to the landlord. Why it matters: Guaranteed government rent payments, lower vacancy, but more inspections and bureaucracy. Can be highly profitable in the right markets.

Seller Concession The seller agrees to pay a portion of the buyer's closing costs or other expenses as part of the deal. Limits vary by loan type (typically 2–6% of purchase price). Why it matters: Reduces your cash to close, effectively lowering your initial investment.

Short Sale A sale where the proceeds are less than the outstanding mortgage balance, requiring lender approval. Why it matters: Short sales can offer below-market pricing but involve long timelines (60–120+ days) and uncertain lender approval.

Subject-To (Sub-To) Acquiring a property "subject to" the existing mortgage — the buyer takes ownership and makes payments on the seller's existing loan without formally assuming it. Why it matters: Enables acquisition without qualifying for a new loan and may allow keeping the seller's lower interest rate. Carries risk of the lender calling the loan due (due-on-sale clause).

Syndication A structure where a sponsor (general partner) pools capital from multiple passive investors (limited partners) to acquire and manage a property. Governed by securities law. Why it matters: Allows passive investing in large deals ($5M–$100M+) with minimums typically $50,000–$100,000. Returns target 15–20% IRR.

T

Tax Lien A lien placed on a property by a government entity for unpaid property taxes. In some states, investors can purchase tax liens and earn interest when the owner pays the delinquent taxes. Why it matters: Tax lien investing offers high fixed returns (8–36% depending on state) secured by real property.

Tenant Screening The process of evaluating prospective tenants: credit check, criminal background check, income verification (3x rent minimum), rental history, and eviction records. Why it matters: Proper screening is your best defense against problem tenants. Use consistent criteria for every applicant to comply with Fair Housing.

Title Insurance Insurance that protects against losses from defects in title (ownership) not found during the title search. Lender's title insurance is required; owner's title insurance is optional but strongly recommended. Why it matters: Protects your investment from claims like undisclosed liens, forged documents, or boundary disputes.

Turnkey Property A fully renovated, tenant-occupied, property-managed rental sold to investors as a "ready to go" investment. Why it matters: Lower barrier to entry for out-of-state investors, but typically priced at retail with lower returns than value-add strategies.

U

Umbrella Insurance A supplemental liability policy that provides coverage beyond the limits of your landlord/dwelling policies. Typically $1–2M in additional coverage for $200–$750/year. Why it matters: If a tenant or visitor is injured on your property and sues for more than your dwelling policy limit, the umbrella covers the excess.

Under Contract The period between an accepted offer and closing. The property is reserved for the buyer, subject to contingencies (inspection, financing, appraisal). Why it matters: Your due diligence happens during this period.

Underwriting The lender's process of evaluating a loan application: reviewing the borrower's creditworthiness, income, assets, and the property's value and income potential. Why it matters: Understanding what underwriters look for helps you structure deals that get approved.

V

Vacancy Rate The percentage of units (or time) that a property is unoccupied. A property vacant 1 month out of 12 has an 8.3% vacancy rate. Why it matters: Budget 5–10% vacancy allowance in your analysis. Actual vacancy depends on market, property quality, management, and pricing.

Value-Add An investment strategy focused on acquiring underperforming properties and increasing their value through renovations, better management, or rent increases. Why it matters: Value-add is how investors create returns above market average. Forced appreciation through operational improvements is the core mechanism.

W

Wholesaling A strategy where an investor puts a property under contract and then assigns (sells) that contract to another investor for a fee, without ever taking ownership. Why it matters: Requires no capital or credit but generates smaller per-deal profits ($5,000–$20,000 typical). Wholesale deals are a key source of below-market properties for buy-and-hold investors.

Y

Yield The annual income return on an investment, expressed as a percentage. Can refer to rental yield (annual rent ÷ property value) or total yield (including appreciation and tax benefits). Why it matters: Yield puts returns in context — a $500/month cash flow is meaningless without knowing the investment amount.

Z

Zoning Local government regulations that dictate how a property can be used: residential, commercial, industrial, mixed-use, agricultural, etc. Zoning determines what you can build, how many units you can have, and what businesses can operate. Why it matters: Always verify zoning before purchase. Zoning changes (rezoning) can dramatically increase or decrease property value. A single-family-zoned lot that gets rezoned for multifamily can double in value overnight.
