Blanket Mortgages Explained: How Multi-Property Investors Use One Loan to [Finance Multiple Properties](/blog/how-to-finance-multiple-properties)

If you're a real estate investor managing multiple properties, you've probably felt the pain of juggling separate mortgages — different lenders, different payment dates, different terms, different escrow accounts. A blanket mortgage consolidates all of that into a single loan secured by multiple properties.

But blanket loans are more nuanced than "one mortgage for everything." The release clause structure, cross-collateralization risk, and qualifying requirements matter enormously. This guide covers all of it.

What Is a Blanket Mortgage?

A blanket mortgage is a single loan that uses two or more properties as collateral. Instead of taking out individual loans on each property, the borrower obtains one loan that covers the entire portfolio — or a subset of it.

Simple example: An investor owns four rental duplexes worth $300,000 each ($1.2M total). Instead of four separate $225,000 mortgages, they take one $900,000 blanket loan secured by all four properties.

Who Uses Blanket Mortgages?

• Residential real estate investors with 5+ rental properties
• House flippers acquiring multiple properties simultaneously
• Real estate developers building multiple lots or units
• Commercial property investors with mixed portfolios
• Land developers subdividing parcels for resale

Blanket loans are not typically used for a primary residence. They're investor and commercial tools.

How Blanket Mortgages Work: Structure and Mechanics

The Basic Structure

How Payments Work

You make one monthly payment that covers all properties in the blanket. The lender holds one deed of trust (or mortgage) recorded against each property, but the loan is administered as a single account.

Example payment calculation:

• Blanket loan: $900,000 at 7.50%, 30-year amortization
• Monthly P&I: $6,293
• Compared to four separate loans at 7.50%: 4 × $1,573 = $6,293

The total payment is the same, but you deal with one lender, one statement, one [escrow analysis](/blog/mortgage-escrow-explained), and one wire transfer.

Release Clauses: The Most Important Feature

A release clause (also called a partial release provision) allows you to sell or refinance individual properties out of the blanket loan without triggering a full loan payoff.

This is arguably the most critical feature of any blanket mortgage. Without a release clause, selling one property requires paying off the entire blanket loan — which defeats much of the purpose.

How Release Clauses Work

The release clause specifies:

1. Release price — the dollar amount you must pay to release a specific property from the blanket
2. Release formula — how the release price is calculated
3. Remaining coverage test — minimum LTV or debt coverage the remaining portfolio must maintain

Common Release Price Formulas

Formula 1: Pro-Rata Based on Appraised Value

Release price = (Property's appraised value ÷ Total portfolio appraised value) × Outstanding loan balance

Example: Property worth $300K in a $1.2M portfolio with $900K outstanding balance. Release price = ($300K ÷ $1.2M) × $900K = $225,000

Formula 2: Fixed Percentage of Allocated Loan Amount

Release price = 110–125% of the property's allocated loan amount

Example: $225,000 allocated to a property. Release price at 115% = $258,750

The lender requires more than the proportional share because releasing a property removes collateral while potentially leaving the remaining loan under-secured.

Formula 3: Fixed Dollar Amount

Some blanket loans set a specific release price per property at origination. This provides certainty but can become unfavorable if property values change significantly.

Why the Release Premium Matters

That 110–125% release price isn't just a lender markup — it serves a structural purpose. Consider:

• Total portfolio value: $1,200,000
• Total loan: $900,000 (75% LTV)
• You sell Property A (worth $300,000) and pay the pro-rata release: $225,000
• Remaining portfolio value: $900,000
• Remaining loan balance: $675,000
• New LTV: 75% — still fine

Now with a 115% release price:

• You pay $258,750 to release Property A
• Remaining loan balance: $641,250
• New LTV: 71.3% — even better for the lender

The premium ensures the remaining portfolio stays within acceptable LTV parameters even if the remaining properties' values decline.

Negotiating Release Clauses

1. Get the release clause in writing before closing. If a lender says "we'll work it out later," find a different lender.
2. Push for release prices at 100–110% of proportional allocation. Anything above 120% is aggressive.
3. Ensure the clause allows partial releases without lender "sole discretion" approval. You want a mechanical formula, not a subjective decision.
4. Clarify the remaining coverage test. What LTV must the remaining portfolio maintain? What happens if one property drops in value?
5. Include a timeline. The lender should process release requests within 30–60 days, not "when they get to it."

Cross-Collateralization: The Double-Edged Sword

Cross-collateralization means that each property in the blanket secures the entire loan, not just its proportional share. This is the default structure of a blanket mortgage, and it has significant implications.

What It Means Practically

• If one property in your portfolio suffers a casualty loss, the lender can demand additional collateral or acceleration of the loan
• If you default on the blanket loan, the lender can foreclose on any or all properties — not just the one causing the problem
• A title issue or lien on one property can complicate the entire blanket loan

Managing Cross-Collateralization Risk

1. Maintain adequate insurance on every property — including replacement cost coverage, not just ACV (actual cash value)
2. Keep reserves — most blanket lenders require 6–12 months of reserves, but having 12–18 months provides a buffer
3. Hold properties in a single-purpose entity — an LLC that owns only the blanket-encumbered properties, separate from your other assets
4. Monitor property conditions — deferred maintenance or code violations on one property can trigger lender concerns about the entire portfolio

Where to Get a Blanket Mortgage

1. Community Banks

The most common source. Community banks and regional banks with commercial lending departments frequently offer blanket mortgages. They understand local real estate markets and can evaluate portfolios property by property.

• Look for banks with commercial real estate (CRE) departments
• Ask about their blanket loan or portfolio loan program
• Typical minimums: $500K–$1M loan amount, 3+ properties

2. Portfolio Lenders Specializing in Investors

Several national lenders focus specifically on investor blanket loans:

• [Lima One Capital](/blog/lima-one-capital-dscr-review) — Blanket loans for rental portfolios, 5–30 year terms
• Kiavi (formerly LendingHome) — Bridge and rental portfolio financing
• CoreVest Finance (Redwood Trust) — [Portfolio loans](/blog/portfolio-lending-guide) for 5+ rental properties, up to $50M
• Visio Lending — DSCR-based blanket loans for rental investors
• Aloha Capital — Blanket bridge loans for fix-and-flip portfolios

3. CMBS and Conduit Lenders

For larger portfolios ($5M+), [commercial mortgage](/blog/commercial-mortgage-guide)-backed securities (CMBS) lenders offer competitive blanket financing. These loans are securitized and sold to bond investors, so they come with:

• Very strict terms and documentation
• Lockout periods (no prepayment for 2–5 years)
• Defeasance requirements (complex prepayment mechanism)
• Less flexibility on modifications

4. Private/Hard Money Lenders

For short-term needs (bridge loans, acquisition financing, renovation portfolios), private lenders offer blanket loans with:

• Faster closing (1–3 weeks)
• Less documentation
• Higher rates (10–14%)
• Shorter terms (12–36 months)
• Points (2–4 [origination points](/blog/mortgage-points-explained))

Qualifying for a Blanket Mortgage

Income and Cash Flow Requirements

Most blanket lenders evaluate the portfolio's aggregate debt-service coverage ratio (DSCR):

DSCR = Total [Net Operating Income](/blog/net-operating-income-guide) ÷ Total Debt Service

Example:

• 5 properties generating combined gross rent of $12,000/month
• Operating expenses (taxes, insurance, maintenance, vacancy reserve): $4,000/month
• Net Operating Income (NOI): $8,000/month
• Blanket loan payment (P&I + escrow): $6,500/month
• DSCR: $8,000 ÷ $6,500 = 1.23x

Most lenders require 1.20x–1.30x DSCR for blanket loans. Some will go as low as 1.10x with strong compensating factors.

Credit and Experience Requirements

Property Requirements

• Occupancy: Most lenders require 85–90% occupancy across the portfolio at the time of funding
• Condition: Properties must be habitable and rent-ready (no major deferred maintenance)
• Geographic concentration: Some lenders limit how many properties can be in a single ZIP code or MSA
• Property types: Most blanket lenders accept single-family, 2–4 unit, and small multifamily (5–20 units); some include mixed-use and light commercial

Blanket Mortgage Strategies for Investors

Strategy 1: Portfolio Consolidation

If you've accumulated 5–10 properties with individual loans over the years, a blanket refinance can:

• Simplify management (one payment, one lender)
• Potentially lower your blended interest rate
• Free up conventional lending capacity (your individual loans no longer count toward Fannie Mae's 10-property limit)
• Cash out equity across the portfolio for additional acquisitions

Strategy 2: Acquisition Line

Some blanket lenders offer revolving blanket facilities that work like a line of credit. You draw against the line to acquire new properties, which are added to the blanket collateral pool. This dramatically speeds up acquisitions — you can close in days rather than weeks.

Strategy 3: Bridge-to-Blanket

Acquire properties individually using bridge loans or cash, rehab them, stabilize with tenants, then refinance the entire portfolio into a long-term blanket mortgage. This approach lets you:

• Move quickly on acquisitions (cash or bridge)
• Add value through renovation
• Lock in a lower rate once properties are stabilized

Strategy 4: Sell and Reinvest

Use the release clause to sell underperforming properties, use the release payment to pay down the blanket, and then acquire replacement properties. This ongoing portfolio optimization is one of the biggest advantages of a well-structured blanket loan.

Common Blanket Mortgage Mistakes

1. Ignoring the release clause (or not having one). Without a release clause, you can't sell individual properties without paying off the entire loan. Always negotiate a release clause before closing.

2. Overestimating portfolio cash flow. When projecting DSCR, use conservative vacancy rates (8–10%) and realistic maintenance reserves (5–10% of gross rent). Lenders will verify, and over-optimism leads to denials.

3. Cross-collateralizing everything you own. Don't put every property you own into a single blanket. Keep some properties free and clear or on separate loans as a financial safety net.

4. Choosing the wrong term structure. A 5-year term with 30-year amortization means a balloon payment in 5 years. If you can't refinance at that point (due to rate changes, property value declines, or personal financial changes), you're in trouble. Longer terms (7–10 years) cost slightly more but provide much more safety.

5. Forgetting about due-on-sale clauses. If you're transferring properties into an LLC and then using them as blanket collateral, verify that the existing mortgages don't have due-on-sale clauses that could be triggered. (The Garn-St. Germain Act protects transfers to certain trusts, but LLC transfers may not be protected.)

The Bottom Line

Blanket mortgages are one of the most powerful tools available to multi-property real estate investors. They simplify portfolio management, [reduce closing costs](/blog/mortgage-closing-costs-breakdown), bypass conventional financing limits, and create strategic flexibility through release clauses.

But they also introduce cross-collateralization risk, require careful release clause negotiation, and come with higher rates than individual conventional loans.

The right approach:

1. Start with 5+ stabilized properties — most blanket lenders have minimums
2. Work with a lender experienced in blanket loans — not every bank knows how to structure these
3. Negotiate the release clause aggressively — this is your most important term
4. Keep reserves high — cross-collateralization means one problem can affect your entire portfolio
5. Plan your exit — know what happens at term maturity, whether that's refinancing, selling, or extending
