Cap Rate vs. DSCR: Two Essential Metrics Explained

Cap rate and DSCR are the two most-referenced metrics in rental property investing, but they measure different things and serve different purposes. Understanding both — and how they interact — makes you a better investor.

Cap Rate: The Property's Unlevered Return

Cap Rate = Net Operating Income (NOI) ÷ Property Value

Cap rate measures what the property earns as a percentage of its value, ignoring financing entirely. It answers: "If I bought this property with cash, what would my return be?"

Example:

• Property value: $300,000
• Annual NOI: $21,000 (rent minus operating expenses, before mortgage)
• Cap rate: $21,000 ÷ $300,000 = 7.0%

What Cap Rate Tells You

• How the property performs independent of financing
• Whether the property is priced fairly relative to its income
• How it compares to other investment options (stocks, bonds, etc.)

What Cap Rate Doesn't Tell You

• Whether the deal works with a mortgage
• How much cash flow you'll actually receive
• Whether your DSCR loan will be approved

DSCR: The Property's Ability to Cover Debt

DSCR = Gross Rental Income ÷ PITIA (Mortgage Payment)

DSCR measures whether the rental income covers the mortgage. It answers: "Can this property pay for itself?"

Example:

• Monthly rent: $1,900
• Monthly PITIA: $1,600
• DSCR: $1,900 ÷ $1,600 = 1.19

What DSCR Tells You

• Whether the property qualifies for a DSCR loan
• How much cushion exists between rent and mortgage
• How vulnerable you are to rent drops or expense increases

What DSCR Doesn't Tell You

• Your actual cash flow after all expenses
• The property's value relative to its income
• How the property compares to one purchased with cash

How They Work Together

Key insight: A high cap rate property can have a low DSCR if interest rates are high. A low cap rate property can have a high DSCR if the down payment is large enough. Financing decisions (down payment, rate, term) connect the two metrics.

The Relationship Formula

You can roughly estimate DSCR from cap rate using this relationship:

DSCR ≈ Cap Rate ÷ Mortgage Constant × (1 - LTV)

This is approximate, but it illustrates why:

• Higher cap rates lead to higher DSCRs (more income relative to value)
• Higher interest rates lead to lower DSCRs (higher debt costs)
• Lower LTV leads to higher DSCRs (less debt to cover)

Which Metric Matters More?

For loan qualification: DSCR is all that matters. Your lender doesn't calculate cap rate.

For investment analysis: Both matter. Cap rate tells you if the property is fairly priced. DSCR tells you if the financing works.

For comparing markets: Cap rate is better (financing-neutral comparison). A 7% cap rate in Memphis vs. a 4% cap rate in San Francisco tells you about the markets, not about specific loan structures.

For comparing specific deals: DSCR is more practical. It accounts for your actual financing terms and tells you whether the deal generates positive cash flow.

Current Market Context (2026)

With DSCR loan rates around 7-8%, the relationship between cap rate and DSCR has shifted:

• Properties need a cap rate of ~6%+ to achieve a 1.20 DSCR at 75% LTV
• In 2020-2021 (3-4% rates), a 4% cap rate property could easily hit 1.20 DSCR
• Today's rate environment favors cash flow markets with higher cap rates

This is why Midwest and Southeast markets (6-9% cap rates) are dominating DSCR investing right now, while coastal markets (3-5% cap rates) struggle to produce viable DSCR ratios.

Practical Application

When evaluating a DSCR deal:

1. Calculate the cap rate — is the property fairly priced at 6%+ cap?
2. Calculate the DSCR — does it meet your lender's minimum (1.0-1.25)?
3. Compare to alternatives — could your capital earn more elsewhere?
4. Project forward — how will rent growth and potential rate changes affect both metrics over 5-10 years?
