Debt Yield vs Cap Rate: Lender vs Investor Metric

Two deals, same market, same property type, the same $1,000,000 of NOI — and a 5% cap rate on both. One gets financed without issue. The other hits a debt yield floor and comes back $2 million short.

Cap rate and debt yield use the same NOI numerator but answer completely different questions. Confusing them — or assuming one passes when the other does — is one of the most common missteps in deal sizing. The thing that connects them is leverage.

Cap Rate = NOI / Property Value
Debt Yield = NOI / Loan Amount

Cap rate prices the asset

Cap rate tells you the unlevered return implied by the property's income and value. If a property has $800,000 of NOI and sells for $10,000,000, the cap rate is 8.00%.

Investors use cap rates to compare pricing, market risk, asset quality, and expected return before financing is applied. The Urban Land Institute and major commercial real estate research firms track cap rate movements by market and asset class precisely because they reveal how the market is pricing risk.

Debt yield sizes the loan

Debt yield tells the lender how much income supports the loan balance. If the same $800,000 NOI property carries an $8,000,000 loan, the debt yield is 10.00%.

Lenders use debt yield to judge whether the loan is reasonable even if the appraisal, rate, or amortization changes. The Commercial Real Estate Finance Council notes that debt yield is specifically valued because it is immune to the variables that make other metrics manipulable.

Why the ratios can diverge

A property can have a strong cap rate and a weak debt yield if the borrower asks for too much debt. It can also have a low cap rate and an acceptable debt yield if the loan is conservative.

For example, a $1,000,000 NOI property valued at $20,000,000 has a 5.00% cap rate. If the loan is $10,000,000, debt yield is 10.00%. The asset may look richly priced by investor standards, but the loan can still be well protected — because the lender advanced only 50% of value.

The bridge between them is leverage

Cap rate and debt yield connect through LTV. If loan amount equals property value, cap rate and debt yield are identical. In real lending, the loan is always below value, so debt yield is always higher than cap rate.

The approximate relationship at different LTV levels:

At 75% LTV, a 5% cap rate implies only a 6.7% debt yield — which fails most CMBS programs and many conventional lenders. At 60% LTV, the same asset implies 8.3% — which clears most conventional floors. The cap rate did not change. Only the leverage did.

This is why low-cap-rate markets are disproportionately affected by debt yield constraints. Lenders in those markets cannot simply accept the asset's strong valuation as a substitute for income cushion.

How to use both in underwriting

Use cap rate to understand valuation. Use debt yield to understand credit protection. Then check DSCR and LTV to see whether payment coverage or collateral leverage creates a tighter limit.

The cap rate calculator shows cap rate, implied values, LTV, and debt yield when you include a loan amount. To size the loan itself, use the debt yield calculator or the full CRE loan sizing calculator.

Cap rate tells you how the market prices the income. Debt yield tells you how much of that income protects the lender.

Frequently asked questions

If cap rate is higher than the lender's debt yield floor, does the loan automatically pass? Not necessarily. Cap rate uses property value in the denominator. Debt yield uses loan amount. Because the loan is always less than the full value, debt yield will always be higher than cap rate at any reasonable LTV — but both must clear their respective benchmarks independently. A high cap rate is a positive signal on asset pricing, not a substitute for the debt yield test.

Why do some markets make debt yield constraints harder to clear? Low-cap-rate markets — coastal multifamily, gateway office, high-barrier industrial — often create tension because asset prices are high relative to NOI. When a borrower prices a deal at a 4% cap rate and requests 70% LTV, the resulting debt yield may be only 6.5%–7%, which is well below most lenders' floors. The same property in a higher-cap-rate market might clear easily at the same LTV because NOI is larger relative to price.

Does a rising cap rate environment help or hurt debt yield? It depends on which direction values move. If values fall (cap rates rise because prices compress) and NOI stays flat, the borrower asking for 70% LTV is now asking for less dollars — which can improve debt yield. But if cap rates rise because NOI falls, debt yield compresses even as the cap rate rises. The direction of the NOI change matters more than the cap rate direction itself.

How does the Mortgage Bankers Association define cap rate benchmarks? The Mortgage Bankers Association tracks cap rate surveys by property type and geography. Those benchmarks are useful for understanding market pricing, but lenders apply their own underwriting standards to income and value independently of what the market cap rate implies.

What is a typical debt yield floor for a 5% cap rate multifamily property? It depends entirely on the LTV. At 60% LTV, a 5% cap rate implies roughly an 8.3% debt yield — clear of most agency and conventional floors. At 70%, the implied debt yield drops to about 7.1% — below most CMBS floors and some conventional lenders. Run the CRE loan sizing calculator to model what debt yield your specific LTV request implies before approaching a lender.
