What Is Debt Yield in Commercial Real Estate — and Why Lenders Care About It

Debt yield is NOI divided by loan amount. It is the underwriting metric CMBS lenders use that LTV and DSCR cannot replicate. Here is how it works.

You size a commercial real estate loan the way everyone is taught: run the loan-to-value, run the debt service coverage ratio, and arrive at a number you are confident in. Then the term sheet comes back lower — sometimes much lower — and neither of the two metrics you ran explains why.

The culprit is usually debt yield. It is the third constraint most borrowers never model, and on the wrong deal it is the one that quietly sets your proceeds. Worse, it does not move for any of the reasons LTV and DSCR move, so the levers you would normally pull do nothing.

This is especially true on CMBS deals, where debt yield is not a sanity check but the headline test. A borrower who sized a deal on a 75% LTV and a 1.25x coverage ratio can still be told the loan is $2 million short — because the debt yield came in under 10%.

What debt yield actually is

Debt yield is net operating income divided by the loan amount, written as a percentage.

Debt Yield = NOI ÷ Loan Amount

A property generating $1,200,000 of NOI against a $12,000,000 loan has a debt yield of 10.0%. That is it. There is no interest rate in the formula, no amortization schedule, and no appraised value. It answers one blunt question for the lender: if I foreclosed tomorrow and took the building's income, what unlevered return would I earn on the money I lent?

Why it is immune to rate and amortization games

This is the property that makes lenders trust it. Both of the metrics borrowers usually rely on can be flattered without the deal actually getting safer.

Debt service coverage improves if you negotiate a lower rate or stretch amortization from 25 to 30 years, because the annual payment shrinks. Loan-to-value improves if the appraisal comes in high. Neither change puts a single extra dollar of income into the property.

Debt yield refuses to play. Because it only looks at income over loan balance, a lower rate, a longer amortization, and a richer appraisal all leave it untouched. The only two ways to raise debt yield are to increase NOI or to borrow less. That rate-proof quality is exactly why CMBS lenders lean on it: a loan that gets securitized and sold to bond investors needs a measure that cannot be engineered at the closing table.

How it differs from DSCR and LTV

Think of the three as answering different questions. LTV asks how the loan compares to the asset's value. DSCR asks whether this year's income covers this year's payment. Debt yield asks how the loan compares to the income itself, with financing terms stripped out.

That is why two deals with an identical 1.25x DSCR can have wildly different debt yields — one financed at 5% over 30 years, the other at 7% over 25 years. The coverage ratio looks the same; the underlying income cushion does not.

CMBS and the 10% floor

Conventional banks often accept a debt yield of 8–9%. Agency lenders sit in a similar band. CMBS lenders typically draw the line at 10% or higher, because their loans are non-recourse, pooled, and difficult to restructure once sold. The higher floor is the price of that structure — see what is a good debt yield for the full range by lender type.

Loan sizing uses all three at once

In practice a lender runs LTV, DSCR, and debt yield together and lends the smallest result. The constraint that produces the lowest maximum loan is the binding one — and it is the only limit that actually determines your proceeds. The CRE loan sizing calculator runs all three at once.

Consider a $2,000,000 NOI property worth $25,000,000. At a 70% max LTV the loan caps at $17,500,000. At a 10% debt yield it caps at $20,000,000. At a 1.25x DSCR it might support $21,000,000. The lender funds $17,500,000 — LTV binds here, but flip the appraisal down and debt yield takes over.

How to improve a thin debt yield

There are only two honest moves. Raise NOI — through higher rents, lower expenses, or burning off concessions — or reduce the loan you are asking for and bring more equity. No rate negotiation, amortization tweak, or appraisal will rescue a debt yield that is too low.

Because the metric is unforgiving, the smartest borrowers run it first. Before you submit anything, it is worth a moment to check whether your deal clears lender thresholds across debt yield, DSCR, and LTV together, so the binding constraint is something you chose to live with rather than a surprise on the term sheet.

Debt yield is not complicated. It is one division. But it is the division that LTV and DSCR cannot stand in for — and the one most likely to decide how much a lender will actually give you.
