CMBS Debt Yield Requirements: Why the 10% Floor Matters

CMBS lenders are known for paying close attention to debt yield. A common screening floor is around 10%, though exact requirements vary by lender, property type, market, sponsorship, and capital markets conditions.

The reason is simple: CMBS loans are often pooled, securitized, and sold to bond investors. Once a loan is in a securitization, flexibility can be limited. Lenders therefore want a metric that does not depend on negotiable loan terms or optimistic valuations.

Why CMBS focuses on debt yield

Debt yield strips the loan down to income and balance.

Debt Yield = NOI / Loan Amount

It does not care about the interest rate. It does not care about amortization. It does not care about appraised value. That makes it useful when a lender wants a stable income-based risk measure.

The 10% idea

A 10% debt yield means the property produces annual NOI equal to 10% of the loan balance. Put another way, $1,000,000 of NOI supports a $10,000,000 loan at a 10% debt-yield floor.

Max Loan = NOI / Minimum Debt Yield

At 10%, the shortcut is simple: multiply NOI by 10. At 9%, multiply NOI by about 11.11. At 8%, multiply NOI by 12.5.

Why a deal can pass DSCR and still fail CMBS debt yield

DSCR depends on debt service. If rates are low or amortization is long, DSCR may look acceptable even when the loan is large relative to NOI. Debt yield catches that because it ignores the payment structure.

That is why a borrower can show 1.25x DSCR and acceptable LTV but still see proceeds reduced by a CMBS lender.

Property type matters

Riskier or more volatile assets can require higher debt yield. Hotels, transitional retail, older office, or secondary-market properties may face more conservative sizing than stable multifamily or industrial assets.

How to screen a CMBS loan request

Start with NOI and the lender's minimum debt yield. Use the debt yield calculator to test the ratio and the maximum loan supported. Then use the CRE loan sizing calculator to compare the CMBS debt-yield cap against DSCR and LTV.

CMBS debt yield is not complicated, but it is unforgiving. That is exactly why lenders use it.
