Debt yield: the number that ignores your rate

A borrower with strong income assumes the loan will be large. The property throws off plenty of cash, the payment is easily covered, the numbers work. Then the lender comes back with a loan smaller than the borrower expected and points to a ratio the borrower has never heard of. The first metric, debt-service coverage, is the one everyone knows. The second, debt yield, is the one that quietly caps the loan, and it is deliberately built to ignore how cheap the borrower’s rate is.

Debt-service coverage asks whether the income covers the payment. Debt yield asks whether the income justifies the loan size at all, no matter how low the rate goes.

DSCR: can the income cover the payment

The debt-service coverage ratio is net operating income divided by annual debt service. A property with $600,000 of net operating income and $480,000 of annual loan payments has a DSCR of 1.25, meaning it produces $1.25 of income for every $1 of debt service. Lenders require a cushion above 1.0, commonly in the range of 1.20 to 1.25 depending on the asset and the lender, so that a dip in income does not immediately put the loan underwater. DSCR is intuitive and it is what most borrowers underwrite to.

DSCR has a weakness the lender knows well: it depends on the payment, and the payment depends on the rate and the amortization. Lower the rate, and the debt service falls, and the same income suddenly supports a much larger loan at the same DSCR. In a low-rate world, DSCR alone would let leverage balloon, because cheap debt is easy to cover. That is exactly the risk the second metric exists to control.

Debt yield: the metric that ignores your rate

Debt yield is net operating income divided by the loan amount. A $600,000 income on a $6 million loan is a 10 percent debt yield. It has no rate in it, no amortization, no payment. It measures one thing: how much income the property produces per dollar borrowed, which is the lender’s real recovery position if it has to foreclose the day after closing.

Because debt yield ignores the rate, it does not loosen when rates fall. A lender with a 10 percent debt-yield floor will lend no more than ten times net operating income, whether the rate is 4 percent or 8 percent. That floor is the lender’s protection against low rates inflating loan sizes past what the underlying income can safely support.

Why the lender lends the lesser

A lender sizes a loan against every constraint it has and offers the smallest result. DSCR is one constraint. Debt yield is another. LTV is a third. The loan comes in at whichever produces the lowest number.

Put figures on it. A property with $600,000 of net operating income seeks financing. At a 1.25 DSCR and an interest-only payment at 6 percent, the income supports $480,000 of debt service, which at 6 percent interest-only implies a loan of about $8 million. The borrower models $8 million. But the lender also applies a 10 percent debt-yield floor, which caps the loan at $6 million regardless of the rate. The lender lends the lesser: $6 million. The borrower who solved only for DSCR is $2 million short and does not understand why, because by the coverage math the larger loan was easily serviceable. Debt yield is the reason, and it never appeared in the borrower’s model.

The consequence: model the floor, not just the coverage

The gap between the loan a borrower expects and the loan a lender offers is often the gap between DSCR and debt yield. A borrower underwriting only coverage will consistently overestimate proceeds in a low-rate environment, because coverage rewards a cheap rate and debt yield refuses to. The structuring lesson is to size the deal on whichever constraint binds, and in low-rate periods that is usually debt yield. It caps the loan, which caps the leverage, which changes how much equity the deal needs and therefore what return it can promise. A sponsor who builds a capital stack on DSCR-implied proceeds, then gets debt-yield-constrained proceeds, has an equity hole to fill before the deal even closes. Ask the lender for its debt-yield floor early, run the loan against it first, and treat the coverage number as the second test, not the first.
