Why lenders prefer it to DSCR
DSCR can be engineered. Stretch amortization from 25 years to 40, or price the loan at a promotional rate, and coverage improves without the property earning an extra dollar. Debt yield strips those levers out: it compares the income the asset produces against the dollars the lender put at risk, full stop. That makes it a cleaner measure of downside, which is why it became standard in commercial underwriting after cycles where loans that penciled at origination stopped penciling the moment rates moved. Residential DSCR lenders rarely name it, but the same logic sits underneath their loan sizing.
How it sizes a loan
Run the formula backward and debt yield becomes a loan ceiling: maximum loan = NOI ÷ target debt yield. With $24,000 of NOI and a 10% minimum, the loan tops out around $240,000 no matter what loan-to-value the appraisal would allow. On deals where appraised value is generous relative to income — appreciation-heavy metros, properties bought below market — debt yield rather than LTV usually becomes the binding constraint, and that surprises borrowers who budgeted their proceeds off a percentage of value.
Debt yield = NOI ÷ loan amount × 100. A property with $24,000 of NOI carrying a $260,000 loan has a debt yield of about 9.2%.
Using it as a borrower
Calculate it yourself before you apply, using the NOI a lender will actually credit — in-place rents rather than projections, real taxes at the reassessed figure, an insurance quote rather than the seller’s legacy premium, and a management line even if you plan to self-manage. If your debt yield is thin, the fixes are structural: raise income, cut expenses, or borrow less. It is also a useful personal guardrail on a cash-out refinance, because a loan that leaves debt yield below what a lender would accept today is a loan that will be hard to refinance when the term ends.
Where the NOI comes from
The metric is only as good as the income beneath it, and NOI is the line most easily inflated. Lenders normalize it: they use in-place rents rather than projections, apply a market vacancy factor even on a fully leased building, add a management fee whether or not you self-manage, and often include a replacement reserve. Do the same arithmetic before you apply, because discovering that the lender’s NOI sits well below yours during underwriting means resizing the loan, finding more cash, or losing the deal at the worst possible moment.
