DSCR vs LTV: What Really Gates Your Multifamily Loan
Short answer: DSCR or LTV gates your multifamily loan — whichever produces the smaller loan wins. LTV caps you at a percentage of value; DSCR caps you at the loan the property's NOI can cover. On roughly half of 5–20 unit deals, DSCR is the binding constraint, so always quote the lower number.
If you've ever watched a 5–20 unit deal die at the underwriting desk, the postmortem usually comes back to one of two ratios: Debt Service Coverage Ratio (DSCR) or Loan-to-Value (LTV). Both constrain your loan size. Only one is usually the binding constraint. Knowing which — before you quote your borrower — is the difference between a clean close and a painful re-quote.
What decides your max loan: DSCR or LTV?
- LTV is the price ceiling: lenders will lend up to a percentage of the appraised value (or purchase price, whichever is lower).
- DSCR is the cash-flow ceiling: lenders will lend up to whatever monthly payment the property's net operating income can comfortably cover.
A typical 5–20 unit lender posts something like 75% LTV, 1.25x DSCR. You hit one ceiling first. That's your max loan.
A worked example
Subject: 8-unit, $1,200,000 purchase, $108,000 NOI, 7.5% rate, 30-year amortization, IO off.
- LTV ceiling: 75% × $1,200,000 = $900,000.
- DSCR ceiling: $108,000 / 1.25 = $86,400 of annual debt service. At 7.5% / 30yr, that's roughly a $1,030,000 loan.
LTV wins. Your max loan is $900,000. The borrower brings $300,000 + closing.
Now drop the NOI to $84,000 (one vacancy + a roof reserve you forgot). DSCR ceiling falls to $67,200 / yr ≈ $800,000 loan. DSCR is now the binding constraint and the LO has to either increase the down payment, find income (laundry, RUBS, parking), or restructure the financing.
Why does it matter which ceiling binds?
Most LO conversations start with "what's my max loan?" — and most LOs answer with the LTV number because it's easier to compute in your head. But on roughly half of the small-multifamily deals we see, DSCR is the actual ceiling. If you quote LTV when DSCR is binding, you over-promise and re-quote. That's a credibility tax with the buyer's agent and the borrower.
Practical workflow
- Pull the trailing-12 NOI from the rent roll and seller-supplied operating statements. Discount aggressively for vacancy, management, and reserves.
- Run the DSCR loan max at the proposed rate / amort.
- Run the LTV loan max at the requested LTV.
- Quote the lower number. Always.
In PathIQ, both ceilings are computed automatically the moment you enter a deal. You don't have to remember which one is binding — the report tells you. That alone has saved our LO users a lot of awkward Tuesday phone calls.
Frequently asked questions
Is DSCR or LTV more important for a multifamily loan?
Neither is universally more important — the binding constraint is whichever one produces the smaller loan for your specific deal. LTV caps the loan at a percentage of value, while DSCR caps it at what the property's NOI can cover. Always quote the lower of the two.
What does a DSCR of 1.25 mean?
A DSCR of 1.25 means the property's net operating income is 1.25 times its annual debt service — the rent covers the payment with 25% to spare. A DSCR of 1.0 means rent exactly covers the payment; most lenders on small multifamily want at least 1.25.
How do I calculate my max loan from DSCR?
Divide the property's NOI by the lender's required DSCR to get the maximum annual debt service, then solve for the loan amount at the quoted rate and amortization. In the worked example above, $108,000 NOI ÷ 1.25 = $86,400 of debt service, which supports roughly a $1,030,000 loan at 7.5% over 30 years.
Why did my lender approve a smaller loan than the LTV allowed?
Because DSCR was the binding constraint. If the property's NOI can't cover the payment on the full LTV-based loan, the lender sizes down to hit their required coverage ratio. Weak NOI — from vacancy, understated expenses, or missed reserves — pushes the DSCR ceiling below the LTV ceiling.
Can I increase my loan if DSCR is the constraint?
Yes — raise NOI or lower the payment. Adding income (laundry, RUBS, parking), cutting operating expenses, extending amortization, or negotiating a lower rate all lift the DSCR ceiling. Increasing the down payment doesn't change DSCR but does reduce the loan you need.
