DSCR Loans on Vacant vs. Tenant-Occupied Property: Which Rent Number Actually Qualifies the Deal

You put a 1-4 unit rental under contract at $340,000. If it’s vacant, the appraiser’s market-rent schedule sets your qualifying rent. If a tenant is already in place, the lender doesn’t just take your word — or the lease’s word — for what it rents for. It takes the lower of two numbers, and that choice can be the difference between a loan that closes and a file that gets re-sized three days before funding.

This is the part of DSCR underwriting that catches investors off guard, because it has nothing to do with credit score or down payment. It’s about which rent figure the file is built on, and the rule changes depending on whether a lease exists.

The Two Rent Numbers a DSCR File Can Use

Every DSCR file needs a monthly rent figure to divide against the property’s PITIA (principal, interest, taxes, insurance, association dues) to produce the debt-service coverage ratio. There are only two sources for that number: the appraiser’s comparable-rent schedule — essentially a market-rent opinion based on similar nearby rentals — and an actual signed lease, when one exists.

Which one governs depends entirely on occupancy at closing.

Vacant at Closing: the Appraiser’s Number Is the Only Number

If the property is vacant, there’s no lease to compare against, so the file qualifies off 100% of the appraiser’s market-rent opinion. That number is an estimate of what the unit would rent for today, not what it rented for under a prior tenant, and not what you project you’ll get once you’ve finished cosmetic work. If your business plan assumes a rent increase, that increase has to show up in the comps the appraiser pulls — you can’t underwrite a future rent.

Tenant-Occupied: Why the Lender Takes the Lower of the Two

When a lease is already in place, the lender compares the lease rent against the same appraiser market-rent schedule and qualifies off whichever number is lower. This protects against two different problems from two different directions: a seller who signed a friendly lease above market just before listing to make the DSCR look better than it is, and a legacy lease that’s been flat for years and sits well under what the unit could actually command. Either way, the file gets qualified on the conservative figure, and the gap between the two numbers doesn’t help you until the lease turns over at market rate.

In the legacy-lease row, the deal still qualifies at 0.90x — DSCR programs on 1-4 unit rentals can go as low as 0.75x, indicative and subject to underwriting, with the leverage tier adjusting down as the ratio drops. But that investor is leaving real DSCR cushion on the table against a tenant paying $500 a month under market, cushion that affects pricing and max LTV, not just a line on a worksheet.

The Related-Party Lease Trap

Here’s the constraint that doesn’t show up on a flip or bridge file and catches investors who’ve closed plenty of those: if the tenant is a related party — a parent, sibling, adult child, or an entity the borrower also controls — the lease is disregarded entirely, no matter what rent it states. The file is underwritten as if the unit were vacant, off the appraiser’s market-rent schedule alone. A below-market “family rate” doesn’t just get capped at market; it’s thrown out, which actually helps in that specific case. But a related-party lease written at an inflated rent to game the DSCR gets thrown out too, and the file falls back to the real market number. Either way, the lender isn’t pricing a relationship, only an arm’s-length market.

When This Is the Wrong Call

If you’re buying a property specifically because the in-place lease is well under market and your plan is to raise rent at the next renewal, closing today under DSCR means qualifying on today’s number, not tomorrow’s. If that lower figure doesn’t clear the program’s minimum ratio at the leverage you need, the fix isn’t to argue the appraiser’s comp set — it’s to negotiate a rent-ready vacant close, get the seller to re-lease at market before closing, or wait for the existing lease to expire and resign before you refinance. Forcing a purchase through on a suppressed number just pushes the shortfall into a smaller loan amount or a larger down payment, and in a few cases, the arithmetic doesn’t close no matter how you present it. A deal that only works on paper by using the higher of two numbers instead of the lower isn’t ready to submit — it’s ready to be walked back from the table.

Multifamily (5+ unit) DSCR files follow a parallel logic but weight it against the full rent roll rather than a single lease, since occupancy and lease mix across units changes the math more than one tenant ever could on a 1-4 unit file.
