A DSCR (Debt Service Coverage Ratio) loan qualifies an investor based on the rental income a property generates relative to its mortgage payment, instead of the borrower's personal income, employment history, or tax returns. It's a non-QM (non-qualified mortgage) investor product — widely used across the industry, including by Nashville-area landlords scaling a rental portfolio — rather than a government-backed or agency-insured loan type.
In residential investor lending, a DSCR loan qualifies the deal property-by-property: I take the property's monthly rental income — either the signed lease amount, or, for a purchase, an appraiser's market-rent estimate on Fannie Mae Form 1007 — and divide it by the proposed monthly payment (principal, interest, taxes, insurance, HOA dues if any, or "PITIA"). A ratio of 1.00 means the rent exactly covers the payment. I typically underwrite Nashville-area investors somewhere between 0.75 and 1.25+ DSCR depending on the program: below 1.0 ("no-ratio" or negative-leverage DSCR) is still financeable with most of my lenders, just at a higher rate and often a lower max loan-to-value; above 1.25 usually earns pricing improvements. No tax returns, no W-2s, no personal debt-to-income calculation — the property qualifies itself.
How I actually structure these for Middle Tennessee investors: most of my DSCR lenders run purchases up to 80% LTV and rate-and-term refinances up to roughly 75-80% LTV on a strong-DSCR deal, cash-out refinances a bit tighter, typically 70-75%. Reserve requirements generally run 3-6 months of PITIA, sometimes more on a lower DSCR or a cash-out. Nearly every DSCR loan I close is vested in an LLC or other business entity rather than the investor's personal name — which is one of the biggest reasons investors come to me for this instead of a conventional loan, since Fannie/Freddie financing has to close in an individual's name. Most programs also carry a prepayment penalty structure (commonly a step-down over 3-5 years) in exchange for the looser income documentation, and that's a real trade-off I walk every investor through before we pick a lender.
A real Franklin, Brentwood or Nashville scenario I see often: an investor buying a $320,000 rental duplex in Davidson County with $2,600/month in combined rental income against a $2,200/month PITIA payment lands around a 1.18 DSCR — a clean, comfortably-qualifying deal on almost any of my lenders' grids, with no look at the borrower's personal tax returns at all. Compare that to a short-term-rental purchase in a Williamson County vacation-rental pocket, where I'll often need to use projected STR income (via AirDNA or a comparable market-rent tool, depending on the lender's guidelines) rather than a signed 12-month lease — a very different documentation path that not every DSCR lender supports, which is exactly the kind of thing I'm sorting through with an investor before we pick where to place the loan.
DSCR loans are a non-QM product category, which means there's no single federal agency defining the program the way HUD defines FHA or the VA defines VA loans — guidelines, minimum DSCR, LTV, and reserve requirements vary lender to lender. What's above reflects how I actually structure and place these loans day to day for Nashville-area investors; the numbers on any specific property will depend on the lender, the property type, and current pricing.
