A DSCR loan is a mortgage for rental property that is underwritten primarily on the property's own income rather than the borrower's personal income. Instead of pay stubs and tax returns, the lender asks a simpler question: does the rent cover the mortgage payment with room to spare?
That makes DSCR loans popular with self-employed investors, people scaling past a few properties, and BRRRR investors who need a long-term refinance after a renovation. Here are the three numbers that decide whether one works for your deal.
What DSCR Actually Measures
DSCR stands for debt service coverage ratio:
DSCR = net operating income (NOI) ÷ annual debt service
NOI is the property's rental income after operating expenses (taxes, insurance, vacancy, maintenance, management) but before the mortgage. Annual debt service is the total of twelve mortgage payments — principal and interest, and often taxes and insurance depending on how the lender calculates it.
A DSCR of 1.0 means the property exactly covers its payment. Below 1.0, it loses money every month. As an industry benchmark, DSCR lenders often require roughly 1.20-1.25x — meaning the income must exceed the payment by 20-25%. That cushion protects both you and the lender against vacancies and surprise repairs. A property with $18,000 of NOI and $14,400 of annual debt service has a DSCR of 1.25x, right at the typical threshold.
If your deal falls short, the levers are limited: a larger down payment (smaller loan, smaller payment), higher documented rent, or a property with better income relative to price.
The Seasoning Period
Lenders generally will not refinance based on a brand-new, unproven value or rent figure the day after you finish a rehab. A seasoning period is the minimum time you must own the property — and often show actual rental history — before a DSCR refinance based on the new appraised value.
Common seasoning requirements run about 3 to 6 months, though they vary by lender and program. For a BRRRR investor, this matters enormously for planning: your short-term financing (hard money or cash) has to carry the deal through the rehab plus the seasoning window before the long-term loan pays it off. Budget those extra months of interest, taxes, insurance, and utilities into the deal from the start, because they come out of your profit either way.
Some lenders will use a signed lease; others want to see rent actually hitting a bank account for a few months. Ask before you buy, not after.
Refinance LTV: How Much You Can Pull Out
The third gatekeeper is the refinance LTV (loan-to-value): the share of the property's after-repair appraised value the lender will lend. For DSCR refinances, this is often around 75-80% of ARV, subject to the DSCR test above — whichever produces the smaller loan wins.
Say your renovated rental appraises at $280,000. At 75% LTV, the maximum loan is $210,000. If your total cash into the deal — purchase, rehab, closing and holding costs — was $205,000, the refinance returns nearly all of it. If you were all-in at $230,000, you are leaving $20,000 parked in the property. That gap between all-in cost and (ARV × LTV) is the single most important calculation in a BRRRR, and it is worth running before you make an offer, not after the appraisal.
The free Shouldirefi Deal Analyzer runs this math for you — enter your purchase price, rehab budget, expected rent, and ARV, and it estimates your DSCR, your likely refinance proceeds, and how much cash would remain in the deal.
The Bottom Line
DSCR loans trade personal income documentation for property performance. To use one well, know your three numbers before you commit: a DSCR comfortably above the typical 1.20-1.25x benchmark, a plan that survives a 3-6 month seasoning period, and an all-in cost that fits inside 75-80% of a realistic after-repair value.
