DSCR Loan Calculator
Calculate the debt service coverage ratio (DSCR) on a rental property investor loan. DSCR loans qualify the property's rental income — not your personal income — so they suit self-employed investors and house hackers. Most lenders require DSCR of 1.0 or 1.25; some no-ratio products go as low as 0.75 with a rate adjustment.
What Is a DSCR Loan?
A DSCR (debt service coverage ratio) loan is a non-QM rental property mortgage that qualifies the property's rental income against its monthly debt service, instead of pulling tax returns and W-2s from the borrower. The formula is simple: DSCR = monthly gross rent ÷ monthly PITIA (principal, interest, taxes, insurance, association dues). A DSCR of 1.0 means rent exactly covers debt service; 1.25 means rent covers 125% of debt service (a common Fannie Mae multifamily threshold); 1.5+ is strong investor cash flow. Per FDIC commercial real estate underwriting guidance, regulated lenders generally underwrite DSCR ≥ 1.20-1.25 on income-producing properties. Non-bank DSCR lenders push lower (1.0 with rate adjustment, 0.75 "no-ratio" with 30%+ down). Last updated May 2026.
Who Uses DSCR Loans?
DSCR loans suit four investor profiles: (1) self-employed borrowers whose tax returns understate true income (large depreciation deductions, business expense write-offs); (2) portfolio investors with 5+ rentals who hit Fannie Mae's 10-property cap and need a non-QM lender; (3) house hackers moving out of an owner-occupied home and converting it to a rental who don't want to wait 12 months for rental history; (4) foreign nationals with no US tax returns or credit. The trade-off vs a conventional Fannie/Freddie investor loan: rates run 1.0-1.5% higher (typical 2026 quote: conventional investor 7.0-7.25%, DSCR 7.875-8.5%), origination fees are 1.5-2.5% (vs 0.5-1.0% conventional), and prepayment penalties are common (3-2-1 step-down or 5-year flat). The benefit: closes in 21-30 days vs 45-60 days conventional, and qualifies on rental property income alone.
How to Improve Your DSCR
Three levers improve DSCR: increase rent, reduce expenses, or restructure debt. (1) Rent: lenders use the lower of actual lease rent and Form 1007 market rent appraisal; if your appraised market rent is higher than current rent, push for a rent increase before applying. (2) Expenses: shop insurance (high-deductible policies on investor properties save 30-40%), appeal property tax assessments after purchase if comparable sales support a lower value, and re-tier HOA fees if a master association covers items you can self-manage. (3) Debt structure: extend the amortization term from 30 to 40 years (lowers payment ~10%), choose interest-only first 10 years (lowers payment ~25% during IO period), or accept a higher down payment (each 5% extra reduces P&I about 6-7%). Per Fannie Mae multifamily research, lenders re-test DSCR annually on portfolio loans, so building a buffer above the qualifying ratio matters.
DSCR Loan vs Conventional Investor Loan — Which Is Right?
Use conventional investor loan when: you have W-2 income, < 4-5 financed properties, and want the cheapest rate. Use DSCR loan when: you're self-employed with tax returns that don't reflect true income, you have 5-10+ rentals, you're buying a property where rents already comfortably cover debt, you need to close fast (under 30 days), or you're a foreign national. A specific 2026 example: $400K duplex with $3,500/mo combined rent and $2,800/mo PITIA gives DSCR of 1.25 — qualifies easily as DSCR loan but might not pass a conventional cash-flow test if your personal DTI is already stretched. Run both and compare total cost over your expected hold period — DSCR's higher rate is sometimes worth it for the speed and qualification flexibility.
Frequently Asked Questions
What DSCR do most lenders require?
Most non-QM DSCR lenders set 1.0 as the minimum (rent exactly covers PITIA) with their best rates kicking in at 1.25+. Some "no-ratio" products go down to 0.75 DSCR but charge 0.5-1.0% higher rate and require 30%+ down payment.
How does DSCR differ from cap rate?
DSCR measures rental income vs debt service. Cap rate measures NOI vs purchase price (a property valuation metric, not financing). A high cap rate property may have low DSCR if heavily leveraged. Both matter — cap rate evaluates the deal, DSCR evaluates the loan.
Are DSCR loans considered conventional or non-QM?
Non-QM (non-qualified mortgage). Because they skip personal-income verification (no tax returns, W-2s, pay stubs), they fall outside the CFPB QM safe harbor. This is why rates are 1-1.5% higher than conventional investor loans.
Can I use projected/market rent or only signed lease rent?
For purchases of vacant properties, lenders use the appraiser's Form 1007 market rent estimate. For occupied properties, the lender uses the lower of current lease rent and 1007 market rent.
Do DSCR loans have prepayment penalties?
Most do — typically 3-2-1 step-down (3% if paid off year 1, 2% year 2, 1% year 3), or 5-year flat (5% any time within first 5 years). Some lenders offer no-prepay options for 0.25-0.5% higher rate. Always read the prepayment rider.
How many DSCR loans can I have?
No federal cap. Each lender has internal portfolio limits — typically 10-20 DSCR loans per borrower, with cross-collateralization required above that. Foreign national borrowers often face stricter caps (5-10 properties).
