What DSCR measures
Debt service coverage ratio divides a property's net operating income by its annual debt service. At 1.00 the property exactly covers its own loan. Below that it needs money from your pocket every year. Above it, there is margin.
The reason this number matters to investors specifically is that DSCR loans underwrite the property rather than the borrower. There is no W-2 review, no tax returns, no debt-to-income calculation on your personal finances. The building qualifies on its own merits, which is what makes these loans workable for self-employed investors and for anyone who has already hit the conventional limit on financed properties.
Roughly where the bands sit
- Below 1.00 — negative coverage. Very few lenders will write it, and those that do want large reserves and a bigger down payment.
- 1.00 to 1.19 — thin. Available from some lenders at a rate premium.
- 1.20 to 1.24 — borderline; many programmes set their floor right here.
- 1.25 and above — comfortably inside typical guidelines.
These are conventions rather than rules, and they move with the credit cycle. Individual lenders set their own floors, and a strong credit score or a larger down payment will often buy tolerance for a weaker ratio.
The two DSCRs, and why they disagree
There is a real ambiguity in how the ratio gets calculated, and it catches people out.
The underwriting version — the one at the top of this page — uses true net operating income: rent, less vacancy, less every operating expense including management and maintenance reserves. It tells you whether the property genuinely supports the debt.
The lender quick version divides gross monthly rent by PITIA (principal, interest, taxes, insurance and association dues). It ignores vacancy, management, maintenance and capital reserves entirely, so it always reads higher. Many DSCR lenders quote this one, which is why a deal can show 1.30 on a lender's worksheet and 1.05 in reality.
Both appear above deliberately. Qualify with the lender's number; decide with yours.
Where the ratio comes from
Lenders normally take the lower of the current lease and market rent from a form 1007 rent schedule, so an above-market lease will not necessarily help you. On short-term rentals, some programmes use a trailing twelve months of actual revenue and others refuse the asset class altogether — worth confirming before you underwrite an Airbnb on projected income.
Common questions
What DSCR do lenders require?
Most programmes sit at 1.20 or 1.25 as a minimum, though some will go to 1.00 or even below with a larger down payment and a stronger credit profile. Floors move with credit conditions, so confirm with the specific lender rather than assuming a market-wide standard.
Is a DSCR loan the same as a conventional investment mortgage?
No. A conventional investment loan underwrites you — income, tax returns, debt-to-income ratio — and caps how many financed properties you can hold. A DSCR loan underwrites the property's cash flow instead. That flexibility usually comes at a higher rate, a larger down payment, and sometimes a prepayment penalty in the first few years.
Do DSCR loans require a down payment?
Typically 20 to 25 per cent, and more if the ratio is weak. Some lenders will lend to 80 per cent loan-to-value at strong coverage and drop to 70 or 75 per cent as the ratio thins.
Should vacancy be included in the calculation?
For your own decision-making, yes — no property is occupied every month of every year, and turnover costs real money. Lenders often exclude it from their quick ratio. That difference is exactly why this page shows both numbers.
Can I use projected rent instead of a signed lease?
Usually yes for an unoccupied property, based on an appraiser's market rent estimate on form 1007. Where a lease exists, most lenders take the lower of actual and market rent, so an above-market lease rarely improves the underwritten ratio.
