A DSCR loan is underwritten based on a property's rental income rather than the borrower's personal income — no W-2s, no tax returns, no debt-to-income calculation on your paycheck. What lenders want instead is a clear picture of the property's cash flow relative to its debt payment. This guide works as a template: the framework lenders use and the documents you'll want gathered before you start shopping offers, since specific rates, fees, and minimum thresholds change constantly and vary by lender — always get current terms directly from multiple lenders rather than relying on a number you saw somewhere else.
How Lenders Calculate DSCR
DSCR = Property's Net Operating Income ÷ Annual Debt Service
A ratio above 1.0 means the property's income covers its debt payments; below 1.0 means it doesn't, at least on paper. Many DSCR lenders set a minimum ratio somewhere in the 1.0-1.25x range as a general underwriting standard, though the exact minimum — and how flexible a lender is below it — varies by lender and can shift with market conditions, so confirm current requirements directly rather than assuming a specific number applies to your deal.
The Documents and Data You'll Need to Gather
Use this as your prep checklist before applying:
- Property address and purchase contract or current appraised value
- Signed lease (for an occupied property) or a market rent survey/appraisal rent schedule (for a vacant or to-be-rented property)
- Annual property tax bill
- Homeowners/landlord insurance quote or current policy
- HOA dues, if applicable
- Entity formation documents (LLC operating agreement, EIN) if purchasing through an entity
- Credit report authorization and a recent credit score pull
- Bank statements showing reserves — many DSCR lenders require a set number of months of mortgage payments in reserve
- Down payment source documentation
A Simple DSCR Worksheet (Illustrative)
These figures are illustrative only, to show how the ratio comes together:
- Monthly market rent: $2,000 → Annual gross rent: $24,000
- Less vacancy allowance and operating expenses used in the lender's NOI calculation: -$8,400
- NOI: $15,600
- Estimated annual debt service on the proposed loan: $13,200
DSCR = $15,600 ÷ $13,200 = 1.18
Run this worksheet with your actual numbers before applying so you know roughly where you stand — and rerun it under a few different rate and loan-amount scenarios, since the loan amount a lender will approve is often driven by what DSCR the deal can support, not the other way around.
Comparing DSCR Loan Offers
Because rates and terms change constantly, compare offers on structure rather than a single headline rate:
- Fixed rate vs. adjustable-rate structure, and how long any fixed period lasts
- Prepayment penalty terms — many DSCR loans carry a declining prepayment penalty over several years, which matters a great deal if you plan to refinance or sell early
- Points and origination fees, which affect your real cost of capital beyond the quoted rate
- Minimum DSCR required and how the lender treats a deal that falls slightly below it
- Interest-only period availability, which lowers debt service and raises your DSCR on paper but doesn't build equity through principal paydown
- Maximum loan-to-value (LTV) offered at your DSCR level
Get at least three quotes on the same property with the same assumptions so you're comparing structure to structure, not just headline rate to headline rate.
Common Pitfalls
- Using optimistic pro forma rent instead of the appraiser's market rent schedule, which the lender will use regardless of what you project.
- Ignoring the prepayment penalty structure and getting locked into a costly exit if your plans change.
- Not budgeting reserves the lender will require to close, which can catch borrowers off guard late in the process.
- Assuming last year's rate or terms still apply — DSCR loan pricing moves with the broader lending market, so treat any number you haven't confirmed this week as outdated.
