DSCR Calculator

Frequently Asked Questions

What makes DSCR loans different from conventional loans?

DSCR loans qualify based on the rental property's cash flow rather than the borrower's personal income. No W-2s or tax returns are typically required, making them popular with self-employed investors.

Can a property pass DSCR but still have poor cash-on-cash return?

Yes. A DSCR of 1.20 means the property covers debt service with a 20% buffer but says nothing about return on the down payment invested. Always pair DSCR with cash-on-cash analysis.

What is annual debt service?

Annual debt service is the total of all principal and interest payments over a year. It does not include taxes, insurance, or other escrow items - those are operating expenses in the NOI.

How does interest-only financing affect DSCR?

An interest-only period reduces annual debt service and boosts DSCR. Lenders typically underwrite based on the fully amortizing payment, not the IO payment.

What if I cannot reach a 1.20 DSCR?

Options include increasing the down payment, finding a lender with a lower minimum, negotiating a lower purchase price, or improving NOI through higher rents or expense reduction.

How It Works

The Debt Service Coverage Ratio (DSCR) measures whether a property's income can cover its loan payments. The formula is DSCR = Net Operating Income divided by Annual Debt Service, where NOI = gross rental income minus operating expenses (taxes, insurance, maintenance, management, and vacancy - but never the mortgage). A DSCR of 1.00 means income exactly equals debt payments; above 1.00 there is a cushion.

Solving NOI divided by target DSCR gives the maximum annual debt service a lender will support at that coverage ratio, which you can use to back into a maximum loan amount from an amortization schedule.

DSCR loans qualify the borrower based on the property's cash flow rather than personal income or W-2 documentation, making them popular with self-employed investors and those with complex tax returns.

Key Metrics

DSCR = 1.20: The most common minimum threshold for residential DSCR lenders. The property generates 20% more income than the debt service.

DSCR = 1.25: Common threshold for commercial lenders and more conservative residential DSCR programs.

DSCR = 1.35+: Required by some lenders for riskier asset classes or in tighter lending environments.

DSCR below 1.00: The property cannot cover its debt service - a lender will not approve the loan on this basis. This is called negative coverage.

Max debt at target DSCR: NOI divided by target DSCR. This is the maximum annual debt service the property can support at your required coverage level.

Tips

Never include the mortgage payment in operating expenses when calculating NOI - it is the denominator in DSCR, not part of the numerator.

Use actual collected rent rather than potential rent, and include a 5-8% vacancy allowance.

Include all real expenses: management fees, maintenance, insurance, taxes, and a capital reserve - omitting any of these inflates DSCR.

Ask your lender exactly how they define NOI - some use their own expense ratios rather than your actual numbers.

DSCR loan rates are typically 0.5-1% higher than conventional owner-occupied rates, so factor this into your debt service calculation.

FAQ

What makes DSCR loans different from conventional loans?

DSCR loans qualify based on the rental property's cash flow rather than the borrower's personal income. No W-2s, tax returns, or employment verification are typically required. This makes them popular with self-employed investors, retirees, and those with complex tax situations. The trade-off is a higher rate and typically a larger down payment (20-25%).

Can a property pass DSCR but still have poor cash-on-cash return?

Yes. A DSCR of 1.20 means the property covers debt service with a 20% buffer - but it says nothing about your return on the down payment you invested. A high purchase price relative to rent can produce a passing DSCR with minimal actual cash flow. Always pair DSCR with cash-on-cash analysis.

What is annual debt service?

Annual debt service is the total of all principal and interest payments on the loan over a full year. If your monthly mortgage payment (P+I) is $2,000, annual debt service is $24,000. It does not include taxes, insurance, or other escrow items - those are operating expenses in the NOI calculation.

How does interest-only financing affect DSCR?

An interest-only (IO) period reduces annual debt service because there is no principal repayment, which boosts the DSCR. Some investors use IO financing to pass DSCR thresholds during lease-up or renovation. Once the IO period ends and the loan amortizes, DSCR drops. Lenders typically underwrite based on the fully amortizing payment, not the IO payment.

What if I cannot reach a 1.20 DSCR?

Options include: increasing the down payment (lower loan = lower debt service), finding a lender with a lower minimum (some accept 1.0 in strong markets), negotiating a lower purchase price, or improving the property's NOI through higher rents or expense reduction before applying.
