Quick Answers

DSCR Calculator, in 30 seconds.

Direct answers to the most common questions, in plain language. Skim if you're in a hurry; dig deeper below.

What is DSCR?

Answer

Debt Service Coverage Ratio — net operating income divided by debt payment.

DSCR = Net Operating Income (NOI) ÷ Annual Debt Service. A DSCR of 1.25 means the property earns 25% more than its mortgage payment. Lenders use this to size investment-property loans without checking personal income.

What DSCR do I need to get a loan?

Answer

1.20 minimum for most lenders; 1.25+ for best terms.

Most DSCR lenders require 1.20+ for approval. 1.25–1.40 gets you better rates. Below 1.0 means the property doesn't cover its own debt — you'd need to subsidize from personal income, and most DSCR lenders won't fund.

Are DSCR loans no-doc?

Answer

No personal income docs, but property cash flow is verified.

DSCR loans skip W-2s, tax returns, and DTI checks. Instead, lenders verify rent (lease or market analysis) and property expenses. Faster close, but typically higher rates than conventional and require 20–25% down.

Can I get DSCR on a short-term rental?

Answer

Yes, but lenders use 12-month average gross.

STRs (Airbnb, VRBO) qualify with most DSCR lenders. They use a 12-month documented gross rents (from AirDNA, statements) or the lower of market lease rate. Some lenders cap the rent assumption at market long-term lease rate.

How it works

How dscr calculator works.

The mechanics in short answers — no jargon, no upsell.

01

Start with gross rent.

Monthly rent × 12. For STRs, use 12-month gross from your data.

02

Subtract operating expenses for NOI.

Property tax, insurance, HOA, maintenance, vacancy reserve, property management. NOT mortgage payment — that's debt service.

03

Divide by annual debt service.

Annual principal + interest payments. NOI ÷ annual debt = DSCR.

04

Compare to lender thresholds.

Most DSCR lenders need 1.20+. 1.25 is the sweet spot. Above 1.40 unlocks best pricing.

Written for borrowers, not bankersPlain-language, jargon-freeReviewed quarterly
What's a good DSCR?

1.25 is the standard "good" — comfortably above the typical 1.20 lender floor, with cushion for vacancy and surprise expenses. 1.40+ is excellent and unlocks the cleanest pricing. Below 1.0 means the property doesn't cover its own debt.

How do lenders calculate NOI?

Most DSCR lenders use a standard formula: gross rent × (1 − vacancy %) − property tax − insurance − HOA − management fee (5–10%) − maintenance reserve (often 5%). Some allow you to provide actuals; many use a standardized expense estimate.

Can I count appreciation in DSCR?

No. DSCR is strictly cash-on-cash for the loan period. Appreciation is irrelevant to debt-service coverage. It matters for total return but not for DSCR qualification.

Are DSCR loans recourse or non-recourse?

Most are recourse to the borrower, often via personal guarantee. Some lenders offer non-recourse on larger commercial deals (5+ units). Read the note — the personal guarantee is usually the catch.

What's the typical down payment?

20–25% is standard for DSCR loans on 1–4 unit residential. 25–30% for STRs. 25–35% for commercial multifamily. Higher than conventional, lower than commercial bank financing.

Does my personal income matter at all?

For most DSCR lenders, no — that's the whole point. Some lenders run a soft credit pull and require 660+ credit. A few require a personal financial statement showing liquidity (typically 6 months of mortgage payments in reserves).

How does vacancy factor in?

Most lenders impute 5% vacancy automatically (some 7.5% or 10% for higher-risk markets). Even if your unit has been 100% occupied, the lender bakes vacancy into the NOI calculation. Plan for it.

Can I refinance into a DSCR loan?

Yes — DSCR refinances are common for investors with multiple properties who don't want their personal DTI examined again. Cash-out DSCR refis are also widely available, up to ~75% LTV.

What DSCR actually measures

DSCR answers one question: does this property earn enough to pay its own mortgage? A DSCR of 1.0 means it breaks even — net rent equals debt service.

Anything above 1.0 is cushion. Lenders want enough cushion that vacancy, maintenance surprises, or rate hikes don't blow up the deal.

NOI is not cash flow

NOI excludes the mortgage payment. Cash flow includes it.

NOI = gross rent − operating expenses.

Cash flow = NOI − annual debt service.

DSCR uses NOI in the numerator, debt service in the denominator. They're distinct numbers and the difference matters.

The thresholds that matter

Under 1.0: most lenders won't fund. Property isn't self-sustaining.

1.0–1.19: a few specialty lenders, premium pricing, often a higher down payment required.

1.20–1.39: mainstream DSCR territory.

1.40+: cleanest pricing, best rates, lowest down payment.

The gotchas

Lenders use their imputed expense formula, not yours. Even if your unit has $0 management cost (self-managed), most lenders bake in 5–10%.

STRs get treated as long-term-rental equivalents by some lenders — your $5k/month STR cash flow might be assessed as $2,500/month LTR rent.

Cash reserves: most DSCR lenders want to see 3–6 months of PITI in your bank at close.

Common DSCR mistakes

  • Using your actual expenses instead of lender imputed expenses.
  • Assuming STR gross will fully count — many lenders haircut it.
  • Forgetting to factor in vacancy reserve.
  • Calculating DSCR on cash flow (denominator should be debt service).
  • Ignoring reserves requirement at close.
