Google “what is a good DSCR” and nearly every result is a lender trying to sell you a DSCR loan. They'll tell you the magic number is 1.25, hand you a rate quote form, and stop there. That answer isn't wrong — it's just the lender's half of the story. The investor's half is what 1.25 actually does to your deal: it caps how much you can borrow, which caps how much you can pay for the property. This post covers both halves, with the worked math.
The short answer
A good DSCR for a rental property is 1.25 or higher. That means the property's net operating income covers its annual loan payments 1.25 times over — a 25% cushion between what the property earns and what it owes. Between 1.0 and 1.25 the property covers its debt with little margin for error. Below 1.0, the property doesn't earn enough to pay its own mortgage, and you make up the difference from your paycheck every month.
| DSCR band | What it means for you | What it means to a lender |
|---|---|---|
| Below 1.0 | Modeled income is below modeled debt service under this formula | Program-specific; request written requirements |
| 1.0 – 1.15 | Thin modeled coverage; stress vacancy and expenses | Program-specific; request written requirements |
| 1.15 – 1.25 | Some modeled cushion; test property downside | Program-specific; request written requirements |
| 1.25 – 1.50 | Larger modeled cushion under this formula | Does not establish approval, pricing, or leverage |
| 1.50+ | Higher modeled coverage; verify every input | Does not establish approval, pricing, or leverage |
The 1.25 convention isn't arbitrary. It's roughly the cushion that lets a property absorb a vacant month, a repair bill, and a tax reassessment in the same year without missing a mortgage payment. Lenders converged on it across decades of commercial underwriting because portfolios above 1.25 rarely default and portfolios below 1.1 default often.
A 60-second refresher on the formula
DSCR is net operating income divided by annual debt service:
If the property has no mortgage, there's no denominator — DSCR on a cash purchase is undefined, and honest tools report it as N/A rather than pretending it's infinite. For the full walkthrough of the formula, including which expenses belong in NOI, see our guide to calculating DSCR. Here we'll focus on what the number means once you have it.
Worked example: a $250K duplex at 7% with 25% down
Say you're underwriting a $250,000 duplex renting for $1,300 per unit — $2,600/month, $31,200/year gross. You put 25% down ($62,500) and finance $187,500 at 7% over 30 years. The monthly principal-and-interest payment is $1,247, or $14,969/year in debt service. (Check any loan with our mortgage payment calculator.)
Now build NOI with honest expense assumptions:
- Gross rent: $31,200
- Vacancy (8%): −$2,496
- Property taxes (1.5% of price): −$3,750
- Insurance: −$1,600
- Repairs & maintenance (8%): −$2,496
- CapEx reserve (5%): −$1,560
- Property management (8%): −$2,496
Total operating expenses: $14,398. NOI: $16,802/year — about $1,400/month.
The property covers its mortgage — barely. At 1.12, roughly $153 of monthly cash flow stands between you and feeding the deal. It clears break-even but fails the 1.25 bar, which puts it squarely in the “thin but workable” band. So what would it take to make this deal pass? That's the question the lender SERP never answers.
What 1.25 means for your loan: the max-loan calculation
Flip the formula around. Instead of asking “what's my DSCR at this loan amount,” ask “what loan amount gets me to 1.25?” Divide NOI by the target ratio:
At 7% over 30 years, every $100,000 borrowed costs $665.30/month. A $1,120 payment therefore supports a loan of about $168,400 — not the $187,500 you planned to borrow. To buy this duplex at $250,000 with a 1.25 DSCR, you'd need roughly $81,600 down (32.7%) instead of $62,500 (25%). That extra $19,100 of equity is the real-world price of the cushion.
What 1.25 means for your offer price
Or hold the down payment at 25% and solve for price instead. At 25% down, the loan is 75% of the purchase price, and at 7%/30yr that loan costs about 5.99% of the purchase price in annual debt service. Setting that equal to the $13,442 maximum:
To hit a 1.25 DSCR with 25% down, your maximum offer on this duplex is about $224,500 — roughly $25,500 (10%) below asking. (A lower price also trims property taxes slightly, which nudges NOI up — so $224,500 is mildly conservative.) This is the negotiating math that a DSCR target actually gives you: not a pass/fail grade on the listing, but a defensible ceiling on what you can pay. Our free DSCR calculator runs this in both directions — DSCR at your numbers, and the max loan at any target ratio.
The down-payment lever: how each 5% moves DSCR
Price and loan size are two handles on the same ratio. Hold the $250,000 price fixed and walk the down payment up in 5-point steps, and you can watch the duplex climb toward 1.25. Same NOI ($16,802), same 7% / 30-year loan — only the amount borrowed changes:
| Down payment | Loan amount | Annual debt service | DSCR |
|---|---|---|---|
| 20% ($50,000) | $200,000 | $15,967 | 1.05 |
| 25% ($62,500) | $187,500 | $14,969 | 1.12 |
| 30% ($75,000) | $175,000 | $13,971 | 1.20 |
| 35% ($87,500) | $162,500 | $12,973 | 1.29 |
Every extra 5% down buys roughly 0.07–0.08 of DSCR here, and the 1.25 bar falls between the 30% and 35% rows — the same ~33% down the max-loan math landed on. But “just put more down” isn't free. The $25,000 that moves you from 25% to 35% is cash that now sits in the walls earning the property's return instead of yours: it lifts DSCR while it drags your cash-on-cash return, and when the loan constant tops the cap rate you can buy your way into negative leverage doing it. The right amount down is the one that clears the lender's bar with a little room to spare — not the maximum you can scrape together.
The lender's DSCR is not your DSCR
Here's the trap in taking the lender's number at face value. Some DSCR programs use a rent-to-PITIA calculation rather than the investor's NOI-based ratio. A common form is:
On our duplex: PITIA is $1,247 (P&I) + $313 (taxes) + $133 (insurance) = $1,693. Lender DSCR = $2,600 ÷ $1,693 = 1.54. The same hypothetical property scores 1.12 under the article's NOI-based operating scenario. The difference comes from the selected numerator and denominator; confirm the actual program's treatment rather than assuming it excludes every operating item.
This is why “the lender approved it” and “the deal is good” are different claims. The lender is underwriting their downside (foreclosure recovery), not your return. A program ratio can look stronger than an operating ratio when the formulas use different inputs, so approval should not be treated as validation of the property's cash flow. If you're comparing loan products themselves, our DSCR loans guide covers rates, LTV tiers, and when they beat conventional financing.
Stress-test the ratio, not just the snapshot
A DSCR is a photograph of one set of assumptions. Before trusting it, poke it:
- Rent −10%: our duplex's NOI drops to about $14,587 and DSCR falls to 0.97 — under water. A deal that starts at 1.12 has an 8% rent cushion before it stops covering its own mortgage (break-even rent here is about $2,385/month).
- Rate +1 point: at 8%, the same $187,500 loan costs $1,376/month and the DSCR at asking drops from 1.12 to 1.02. If you're buying with a rate-and-term refinance thesis, run the exit rate, not the teaser.
- Taxes reassessed: many counties reassess on sale. If taxes jump from the seller's $2,800 to your $3,750, that alone moves DSCR by about 0.06 on this deal.
A good DSCR isn't just 1.25 today — it's a ratio that stays above 1.0 in the bad year. That's the standard commercial underwriters actually apply, and it's free to apply yourself with a cash flow calculator and ten minutes of pessimism.
When a sub-1.25 DSCR is still a buy
The 1.25 bar is a lending convention, not a law of investing. Legitimate reasons to buy below it:
- A concrete rent-growth path. Inherited tenants at $1,050 against a $1,300 market rate is a 1.12-today, 1.35-at-turnover story. Underwrite the turnover cost and timeline, not just the destination.
- House hacking. Owner-occupants measure the deal against their current rent, not against a DSCR. A duplex that scores 0.9 as a pure rental can still cut your housing cost in half.
- A value-add you control. BRRRR and rehab deals are priced on the stabilized DSCR, not the as-is one. Just be honest about which number the lender will see at refinance.
What's not a reason: hoping. A 1.05 DSCR with no story is a property that pays its mortgage only when nothing goes wrong — and something always goes wrong.

FAQ
What is a good DSCR for a rental property?
1.25 or higher is the standard benchmark — the property's net operating income covers its annual debt payments 1.25 times over, leaving a 25% cushion. 1.0-1.25 means the property covers its debt but with thin margin; below 1.0 means the property loses money every month before you even think about capital expenditures. Above 1.5 is strong and usually reflects a high-yield market, a large down payment, or both.
Is a DSCR of 1.0 good?
No — 1.0 is break-even, not good. At exactly 1.0, NOI equals debt service, so one vacant month, one furnace repair, or one insurance premium hike pushes the property into negative cash flow. Most investors treat 1.0-1.15 as a 'yellow zone': acceptable only with a specific plan to raise rents or refinance, never as a steady state.
What DSCR do lenders require in 2026?
Requirements vary by lender, program, borrower, property, state, and date. Ask for the current written DSCR formula, minimum, rent evidence, leverage, pricing, reserves, credit, entity, and documentation rules. Conventional underwriting also varies and can consider income, assets, liabilities, credit, property, and program-specific rental treatment.
How do lenders calculate DSCR differently from investors?
DSCR lenders typically divide gross monthly rent by PITIA (principal, interest, taxes, insurance, association dues). Investors should divide NOI — rent minus vacancy, maintenance, management, and reserves — by annual debt service. The lender version ignores most operating expenses, so a property can score 1.5 with the lender while its true NOI-based DSCR sits near 1.1. Always compute both.
Can a DSCR be too high?
Not in a risk sense — a 2.0+ DSCR property is very safe from a debt-coverage standpoint. But an unusually high DSCR can signal under-leverage: if a big down payment is what's producing the ratio, your cash-on-cash return may be lower than deploying that equity across two properties. It can also flag a high-yield, higher-risk market where lenders demand the extra cushion for a reason.
What is the DSCR on a cash purchase?
Undefined — with no loan there's no debt service, so the ratio has no denominator. Analysis tools (TrueCap included) report DSCR as N/A on cash deals rather than showing a misleading number. For a cash purchase, judge the deal on cap rate and cash-on-cash return instead.
