Lender-ready DSCR calculation

DSCR = Net Operating Income / Annual Debt Service
Debt Service Coverage Ratio measures whether your property's income covers its debt payments. A DSCR of 1.0 means the property breaks even -- income exactly equals debt payments. A DSCR of 1.25 means the property generates 25% more income than needed to cover debt. Most DSCR lenders require at least 1.0; 1.25+ gets the best terms.
DSCR loans are specifically designed for investment properties. Unlike traditional mortgages that rely on your personal income and DTI ratio, DSCR loans qualify you based on the property's projected income. This means investors can scale their portfolios without being limited by personal income -- a critical advantage for self-employed borrowers, entrepreneurs, or anyone whose tax returns do not reflect their true cash flow capacity.
AirROI computes DSCR automatically from real market data. By analyzing 50 comparable properties in your target market, the calculator derives Net Operating Income from actual STR performance data -- not generic national averages. AirROI shows all 50 comparable properties free, with no account.
DSCR loans are non-QM products, which means each lender sets their own bar. Across the dozen-plus lenders most active in STR financing in 2026, the qualifying envelope has converged on the numbers below.
| Requirement | Standard DSCR (≤ $1.5M) | Jumbo DSCR (> $1.5M) |
|---|---|---|
| Minimum DSCR | 1.0 (1.10-1.15 for STR programs) | 1.15 - 1.25 |
| Minimum FICO | 620 (680+ for best pricing) | 680 (720+ for best pricing) |
| Maximum LTV | 80% purchase / 75% cash-out | 75% purchase / 70% cash-out |
| Cash Reserves | 3 - 6 months PITIA | 6 - 12 months PITIA |
| Loan Amount | $100K - $1.5M | $1.5M - $4M (in-house), $20M case-by-case |
| Vesting | Personal or LLC (with personal guarantee) | Personal or LLC (with personal guarantee) |
| Income Documentation | STR booking history OR third-party projection (AirROI/AirDNA) OR Form 1007 | Same — typically requires 12 months actuals if available |
| Prepayment Penalty | 5-4-3-2-1 stepdown standard | 5-4-3-2-1 or 3-2-1; longer terms common |
| Closing Timeline | 21-30 days | 30-45 days |

The difference between a DSCR of 1.24 and 1.50 can save you $15,000-$40,000 in upfront down payment costs. Here is where each tier falls on the lender approval spectrum.
Property does not cover debt payments. Most lenders will decline the loan. Consider a larger down payment or a different property.
Approval requires compensating factors (25-30% down payment, 700+ FICO, 6+ months reserves). Expect a rate premium of 0.5-0.75% over standard pricing. STR-specific programs often impose a 1.10-1.15 floor here.
Most DSCR lenders approve at standard pricing with 20-25% down. This is the baseline tier for STR investment financing — neither premium nor penalized.
Qualifies for the lender's best pricing — typically 0.25-0.50% below standard rates with relaxed reserve requirements. Down payment minimum stays at 20% (75-80% LTV is the cap for STR DSCR regardless of coverage strength).
AirROI's calculator shows you exactly where your property falls on this spectrum, using revenue projections from 50 real comparable properties in your target market.
DSCR lenders accept three documentation pathways for short-term rental income. Knowing which one your lender uses — and the haircut they apply — determines whether your projected DSCR matches the number that lands on the underwriter's desk.
Booking history from the property's PMS or Airbnb host dashboard. Preferred by every lender when available — no haircut applied. Requires the property to have been operating as an STR for the full prior year.
Revenue estimates from AirROI, AirDNA, or Rabbu. Lenders apply a 10-25% haircut to buffer vacancy and seasonality risk. AirROI's projection — with the underlying 50 comparable Airbnb listing IDs visible — is the format underwriters review fastest.
The appraiser's long-term-rental comparable analysis. Used as a conservative fallback when the property is being converted from LTR or has no STR history. Almost always the lowest of the three numbers.
When you submit a third-party revenue projection, lenders almost always apply a 10-25% haircut before computing DSCR. A property AirROI projects at $90,000 may be underwritten at $72,000. The haircut is non-negotiable on most programs and varies by lender risk appetite — Visio and Kiavi typically apply 10-15%, while STR-conservative lenders go to 25%. Using the calculator's manual revenue override to model a haircut scenario before applying tells you whether your deal still pencils when the underwriter trims the projection.
For investors with multiple properties or self-employed income, DSCR loans remove the personal income bottleneck. AirROI provides the property-level revenue data lenders need to underwrite DSCR loans.
| Factor | DSCR Loan | Traditional Mortgage |
|---|---|---|
| Qualification Basis | Property income (NOI) | Personal income (DTI ratio) |
| Income Documentation | Property revenue projections | W-2s, tax returns, pay stubs |
| Portfolio Scaling | Unlimited (property-based) | Limited by personal DTI (typically 4-10 properties) |
| Typical Down Payment | 20-25% (25-30% for STR-specific programs) | 15-25% |
| Interest Rates (April 2026) | 6.5-8.75% for STR (0.75-2.25% premium over conventional) | 6.0-7.0% (Fannie/Freddie investment property) |
| Loan Limits | Up to $4M in-house, $20M case-by-case (non-QM, no GSE cap) | $832,750 baseline / $1,249,125 high-cost (2026) |
| Best For | Investors scaling beyond 4 properties, self-employed | First or second investment property |
| Speed to Close | 21-30 days (no personal income docs) | 45-60 days (full underwriting) |
| Title / Vesting | Personal or LLC (with personal guarantee) | Personal name only |
The same investor can land in three different lender tiers depending on price point, market, and capital stack. Each scenario uses PITIA-correct math (P&I + Taxes + Insurance + HOA) and shows both formulas: Investor DSCR (NOI ÷ Annual Debt Service) and Lender DSCR (Gross ÷ PITIA), since the gap between them is often what tips approval.

DSCR is fully under your control before underwriting. Three levers move it. The biggest gains come from understanding which lever has the most slack on your specific deal — not from optimizing all three equally.
Each $1 of additional annual revenue increases DSCR more than $1 of expense reduction (because revenue lifts both the numerator and lowers the relative weight of fixed costs). Use AirROI's comparable data to see what the top decile in your market earns — then back-solve: better photos, faster guest response, dynamic pricing, premium amenities (hot tub, EV charging, fast Wi-Fi).
Match top-decile ADR within your market
Lift occupancy 5-10% via dynamic pricing
Add 2-3 high-margin amenities
The single largest controllable expense is property management (typically 20-25% of revenue). Self-managing instead of using a full-service PM is the most powerful single move available — it can lift NOI by $10K-$25K annually on a typical STR. After PM, the remaining levers are insurance shopping, cleaning negotiation, and utility plan optimization.
Self-manage to save 20-25% of revenue
Re-shop insurance every 18-24 months
Bundle cleaning across multiple properties
A larger down payment lowers debt service directly. Going from 20% to 25% down on a $400K property at 7.5% drops monthly P&I by ~$140 and lifts Investor DSCR by ~0.10. The marginal gain narrows above 30% — most STR deals hit the sweet spot at 25%, where you also unlock better-pricing tiers without locking up excess capital.
25% down is the sweet spot for STR
Each 5% bump = ~0.10 DSCR lift
Above 30% rarely justifies the capital cost
Even with strong DSCR, applications fail for predictable reasons. Address these before submitting to avoid wasted application fees and credit pulls.
Sub-1.0 means the property doesn't cover its own debt. A handful of lenders accept it with 6-12 months reserves and 30%+ down, but most decline. If your DSCR is 0.85-0.99, your fastest path is increasing the down payment to 30-35% to lift coverage above 1.0.
Lenders will accept lower FICO OR lower DSCR — not both. A 620 FICO is workable at 1.40+ DSCR; a 1.05 DSCR is workable at 720+ FICO. The intersection of marginal credit and marginal coverage is where deals get declined.
Lenders flag properties in cities with active STR enforcement or pending bans (Los Angeles, San Francisco, NYC, Honolulu, parts of Hawaii, parts of Austin). Some lenders won't underwrite STR income in these markets at all, defaulting to Form 1007 LTR rents — which usually drops DSCR below 1.0.
Properties in buildings with hotel-like services (front desk, daily housekeeping, pooled rental programs) are often classified as condotels by appraisers, which most DSCR programs exclude. Verify the building's classification with the lender before contracting.
In permit-required markets (Nashville, New Orleans, much of Florida coastal), lenders verify the STR permit during underwriting. An expired or missing permit kills the deal even if DSCR is strong, because the income source is technically illegal.
Even with strong DSCR, lenders require 3-6 months PITIA in liquid reserves. Reserves stack across financed properties — an investor with 5 properties needs 15-30 months total. Listing all sources up front (checking, savings, retirement minus penalty, securities at 70% face value) prevents post-application surprises.
The hard floor at most STR-friendly DSCR lenders is 1.0 — your property income must at least equal annual debt service (PITIA: principal, interest, taxes, insurance, HOA). However, 1.25 is the threshold for best pricing and standard 20-25% down terms. STR-specific programs often require a 1.10-1.15 minimum because of seasonality and vacancy risk. A DSCR above 1.5 unlocks the most favorable terms — lower rates and faster underwriting — though sub-80% LTV remains the cap for STR (no STR DSCR lender offers 90% LTV regardless of DSCR strength).
As of April 2026, DSCR loan rates run 6.12-7.99% for well-qualified standard DSCR borrowers. STR-specific programs add a 0.25-0.75 point premium to compensate for vacancy and seasonality risk, putting actual STR DSCR rates in the 6.5-8.75% range. The total premium versus a conventional investment-property mortgage is roughly 0.75-2.25 points. A 740+ FICO with 1.50+ DSCR and 25% down typically lands at the bottom of that range; a 680 FICO at 1.10 DSCR with 20% down lands near the top.
AirROI computes DSCR two ways, side by side: Investor DSCR (NOI ÷ Annual Debt Service, using P&I only) for true cash-flow coverage, and Lender DSCR (Gross Annual Rent ÷ Annual PITIA) — the formula 1-4 unit DSCR lenders actually underwrite on. Both numbers are derived from 50 comparable properties in your market with verifiable Airbnb listing IDs, plus your inputted purchase price, down payment, rate, taxes, insurance, and HOA. Every input is transparent and adjustable, which is the same documentation level a DSCR underwriter wants to see.
Yes — DSCR lenders accept three documentation pathways for STR income: (1) 12 months of actual booking history from the property's PMS or Airbnb dashboard, (2) third-party revenue projections from tools like AirROI or AirDNA, and (3) the appraiser's Form 1007 long-term rent schedule as a conservative fallback. Lenders typically apply a 10-25% haircut to projection-based income to buffer against vacancy and seasonality, then take the higher of the three sources. AirROI's projection — with the underlying 50 comparable listings visible — provides the reviewer-friendly documentation underwriters prefer.
Most DSCR lenders require a 620 FICO minimum, though 660-680 is the practical floor for competitive pricing. The tier breaks: 620-679 (qualifies but premium pricing), 680-699 (standard pricing), 700-739 (good pricing, ~0.25% better), 740+ (best pricing, another 0.25-0.50% off). Cash reserves of 3-6 months PITIA are standard; jumbo loans (>$1.5M) require 6-12 months. Sub-1.0 DSCR exceptions need 6-12 months. Reserves stack across financed properties — a 6-property portfolio needs liquid reserves for all six PITIA payments.
DSCR loans typically close in 21-30 days, versus 45-60 days for conventional investment-property mortgages. The compression comes from skipping personal income verification — no W-2s, tax returns, or DTI calculations. The bottleneck shifts to the appraisal (Form 1007 rent schedule for STR or Form 1004 for conventional) and the lender's reserves verification. Investors competing on time-sensitive deals often choose DSCR specifically for this speed advantage.
DSCR (Debt Service Coverage Ratio) qualifies you based on the property's projected income. DTI (Debt-to-Income Ratio) qualifies you based on your personal income and debts. DSCR loans suit investors scaling beyond 4-10 properties, self-employed borrowers, or anyone whose tax returns understate true cash-flow capacity. Fannie Mae allows up to 10 financed properties under DTI rules, but properties 5-10 require 25% down, 6 months reserves on every property, and 720+ FICO — making DSCR the practical pathway after the fourth or fifth property.
Yes. DSCR is one of the most common vehicles for the refinance leg of BRRRR (Buy, Rehab, Rent, Refinance, Repeat). Cash-out DSCR refis typically cap at 75% LTV (vs 80% for purchase), require a seasoning period of 6-12 months on the title, and use the post-rehab appraisal value. Watch for prepayment penalties — most DSCR loans carry a 5-4-3-2-1 stepdown PPP (5% of balance in year 1, declining annually). Accepting a PPP usually buys down your rate by 0.25-0.50%, but penalizes early refi or sale.
Three levers: (1) Increase revenue — optimize pricing, improve listing quality, add high-margin amenities. AirROI's comparable data shows what the top decile in your market earns, your roadmap to a higher DSCR. (2) Reduce operating expenses — self-manage to save 20-25% (the typical PM fee), shop insurance, negotiate cleaning. (3) Increase down payment — a larger down payment lowers debt service directly. The marginal gain narrows above 30% down, so the sweet spot for most STR deals is 25%. Use AirROI's worksheet to model the trade-off across all three levers in real time.
