The Quick Read: The job is to test, before you make an offer, whether an area’s occupancy, nightly pricing, seasonality, and local legality can support a rental income figure that a lender will accept and that still covers the full housing payment with room to spare. Lenders look at the property’s income, not yours, so the market you pick sets the number they work with.
- Short-term rental (STR) income is a projection or a history, not a lease, so lenders review it more closely than long-term rent.
- Most files count one of three income routes: trailing platform history, a third-party projection, or the appraiser’s long-term rent schedule.
- Plan on the number after a lender haircut, not the headline estimate.
- Coverage measures rent against the payment only, so a file can clear it and still lose money.
- STR purchases in the network typically reach up to 75% LTV, with a 640 credit score minimum and a 1.00 coverage floor, subject to lender guidelines.
What Does It Mean to Underwrite an STR Market for DSCR?
It means judging a whole market the way a lender will judge one property. You check whether demand is deep, whether the income is steady enough to trust, and whether the property can legally operate as a short-term rental.

As of Oct 15, 2026 · General Freddie Mac market benchmark, not a Lendmire loan offer. Nightly rate, occupancy, taxes, and insurance are editable estimates. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
A DSCR loan qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The ratio is monthly income divided by monthly PITIA: principal, interest, taxes, insurance, and any HOA dues. On a long-term rental, the income is a signed lease or an appraiser’s rent estimate. On an STR, it is an estimate of what guests will pay. That estimate can swing with the season, the comp set, and the platform data behind it.
That difference drives everything below. The complete DSCR loans guide covers the basics of how the ratio works. This article covers the pre-offer work that is specific to STRs.
Key Terms Defined
ADR (average daily rate): the average nightly price a property earns on nights that are actually booked.
Occupancy: the share of available nights that are booked.
RevPAR: revenue per available night, which equals occupancy multiplied by ADR.
Haircut: the discount a lender applies to projected income before dividing by the payment.
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly housing obligation.
Comp set: the group of similar STRs used to estimate a property’s income.
How Do Lenders Count STR Income?
Across the wholesale network, most programs use one of three routes. The route decides which documents you need and where the risk sits.
| Income route | When it applies | Main risk |
|---|---|---|
| Trailing platform history | Property already operates as an STR | Past income may not repeat |
| Third-party projection | Purchase with no history | Estimate can overstate income |
| Appraiser long-term rent | Fallback or blended | Often understates vacation markets |
For the history route, expect platform payout statements and proof the STR use is legal. For the projection route, expect a market report that matches your bedrooms, baths, and guest count. For the appraiser route, the appraiser completes a rent schedule (Form 1007) or an operating income statement (Form 1025). Programs differ on how they haircut each route, and the strictest overlays discount projections the hardest. That spread is why the lender’s number is rarely your operating number.
What Do the Lending Guardrails Look Like?
STR files carry tighter terms than long-term rentals. Typical ranges across select lenders in the network, subject to lender guidelines:
- Purchases run up to 75% LTV on the strongest files, while standard long-term rentals on a purchase reach 75% to 80%.
- Refinances run around 70% LTV, and an STR cash-out is also capped at 70%, while a standard rental cash-out tops out near 75%.
- A credit score of 640 or higher is typical, with stronger scores helping pricing and leverage.
- Programs usually expect about 12 months of landlord or host experience.
- Coverage starts at 1.00 on STR purchases, and refinances also start at 1.00.
- Standard loan sizes run up to $3,000,000.
- Reserves vary by lender, leverage, and loan size, and commonly sit around six months of PITIA.
A larger down payment lowers the payment and can lift coverage. It does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Step 1: Screen the Market Before You Pick a Property
Start with the market, because a weak market caps what any property can show. Score five things before you look at listings.
Demand depth. Look at trailing-twelve-month occupancy, ADR, and RevPAR for the market and for your property tier. A market with a few strong months and many empty ones scores worse than one with steady mid-level demand.
Seasonality. BiggerPockets recommends building a month-by-month table of ADR, occupancy, days in the month, and occupied days. The table shows your slow-season troughs and how much cash you need to carry the property through them. Lenders may average income across the year, but your bank account lives month to month.
Supply trend. Count how many new STRs are entering the market. Rising supply can push occupancy and ADR down just as you buy.
Market type. Destination markets, drive-to markets, urban markets, and event-driven markets behave differently. Event-driven income can look strong in a short window and thin the rest of the year.
Legality. This is a gate, not a score. BiggerPockets lists the items to confirm: night caps, zone limits, licensing, and outright bans in residential areas. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Step 2: Build the Comp Set Like a Skeptic
The comp set is where most overstated projections start. Third-party tools pull comparable STRs and weight them by similarity, but the pool may include stronger listings than yours.
Filter by bedroom count, bathroom count, and guest capacity first. Then compare amenities such as a hot tub, a view, or a pool. Compare condition and review quality too. Distance matters less than similarity, since two listings a few miles apart can perform very differently.
Exclude these from your set:
- Listings with far more bedrooms than yours.
- Properties with amenities yours lacks.
- Listings with only a few months of data.
- Luxury outliers that skew the average.
Then pull income at more than one level. A median-level comp case is your base. A lower-percentile case is your stress case. Cross-check both against actual listings, not just the headline estimate.
Step 3: Reconcile Three Revenue Figures
You will usually end up with three numbers that disagree. Your job is to decide which one to plan around.
| Figure | What it reflects | How to use it |
|---|---|---|
| Platform or data-vendor projection | Comp-based market estimate | Upper bound, before haircut |
| Trailing history (if any) | What this property earned | Strongest evidence available |
| Appraiser long-term rent | Annual-lease value | Floor and fallback |
Two cautions apply to the projection. Data-vendor revenue figures typically include cleaning fees but not taxes or platform service fees. That makes them a gross picture, not host take-home. They also cannot see everything, such as direct bookings or last-minute discounts.
A sound rule: plan on the lower of the haircut projection and the history. Treat the appraiser’s long-term rent as the downside anchor.
Step 4: Build the Revenue, Expense, and Payment Model
Revenue is simple. BiggerPockets gives the formula as ADR multiplied by occupancy, multiplied by 365 and divided by 12 for a monthly figure. Use the month-by-month build to catch seasonal gaps the annual average hides.
Next, load the payment. Coverage divides the income figure by the full PITIA, including taxes, insurance, and any HOA dues. Use real quotes for insurance and taxes, since an STR policy can differ from a standard landlord policy.
Then build your own expense line, which the lender’s ratio ignores. Real Estate Investor Toolkit walks through a month-by-month build and treats regulation as a real risk. Your list should include:
- Utilities and internet.
- Cleaning and turnover.
- Platform and management fees.
- Supplies and furnishing replacement.
- Repairs and a capex reserve.
Worked Example: One Hypothetical Property, Three Cases
These inputs are modeled assumptions, not market data. Picture a three-bedroom property in a mid-tier vacation market. Every figure is a coverage ratio.
- Data-vendor projection before haircut: about 1.45x.
- Same projection after a lender haircut: about 1.30x.
- Conservative-percentile case, haircut applied: about 1.15x.
- Appraiser long-term rent schedule: about 0.85x.
The first three clear 1.00 and the fourth does not. If the lender relied on the long-term route alone, this file would sit below 1.00. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted, while 1.00 is where many select programs start. Which path applies depends on lender guidelines, credit, reserves, and property review.
What Happens When Occupancy and Pricing Slip?
Take the 1.30x base case at 60% occupancy and test it. Coverage moves in direct proportion to occupancy and nightly price, so the grid is easy to build for any deal.
| Nightly price vs base | 60% occupancy | 50% occupancy | 45% occupancy |
|---|---|---|---|
| Base | 1.30x | 1.08x | 0.98x |
| 10% lower | 1.17x | 0.98x | 0.88x |
| 20% lower | 1.04x | 0.87x | 0.78x |
Read the grid for cushion. A deal that falls below 1.00 after a 10-point occupancy drop has thin margin. One practitioner guide treats annual market occupancy under 45% as a red flag. That is an opinion, not a rule, but the grid shows why: at 45% the base case already sits just under 1.00.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Where Does the General Rule Break?
The steps above fit most files. These edge cases change them.
No history on a new purchase. The projection route becomes your only income evidence, so the comp set carries more weight. The 12-month host experience expectation also matters here, since programs look at the borrower’s record as well as the property.
Seasonal markets. Never annualize a peak-season snapshot. A property that earns most of its income in four months can look excellent on a three-month window and weak over a full year.
Blended buildings. Some multi-unit properties have units on leases and units rented nightly. Those files are usually reviewed on a blended rent roll.
Thin-data markets. Rural or low-volume areas often lack enough comps for a reliable projection, and programs may pass on them.
Property type. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs, whatever the rental income.
Refinance exits. If your plan is to buy, stabilize, and refinance, test the exit before the purchase. Lendmire’s piece How to Underwrite the DSCR Refinance Before a BRRRR Hard Money Buy covers that logic.
When Should You Walk Away?
Set kill criteria before you spend on inspection and appraisal. Walk away, or change the deal, when any of these holds:
- STR use is banned, capped out, or unclear at the specific address.
- Your conservative case falls below 1.00 and the base case clears it by only a thin margin.
- The comp set only works when you include stronger properties.
- Slow-season months would drain more reserves than you hold.
- The lender’s income method cannot be confirmed before you write an offer.
If you are reaching for a sub-1.00 structure because no property in the market clears 1.00, that is a signal about the market. The better move may be a different submarket.
Does Clearing the Ratio Mean the Deal Makes Money?
No. Coverage compares income to PITIA only. Utilities, cleaning, platform fees, furnishing, repairs, vacancy, and capex all sit outside the calculation, so a file can pass underwriting and still lose money.
BiggerPockets stresses adding regular business expenses to any STR analysis. Treat the lender’s ratio as a minimum test and your own after-expense model as the real one. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Your Pre-Offer Sequence
1. Screen the market on demand, seasonality, supply, market type, and legality.
2. Confirm STR use is allowed at the specific address, including any HOA rules.
3. Build a filtered comp set and pull base and conservative cases.
4. Reconcile the projection, any history, and the appraiser’s long-term rent.
5. Load the full PITIA, including real insurance and tax quotes.
6. Run the occupancy and nightly-price grid and size slow-season reserves.
7. Confirm with the lender how it counts STR income and which haircut applies, before you write an offer.

Frequently Asked Questions
Which income will a lender use on an STR purchase with no history?
Usually a third-party market projection, discounted by a haircut, with the appraiser’s long-term rent schedule as a fallback. Programs differ on the haircut size and on which route they prefer. Ask the lender to confirm the method before you make an offer.
Is the projection from a data tool the number the lender will use?
Usually not. Lenders commonly discount projections because the figures are estimates, so plan on the lower, haircut number. Check the tool’s property details too, since a wrong bedroom count or guest capacity inflates the result.
Can I buy an STR if I have never hosted?
It is harder. Programs in the network typically expect about 12 months of landlord or host experience, along with a 640 or higher credit score. A borrower without that record may need a different structure or a lender with different overlays, subject to lender guidelines.
What leverage can an STR purchase reach?
Typically up to 75% LTV on the strongest files, with refinances and STR cash-outs around 70%. Standard long-term rentals reach 75% to 80% on a purchase, and select high-leverage programs go higher for strong credit. Reserves, credit, and property review still apply.
What if the property clears 1.00 only on STR income?
That can work, but it deserves a closer look. Run the conservative case and the appraiser’s long-term rent. If only the optimistic projection clears 1.00, the margin for error is thin.
