The Quick Read: Match the loan to the income the lender will actually count, which means you pick the strategy the property can prove, confirm that short-term use is legal, and check that the coverage ratio still clears the program floor under a cautious version of the numbers. Run the same property through a long-term rent test and a short-term rental test, then take the loan path that holds up when the optimistic assumptions come off.
- Leverage differs by strategy. On a purchase, short-term rental (STR) collateral tops out at 75% LTV on the strongest files, while standard long-term rentals (LTR) typically land at 75%-80%, subject to lender guidelines.
- Cash-out is lower on STRs. Cash-out tops out around 70% LTV on short-term-rental collateral and around 75% on standard long-term rentals.
- STR files ask more of the borrower. Expect a 640+ credit score and about 12 months of landlord or host experience.
- Coverage floors are program-specific. 1.00 is where select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted.
- Clearing the floor is not profit. The coverage ratio ignores repairs, vacancy, management, and utilities.
Key Terms Defined
DSCR (debt service coverage ratio) is the property’s monthly rent divided by its full monthly housing payment. A result above 1.00 means the rent covers the payment on paper.
PITIA stands for principal, interest, taxes, insurance, and association dues. It is the full payment that goes under the line in the DSCR calculation.
LTV (loan-to-value) is the loan amount as a percentage of the property’s value. A 75% LTV means you bring the other 25%. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
LTR (long-term rental) is a property leased to a tenant under a signed lease, usually for a year or more.
STR (short-term rental) is a property booked by the night or week, usually through a platform. The income comes from bookings, not a lease.
Mid-term rental is a furnished unit rented for stays of roughly a month or longer. Lenders treat it differently from program to program.
Haircut is the reduction a lender applies to projected rental income before it divides by the payment. It exists because gross booking revenue overstates what an owner keeps.
Seasoning is the waiting period a lender wants between buying a property and refinancing it. About six months is the common expectation on cash-out files.
Why Does the Lender Care Which One You Pick?
A lease is a signed promise to pay. A booking calendar is a forecast. That single difference drives almost everything about how the two financing paths differ.
With a long-term rental, the lender counts either the lease or the appraiser’s market rent. The number is stable and easy to document. With a short-term rental, income moves with seasons, reviews, local events, and how the owner manages the listing. Lenders respond by asking for more history, applying a haircut, and sometimes setting lower leverage.
The core test stays the same either way. The lender divides qualifying monthly income by the full housing payment and checks the result against the program’s floor. Only the income figure changes. So the real question is never which strategy is better. It is which income figure the lender will count, and whether that figure still works when you stress it.
How Does Underwriting Treat Each Path, Step by Step?
Underwriting a dual-use property follows a fixed order, and the first step has nothing to do with income.
Step 1: Legal use. Short-term income only counts if short-term use is lawful at the address. 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. A property with a great projection and a rental ban has no short-term income for underwriting purposes.
Step 2: Income evidence. What the lender asks for depends on the strategy:
- Long-term rental: a signed lease, or the appraiser’s market-rent opinion. For a single-family home that opinion comes on Form 1007. For two to four units it comes on Form 1025.
- Seasoned short-term rental: trailing platform statements or property-management reports showing what the property actually earned.
- Short-term rental with no history: a third-party projection or an STR-specific appraisal. This applies to a new purchase or a property switching from a long-term tenant.
Step 3: Understand the projection. Projections are models. AirDNA’s Rentalizer estimates revenue, nightly rate, and occupancy from comparable nearby listings. It searches within a 10-mile radius and weights comps by proximity and by bedroom, bathroom, and guest-count match.
Step 4: Know what the number includes. AirDNA calculates revenue as nightly rates plus cleaning fees, minus service fees and discounts. Other host costs are not in it. The result is gross revenue, not net income, which is why lenders apply their own haircut. How big that haircut is varies by lender.
Step 5: Divide and compare. The lender divides qualifying income by PITIA and checks the ratio against the program floor. On the programs Lendmire places short-term rentals with, that floor is 1.00 on purchases and refinances.
Step 6: Check the borrower. Credit score, reserves, and experience still apply. Reserves vary by lender, leverage, loan size, and transaction type. They commonly run around six months of PITIA, though conservative rate-and-term files at modest leverage under $1,500,000 can see them waived, and larger loans typically step up to about nine months.
The STR Path and the LTR Path Side by Side
These are typical ranges, not promises, and every file is underwritten individually.
| Factor | LTR path | STR path |
|---|---|---|
| Income evidence | Lease or market rent | History or projection |
| Appraisal rent opinion | Form 1007 / Form 1025 | STR-specific review |
| Purchase LTV | Typically 75%-80% | Up to 75% |
| Cash-out LTV | Around 75% | Up to 70% |
| Credit score | Most want ~660 | 640 minimum |
| Experience | Not usually the focus | About 12 months expected |
Credit works differently on the LTR side. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Select high-leverage purchase programs reach 85% LTV with roughly a 700+ score, but that is a long-term-rental feature.
A bigger down payment helps in one specific way. It lowers the payment, which can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests, enough equity and enough rental coverage.
Run the Same Property Both Ways
Picture a three-bedroom house in a market where it could rent to a family or to vacationers. The inputs below are modeled assumptions, not market data.
Start with the long-term test. Say the appraiser’s market rent produces a coverage ratio of about 0.92x. That sits below 1.00.
Now run the short-term test. Say the projected booking revenue, after the lender’s haircut, produces about 1.20x. On paper the short-term path clears 1.00 and the long-term path does not.
Before you pick, stress the short-term number. Cut the adjusted income by another 20%, which is a reasonable downside for a soft season or an optimistic model, and coverage falls to about 0.96x. The cushion is gone.
Here is how the options compare:
- Take the STR path. The file clears the floor, but a thin cushion means the strategy has to deliver. You also need legal use confirmed and the experience the program expects.
- Take the LTR path at lower coverage. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Qualification is subject to lender guidelines, credit approval, and property review.
- Put in more equity. A larger down payment lowers the payment and can lift the ratio on either path, within the leverage caps.
This is a genuine judgment call. The STR path produces the stronger number, while the LTR path produces the more defensible one. If the property only works at the optimistic short-term figure, the loan is betting on the strategy. Many investors prefer a loan they can carry if the Airbnb plan underperforms.
One more reminder. A ratio above 1.00 is not positive cash flow. Repairs, vacancy, management fees, utilities, and capital expenses all sit outside the DSCR calculation. Short-term rentals often carry operating costs far above long-term rentals, so the lender’s haircut and your real expense load are different numbers.
Where the General Rule Breaks
The step-by-step above is the normal case. These are the situations that bend it.
The lender may not count STR income at all. Some programs underwrite only the appraiser’s market rent. If you plan a short-term strategy, ask which income figure the program will actually use before you pay for an appraisal.
AirDNA is a model, not a ledger. Magicbnb’s commentary says AirDNA infers occupancy from calendar data and cannot always tell a real booking from a night the host blocked. VaultSTR’s commentary says Rentalizer can run optimistic. Treat the projection as a starting point and haircut it yourself.
Seasonality gets averaged. Underwriting looks at a full year. A beach house with huge summer months and a dead winter gets judged on the annual average, not the peak.
Unit count and property type matter. Some programs accept short-term income on smaller properties and not on larger ones. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs, whatever the income potential.
A rural designation on the appraisal can change terms. Lenders unfamiliar with short-term rentals may react to it with lower leverage or a decline.
Vacant purchases can conflict with the strategy. Some lenders will finance a vacant property but want a lease in place. A short-term rental has no lease by nature, so confirm how the program treats a vacant STR purchase.
Mid-term rentals sit in between. Furnished stays of 30 days or more often have steadier occupancy than nightly stays.
Tax class and loan class are separate tests. A lender reviews the property’s rental income, not your tax classification. The IRS looks at average guest stay in Publication 925, and tax treatment varies, so consult a qualified tax professional.
A Decision Process You Can Use
Work through this order, and stop wherever the answer is no.
1. Confirm legal short-term use. Check local rules and HOA or condo documents first.
2. Collect both rent figures. Get the market rent and a short-term projection or booking history.
3. Match income to evidence. If you have 12 months of history, use it. If not, expect the lender to lean on a projection or appraisal.
4. Ask which income the program counts. Do this before you apply, not after.
5. Run the downside. Haircut the short-term number and see where coverage lands.
6. Check the long-term fallback. If the property cannot survive as a rental on market rent, the loan carries strategy risk.
7. Compare the loan fit. Weigh leverage, credit, reserves, and the pricing difference between the two programs.
How the answer shifts by situation:
- New buyer with no hosting history: the STR path may be harder to qualify for, since programs expect about 12 months of experience. The LTR path is the simpler route in.
- Existing owner with a seasoned STR: trailing statements are the strongest evidence you can bring, and the STR path usually fits.
- Thin reserves: the loan with the lower reserve demand and larger cushion is safer, which often means long-term underwriting.
- Portfolio scaler: DSCR loans do not run into the property-count caps that apply to conventional loans, so the right path depends on each property’s own numbers.
Can You Switch Strategies After Closing?
Yes, but the loan was underwritten on one story. If you close on long-term rent and later convert to short-term use, the loan stays in place. You simply lack the history to refinance on STR income until you build it.
The reverse also works. A property financed as an STR can go back to long-term tenants, as long as local rules and HOA documents allow. The catch is that the refinance underwriting would then follow whichever income you can document at that time.
Read the loan terms for prepayment structure before you sign. A prepayment penalty is a fee for paying off the loan within a set period, and it can make a strategy-driven refinance more expensive. Lendmire’s piece How to Time an STR Cash-Out Refi When You’re Past Conventional Loan Limits covers how seasoning and hosting history shape that move.
Mistakes That Cost Investors
- Annualizing the best months. Peak-season revenue stretched across twelve months overstates what underwriting will count.
- Treating the projection as income. It is a gross-revenue estimate built from comps.
- Skipping the legal check. Strong numbers do not help if the property cannot legally host short stays.
- Assuming every lender counts Airbnb income. Ask before you commit to an appraisal.
- Confusing coverage with profit. A ratio just over 1.00 can still lose money after real expenses.
- Ignoring the fallback. A property that only works as an STR carries all its risk in one assumption.

Frequently Asked Questions
Which is easier to qualify for, an STR or an LTR?
Usually the long-term path, because the income evidence is a lease or market rent and the experience requirements are lighter. Short-term rental programs typically expect a 640+ credit score and about 12 months of landlord or host experience, with lower leverage on refinances. Qualification is subject to lender guidelines.
Can a property qualify on STR income if long-term rent falls short?
Sometimes, if the program counts short-term income and the adjusted figure clears the floor. The lender may apply a haircut to projected revenue, so the cushion shrinks. If the property misses 1.00 on long-term rent, coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted.
Does strong Airbnb data guarantee approval?
No. Legal use, the lender’s haircut, the borrower’s credit and experience, and the property type all have to line up. A projection is an estimate of gross revenue, not a commitment from any lender.
What happens if short-term rules change after I close?
The loan does not disappear, but the strategy may. A property that still works on long-term rent gives you a way to pivot.
Is a mid-term rental financed like an STR or an LTR?
It depends on the program and on how the lender documents the income. Furnished stays of a month or longer often have steadier occupancy, so some lenders treat them closer to a lease-backed rental. Ask before relying on that treatment.
