The Quick Read: No single number applies, because each lender’s grid sets the cut and the grid reads coverage, credit, loan size, and transaction type together. On short-term-rental files across Lendmire’s wholesale network, purchase leverage tops out at 75% LTV and refinance or cash-out tops out around 70%, and those ceilings assume coverage of at least 1.00. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
- The cut comes from a grid, not a formula. Two lenders can look at the same Airbnb and land on different leverage.
- Most standard programs start at a 1.00 coverage floor. Below that, a separate select-lender path takes over.
- Lost LTV means more cash down on a purchase and a smaller check on a cash-out.
- STR income is usually haircut before the ratio runs, so a property that looks fine on raw platform revenue can land under 1.00.
- A smaller loan can raise the ratio, so the leverage cut and the coverage gap partly fix each other.
Here is how the process works on a real file, where it breaks, and what an investor can do about it.

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.
Key Terms Defined
DSCR (debt service coverage ratio): Qualifying rental income divided by the full monthly housing obligation.
PITIA: Principal, interest, taxes, insurance, and association dues. This is the denominator in the ratio.
LTV (loan-to-value): The loan amount divided by the appraised value. Down payment and LTV mirror each other.
STR haircut: A lender-specific reduction applied to gross short-term-rental income before the ratio is calculated.
Grid (or matrix): The lender’s table that sets maximum LTV by coverage band, credit score, loan size, transaction, and property type.
No-ratio loan: A structure where the ratio is not the qualifier. It is available only through select lenders, generally for borrowers who already own a primary residence.
Why Does Coverage Drive the Leverage Cap?
A ratio under 1.00 means the property’s income does not cover its full monthly obligation. The borrower funds the gap out of pocket. A lender that sees that gap wants more equity at stake, and a bigger equity cushion also protects the lender if the loan goes bad, since foreclosure is the main recourse on default. That is why the cut exists. It is risk logic, not a penalty.
That logic also explains why the size of the cut varies. A lender that tolerates a thin shortfall may trim leverage a little. A lender that sees a wide shortfall, or a thinner credit file, trims more.
How Underwriting Handles an Airbnb File, Step by Step
On a typical STR file, the sequence runs like this.
1. Income is established. The figure comes from 12 months of platform history, a market projection from a data vendor, or a long-term rent schedule used as a fallback. Because STR income swings, lenders look harder at it than at a standard lease.
2. The appraisal supplies value and rent. Appraisers use rent-schedule forms, and the agency forms give a useful reference point. Form 1007 is the Single-Family Comparable Rent Schedule and Form 1025 is the Small Residential Income Property Appraisal Report. DSCR loans are not agency products, so those forms only show what appraisers typically deliver. For contrast, the agency’s own guide requires the 1007 on one-unit investment properties when rental income is used to qualify. Ask which rent form your lender orders.
3. The haircut is applied. The lender reduces gross STR income by its own factor. That factor differs by lender, which is why two lenders can show two different ratios for the same house.
4. The ratio is computed. Qualifying income divided by PITIA. It falls if the appraiser’s rent comes in low, if insurance or taxes rise, or if the haircut is heavier than expected.
5. The grid is read. The matrix combines coverage band, credit score, loan amount, purchase versus refinance, and property type. The lowest applicable cap governs.
6. Value, not price, sets the loan. LTV runs on the appraised value. A low appraisal shrinks the loan even when the contract price is higher.
What Does the Cut Look Like Across the Network?
Across most programs Lendmire places files with, the STR ceilings are the starting point. These are typical ranges for the strongest files, subject to lender guidelines and full file review.
| Transaction | Typical STR ceiling | Coverage floor |
|---|---|---|
| Purchase | Up to 75% LTV | 1.00 |
| Refinance | Around 70% LTV | 1.00 |
| Cash-out | Up to 70% LTV | 1.00 |
STR files also typically expect a 640 or better credit score and about 12 months of hosting history. Loan sizes run up to $3,000,000 on standard programs.
Now the sub-1.00 question. Most standard programs start at 1.00. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. The adjustment is not a fixed number. Market surveys report cuts in the range of a few points up to about ten points of LTV from the top tier. Treat that as a market-wide observation, not a network promise. Within Lendmire’s network, the cut depends on the lender chosen, the coverage band, credit, and transaction type, and the right way to learn it is to ask for the grid before making an offer.
One more point on the 1.25 figure that appears in some general guidance. It is a commercial or conservative benchmark. Many DSCR programs start at 1.00, and stronger ratios open better pricing and leverage. Neither number is a rule for every file.
What the Lost LTV Means in Cash
On a purchase, each point of LTV you lose is a point more down. Run the numbers on a property priced at $500,000. At 75% LTV the down payment is 25%. If a below-1.00 path trims the ceiling by five points, the down payment moves to 30%. Cut ten points and it moves to 35%. Same house, same price, a bigger check at the table. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Cash-out works the other way. Lost LTV does not raise a down payment. It shrinks the proceeds. On an Airbnb with a cash-out ceiling near 70%, a five-point cut puts the ceiling near 65%, and the equity you can pull falls by the same five points of value. Investors who budgeted a specific amount of cash to fund the next purchase are the ones surprised here.
Rate-and-term refinance sits in between. No cash comes out, but a lower cap can mean the existing balance no longer fits, and the gap has to be paid in at the table.
Reserves compound the picture. They vary by lender, leverage, loan size, and transaction type, commonly around 6 months of PITIA. Select-lender paths below 1.00 often want more. Loans above $1,500,000 typically step up to about 9 months. Reserves documentation needs to be clean before the file goes in.
Three Ways an Airbnb File Lands Under 1.00
The cause matters, because the fix differs.
| Failure mode | What is wrong | Typical fix |
|---|---|---|
| Low income | Rent or history is thin | Build history, use a stronger projection |
| High costs | Taxes, insurance, dues are heavy | Smaller loan, shop insurance |
| Method understates | Haircut cuts a good property | Compare lenders’ haircut methods |
Low income is a property problem. High costs are a denominator problem. The third is a lender-method problem, and it is the one investors miss. Two lenders applying different haircuts to the same platform history can produce a swing wide enough to move a file across the 1.00 line. The property did not change. The yardstick did.
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 the General Rule Breaks
Slightly under 1.00 after the haircut. A file that looks strong on raw platform revenue can drop under 1.00 once the haircut applies. The haircut decides which side of the line it lands on. Underwrite with the haircut already in.
Seasonality. Lenders underwrite an averaged income figure, not the peak months. A beach house that earns most of its income in a few summer months is judged on the average.
Stacked caps. A property can hit another cap regardless of coverage. A condo or a 2-4 unit building may carry its own limit. The lowest applicable cap governs, so a strong ratio does not lift you past it.
Projected income versus history. A purchase with no history leans on a projection. A refinance with 12 months of hosting history can lean on actual records. The documentation path differs, and so can the ratio.
Lowering the loan to raise the ratio. A smaller loan lowers the payment, which raises coverage. Here is the catch: taxes and insurance do not shrink with the loan. The loan has to fall by more than the payment needs to fall. Still, the LTV cut and the coverage problem can partly cancel out.
Property types outside the programs. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs, at any coverage level.
Clearing 1.00 is not positive cash flow. The ratio compares rent to PITIA only. Cleaning, management, utilities, repairs, vacancy, and capex sit outside it. An Airbnb can clear 1.00 and still lose money.
Which Lever Fixes the Gap?
Think this one through before choosing. A bigger down payment lowers the payment and can lift the ratio, but it never erases the leverage cap, the credit floor, or the reserve rule. The strongest files clear both tests: enough equity and enough rental coverage.
| Lever | Helps | Trade-off |
|---|---|---|
| Larger down payment | Lowers payment, lifts ratio | Ties up more cash |
| Interest-only period | Lowers the payment line | Available through select lenders; balance doesn’t amortize |
| Extended term (40-year) | Lowers the payment line | Available through select lenders |
| Documented history | Replaces projection | Needs 12 months of hosting |
| Insurance re-shop | Cuts the denominator | Limited room on coastal or high-risk property |
| Different lender haircut | May raise qualifying income | Requires comparing grids |
An investor who modeled insurance low sometimes finds the quote lands well above the estimate. One investor reported quotes running 30 to 40 percent above what he had modeled, which pushed a couple of deals under 1.00. That is one person’s anecdote, not a market statistic, but the lesson holds. Get a real insurance quote before the file goes in.
Experience from the broker side: files with this profile usually go wrong on documentation before they go wrong on math. An insurance quote that is stale, a platform export that does not tie to the bank deposits, or an appraisal rent that disagrees with the projection each force a restart. Cleaner inputs mean fewer re-runs of the grid.
If Coverage Slips After Closing
Falling under 1.00 after closing does not trigger anything on its own. It matters at the next transaction. A refinance or cash-out reads the ratio again, using trailing history. If bookings softened or insurance climbed, the grid at that point may carry a lower cap than the one you started with. Investors planning a cash-out in a year or two should stress-test the property against that future read, not only today’s.
How to Model the Deal Before You Make an Offer
- Apply the haircut before you calculate the ratio.
- Stress-test insurance and taxes upward.
- Ask for the lender’s grid, not a headline leverage figure.
- Find out which appraisal rent form is used.
- Check whether the property trips a second cap, such as condo or multi-unit.
- Confirm the credit tier and reserve requirement for the band you are in. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
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. 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.

Frequently Asked Questions
Is there one fixed LTV cut when DSCR drops under 1.0?
No. The cut comes from each lender’s grid and shifts with credit score, loan size, transaction type, and property type. Market surveys report a range of reductions, but those are not network figures. Ask for the actual grid on your scenario.
Can an Airbnb investor still get a loan with coverage below 1.00?
Yes, through select lenders in the network, with leverage and terms adjusted. Most standard programs start at 1.00, and the sub-1.00 path is separate. Expect more cash down and often more reserves, subject to lender guidelines and credit approval.
Why does my Airbnb fall under 1.00 when the platform revenue looks strong?
Lenders typically haircut gross STR income before running the ratio, and the factor differs by lender. Insurance and taxes also sit in the denominator. Raw revenue is not the qualifying income.
What happens to cash-out proceeds if the cap drops?
They shrink. STR cash-out tops out around 70% LTV at 1.00 or better, and a lower cap on a sub-1.00 file reduces the equity you can pull by the same number of points of value. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Does a bigger down payment fix a sub-1.00 file?
It helps the ratio by lowering the payment, but it does not remove credit floors, reserve rules, or property eligibility. A lender still reads the full file.
