The Quick Read: The rental income a lender will count, divided by your target coverage ratio, gives the largest monthly payment the property can carry. That payment limits the loan, and the loan, combined with the leverage cap, limits the price you should offer.
- Counted income is not the gross booking number. Lenders discount it, and the discount varies by lender.
- Taxes, insurance, and HOA dues come out of your payment budget before principal and interest do.
- Leverage on a short-term rental purchase tops out at 75% LTV (loan-to-value, the loan as a share of the property’s value) on the strongest files.
- The loan size that coverage allows and the loan size that leverage allows are two separate limits. The smaller one wins.
- Clearing the coverage test does not mean the property makes money.
Most buyers do this in the wrong order. They fall for a listing, offer near the asking price, and then find out what the file can support. The better order starts with the income a lender will count and ends with a price.
This article walks through that reverse calculation. It covers what counts as income on a short-term rental, how the haircut works, where the appraisal fits, and what to do when the asking price sits above your number. For the full loan mechanics, see Lendmire’s complete DSCR loans guide.
Key Terms Defined
DSCR (debt service coverage ratio): On a residential investor loan, this is the property’s counted monthly income divided by its monthly PITIA.
PITIA: Principal, interest, taxes, insurance, and association dues. It is the full monthly obligation on the property.
Counted income: The income figure a lender actually uses after its own discount. It is usually lower than what the booking calendar shows.
Haircut: The percentage a lender subtracts from gross short-term rental income to allow for vacancy, cleaning, platform fees, and management.
TTM (trailing twelve months): A statement of the property’s actual income over the last twelve months.
ADR (average daily rate): The average price paid per booked night.
Target coverage: The DSCR you want the file to show. It is your choice, and it sits at or above the program floor.
What Does a Lender Count as Income on a Short-Term Rental?
A short-term rental has no lease, so income comes from either history or a projection. History means twelve months of platform payouts, property-manager statements, or bank deposits that reconcile to those payouts. A projection is a modeled estimate from a data service or an appraiser’s short-term rental analysis.
An operating property is the cleanest case. Across the network, files with a real trailing-twelve-month record tend to move through review with fewer questions. The history also fits the program, since short-term rental programs usually expect about 12 months of host experience from the borrower.
A property with no operating record is harder. The file leans on a market projection report or an appraiser’s analysis. HousingWire notes that nightly pricing, seasonality, event spikes, cleaning and management costs, and local rules do not fit neatly on the standard rent schedule form.
Some programs in the network will credit a projection. Others will not, and the fallback in that case is a long-term rent schedule. Ask which basis the lender uses before you write the offer, because the same house can produce different ratios under different programs.
The Haircut Is the Number That Matters
Lenders do not take gross bookings at face value. They reduce short-term rental income by a percentage before dividing by PITIA, and the percentage depends on the lender and the program. The network does not share one factor, so confirm the factor for the specific program before you build the offer around it.
The practical effect is simple. Strong bookings do not raise your ceiling if the counted income is discounted or capped by a weak document. The seller’s gross revenue claim is a talking point. The discounted figure is the input.
Many buyers also err on the other side of the estimate itself. Third-party reviewers say AirDNA’s Rentalizer projection can run optimistic. Vault STR suggests modeling year one at 60% to 75% of the projection, and it warns that blocked calendar dates can read as demand. That is one advisor’s opinion rather than a lender guideline, but it is a sensible stress test.
The Reverse Calculation, Step by Step
Here is the full chain. The figures below are modeled assumptions on an index, not market data and not dollar amounts. Call counted monthly income 100.
1. Choose your target coverage. Say you want 1.25x, which leaves a cushion above the 1.00 floor where select short-term rental programs start.
2. Divide counted income by the target. 100 divided by 1.25 is 80. That is the most PITIA the property can carry.
3. Subtract taxes, insurance, and HOA dues. Say those take 20 of the 80. That leaves 60 for principal and interest.
4. Convert that payment into a loan. A lender’s payment factor turns the 60 into a maximum loan. The calculator on this site can illustrate that step.
5. Apply the leverage cap. The coverage-supported loan is one limit. The leverage-supported loan is another. Take whichever is smaller.
6. Convert the loan to a price. On a purchase at 75% LTV, the price ceiling is the loan divided by 0.75, so the price is about 1.33 times the loan. At lower leverage, divide by that lower percentage. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Notice how much room taxes and insurance take. On a short-term rental, the insurance quote should reflect short-term use, which can differ from a standard landlord policy. A quote that comes in high shrinks the principal-and-interest slice in step three and lowers the price ceiling.
The chain also runs in the other direction. If you already have an asking price, work forward: loan, payment, ratio. If the ratio misses your target, you know the gap before you offer.
Which Cap Binds First?
Three limits apply to every offer, and the one that binds first sets your ceiling.
| Limit | What sets it | When it binds |
|---|---|---|
| Coverage | Counted income vs. PITIA | Low-income or high-tax/insurance properties |
| Leverage | LTV cap on value | Strong-income properties |
| Cash | Down payment, reserves, setup | Thin liquidity |
On a short-term rental purchase, leverage tops out at 75% LTV on the strongest files, which means a down payment of at least 25%. Refinance programs run lower, around 70% LTV, and cash-out on short-term rental collateral also tops out at 70% LTV. Expect a credit score of 640 or higher, and loan sizes up to $3,000,000 on standard programs, all subject to lender guidelines.
A larger down payment lowers the monthly payment and can lift the ratio. It does not erase the leverage cap, the credit floor, the reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Reserves vary by lender, leverage, loan size, and transaction type. Around six months of PITIA is common, with conservative, lower-leverage files sometimes seeing reserves waived. Budget for the closing costs and furnishing cash on top of that.
What the Appraisal Does and Does Not Do
The appraisal sets value, and value drives LTV. A low appraisal cuts the loan through leverage even if income is strong, so it can break an offer that looked fine on coverage alone.
The appraisal does not decide how income counts. The lender does. McKissock, an appraiser-education publisher, explains that Form 1007 covers one-unit houses and condos, while Form 1025 covers two- to four-unit properties. It also notes that short-term rentals are priced nightly and behave more like hotels than monthly rentals. Furniture, fixtures, and equipment are part of the picture too.
That is why appraisers should not multiply a nightly rate by 30 and call it rent. HousingWire also warns that misusing the form can distort the coverage ratio. It adds that the new appraisal data standard will retire legacy forms, which keeps narrative addenda important.
On a two- to four-unit property, the appraisal reports rent unit by unit. The lender decides separately whether short-term income is credited.
Which Income to Count on Offer Day
Use two numbers: what you expect and what the lender will likely count. Build the offer on the lower one.
Start with the actual operating record if one exists. Reconcile the platform statements to the bank deposits, and check that the figures match. A seller’s spreadsheet that does not reconcile is a marketing document.
If there is no record, pull a projection and read its confidence score. AirDNA’s calculator page says each projection carries a Comp Set Strength score of Low, Medium, or High, which reflects how consistent revenue is across the comparable listings. A Low score is a reason to haircut harder.
Know what the data measures. AirDNA’s help page defines occupancy as reserved days divided by active listing nights over the last twelve months. A recent AirDNA snapshot put the U.S. average at 57.2% occupancy and a $258.91 ADR for a single May, which is context for a national average, not a forecast for your property.
A trailing-twelve-month statement smooths out seasonality, and a peak-season snapshot does not. If a seller shows you summer numbers, ask for the full year.
Finally, run the math on both the projected short-term income and the supportable long-term rent. The gap between them tells you how much of the price depends on the short-term thesis.
Where the Rules Break
A few cases do not follow the standard sequence.
- Projection versus history. Projected income gets more scrutiny, and whether a program counts it at all is lender-specific.
- Commercial versus residential. The commercial formula is net operating income divided by annual debt service. The residential investor loan divides gross or discounted rent by PITIA. Mixing the two causes real confusion.
- Legality. An appraisal does not prove a short-term rental is legal. 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.
- Property type. DSCR financing is not offered in the network on manufactured homes (single- and double-wide), log homes, or barndominiums.
- Coverage below 1.00. 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
One more caution applies to every case. Clearing 1.00 is not positive cash flow. Repairs, vacancy, cleaning, management, utilities, and capital expenses all sit outside the ratio.
What Happens When the List Price Is Above Your Number?
You have five levers, and each has a tradeoff.
- Negotiate the price down. Use the coverage math as the rationale. A counter-offer that says the property supports a lower payment is easier to defend than one based on a feeling.
- Put more down. This lowers the payment and raises the ratio. It still cannot lift you past the leverage cap, and it costs liquidity.
- Use a more conservative income assumption. This lowers the ceiling honestly rather than raising it with optimism.
- Look at a sub-1.00 path. It is available through select lenders in the network, with leverage and terms adjusted. That generally means more cash in and a tighter structure.
- Walk away. This is the right call more often than buyers want to admit.
Interest-only periods and longer terms exist through select lenders in the network, and they lower the payment on paper. Treat them as structure choices with tradeoffs, not as a way to rescue a price that does not work.
Here is how the offer ladder works. Open near the price your conservative income supports at a comfortable cushion. Set your target where counted income clears the floor with room to spare. Set your walk-away where the file clears the floor with nothing left, because a file sitting right at 1.00 has no room for a higher insurance quote or a lower appraisal.
Pre-Offer Checklist
- Confirm the short-term use is allowed locally and by the HOA.
- Get an insurance quote that reflects short-term rental use.
- Estimate taxes, and remember that assessments can shift after a sale.
- Gather the purchase contract, platform or manager statements, matching bank deposits, and HOA documents.
- Order or pull a projection report if there is no operating record.
- Confirm reserves and the cash needed for closing and furnishing.
- Check that you understand the lender’s income basis and haircut.
- Run the math at the counted income and at a lower stress case.
Tax treatment varies; consult a qualified professional.
Mistakes That Move the Ceiling
Buyers anchor on seller-quoted gross revenue and never separate it from counted income. They use citywide averages when neighborhood-level comparables are what matter. They offer first and test coverage later, which is how re-trades and failed appraisals happen.
Many investors also forget that insurance and taxes change the ceiling before principal and interest do. A single high insurance quote can reduce the supportable price more than a small change in income.
This chain compares across property types too. Lendmire’s pieces on how to set a maximum offer price on a short-term rental condo and how to set a maximum offer price on a short-term rental cabin show how HOA dues and rural comparables change the inputs.
Frequently Asked Questions
How does DSCR work on a short-term rental?
It works like any DSCR file: counted monthly income divided by monthly PITIA. The difference is the income side. With no lease, the lender uses a trailing-twelve-month record or a projection, then applies a discount before dividing.
Can I get a loan if the ratio is below 1.00?
Possibly. 1.00 is where many select programs start, and a separate select-lender path takes coverage below 1.00. Leverage and terms are adjusted, which usually means more cash down. Eligibility depends on lender guidelines, credit, reserves, and property review.
What if the appraisal or income comes in low?
A low appraisal cuts value, which cuts the loan through the LTV cap. Low counted income cuts the loan through coverage. Either can force a lower price, more cash down, or a different program, so build the offer with some cushion.
Does interest-only change the offer ceiling?
Yes, it can. Interest-only periods are available through select lenders in the network, and they lower the payment during that period. That can raise the supportable price on paper, but the structure carries tradeoffs, so size the offer on a fully amortizing basis first.
Does a 1.00 ratio mean the property is profitable?
No. The ratio compares counted rent to PITIA only. Repairs, vacancy, cleaning, management, and utilities all sit outside it.
Work the Number Before You Write the Offer
If you are buying or refinancing a rental property and want to see how the numbers work, Lendmire can help you compare DSCR loan options based on the property income, credit profile, leverage, and investor goals. As a mortgage broker, Lendmire arranges these loans through select lenders in its wholesale network, with investor programs across 41 markets, including Washington, D.C. Programs change, and every file is reviewed under lender guidelines. This is not a commitment to lend.
The chain is short: counted income sets the payment, the payment sets the loan, and the loan, under the leverage cap, sets the price. A buyer who follows that order never has to ask what the property is worth to a lender after the offer is already signed.
