The Quick Read: Build a realistic annual revenue figure from documented bookings or a market projection, reduce it the way a lender would, then divide it by the full monthly housing payment (principal, interest, taxes, insurance, and any HOA dues). Run that ratio against long-term market rent as a fallback, because underwriting often lands between the two numbers. Short-term rental rules vary by city, county, HOA, and property type, so confirm local rules before relying on projected income.
- Revenue comes from 12 months of hosting history on an operating property, or a market-data projection or appraiser analysis on a new purchase.
- Nightly rate times 30 is not a monthly rent figure, and lenders do not treat it as one.
- Short-term rental programs in Lendmire’s network typically reach 75% LTV on a purchase, with a 640+ credit score and a 1.00 coverage floor on purchases.
- Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, and management sit outside the ratio.
- Run three versions before applying: your estimate, a haircut version, and a long-term-rent fallback.
What Is a DSCR Lender Actually Testing?
A DSCR lender tests one thing: whether the property’s income covers its own monthly housing payment. The formula is qualifying monthly income divided by monthly principal, interest, taxes, insurance, and HOA dues. A result of 1.00 means income equals the payment. Higher means more cushion.

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.
For vacation rentals, the hard part is the numerator. A long-term lease gives the lender one clean number. A nightly-rate property gives a moving target, so the lender needs a defensible way to turn bookings into a monthly figure. That is what this article walks through. For the broader mechanics, Lendmire’s complete DSCR loans guide covers the program from the ground up.
One framing point matters before any math. Your own profit model and the lender’s qualifying income answer different questions. Your model asks whether the property makes money after every expense. The lender asks whether income covers the payment. DSCR compares rent to the housing payment only. Repairs, vacancy, management fees, utilities, and capex sit outside it.
| Question | Lender qualifying income | Your profit model |
|---|---|---|
| Purpose | Does income cover the payment? | Does the deal make money? |
| Starting point | Documented or projected revenue | Your own booking assumptions |
| Adjustment | Program haircut on gross | Full expense build |
| Payment side | Principal, interest, taxes, insurance, HOA | Same, plus operating costs |
| Output | Coverage ratio | Cash-on-cash, net yield |
Key Terms Defined
ADR (average daily rate): The average price a booked night actually earns, after discounts.
Occupancy rate: The share of available nights that are booked.
Haircut (income factor): The percentage reduction a program applies to gross short-term revenue before counting it as qualifying income.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly housing payment.
Form 1007: An appraiser’s single-family rent schedule, built on monthly leases.
Form 1025: The appraiser’s small-income-property report for two to four units, also built on monthly leases.
Rentalizer-style projection: A modeled revenue estimate from a data provider, built from comparable listings rather than the property’s own history.
Which Evidence Path Applies to Your Property?
Your evidence path depends on whether the property already operates as a short-term rental. Most programs weigh three sources: your documented hosting history, a third-party market projection, or the appraiser’s rent opinion. Which one carries the file depends on your situation.
An operating property. Twelve months of history is the strongest evidence. Typical documents are platform payout or host-dashboard exports, property-management-software reports, and bank statements that reconcile platform earnings to actual deposits. Keep other properties’ income and unrelated deposits out of the stack. Use the full 12 months so seasonality shows up honestly. A beach house that earns most of its revenue in a few summer months looks very different in a three-month snapshot than across a year.
A new purchase with no history. The file leans on a market-data projection or the appraiser’s short-term-rental analysis. Short-term rental programs in Lendmire’s network typically expect about 12 months of hosting experience from the borrower, so a first-time host should talk to a broker about structure before writing an offer. Some programs also set requirements for the projection report itself, such as a recent report date and matched comps.
The fallback. A long-term rent opinion from the appraiser can cap or rescue the file. It is often the number that decides the outcome when short-term evidence is thin.
| Situation | Typical primary evidence | Fallback |
|---|---|---|
| Operating, 12+ months of records | Documented bookings | Long-term market rent |
| New purchase, experienced host | Projection or appraiser STR analysis | Long-term market rent |
| Converted long-term rental | Often long-term rent until history builds | Records over time |
| Refinance of operating STR | Documented history | Long-term market rent |
How Do You Estimate Gross Revenue Yourself?
Estimate gross revenue with a simple formula: occupancy rate times days in the month times ADR. BiggerPockets lays out that approach and recommends checking comparable listings’ calendars across the whole year to capture seasonality. The annual version is ADR times occupancy times 365.
Run it month by month rather than as one annual average. A twelve-row sheet with a separate occupancy and ADR for each month shows you the slow months a lender will count and a peak-season pro forma will hide. Lenders typically annualize, so a strong July does not rescue a weak February.
Know what your data source counts. AirDNA’s help center explains that its revenue figure is built from nightly rates plus cleaning fees, minus service fees and discounts, on booked days. Investors in a BiggerPockets forum thread on analyzing a short-term rental point out that some data can include occupancy taxes, cleaning fees, and pet fees, so strip those out to get closer to true net income.
Projections are estimates. Property-level models can miss in either direction, and unusual amenities or finishes rarely show up in the numbers. One investor in a BiggerPockets thread on AirDNA accuracy found the tool under-projected a specific property, and the practical lesson there is to cross-check more than one source rather than trust a single model.
Why Nightly Rate Times 30 Fails
Multiplying a nightly rate by 30 overstates income, because it ignores vacancy, furnishings, services, and business expenses. The Fannie Mae appraiser update says Form 1007 was not designed for appraising single-family homes used as short-term rentals. It also calls multiplying nightly comps by 30 incorrect. That is agency material, and DSCR loans are not agency products. It is useful here only because it explains what the appraisal forms can and cannot do.
The practical result: the rent schedule uses monthly leases, so a strong nightly-rate property can look weak on it. A 1025 on a two-to-four unit short-term rental has the same monthly-lease limit. McKissock, an appraiser-education provider, adds two points worth knowing. Appraisers value the real property, not furnishings or business income, and the lender makes the final call on how income is treated.
So the appraiser does not decide your short-term income. The lender’s program does.
Step by Step: From Revenue to a Coverage Number
Work through five steps before you submit anything.
1. Pick the evidence path. Operating history, projection, or appraiser analysis, as above.
2. Estimate gross revenue. Use the month-by-month sheet. Reduce platform “revenue” for taxes and pass-through fees.
3. Apply a haircut. Across the wholesale network, programs generally count only a percentage of gross short-term revenue. Ask your broker which factor applies to your file instead of assuming one.
4. Divide by the full payment. Include principal, interest, taxes, insurance, and any HOA dues. Taxes and insurance vary by county and property, so use real quotes rather than guesses.
5. Stress-test against the fallback. Compute the ratio on long-term market rent as well, then see which number the program will actually use.
Here is how the three scenarios compare in structure. These are modeled assumptions, not market data.
| Scenario | Income used | Typical read |
|---|---|---|
| Your estimate | Gross, no haircut | Optimistic, not what underwriting uses |
| Haircut version | Gross reduced by program factor | The realistic coverage number |
| Long-term fallback | Appraiser’s monthly rent | The floor, and sometimes the binding number |
Say your haircut version lands around 1.15x and your long-term fallback lands near 0.90x. That tells you something real. The file clears on short-term income, so the evidence path matters a great deal, and a program that relies only on the rent schedule would struggle. Now flip it: a strong long-term number and a thin short-term one means the conservative structure carries the file.
Reverse Math: What Income Do You Need?
Work backward from the target. Start with the full monthly payment, multiply by the coverage you want, then divide by the program’s income factor. The result is the gross monthly revenue you need to document. From there, divide by days in the month to get a daily revenue target, and test it against ADR and occupancy. If hitting 1.00 needs 85% occupancy at an ADR above what your comps earn, the deal does not pencil on short-term income. Skip it, or restructure.
Reverse math also shows how a larger down payment helps. A lower balance means a lower payment, which can lift the ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility, though. The strongest files clear both tests: enough equity and enough rental coverage.
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.
What Do Short-Term Rental Programs Typically Expect?
Across the wholesale network, short-term rental financing runs tighter than standard long-term rental financing. Typical ranges, subject to lender guidelines and individual underwriting:
- Purchase leverage: up to 75% LTV on the strongest files.
- Refinance and cash-out: up to 70% LTV on short-term-rental collateral, versus 75% on standard rentals.
- Credit: a 640+ score is the working minimum.
- Coverage: 1.00 on purchases and refinances. Some select programs begin there. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
- Experience: about 12 months of hosting history is the usual expectation.
- Loan size: up to $3,000,000 on standard programs.
- Reserves: they vary by lender, leverage, loan size, and transaction type, commonly around six months of PITIA.
Properties outside the network’s DSCR programs include manufactured homes (single- and double-wide), log homes, and barndominiums. They are not offered.
Where the General Rule Breaks
Converted long-term rentals. With no hosting history, underwriting often falls back to long-term rent until you have 12 months of records. Converting a tenant-occupied property does not give you instant short-term credit.
Weak short-term markets. If nightly income barely beats a lease, the long-term number may be the better one to qualify on, and the cleaner one to underwrite.
Strong short-term markets. A program that uses only the rent schedule can fail coverage even when nightly income would clear it easily. That mismatch is why you ask which evidence a program accepts before you choose a property, not after.
Thin or noisy projections. Independent commentary suggests projections can vary widely in thin markets, so treat any single estimate as directional only. The safer habit is comparing several sources and trusting none blindly.
Local rules. Some permits are limited or non-transferable on sale, and a property that cannot legally operate as a short-term rental has no short-term income to count.
Second-home loans. These generally do not count rental income, so they are a different product with different logic.
Pre-Application Checklist
Before talking to a broker, gather and decide the following:
- Twelve months of platform exports and matching bank statements, if the property operates.
- A month-by-month revenue sheet with ADR and occupancy per month.
- Two or more independent projection sources, if buying new.
- Real tax, insurance, and HOA figures for the payment side.
- Coverage computed three ways: estimate, haircut, long-term fallback.
- Confirmation that short-term use is permitted at that address.
- A go, adjust, or walk rule decided in advance: go if the haircut version clears with cushion, adjust leverage or price if only the fallback clears, walk if neither does.
Questions worth asking the broker: which evidence path fits my property, what factor applies to it, how is the rent opinion used, and what reserves apply at my leverage.
Common Estimation Mistakes
- Modeling peak occupancy. Investors overshoot because they price in the best month. Lenders annualize.
- Counting gross as qualifying. Programs apply a factor, and platform revenue may include fees and taxes.
- Treating 1.00 as profit. It covers the housing payment, not operating costs.
- Trusting one data source. A projection is a modeled estimate, not a guarantee.
- Ignoring the fallback. The long-term number can bind the file.
- Skipping legal checks. Income that cannot legally exist cannot be counted.
A year of clean, platform-matching, bank-reconciled records also improves your documentation options on a later refinance. Lendmire’s piece How a Vacation Rental DSCR Loan Reconciles Manager and Platform Income goes deeper on that reconciliation step.

Frequently Asked Questions
Do I need hosting history to buy a vacation rental with a DSCR loan?
Not always, but short-term rental programs typically expect about 12 months of host experience from the borrower. A new purchase leans on a market projection or an appraiser’s short-term analysis, and some files fall back to long-term rent. A first-time host should discuss structure with a broker before making an offer.
Does the lender count 100% of my gross bookings?
Usually not. Programs generally apply a reduction to gross short-term revenue, and the factor depends on the program and the type of evidence. Documented history often fares better than a projection. Ask which factor applies to your file.
Can I use my own spreadsheet instead of a projection report?
Your sheet is the right starting point for pre-application math, but underwriting relies on documented history, a third-party projection, or the appraiser’s analysis. Your pro forma alone rarely drives the coverage ratio.
What happens if the short-term estimate clears but long-term rent does not?
It depends on which evidence the program accepts for your situation. A file with solid hosting history may qualify on short-term income. A program built only on the rent schedule may not. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted.
Does clearing 1.00 mean the property cash flows?
No. DSCR compares income to the housing payment only. Repairs, vacancy, management, utilities, and capex are outside the calculation, so build your own profit model alongside it.
