The Quick Read: A lender can still count income on a short-term rental you have never hosted, but only through an income source its program accepts. On a purchase, that usually means an appraiser’s short-term rental analysis, a third-party projection, or the long-term market rent as a fallback. Which one governs depends on the lender and the file.
- The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
- With no history, the real question is which income number the underwriter is allowed to use.
- Across the network, short-term rental purchases reach up to 75% LTV with a 640 minimum score and a 1.00 coverage floor.
- Clearing 1.00 does not mean the property makes money. Repairs, vacancy, and management sit outside the ratio.
- Short-term rental rules vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income.
A first-time host has no booking calendar, no platform statements, and no deposits to show. That feels like a dead end. It isn’t, but the path is narrower than with a long-term rental, and it runs through one decision: which income figure counts. The rest of this piece walks through that decision step by step. For the broader picture, the brokerage’s complete DSCR loans guide covers the product from the top.

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.
What Is the DSCR Formula for a Short-Term Rental?
The formula is monthly qualifying income divided by the full monthly housing obligation. That obligation is PITIA: principal, interest, taxes, insurance, and any HOA dues. A ratio of 1.00 means the income equals the payment. A ratio of 1.25 means the income is 25% larger than the payment.
Nothing about your paycheck enters the math. The lender looks at the property. That is why a DSCR loan suits an investor whose traditional personal-income documentation shows little income, or who is buying a fifth property and has stopped caring about debt-to-income ratios.
On a long-term rental, the income number is easy: a lease, or a market rent estimate. On a short-term rental, it is harder. Nightly rates swing by season. Occupancy swings with them. And a brand-new listing has produced exactly zero dollars. So the underwriter needs a stand-in for history.
Key Terms Defined
DSCR (debt service coverage ratio): A ratio comparing a property’s qualifying rental income to its full monthly payment.
PITIA: Principal, interest, taxes, insurance, and HOA dues. It is the payment side of the ratio.
LTV (loan-to-value): The loan amount as a percentage of the property’s value or price.
ADR (average daily rate): The average nightly price a short-term rental earns on nights it books.
Projection: A model that estimates a listing’s revenue from the results of similar nearby listings.
Haircut: A discount a lender applies to projected income before using it in the ratio.
Form 1007 and Form 1025: Appraisal forms for rent analysis. The 1007 covers single-family properties and the 1025 covers two-to-four-unit properties. Both typically estimate long-term lease income.
Seasoning: A waiting period a lender expects, such as time owning a property before a cash-out refinance.
Where Does the Income Number Come From With No History?
With no history, the file typically rests on one of three things. Most programs accept some of them and not others, and that varies lender by lender across the network.
| Income route | Who produces it | Typical weakness |
|---|---|---|
| Appraiser STR analysis | The appraiser | Depends on the appraiser’s comps |
| Third-party projection | A data vendor’s report | Can run high; thin markets drift |
| Long-term market rent | Appraisal rent schedule | Often well below STR income |
The appraiser’s analysis. Some programs let the appraiser research local short-term rental comps and estimate what the property would earn as a vacation rental. The appraiser looks at nightly rates, occupancy, bedroom count, amenities, and location.
The projection. Other programs accept a report from a data vendor. AirDNA’s help center explains that its Rentalizer tool estimates revenue, ADR, and occupancy from the historical performance of similar nearby active listings. It searches for comps within a 10-mile radius, shows month-by-month projected revenue with a range, and lets users build a custom comp set instead of accepting the algorithm’s pick.
The fallback. If a program won’t count short-term income without history, it uses long-term market rent from the appraisal. That figure is often significantly lower than what the same house earns on a booking platform. A property that clears 1.00 on vacation-rental income can come in short on long-term rent.
Which route governs? Across the network, there is no single rule. Some lenders accept a projection on a purchase. Others want the appraiser’s analysis. A few use whichever is lower. Ask before you pay for any report.
How Underwriting Treats a Projection, Step by Step
Here is the sequence on a typical no-history purchase.
1. Legality check. The rental has to be allowed at that address. Local permits, zoning, and HOA rules can decide the loan before the ratio does.
2. Income basis chosen. The lender names which evidence it will accept: appraiser analysis, projection, or long-term rent.
3. Evidence ordered. The appraisal comes back with a rent analysis. If the program takes a projection, that report is pulled too.
4. Adjustment applied. The lender may discount the projected figure before using it. Haircuts vary by lender, so treat any single number you hear as one lender’s choice.
5. Coverage computed. Qualifying income, after any adjustment, is divided by PITIA.
6. Leverage and credit tested. The ratio is only one gate. LTV, credit score, reserves, and property eligibility all have to clear too.
Step four is where first-time buyers get surprised. The projection is the vendor’s number. The qualifying income is the lender’s number. They are rarely the same.
Why Lenders Adjust Projections
A projection is a model, not a meter reading. AirDNA’s homepage describes estimated host revenue as booked nights times ADR, plus cleaning fees, minus discounts and platform service fees. Because cleaning fees are folded in, an STR educator at 10XBNB advises stripping them out when you sanity-check the figure.
Accuracy also depends on the market. The same 10XBNB review reports that projections in small markets can drift 15 to 30 percent either way, and that markets with fewer than 100 listings produce very wide uncertainty. A separate STR data educator, VaultSTR, argues that independent tests put Rentalizer 15–30% off actual results, usually on the high side, and suggests underwriting year one at 60–75% of the projection. That is one educator’s opinion, not an underwriting rule. But it explains why a lender would shave the number.
The practical read: lenders adjust because projections can run optimistic, and a lender who funds on an inflated number carries the risk. Investors should do the same shaving before they offer, not after.
A Worked Example: Same House, Three Income Routes
Run the numbers on a hypothetical three-bedroom house. These are illustrative modeled assumptions, not market data, and they use ratios only.
Assume the payment obligation is the same under every route. Only the income figure changes.
| Route | Qualifying income | Resulting coverage |
|---|---|---|
| Long-term rent (1007) | Lowest of the three | Around 0.85x |
| Projection after a lender haircut | Middle | Around 1.10x |
| Appraiser STR analysis | Highest | Around 1.30x |
Same house. Same payment. A coverage ratio ranging from short of 1.00 to comfortably above it, purely on which evidence the lender accepts.
Now the sub-1.00 case. At 0.85x, the file falls below the standard 1.00 floor for short-term rental purchases. Paths exist. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. A larger down payment can lift the ratio by shrinking the payment. Switching to an evidence route the lender accepts can lift the numerator. Whether any of this works depends on lender guidelines, credit approval, and property review. It is a set of options to explore, not a promise.
What Happens When the Ratio Comes Up Short
Start with a more affordable fix and work outward.
- Change the evidence route. If the lender counted long-term rent, ask whether an appraiser’s STR analysis or a projection is allowed under a different program.
- Lower the leverage. A bigger down payment cuts the payment and can lift coverage. It does not erase credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
- Review a select-lender path. Sub-1.00 coverage is available through select lenders in the network, with leverage and terms adjusted.
- Consider term structure. Extended terms (40-year) and interest-only periods are available through select lenders in the network, and they can change the payment side of the ratio. The spine of most files is the 30-year fixed.
- Pick a different property. Sometimes the honest answer is a house in a market with stronger comps or a lower price.
- Build history first. Another path is to buy, host, and let the history accumulate. A short-term rental refinance generally expects about 12 months of hosting history, so months of real bookings become the evidence.
Purchase, Refinance, and the Two Clocks
There are two separate clocks, and first-timers blur them.
The hosting clock measures how long you have actually operated the rental. Short-term rental programs across the network generally expect about 12 months of host experience. A purchase with no history is the case where projections and appraiser analysis stand in for it.
The ownership clock is seasoning, the waiting period before a refinance. Cash-out files commonly expect about 6 months of ownership.
On a short-term rental, the network figures are: purchase to 75% LTV, refinance up to 70%, and cash-out up to 70% on short-term-rental collateral. A standard long-term rental can reach 75% on a cash-out. Purchase and refinance each carry a 1.00 coverage floor in the select programs that set one. A 640 credit score is the usual minimum for short-term rental files. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
The sequencing most first-timers follow: buy on a projection or appraiser analysis, host for a year, then refinance on real platform statements and bank deposits. That real history is stronger evidence than any model. It can also open better pricing and leverage.
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.
Which Loan Fits a First Short-Term Rental?
| Factor | DSCR loan | Conventional | Bank-statement loan |
|---|---|---|---|
| What is evaluated | The property’s income | Your personal income | Your deposits |
| Counts projected STR income | Some programs | Rarely | No |
| Looks at the property’s earning power | Yes | Barely | No |
A conventional loan weighs your income and debts and has no clean way to count projected vacation-rental income. A bank-statement loan is reviewed around documented deposits, so the property’s earning power barely matters. DSCR is the only one of the three built around the property’s own income. The brokerage’s comparison of DSCR and conventional investment loans goes deeper if you are weighing both.
Past the income number, other program facts matter. Across the network, purchase leverage on standard rentals mostly lands at 75% to 80% LTV, and a select high-leverage tier reaches 85% LTV with roughly a 700+ score. Short-term rentals sit lower, as noted above. Most programs want about a 660 score. Reserves vary by lender, leverage, loan size, and transaction type, and commonly run around 6 months of PITIA. Standard loan sizes run up to $3,000,000. All of this is subject to lender guidelines and not a commitment to lend.
Where the General Rule Breaks
Thin and rural markets. Few comps mean wide error bars. A projection built on a handful of listings is a weak foundation, and lenders know it.
Projection volatility. Vendor models get updated. A projection that supports your offer can look different when the report is re-pulled. Underwrite your own number with room to spare.
Seasonality. Qualifying income uses an annual average, not peak summer. A beach house that books solid for ten weeks and sags the rest of the year still gets averaged.
Converted long-term rentals. If you already own a long-term rental and convert it, the history clock starts when hosting starts. Prior lease income is not hosting history.
Multi-unit properties. Two-to-four-unit properties are appraised on the 1025 form, and the income analysis has more moving parts.
Ineligible property types. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs, whatever the rental income looks like.
Entity ownership. Many investors hold the property in an LLC, subject to lender program eligibility.
Coverage Is Not Cash Flow
This catches new hosts more than anything else. DSCR compares income to PITIA only. It leaves out repairs, vacancy, management, cleaning, utilities, supplies, and capital expenses. A deal can clear 1.00 and still lose money each month.
Short-term rentals carry heavier operating costs than leases. A typical host pays for cleanings between guests, restocks supplies, covers utilities, and often pays a property manager. A first-timer also faces furnishing and startup costs that never appear in the ratio. Build your own expense model beside the lender’s. If the ratio only works with a rosy projection and the cash flow only works at peak occupancy, the deal is thin.
Practitioner observation from comparable files: investors who underwrite their own year-one income well below the vendor projection tend to be the ones still comfortable after the first slow season.
Common Misconceptions
No history means no loan. Projection-based and appraiser-based underwriting exist for exactly this case. Acceptance is lender-dependent.
The projection is the coverage figure. Programs may discount it, require a recent report date, or limit it to purchases.
1.25 is required. That figure is a commercial lending convention. Residential DSCR programs set their own floors, and 1.00 is where select programs start.
DSCR equals profit. The residential ratio is gross income over PITIA. It is not net operating income.
Questions to Ask Any Lender Before You Pay for a Report
1. Does this program accept a projection, an appraiser’s STR analysis, or only long-term rent on a purchase?
2. Is the projected figure discounted before it goes into the ratio?
3. If the appraisal’s rent schedule comes back low, what happens to my coverage?
4. Which report vendors and comp standards do you accept?
5. What leverage and reserves apply to a short-term rental purchase?
6. What do you need to see to prove the rental is legal at this address?
Asking in this order prevents the expensive mistake: paying for a report the lender won’t use.
Frequently Asked Questions
Can I get a DSCR loan on a short-term rental I have never hosted?
Usually yes on a purchase, if the program accepts a projection or an appraiser’s STR analysis. Some programs fall back to long-term market rent. Eligibility depends on lender guidelines, credit, and property review.
Does a converted long-term rental count as hosting history?
No. Hosting history starts when you begin hosting guests. Months of lease income show the property can rent, but they are not short-term rental history. Plan on the host-experience expectation of about 12 months for refinancing.
Does coverage above 1.00 mean the property is profitable?
No. The ratio compares income only to PITIA. Management, cleaning, repairs, utilities, vacancy, and capital costs sit outside it. A property can clear the ratio and still run tight.
What if the long-term rent comes in too low for 1.00?
Several options may apply: a different evidence route, lower leverage, a larger down payment, or a select-lender path for coverage below 1.00, with leverage and terms adjusted. Each is reviewed subject to lender guidelines.
What credit score and leverage apply to a short-term rental purchase?
Across the network, expect a 640 minimum score and leverage up to 75% LTV on a purchase, with a 1.00 coverage floor. Cash-out and refinance on short-term-rental collateral top out around 70%. Programs change and every file is underwritten individually. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
