Short Term Rental Loans — The Quick Read: A short-term rental loan is almost always a DSCR loan — a mortgage that is reviewed on what the property’s booking income can cover, not on the borrower’s paystubs. Most programs in this space run purchases up to roughly 75% LTV, want a credit score in the 700 range, and expect somewhere around 12 months of hosting history before they’ll fully trust the income. Refinances and cash-out generally cap lower, near 70% LTV, with coverage measured against the property’s rent rather than the owner’s personal debt-to-income. The rest of this comes down to how the income gets measured, which forms show up in the appraisal, and where the standard playbook breaks down.
Key Takeaways
- STR financing runs through non-QM DSCR loans, not conventional mortgages — the property’s income drives lender review.
- Underwriters use the lower of two numbers: trailing rental history or a long-term market rent comparable from an appraisal form.
- Purchase leverage on STR properties generally tops out near 75% LTV; refinance and cash-out cap lower, around 70%.
- A DSCR clearing 1.00 means rent covers the mortgage payment — it does not mean the property is cash-flow positive after real operating costs.
- Coverage below 1.00 and no-ratio structures both exist through select lenders in the network, but they come with adjusted leverage and stricter conditions.
Key Terms Defined
DSCR (debt-service coverage ratio): the property’s monthly rental income divided by its full monthly housing payment — principal, interest, taxes, insurance, and HOA dues where they apply. A ratio at or above 1.00 means the rent covers that payment.

PITIA: shorthand for the full monthly obligation a lender counts against the property — principal, interest, taxes, insurance, and association dues.
Non-QM loan: a mortgage that sits outside the standard “qualified mortgage” box built around a consumer’s personal income and debt ratios. DSCR loans are one flavor of non-QM.
Business-purpose loan: a loan made to a borrower for an investment or rental property rather than a home they’ll live in. This distinction is what allows the loan to be underwritten around the property’s income instead of the borrower’s.
LTV (loan-to-value): the loan amount expressed as a percentage of the property’s value or purchase price. Higher LTV means less money down and less equity cushion.
Seasoning: the amount of time a lender wants to see between an event — usually a purchase or a rate change — and a refinance request.
What Actually Makes an STR Loan Different From a Regular Mortgage
An STR loan isn’t a separate product with its own name on a term sheet — it’s a DSCR loan applied to a property that earns its income nightly instead of monthly. That single fact changes almost everything about how the file gets built.
A conventional lender wants two years of traditional personal-income documentation, a debt-to-income calculation, and a paystub trail. A DSCR lender wants to know one thing: does the property’s rental income cover its own payment? For a long-term rental, that’s a simple lease amount. For a short-term rental, the income is seasonal, booking-platform-dependent, and often thinner on paper history — which is exactly why STR files get their own set of rules layered on top of the standard DSCR framework.
DSCR loans are designed for non-owner-occupied investment properties. Because they’re business-purpose investor loans, they’re reviewed differently from a standard owner-occupied mortgage — that’s what opens the door to qualifying on the rental income rather than the borrower’s traditional personal-income documentation. For a full breakdown of how the ratio itself works, Lendmire’s complete DSCR loans guide walks through the mechanics from the ground up.
How Underwriting Treats Short-Term Rental Income, Step by Step
Step 1: The Ratio Itself
Every DSCR file starts with rent divided by PITIA. On most standard DSCR programs, 1.00 coverage is a starting floor a lender may work with — never a universal rule — and stronger ratios generally unlock better pricing and leverage. Picture a beachside condo with average monthly booking income landing around 1.18 times its full payment once taxes and insurance are folded in — that’s a file with cushion; one that lands at 1.02 is one that clears the bar with almost nothing to spare.
Step 2: Establishing the Income Number
This is where STR underwriting splits from a normal long-term rental file. Instead of a single lease amount, the lender typically looks at two numbers and uses the lower one: the trailing 12-month average of actual short-term rental income, and a comparable long-term market rent pulled from the appraisal exhibit. A property with no operating history yet defaults straight to that market rent comparable, or to third-party rental data.
Step 3: Gross Income vs. Net Income
Lenders work off gross booking revenue — the total money collected before cleaning fees, management costs, or platform fees come out — not the owner’s net take-home. Most programs then apply some discount to raw projected STR revenue before running the ratio. That discount isn’t standardized across the industry; it moves file to file and lender to lender, so nobody should assume a fixed percentage applies universally.
Step 4: The Appraisal Exhibit
For a single-family STR, the appraiser fills out Fannie Mae’s Form 1007 rent schedule; for a 2-4 unit STR, it’s Form 1025. Even though DSCR loans are never sold to Fannie Mae, non-QM lenders borrowed this exact form-naming convention because it’s the industry’s standard exhibit for documenting comparable rental rates. Here’s the part that trips people up: the appraiser’s job is to document a long-term monthly rent comparable — not to assess the property’s actual short-term booking income. That decision belongs to the lender, not the appraiser.
Step 5: Filling the Gap With Market Data
A property with no hosting history yet still needs a number to underwrite against. Lenders commonly turn to third-party STR data platforms that estimate projected nightly and monthly revenue by pulling comparable properties within a set radius and weighting their historical performance. These tools help bridge the gap for a brand-new STR purchase, but they supplement the appraisal comparable — they don’t replace it.
Step 6: Reserves and File Completion
Once the income number is set, the deal works to reserves, title review, and final DSCR compliance. Reserve requirements vary by lender, leverage, loan size, and transaction type — commonly landing around six months of PITIA held in liquid accounts, sometimes waived on conservative rate-term refinances at lower leverage under roughly $1.5 million, and stepping up toward nine months on larger loan balances.
What Loan Structures Are Available for STR Properties
DSCR isn’t the only tool in the box, but it’s usually the right one once a property is meant to be a business, not a residence. Here’s how the main options stack up:
| Structure | Reviewed on | Best Fit | Watch For |
|---|---|---|---|
| DSCR / STR loan | Property rental income | Buy-and-hold STR investors | Coverage and hosting history requirements |
| Conventional / second-home | Borrower’s personal income | Occasional personal-use property | Restricted rental activity, DTI limits |
| Investment-property HELOC | Existing equity + income | Tapping equity without a refi | Capped at $500,000 total across lines |
| Hard money / bridge | Property value, exit plan | Fast acquisition or renovation | Higher leverage cost, short terms |
Inside the DSCR lane itself, there’s real range. Purchases on the strongest files generally reach up to about 75% LTV; refinances and cash-out typically cap lower, around 70% LTV, with roughly six months of seasoning expected before a lender will consider pulling equity back out. A handful of overlay states — Connecticut, Florida, Illinois, and New Jersey — tend to hold purchases closer to that same 75% ceiling but cap loan amounts near $2 million even on otherwise strong files. Credit generally needs to sit around 700 for STR-specific programs, tighter than the 620-660 range that shows up on plain-vanilla long-term rental DSCR files elsewhere in the network. Loan sizes on standard programs run up to roughly $3 million, with select lenders in the network handling smaller balances below that.
Two variations worth knowing about exist for borrowers who don’t clear the standard ratio. Coverage below 1.00 may be available through select lenders in the network, though leverage and terms typically adjust to compensate. Separately, no-ratio structures — where the lender doesn’t measure rent-to-payment coverage at all — may be available through select lenders, generally for borrowers who already own a primary residence. Neither is a fallback that borrowers can count on qualifying for; both are typically subject to tighter conditions than a standard DSCR file. Lendmire’s DSCR loan program for short-term rental properties breaks down how these variations get matched to specific investor profiles.
Term structure follows the same spine across the network: 30-year fixed loans, with 40-year and interest-only periods available through select lenders for investors managing cash flow more actively. Adjustable-rate structures exist too, for investors who specifically want them. Above roughly $2.5 million in loan size, the network generally holds to 30-year fixed only — the exotic term structures thin out at the top of the loan-amount range.
A quick note on entity structuring: many STR investors title these properties in an LLC to separate liability from their personal name and keep the debt off personal credit reports. Whether a given lender will do that depends on program eligibility, so it’s worth confirming case by case.
Where the General Rule Breaks — Edge Cases Every STR Investor Should Know
Unit count changes the form. A single-family STR gets Form 1007. A 2-4 unit property — a duplex or a small multifamily run as short-term units — gets Form 1025 instead, which handles the income differently across units.
The nightly-rate-times-30 mistake. This is the single most commonly flagged error in STR appraisals. Fannie Mae’s own appraiser guidance is explicit that it would be incorrect for an appraiser to take a nightly STR rate and multiply it by 30 to manufacture a monthly rent — Form 1007 is built to document monthly lease comparables, not to convert nightly pricing into a rent estimate. If a file comes in leaning on that math, expect it to get kicked back.
Business-income treatment, as an alternate path. Some lenders classify STR income as business income rather than rental income entirely, which skips the Form 1007/1025 exhibit and applies a different underwriting lens instead. This is a program-by-program decision, not something every lender offers.
Legality is a hard gate, not a soft one. If a property can’t legally operate as a short-term rental where it sits, no lender is going to count that income — the ratio math becomes irrelevant. Some jurisdictions are genuinely restrictive; New York City’s own Office of Special Enforcement requires STR hosts to register and blocks registration outright in rent-regulated and public-housing units, with enforcement aimed at a large pool of unregistered listings. Rules like this vary enormously by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income for any specific address.
Certain property types are simply off the table. Manufactured homes — single- or double-wide — log homes, and barndominiums are not offered under DSCR programs in this network, full stop. That’s not a “harder to finance” situation; it’s outside the box entirely, regardless of how strong the rental income looks on paper.
So Which Structure Fits Your Deal?
An investor buying their first STR with strong personal credit and a clean 12 months of hosting history on a similar property is usually the easiest DSCR file to build — standard purchase leverage, standard documentation, straightforward income math. An investor buying a brand-new-to-market property with zero booking history leans harder on market-data comparables and the appraisal exhibit, and the file usually needs a stronger down payment to offset the uncertainty.
The trickier case is the investor pulling equity out of a property that’s been operating for a while but whose STR income has been inconsistent — strong in peak season, thin in the off months. That’s a DSCR ratio calculated on a full trailing 12 months, seasonality included, so an investor chasing the peak-season number alone is going to be disappointed by what the file actually shows. The stronger move in that scenario is often a smaller cash-out request paired with a longer trailing income window, rather than pushing for maximum leverage on a thin annualized average. Lendmire’s short-term rental financing guide and its breakdown of STR refinance options both walk through how that trade-off plays out in practice.
One thing worth repeating plainly: clearing 1.00 on the DSCR ratio means the rent covers the mortgage payment. It does not mean the property is cash-flow positive. Cleaning fees, management commissions, furniture replacement, utilities, and vacancy between bookings all sit outside that calculation entirely — a file can clear coverage comfortably and still run thin after real operating costs hit the owner’s bank account.
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
Can I get an STR loan on a property with no rental history yet?
Yes, though the underwriting leans harder on the appraisal comparable and third-party market data instead of a trailing income average. Most lenders in the network still expect roughly 12 months of hosting or landlord experience from the borrower generally, even if this specific property is brand new to the portfolio.
Does a DSCR below 1.00 automatically disqualify a property?
No — coverage below 1.00 is available through select lenders in the network, but leverage and terms get adjusted to offset the weaker ratio. It’s not a universal fallback, and it typically comes with lower LTV or a larger down payment than a file that clears 1.00 cleanly.
Is an STR loan the same thing as a second-home loan?
No, and mixing these up creates real risk. A second-home loan assumes personal, occasional use with limited rental activity; an STR/DSCR loan assumes the property is a revenue-generating business. Classifying a heavily-booked rental as a second home to get better terms can create problems down the line if the actual use doesn’t match what was disclosed.
What property types can’t get financed under a DSCR program?
Manufactured homes — both single- and double-wide — along with log homes and barndominiums are not offered under these programs, regardless of how the rental income looks. That’s a property-eligibility gate, not a coverage-ratio issue, so no amount of strong booking history changes it.
Can I refinance an STR once it has an operating history, and does that change the math?
Yes — once a property has real booking history, the refinance runs off that trailing income instead of a market rent guess, which often produces a cleaner file. Cash-out and rate-term refinances on STR properties generally cap around 70% LTV, lower than the roughly 75% ceiling on a purchase, with about six months of seasoning typically expected before the equity pull.
