The Quick Read: Underwriting on short-term rental income suits an operator with documented hosting history on a property that earns well above its long-term rent. The long-term rent fallback suits a property with no history, a thin short-term market, or any doubt about whether short-term use stays allowed. Many portfolio operators run both tests on each property and then pick the structure that fits the file.
- Short-term basis: uses booking history or a market projection, typically with about 12 months of hosting experience and a 640+ credit score.
- Long-term basis: uses a lease or an appraiser’s market-rent opinion, so it needs no platform history.
- On short-term files, purchase leverage tops out at 75% LTV. Refinance and cash-out top out around 70%.
- Both bases are tested against the same idea: does the rent cover the full monthly obligation?
- Clearing the coverage test is not the same as making money. Repairs, vacancy, and management sit outside it.
Here is the honest answer on who each option is for. Short-term underwriting is for the operator who can prove the income and wants the loan sized to what the property really earns. The long-term fallback is for the operator who cannot prove it yet, or who wants the file to survive a rule change. Neither is better in the abstract. The property decides.
This piece compares the two the way a broker sees them across many lenders. Lendmire is a mortgage broker that arranges DSCR financing through select lenders in its wholesale network, across 41 markets including Washington, D.C. For the full background, see the complete DSCR loans guide.
Side-by-Side
The two bases differ mainly in where the income number comes from and how much paper it takes to support it. The table below describes the Lendmire network’s short-term parameters on one side and published industry norms for long-term rent on the other.
| Factor | STR Underwriting | Long-Term Rent Fallback |
|---|---|---|
| Review basis | Booking history or market projection | Lease or appraiser’s market rent |
| Key documents | Platform statements, payout or deposit records | Lease, rent schedule from appraisal |
| Experience expected | About 12 months of hosting | Landlord experience commonly asked |
| Property types | Condos, houses, small multifamily, with exclusions | Same, with exclusions |
| Entity vesting | LLC, subject to program terms | Same pattern under most programs |
| Reserves | Vary by lender, leverage, loan size | Vary by lender, leverage, loan size |
| Timeline | Extra income review steps | Simpler income review |
| Main risk | Variable income, local rules | Lower number on a strong STR |
Network figures for short-term files: purchase up to 75% LTV, refinance and cash-out up to 70%, a 1.00 coverage floor on purchases and on refinances, and a 640 minimum score. The long-term column reflects published industry norms, so a given lender may treat any row differently. Loan amounts run up to $3,000,000 on standard programs. Manufactured homes, log homes, and barndominiums are not offered in these programs under either basis. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
How Each Basis Produces the Income Number
The income number is the whole difference, so it helps to see where each one comes from.
Short-term basis. There are two main inputs. The first is operating history: trailing 12 months of platform statements, payouts, or bank deposits. The second is a market projection from a data tool, used when a property has no record yet. History usually carries more weight than a projection.
Long-term basis. The number comes from an in-place lease or an appraiser’s rent opinion. For a single-family home, appraisers use Fannie Mae’s Form 1007, the Single-Family Comparable Rent Schedule. For two to four units, the report is Form 1025, which Fannie Mae’s Selling Guide describes as the report for two- to four-unit properties. Those are agency forms. DSCR loans are not agency products, but the forms are the common yardstick for market rent.
Some programs reduce short-term revenue before running the ratio. The size of that adjustment is program-specific, so ask before you assume it.
Key Terms Defined
DSCR (debt service coverage ratio): monthly rental income divided by the full monthly housing obligation. A residential DSCR loan usually counts gross rent over principal, interest, taxes, insurance, and HOA dues.
PITIA: principal, interest, taxes, insurance, and association dues. It is the payment side of the ratio.
Trailing 12 months (TTM): the most recent year of actual booking or deposit records for a property.
LTV (loan-to-value): the loan amount as a percentage of the property’s value.
Fallback: using long-term market rent as the qualifying income when short-term income cannot be supported.
Seasoning: the period a lender wants an owner to hold a property before a cash-out refinance. Around 6 months is a common expectation on standard rentals.
When STR Underwriting Is the Better Fit
STR underwriting is the better fit when the property has a clean operating record and the long-term rent would undersell it. Picture a lakefront house with a full year of platform history. Its long-term rent might produce a coverage ratio near 0.9x, while its booking record clears about 1.3x. Underwritten on long-term rent, that property would face lower leverage or a different program. Underwritten on its history, it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
It also fits when you want to hold leverage near the top of the short-term range. A stronger ratio opens better terms and leverage, and the short-term number is often the stronger one in a good vacation market.
Three conditions make it work best:
- Documented history. Statements and deposits that match each other. Messy records slow the file down.
- Experience. About 12 months of hosting is the usual expectation, so a first-time host may not be ready.
- Local permission. 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.
Portfolio operators gain something here. DSCR loans qualify on the property rather than personal income, so there is no personal debt-to-income ratio capping how many properties you can finance. Industry sources describe the same difference from conventional loans. That is why a seasoned operator can keep adding assets as long as each one covers itself.
One more point on the numbers. A strong short-term ratio still says nothing about profit. Cleaning, platform fees, utilities, furnishing, and vacancy all sit outside the calculation. Clearing 1.00 is not positive cash flow.
When the Long-Term Rent Fallback Is the Better Fit
The fallback is the better fit when the short-term number is missing, weak, or at risk. Several situations point that way:
- No history. A new purchase, or a long-term rental you plan to convert, has no booking record. A projection can fill the gap, but the lease or rent schedule is simpler to document.
- A weak vacation market. Where nightly demand is thin, long-term rent can be the higher and steadier number.
- Regulatory doubt. If short-term use might be restricted or lost, a loan that already clears on long-term rent survives that change.
- 2-4 units. Mixed income and a Form 1025 appraisal make a lease-based file easier to document.
Say you own a duplex in a college-area submarket with in-place leases on both units. The leases support a coverage ratio around 1.2x without any platform data. Running that file on long-term rent is cleaner, and you can still convert one unit later if the operating case improves.
The tradeoff is real. On a strong vacation property, the fallback can produce a number too low to clear coverage. If it lands below 1.00, one path is available through select lenders in the network, with leverage and terms adjusted. Another is putting more equity in. Neither is automatic, and each file is underwritten individually.
The Portfolio Operator’s Decision Rule
Treat this as a three-question test, applied to each property.
1. Is there a year of clean history? If yes, the short-term basis is available. If no, the fallback or a projection decides the file.
2. Does short-term use look durable? If permits, HOA rules, or local rules are uncertain, test the fallback first.
3. Does the long-term rent clear on its own? If it does, you have a safety net. If it does not, the property depends on short-term income, and your reserves should reflect that.
Most operators land on a mix. Strong, documented vacation assets run on short-term income. Newer or less certain assets run on long-term rent. Lendmire’s piece Short-Term Rental DSCR Across an LLC Portfolio vs Long-Term covers how that mix plays out when holdings sit in several entities, subject to lender program eligibility.
Two portfolio habits help. Keep one document packet per property, with platform exports, deposit records, the lease, and the rent schedule. And note which assets only clear on short-term income. Those are the ones that need a larger reserve cushion, since reserves commonly run around 6 months of PITIA and vary by lender, leverage, and loan size.
Across the network, one pattern shows up often. Files that pass on both bases get the smoothest review. Files that pass on only one get more questions, and the lender wants to see why the stronger basis is trustworthy.
When Platform History Is the Hinge
Sometimes the choice comes down to what you can prove. Lendmire’s piece Platform History vs Long-Term Lease as DSCR Income Across an LLC Portfolio walks through that call in more detail. The short version: a lease is a signed commitment, while platform history is a record of what happened. Lenders weigh them differently, and a program may prefer one.
Common Mistakes
- Assuming commercial math applies. Commercial lending often uses net operating income over debt service, with 1.25 as a common benchmark. Residential DSCR programs publish their own minimums, so do not carry 1.25 over.
- Treating the rent schedule as paperwork. It can be the coverage figure itself.
- Assuming short-term always wins. In a weak market, long-term rent can be the better number.
- Skipping the second test. Run the ratio both ways before you make an offer.
- Confusing coverage with profit. The ratio tests rent against PITIA only.
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.
The Balanced Verdict
Choose short-term underwriting when the history is documented, the market is strong, and the rules are stable. Choose the long-term fallback when history is missing, the market is thin, or the legal footing is uncertain. If you run a portfolio, use both: underwrite each asset on the basis it can defend, and keep reserves for the assets that lean on short-term income alone.

Frequently Asked Questions
Can a DSCR loan use long-term rent on a property I run as a short-term rental?
Often, yes, depending on the program. Many programs let the borrower choose the basis or will use whichever the file supports. The long-term number usually comes out lower on a strong vacation property, so run both before choosing.
Do I need 12 months of history to use short-term income?
About 12 months of hosting experience is the usual expectation on short-term files. Without it, a market projection or the long-term fallback may carry the file, subject to lender guidelines.
What leverage applies on a short-term rental?
On the strongest files, purchases reach up to 75% LTV, while refinance and cash-out go up to 70%. A 640 credit score is the minimum, and coverage of 1.00 is the floor on both purchases and refinances. Standard rentals have different ceilings. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Does clearing 1.00 mean the property cash flows?
No. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital costs are outside it, so a property can clear coverage and still lose money.
Can an LLC hold these loans?
Many programs allow LLC vesting, subject to program terms. Entity documents are added to the file, and credit and reserves still apply.
