The Quick Read: Document each property’s income by its type, tie it to bank deposits, and roll every property into one consistent schedule. Mid-term stays run more than 30 days but less than a year, and no standard data tool exists for them, so underwriters lean on records they can verify. Treatment varies by program, and qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines.
- Executed leases plus proof of payment are the core evidence for mid-term units.
- Nightly properties are proven by platform history and deposits, usually about 12 months of it.
- Furnished premiums do not automatically count. Underwriters generally start from appraiser market rent or an eligible lease.
- A blanket loan tests the pool together. Separate loans test each property alone.
- Clearing 1.00 on coverage is not the same as positive cash flow.
Most investors with a mixed portfolio get tripped up in one place: they hand over a pile of statements instead of a package. This guide shows how to build the package.

Key Terms Defined
DSCR (debt service coverage ratio) is the property’s rent divided by its monthly obligation. That obligation is PITIA: principal, interest, taxes, insurance, and any association dues.
Mid-term rental is a furnished stay of more than 30 days but under a year. It sits between nightly and standard long-term leases.
Qualifying income is the rent figure an underwriter actually uses. It can differ from what you collect.
Trailing history is the look-back window of past income records, often 12 months.
Haircut is a reduction applied to gross income before the ratio is run.
Blanket loan is one loan secured by several properties and tested as a pool.
How Does Underwriting Treat Mid-Term Income?
Underwriting treats mid-term income by asking one question: can the lender verify it from a third party? Without an AirDNA-style tool for 30-plus-day stays, the answer rests on executed leases, management statements, deposit history, and the appraiser’s rent opinion.
That gap is the whole story. A nightly property has a data feed. A mid-term property has paper.
No regulator or government body sets a standard for this. It is a private-market practice. Across the wholesale network Lendmire works through, some programs treat a furnished 30-plus-day rental as a long-term rent file. Others treat it as a short-term file when the evidence points that way. Same property, different path, different coverage figure.
The practical rule: a furnished-rental premium does not automatically count. Many underwriters start from the appraiser’s market rent, then credit more only when documents support it.
Step by Step: Building the File for Each Property
Work through five steps, in order, for every property.
1. Classify by stay length. Label each property nightly, mid-term, or long-term. Each label sends the file down a different documentation path. A property that mixes stay lengths gets the label its actual bookings support.
2. Set the appraisal baseline. The appraiser produces a market-rent opinion. Single-family homes use a comparable rent schedule (form 1007). Two-to-four-unit properties use an operating income statement (form 1025). Lendmire’s complete DSCR loans guide explains both. Treat this number as your floor for planning.
3. Pick the evidence.
| Property type | Primary evidence | Supporting evidence |
|---|---|---|
| Leased mid-term unit | Executed lease | Proof of payment |
| Operating mid-term | Management statement | Trailing deposits |
| True nightly STR | Platform history | Deposits, market report |
| New or vacant | Appraiser rent opinion | Market data |
4. Expect a haircut. Lenders typically apply an expense factor to gross short-term income because operating costs run higher than for long-term rentals. That is a market-wide survey figure, not a rule in the network. Programs differ, so ask what your program uses.
5. Run the test. Divide rent used for lender review by PITIA. Then see which structure the loan uses, covered below.
What the Network’s STR Programs Expect
For properties underwritten as short-term rentals, the network’s programs generally allow purchase leverage up to 75% LTV (loan-to-value, the loan as a share of the price) on the strongest files. Short-term refinances and cash-out refinances top out around 70% LTV. Expect a credit score of 640 or higher and about 12 months of hosting history.
Coverage on a short-term purchase starts at 1.00 on select programs, and the same is true on refinances. Stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Standard loan sizes run up to $3,000,000. Reserves vary by lender, leverage, and loan size, commonly around six months of PITIA. All of this is subject to lender guidelines and individual underwriting.
One note on eligibility: manufactured homes, log homes, and barndominiums are not offered in these programs.
Separate Loans or One Blanket Loan?
The structure decides how one weak property affects the rest. Separate loans test each property on its own rent against its own PITIA. A blanket loan tests the whole pool together, though Lendmire’s blanket page notes each property still gets its own appraisal and market-rent opinion.
In a pooled test, a strong property can carry a weak one. That helps when one mid-term unit has thin paperwork. It hurts when you wanted that strong property’s coverage to stand alone.
A mixed portfolio can also split across lenders. So your nightly properties and your mid-term properties may end up in different loans. Plan for that early rather than discovering it mid-file.
The Portfolio Schedule That Makes Underwriters Happy
Build one schedule. Give every property a row with these columns:
- Stay-length classification
- Income evidence type
- Trailing deposits or lease terms
- PITIA
- Permit or compliance status
Keep mid-term properties in a separate documentation column from true STRs. Don’t blend them in one trailing number.
Then reconcile. Match platform payouts and management statements to bank deposits, month by month. If a manager covers several units, or properties sit in different LLCs, separate the deposits by property before you submit. LLC-titled borrowers are fine on many files, subject to program terms, but commingled accounts force the underwriter to guess. Underwriters don’t like guessing.
A practitioner observation: files stall most often on mismatches. A payout that doesn’t match a deposit, a missing month, or a property that switched from nightly to monthly with no note. A one-paragraph explanation per property, attached to the schedule, answers the question before it is asked.
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.
Worked Example: Three Properties, Three Paths
Run the numbers on a hypothetical portfolio. Every input here is a modeled assumption, not market data.
- Property A, a mid-term unit under an executed lease. Rent supported by the lease and payment proof. Coverage clears roughly 1.25x.
- Property B, a nightly STR with a full year of platform history. After the expense factor, coverage lands near 1.10x.
- Property C, a recent mid-term conversion with only a few months of deposits. The underwriter falls back on appraiser market rent. Coverage comes out near 0.95x.
On separate loans, A and B each clear 1.00. C sits below it. Sub-1.00 coverage is available through select lenders in the network, with leverage and terms adjusted, so C is a conversation rather than a dead end. Qualification stays subject to lender guidelines, credit approval, and property review.
On a blanket loan, the pooled ratio sits comfortably above 1.00 because A and B carry C. Same three properties, different outcome. That is why structure choice belongs in your planning.
Notice what moved the number. Not the properties’ real performance, but how each was proven. The same revenue can produce different ratios depending on whether it is proven, projected, or lease-based.
Where the General Rule Breaks
Rent-by-the-room. Some investors compare a long-term estimate against a room-by-room total. Expect the appraiser’s rent figure, not your room total.
Lease required before purchase. Many lenders may require the property to be leased before purchase, while a handful will not. Ask early.
Seasonality. A three-month snapshot taken at peak season flatters the numbers. Twelve months smooths it, which is why most nightly programs ask for that much history.
Tax classification. The IRS covers rental reporting on Schedule E, and short-term rentals can land on Schedule C per the University of Illinois Tax School. Tax tests like the 7-day and 30-day averages govern how income is taxed, not which lending category a stay falls into. A 30-day stay does not change lending treatment because of them. 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.
Three Myths Worth Dropping
“Furnished rent counts at the full premium.” Not automatically. Underwriters generally use appraiser market rent or an eligible lease.
“AirDNA works for mid-term.” It covers short-term data only, so lenders don’t underwrite mid-term rentals to it.
“DSCR means no paperwork.” Your personal income isn’t the test, but the property’s income evidence is.
What If the Combined Ratio Falls Short?
You have four levers. Strengthen the evidence on the weakest property. Carve it into a separate loan or move it to a blanket pool. Lower leverage so the payment shrinks. Or look at a select-lender path for sub-1.00 coverage, where leverage and terms adjust. A larger down payment can lift the ratio, but it never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
One caution on reading the result. Repairs, vacancy, management, utilities, and capex sit outside it. Clearing 1.00 is not positive cash flow.

Frequently Asked Questions
Will a lender count mid-term rental income?
Often yes, but treatment varies by program. Some programs underwrite a furnished 30-plus-day rental on long-term rent. Others use short-term evidence. Executed leases and deposit history give you the strongest footing either way.
Which documents prove mid-term income?
Executed leases, proof of payment, third-party management statements, and trailing bank deposits. For a new or vacant unit, the appraiser’s rent opinion fills the gap.
Can strong properties offset weak ones?
Only under a pooled structure like a blanket loan. On separate loans, each property is tested alone against its own PITIA.
Do I need a lease before I buy?
It depends on the lender. Many may require one, and a handful will not. Ask before you write the offer.
Does a 30-day stay change my loan category because of tax rules?
No. Tax tests decide how income is reported. Lending treatment follows the program’s own rules and the evidence you provide.
