The Quick Read: Platform history is the stronger evidence when the property already operates, and AirDNA is the fallback when it does not. Across the wholesale network, short-term-rental income is documented through twelve months of operating history on a refinance or the appraisal’s short-term-rent analysis on a purchase, counted at 80% of gross. A market-data report supports that analysis but is not the qualifying document by itself.
- Short-term-rental files run to $2,000,000 through select programs, subject to underwriting. Above that, the deal works to a long-term rent schedule.
- A refinance of an operating rental leans on platform and bank records. A purchase leans on the appraisal’s rent analysis.
- Coverage of 1.00 or higher is required on short-term-rental files.
- Permit evidence is documented for the specific property. Rules are set locally and change.
- Family office vesting works through LLCs, with no layered entities.
The Honest Answer: Who Each Path Is For
Platform history is for the owner who has run the property. AirDNA is for the buyer who has not. That is the whole split, and everything else is detail.

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.
Platform history means payout and earnings exports from Airbnb, Vrbo or a property-management system, reconciled to bank deposits. It shows what this property actually earned. A market-data projection shows what comparable properties earned nearby. It is a model, not a record.
For a family office, a third fact decides the file before either document does: loan size. Short-term-rental income only works to $2,000,000 in the programs the network places. Past that, neither document is the qualifying basis. Most family office super jumbo files above that line are underwritten on long-term rent, with two appraisals. For the wider mechanics, see the complete DSCR loans guide.
Side-by-Side
The column for AirDNA-style projections reflects published industry norms. Lendmire’s wholesale network places files on both paths.
| Factor | Platform History | AirDNA-Style Projection |
|---|---|---|
| Review basis | Actual operating income | Modeled market income |
| Typical use | Refinance of operating STR | Purchase or conversion, no history |
| Documentation | Platform exports, bank deposits | One report plus appraisal support |
| Property types | Any eligible 1-4 unit STR | Same, with comp-matching limits |
| Entity vesting | LLC or revocable trust | Same, no change by income type |
| Reserve expectation | Same program reserves | Same program reserves |
| Main failure mode | Gaps, mixed income, commingled deposits | Overstated address-level estimate |
| Timeline | Depends on record cleanup | Depends on appraisal scheduling |
Reserves do not change with the income document. In the network, reserves run 6 months of PITIA on the subject property, and 12 for first-time investors, subject to underwriting.
When Platform History Is the Better Fit
Platform history wins on any operating property. It is a record, so an underwriter can test it against deposits. On a refinance, the network’s programs count twelve months of operating history at 80% of gross, with coverage of 1.00 or higher.
AvantStay, an STR operator, says actual history of 12 to 24 months carries more weight than projections. That matches what files show. A clean record shortens the questions an underwriter asks.
Three things make history clean:
1. Platform payout exports for the full twelve months, in the property’s name or the entity’s name.
2. Bank statements that tie each payout to a deposit.
3. Separation of income from other rentals the entity owns.
Commingled deposits are the usual problem. A family office that routes several properties through one operating account has to separate them line by line. That is tedious but fixable. A missing month is harder.
Whose history counts is program-specific. Some programs accept history from other short-term rentals the borrower owns. Others want the subject property only. Confirm that before choosing a path.
History also helps on experience. Short-term-rental files in the network are for experienced investors, meaning twelve months owning income property in the last thirty-six. Operating records for the subject double as proof of that.
When AirDNA Is the Better Fit
AirDNA fits a purchase with no history, or a long-term rental being converted. There is nothing to export, so the appraisal’s short-term-rent analysis carries the income, at 80% of gross. A market-data report built from comparable short-term rentals supports that analysis.
VaultSTR reports that market-level data is reliable and widely used by lenders, while address-level projections can run well off actual results, with misses clustering high. Treat the figure as a first estimate. It is not an underwriting number.
BnBCalc adds that comp matching leans on distance more than on amenities. That matters for luxury property. A high-end house with few true comps is the case where a projection is least reliable. Family office assets often sit in that category.
The practical approach: run the report, then haircut your own expectations before the appraiser does. If the projection only works at full gross, the file is fragile. Underwriters apply their own discount, and the appraisal can land lower than the report.
The appraisal also has a second job. Above $2,000,000, two appraisals are required. Both feed the rent figure, so a short-term-rent analysis that diverges between them raises questions.
How Loan Size Changes the Answer
At super jumbo size, this comparison may be moot. The size ladder in the network sets the limits, all subject to underwriting:
| Loan Size | Purchase Leverage | Cash-Out |
|---|---|---|
| $150K-$1M | 80% | 75% |
| $1M-$1.5M | 75% | 70% |
| $1.5M-$2M | 75% | 60% |
| $2M-$3M | 75% | 60% |
| $3M-$4M | 65% | — |
| $4M-$6M | 60%, on review | — |
| $6M-$10M | 60%, on review | — |
The top cell in each band needs a stronger score as size grows: 660 or better at the first band, 700 for the next, and 720 for the $1.5M-$3M bands. The program floor is 660 on loans to $3,000,000, and 700 above that.
Short-term-rental files stop at $2,000,000. Above $3,000,000 the super-jumbo overlay applies: 0x30x24 housing history, citizens and permanent residents only, and no rural property. Above $4,000,000 every request is reviewed case by case before submission, on purchase or rate-and-term only.
Think about what that means for a family office buying a $5,000,000 coastal house that runs well on Airbnb. The STR income path is closed at that size. The property is underwritten on a long-term rent schedule, with two appraisals. A house that only works on nightly income may fall short on paper, even with excellent records.
Two options exist. Restructure so the loan sits at or below $2,000,000, with more equity in the deal. Or accept a long-term-rent test and size the loan to it, through select programs that allow reduced coverage (LTV and terms adjust, subject to underwriting). Platform history and AirDNA both still help, as supporting evidence of property quality. They just do not set the coverage figure.
Family Office Entity Questions
Entity questions do not change with the income document. The same vesting rules apply to platform history and to AirDNA.
LLC vesting is welcome, subject to program terms. Layered entities are not. A holding company owning an LLC that owns the property is a common family office structure, and it creates friction. Flatten it before the file goes in, or expect questions.
Revocable trusts generally work. Irrevocable trusts create friction, mainly around guarantor requirements. An LLC also does not necessarily remove personal liability, because lenders typically want a guarantor behind the entity.
Family office files carry more entity paperwork: operating agreements, certificates of good standing, authority resolutions. These are not income documents, but a missing one stalls the file the same way a missing payout export does.
When the Two Disagree
Disagreement is common on a refinance. Actual results come in below the projection, or well above it. How programs treat that varies. Some take the higher figure. Others take the lower of the available figures. Ask the program before assuming.
Assume the lower. A file built on the lower number clears either way. A file built on the higher one can fail when an underwriter picks the other.
If actuals run far above the market model, expect questions about why. A documented reason helps: a renovation, a new management company, a premium location. If actuals run below the model, the record usually governs. A projection does not override a year of real results.
The same discipline applies to the 1007 rent schedule. It is a long-term market rent estimate, and it often sits well below short-term potential. It matters because it is the fallback when short-term income is not available.
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.
Documentation Checklist for a Large STR File
- Twelve months of platform payout and earnings exports, or manager statements.
- Bank statements reconciling those payouts to deposits.
- Permit or license evidence for the specific property.
- Entity documents, with vesting flattened to a single layer.
- Reserve documentation: 6 months of PITIA on the subject property, with cash-out proceeds never counted toward it.
- Appraisal access, including the second appraisal above $2,000,000.
- For a purchase, a market-data report to support the appraisal’s rent analysis.
On permits: municipal permission to operate a short-term rental is documented property by property. 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.
Where This Goes Wrong
Three failure modes show up most.
First, an overstated projection. The investor shows a market report at full gross, and the appraisal analysis lands lower. Coverage falls below 1.00. Pre-empt it by running the number at 80% of a conservative estimate.
Second, a file that assumes the STR path at a size where it does not exist. This is the most expensive mistake, because it surfaces late.
Third, mixed deposits. Records exist but cannot be separated by property. The fix is slow and dull. Start early.
Interest-only is an option worth knowing on large files. The network offers a 120-month interest-only period on 30- and 40-year terms, up to 75% leverage, qualified on interest, taxes and insurance, subject to underwriting. It improves coverage on paper without changing the income evidence. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Decision Flow
- Operating property, loan at or under $2,000,000: platform history.
- Purchase with no history, loan at or under $2,000,000: the appraisal’s STR analysis, supported by a market report.
- Any loan above $2,000,000: long-term rent schedule, two appraisals, supporting STR evidence.
- Coverage under 1.00 on long-term rent: select programs in the network review 0.75 to 0.99 at reduced leverage (LTV and terms adjust, subject to underwriting). Short-term-rental files themselves need 1.00 or higher.
A Balanced Verdict
Platform history is better evidence. AirDNA is better than nothing. Neither fixes a loan that is too large for the STR path. For a family office, size and entity structure decide the file before the income document does. Pick the income path by transaction type, test it at the lower of the available figures, then check the loan size against the ladder.

Frequently Asked Questions
Does AirDNA replace platform history?
Only when no history exists, such as a purchase or a conversion. Then the appraisal’s short-term-rent analysis carries the income, supported by a market report. On an operating property, the record of what it earned is stronger evidence.
What if the projection falls short of 1.00?
Short-term-rental files need coverage of 1.00 or higher, so a shortfall sends the file to other paths. Options include a lower loan amount, a long-term rent test, or select programs that review 0.75 to 0.99 at reduced leverage. LTV and terms adjust, subject to underwriting.
Does the entity matter?
Yes, for vesting, not for income. LLCs and revocable trusts generally work, and layered entities do not. The same rules apply whether the income comes from platform history or a projection.
Does the STR path scale to the largest balances?
No. Short-term-rental files stop at $2,000,000 in the network. Above that, the file is underwritten on a long-term rent schedule with two appraisals, and above $3,000,000 the super-jumbo overlay adds its own credit and borrower requirements.
Why is STR income counted at a discount?
Because the coverage test compares rent to the monthly obligation and ignores operating costs. Short-term rentals carry cleaning, management, platform fees and vacancy, so income is counted at 80% of gross in the network’s programs.
