How Lenders Underwrite Airbnb Income (AirDNA vs T12 vs 1007)
By Jaken Finance Group · Principal, Jaken Finance Group
How lenders underwrite Airbnb income on DSCR loans — AirDNA vs T12 vs Form 1007 market rent and which method your file needs. Jaken Finance Group.
How lenders underwrite Airbnb income is the first question to settle before you order an appraisal or bind a contract. DSCR qualification is a fraction — rental income divided by PITIA — but the numerator is not interchangeable. Form 1007 market rent, trailing-12-month platform statements, and AirDNA-style projections can produce three different loan amounts on the same address. Jaken Finance Group originates STR DSCR loans in all 50 states at 5.75%–10.5%; the income method your file uses matters as much as your credit score.
This guide focuses on underwriting mechanics — which document wins, how lenders haircut revenue, and when each method applies. For rate premiums and LTV caps, see short-term rental DSCR loan rates 2026. For the full STR qualification checklist, see DSCR loans for Airbnb.

The three income methods — at a glance
| Method | Source | Best when | Lender trust level |
|---|---|---|---|
| Form 1007 | Appraiser rent schedule | STR not legal, conservative programs, LTR hold | High — standardized |
| T-12 actuals | Airbnb/VRBO/PMS history | Seasoned STR with 12+ months on subject | Highest — proven |
| AirDNA / projection | Market-data model | New acquisition, no subject history | Lower — discounted |
None of these numbers is “wrong.” They answer different questions. The 1007 asks what a long-term tenant would pay. T-12 actuals ask what the property already earned. AirDNA asks what similar listings should earn going forward.
Form 1007 — long-term market rent
The appraiser completes Fannie Mae Form 1007 (Single-Family Comparable Rent Schedule) alongside the appraisal. They compare your property to leased comps and estimate a monthly market rent for a standard 12-month lease — furnished or unfurnished per local norm, but not nightly STR pricing.
How lenders use it:
- Default income figure on standard DSCR programs
- Fallback when STR is illegal, unlicensed, or HOA-banned
- Floor or ceiling in higher-of / lower-of structures
Strengths: Every DSCR lender accepts it. No STR rate add-on on programs that qualify LTR rent only. Appraisal-driven — hard to dispute without your own rent comps.
Weaknesses: Systematically understates strong vacation markets. A Gulf Coast bungalow with $6,000/month STR gross may show a 1007 of $2,800/month. DSCR fails unless you bring more down payment or switch programs.
Deep dive: DSCR loan appraisal and the 1007 rent schedule.
When the 1007 alone is enough: Urban markets where STR and LTR rents converge, or when you intentionally hold as a mid-term / corporate rental near long-term levels. Run the math — if 1007 ÷ PITIA ≥ 1.0 at your target LTV, you may not need STR documentation at all.
T-12 actuals — trailing twelve months on the subject
When the property has operated as an STR for a full year, lenders prefer hard operating history over models. Acceptable sources include:
- Airbnb / VRBO host earnings reports (monthly, 12 consecutive months)
- Property-management statements showing gross bookings and owner disbursements
- PMS exports (Guesty, Hostaway, Lodgify) with booking-level detail
How lenders convert gross to qualifying income:
- Start with gross booking revenue (before owner draws)
- Subtract or factor platform fees, cleaning, supplies, turnover — often bundled as a 20%–35% vacancy and expense load
- Divide by 12 for monthly qualifying income
- Compare to PITIA for DSCR
Example: $84,000 T-12 gross × 70% net factor = $58,800/year = $4,900/month qualifying.
Documentation standards lenders enforce:
| Requirement | Why |
|---|---|
| Address matches appraisal | Prevents using another property’s history |
| No gaps > 30 days without explanation | Lenders fear hidden downtime |
| Permit number on application if required locally | Unlicensed income excluded |
| Consistent listing count | One listing per financed unit |
Seasonality handling: Lenders annualize the trailing 12 months — they do not annualize peak summer alone. A Smoky Mountain cabin must show November–February in the T-12, not just June–August exports. Gatlinburg operators: Gatlinburg STR loans 2026.
T-12 is the strongest STR income path. It usually earns the best STR pricing tier when DSCR clears 1.25+ after the expense factor.
AirDNA and STR projections — modeled income
On acquisitions — especially new builds or conversions with no STR history — lenders accept third-party STR analytics. AirDNA Rentalizer is the most common; some underwriters also review AllTheRooms, Mashvisor, or comp-set spreadsheets from a local STR manager.
Typical workflow:
- Borrower orders report keyed to exact address
- Report shows projected annual gross, ADR, occupancy
- Lender applies 10%–25% haircut on gross (deeper than T-12)
- Same 20%–35% operating load may apply after the haircut
- Result is qualifying monthly income
Example: AirDNA projects $92,000 annual gross. Lender takes 15% projection haircut → $78,200. Applies 30% expense factor → $54,740/year = $4,562/month qualifying.
Why the haircut exists: Projections assume optimal listing performance from day one. Lenders know ramp-up takes 3–9 months — photos, reviews, pricing algorithm tuning. The discount buys conservatism.
When AirDNA is required vs optional:
| Situation | Typical method |
|---|---|
| Subject operated STR 12+ months | T-12 actuals — AirDNA supplemental |
| Subject never listed | AirDNA or PM pro forma |
| Seller-operated STR, buyer needs proof | Request seller statements via addendum |
| Refi after you operated 12 months | T-12 replaces projection at refi |
AirDNA without legal STR status is worthless for underwriting — if the city bans nightly rentals, the lender stops at the 1007. Check Peoria, Chattanooga, and other city guides on short-term rental laws for investors.
Higher-of, lower-of, and STR-only — program logic
Underwriting method and program structure are linked:
| Program type | Income rule | Borrower impact |
|---|---|---|
| LTR only | 1007 | Lowest rate if DSCR clears; may fail in vacation markets |
| Higher-of | max(1007, STR documented) | Best leverage on performing STR; STR rate add-on |
| Lower-of | min(1007, STR documented) | Safer for lender; less premium than higher-of |
| STR-only | T-12 or AirDNA only | Used when 1007 is irrelevant to operator intent |
The DSCR loans for Airbnb hub covers qualification strategy; this section is the document-level view. Ask your loan officer: “Which line on the rate sheet applies to my income method?” before appraisal payment.
Side-by-side — same address, three numerators
Property: 4-bed vacation rental, Destin market · PITIA (estimated): $3,600/month
| Method | Gross / source | After lender adjustments | Monthly qualifying | DSCR |
|---|---|---|---|---|
| 1007 | Appraiser | None | $3,200 | 0.89 |
| T-12 actuals | $96,000 gross | −30% expense | $5,600 | 1.56 |
| AirDNA | $88,000 projected | −15% haircut, −30% expense | $4,340 | 1.21 |
At 75% LTV, only T-12 and AirDNA clear standard 1.0+ DSCR — but AirDNA sits near the pricing cliff. A 0.25% rate move or higher expense assumption drops it below 1.20. Destin-specific context: Destin STR loans 2026.
Mid-term and corporate rentals — hybrid underwriting
Some operators run 30+ day furnished stays (travel nurses, insurance relocations). Lenders may:
- Treat as long-term furnished on the 1007 if comps support it
- Request lease agreements if tenants stay 30+ days consistently
- Still classify as STR if average stay under 30 days
If your average stay exceeds 30 days and you have executed leases, ask whether the file can avoid STR add-ons while keeping above-market rent. Mid-term rental DSCR loans may fit.
Appraisal coordination — avoid conflicting numbers
Order of operations matters:
- Confirm STR legality and permit path at the address
- Choose income method with lender before appraisal
- Deliver T-12 or AirDNA to appraiser when the program allows STR addenda
- Reconcile 1007 vs STR docs before conditions clear
Appraisers do not always attach STR revenue to the 1007. Some lenders use Form 1007 for LTR and a separate STR income worksheet for DSCR — two documents, one DSCR calculation. Miscommunication here is a top reason STR files miss closing dates.
Red flags that force a method downgrade
| Red flag | Lender response |
|---|---|
| No STR permit where required | 1007 only or decline |
| HOA prohibition on STR | 1007 only |
| Material 1007 vs T-12 mismatch | Extra review, lower-of treatment |
| AirDNA comps from different submarket | Reject projection — order new report |
| Seller statements show off-platform cash | Excluded from qualifying |
Insurance gaps can also stall the file — see STR insurance, permits, and financing.
Decision tree — which method should you bring?
- Is STR legal with permit in hand (or obtainable pre-close)? No → plan on 1007 only. Yes → continue.
- Does the subject have 12 months STR history? Yes → lead with T-12 actuals. No → order AirDNA.
- Does 1007 ÷ PITIA ≥ 1.0 at target LTV? Yes → consider LTR program for lower rate. No → need STR-friendly higher-of.
- Are you buying in an HOA or condo? Yes → read Airbnb HOA and condo financing before relying on AirDNA.
- Refi in 12 months? Operate cleanly, keep PMS records — refi on T-12 usually beats purchase pricing on AirDNA.

Bottom line
AirDNA, T-12, and the 1007 answer different underwriting questions. Trailing actuals win when you have them; AirDNA bridges acquisitions; the 1007 remains the fallback when STR income cannot be used or when it alone clears DSCR at a lower rate. Match your documentation to your lender’s program before inspection ends — the income method is not something you fix after the appraiser visits.
