Airbnb / Short-Term Rental Income — Fannie Mae
Agency rental-income rules, DSCR math and real-world investor financing without mixing them into one generic rule.
STR has its own Fannie topic
Fannie now separates subject-property short-term rental income from ordinary long-term rental analysis.
Tax history matters
Schedule E and Fair Rental Days can be relevant to documenting short-term-rental history under current policy.
Do not use Airbnb projections as automatic income
Projected nightly rates, occupancy calculators or host dashboards are not automatically equivalent to agency qualifying income.
Property eligibility is separate
Even when income is documentable, condo/project restrictions, zoning, insurance or property use can independently affect mortgage eligibility.
Investor underwriting checklist
Identify occupancy, unit count, purchase/refinance/cash-out purpose, current ownership/title, financed-property count, current PITIA on every retained property, leases, Schedule E history, acquisition dates, reserves, entity ownership, short-term-rental use, condo/project status and the exact agency or private-investor program. Rental income should be calculated only after the property is placed in the correct underwriting category.
Where experienced analysis matters
A deal can fail because the wrong rent document was used, positive rental income was treated too generously, reserves were calculated incorrectly, an LLC mortgage was counted incorrectly, a newly acquired rental was analyzed under an older rule, or a private DSCR overlay was presented as if it were a Fannie/Freddie requirement.

How I would underwrite the scenario step by step
1. Identify agency conventional versus private DSCR/portfolio financing. 2. Build a complete real-estate-owned schedule with ownership, mortgage obligation, PITIA, rent, acquisition date and entity vesting. 3. Determine the permitted rental documentation for each property. 4. Calculate each rental separately under the applicable rule. 5. Count financed properties and calculate required reserves. 6. Review property/project eligibility, LTV, credit and cash-out/seasoning. 7. Only then compare pricing and decide which loan structure best fits the investor's strategy.
This sequence prevents a strong-looking property from being qualified with the wrong income methodology. For investors with several rentals, one incorrectly treated property can change DTI, reserves, financed-property count or even product eligibility.
