Can Airbnb Income Qualify You for a Mortgage?

Airbnb and other short-term rentals have become a popular way for California homeowners to generate extra income — but that income doesn’t always count the way people expect when it’s time to buy or refinance. Here’s how Fannie Mae and Freddie Mac guidelines treat short-term rental income, and what it takes to get it counted toward your loan.

What counts as short-term rental income?

Short-term rental income includes any rental activity where guests stay for days or weeks rather than under a traditional 12-month lease — Airbnb, Vrbo, and similar platforms all fall into this category. Fannie Mae and Freddie Mac both allow this income to be used for qualifying purposes, but only when it’s documented the right way.

How do lenders calculate Airbnb income?

Short-term rental income must be documented through your federal tax returns — specifically Schedule E — not through a booking platform summary or a lease. Lenders start with the net rental income (or loss) reported on Schedule E, then add back certain expenses the IRS lets you deduct but lenders don’t count against you, like depreciation, mortgage interest, property taxes, and HOA dues. The result is annualized by dividing the total by 12, assuming the property was rented for the full prior year, then netted against the property’s full monthly payment (PITIA) to determine how much can be added to your qualifying income.

If the property was purchased or converted to a rental partway through the year, the calculation is prorated based on the number of days it was actually in service.

What if you just started renting on Airbnb?

This is where short-term rentals differ most from traditional rentals. For a standard long-term rental with no tax history yet, lenders can often use a current signed lease — multiplied by 75% to account for vacancy and expenses — to estimate income. Airbnb rentals don’t have that option, because there’s no lease agreement to point to.

In practice: if you don’t yet have a tax return showing the short-term rental activity, that income generally can’t be used to qualify. A history of bookings isn’t the same as a documented history — even strong Airbnb earnings won’t help your application until they show up on a filed tax return. One year is often the minimum, and two years is stronger, especially if any single year shows fewer than 365 rental days on Schedule E.

Why doesn’t a lease agreement work for short-term rentals?

For traditional rentals, a signed lease is one of the strongest documents you can provide. For Airbnb-style rentals, it isn’t accepted as a substitute for tax return history. Guests don’t sign a lease the way a long-term tenant would, so there’s nothing for the lender to point to as proof the income will continue. That’s why the tax return — not the booking calendar — is what carries the weight in underwriting.

What documentation will you need?

If your short-term rental income does have tax return history behind it, be ready to provide complete federal tax returns — including Schedule E — for the most recent year, with two years often preferred for short-term rentals specifically. Submit all schedules and pages, not just the summary pages, and document any non-recurring expenses you’re asking to have added back, such as a paid invoice for a one-time repair.
