"Can Nightly Rental Income Help Me Qualify to Buy a Short-Term Rental?"

By Jeff Moran, NMLS #483943 · September 25, 2026

Yes, on a one-unit investment property, and the calculation begins by cutting the gross rent in half. Fannie Mae's short-term rental section lets nightly income reach your application, as long as the property is legally permitted to operate that way and your current housing payment is documented. The file needs either an appraiser's rent schedule or validated data on three comparable short-term rentals nearby.

I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, originating since 1996, NMLS #483943, through C2 Financial Corporation, licensed in fifteen states.

The cottage you have been watching for two summers finally came on the market, and the listing agent has a page of what it grossed last year on a nightly platform. You would like to know whether any of that helps you buy it, or whether you are qualifying on your own paycheck alone and the rental income is just something you hope for later.

There is an answer now, and it is more specific than it used to be. Fannie Mae rebuilt its rental income rules on September 2, 2026, and short-term rentals came out of that with a section of their own: B3-3.8-03, Rental Income from the Subject Property: Short-Term Rental, revised 09/02/2026. Lenders may use it right away and have to use it for applications dated on and after November 1, 2026 (Announcement SEL-2026-08, September 2, 2026).

Which properties can use nightly income in the first place?

One-unit investment properties, and nothing else.

Fannie Mae's section names the eligible property type in one line: one-unit investment properties only. A home you are going to live in cannot use nightly income from itself to qualify, and neither can a second home you keep available to yourself. If you are still deciding which of those two the purchase actually is, the difference between a second home and an investment property is worth settling before anything else, because it decides which rulebook you are even reading.

The property also has to be legally permitted to operate as a short-term rental, and the guide spells out what that includes: compliance with all applicable local registration and licensing requirements. Plenty of towns cap nightly rentals by district, require an annual permit, or tie the permit to the seller rather than to the property. Please ask the municipality and the association early. Whether a lender would count the income does not matter yet, because none of it applies until the town has said the property can be rented by the night.

One more line in that section matters if you are looking at a home with an apartment on it. Short-term rental income cannot be derived from an accessory dwelling unit. Rent from a garage apartment or a basement unit runs on a different section entirely, on a longer lease, with its own discount and its own cap. Rent from an accessory dwelling unit covers that path.

What counts as proof that the nightly income is real?

On a purchase, you have two acceptable sources and the file uses one of them.

The first is the Single-Family Comparable Rent Schedule, Form 1007, completed on a standard long-term basis. That is the appraiser's opinion of what the property would bring in on an ordinary twelve-month lease, which is usually a more conservative figure than a good nightly season produces. It has to be ordered as part of the appraisal assignment, and it does not get added automatically. Please raise it before the appraisal is scheduled, along with everything else the appraisal is being asked to do.

The second is validated rental data for other short-term rentals, and the guide is specific about where it comes from and what it has to contain. It comes from a multiple listing service or from property management companies. It has to cover three comparable short-term rental properties, and those comparables should be from within the same market area as the property you are buying, including the same subdivision or project where possible. For each one, the data has to show daily, weekly or monthly rental rates, and the number of days rented in the last calendar year, plus any relevant factors that could affect the property's use as a short-term rental. Your lender keeps all of that in the file.

The seller's own earnings history is not on either list. A screenshot from a booking platform showing what this property grossed is a useful thing to look at while you are deciding whether you want to own it. It is not one of the two sources the guide names on a purchase. The comparables come from a multiple listing service or a property manager, and they cover other properties.

How does the lender turn that into a number?

Through a fixed calculation, and half the gross rent comes off the top before anything else happens.

The lender picks one of the two sources above. From there, the lender multiplies the monthly gross rental amount by 50 percent, and the guide says plainly what the missing half is for: vacancy losses and maintenance expenses. That produces the net rental income. The lender then subtracts the full monthly payment on the property, meaning principal, interest, taxes, insurance and any association dues. What is left is called adjusted net rental income.

Where you take the validated-data path, there is one more step before the 50 percent. The lender averages the daily, weekly or monthly rate across the three comparables, then multiplies that average by the average number of days those same comparables were rented. An average nightly rate multiplied by an average of 180 nights is a very different annual figure than the same rate multiplied by 300, which is why the days-rented column matters as much as the rate column.

Then the result decides what happens to your ratio. If the adjusted net rental income is positive, the lender may use the rental income to offset the payment on the property. If it is negative, that amount goes into your debt-to-income ratio as an obligation. Both of those come straight out of B3-3.8-03.

A strong result keeps the new property from weighing on your ratio, but it does not become income the file can count toward anything else.

What does this look like with numbers?

Numbers below are made up to show the mechanism. Yours will land somewhere else.

Three comparable short-term rentals in the same market area, pulled from the multiple listing service:

Comparable A      $240 / night      180 nights last year
Comparable B      $210 / night      150 nights last year
Comparable C      $270 / night      210 nights last year
                 -----------       --------------------
Average           $240 / night      180 nights
Average nightly rate                        $240
Average nights rented                        x 180
                                        ----------
Gross rent for the year                  $43,200
Divided by twelve                            / 12
                                        ----------
Monthly gross rental amount               $3,600

Vacancy and maintenance factor              x 0.50
                                        ----------
Net rental income                         $1,800 / mo

Full monthly payment on the cottage       $2,150 / mo
                                        ----------
Adjusted net rental income                 -$350 / mo

That one comes out negative, and the $350 joins your monthly obligations. The property is still buyable. You are simply carrying $350 a month of it on your ratio rather than none of it.

The same property can land on the other side of that line. If a larger down payment brought the monthly payment down to $1,750 instead, the adjusted net rental income would come out positive by $50, and the rental income would offset the payment rather than adding anything to your obligations. How much you put down is what moves it from one of those outcomes to the other, so this arithmetic belongs in the conversation before you decide how much cash to bring to the closing.

What has to be true about you, and not about the property

Two things. The first is your own current housing payment, which the lender has to document before any rental income from the property counts. That cost can be rent, a full mortgage payment, or just the property taxes on a home you own outright. Acceptable proof includes direct verification of rent from a management company, six months of bank statements or cancelled checks showing the payments, or evidence you paid the latest property tax bill (B3-3.8-01, General Rental Income Information, revised 09/02/2026). None of that is difficult to gather. It just takes a few days when you are starting from nothing.

The second is your history as a landlord, which conventional financing measures in twelve-month terms and documents through tax returns. Whether you have that history changes how positive rental income can be used across Fannie Mae's rental sections. Whether rental income counts when you buy another property walks through how that history gets established and what the file wants to see.

If you have rented anything out before, this is the moment to say so. When you're ready, please provide your complete income tax returns, all pages and schedules, please. We will need the past two years for your personal and for any business that you may have an interest in.

Where this gets missed

Counting on nightly income for a property you will occupy. The section is written for one-unit investment properties. A buyer planning to live in the home half the year and rent it the other half is asking a different question, and the answer to that one does not come from B3-3.8-03.

Treating the seller's booking history as the documentation. It tells you about the property. On a purchase, the file is built from an appraiser's rent schedule or from validated data on three other short-term rentals.

Leaving the permit question until after the offer. A property that cannot legally be rented by the night in its own town is not a candidate for this section at all, no matter how good the comparables look.

Forgetting that the payment includes everything. Taxes and insurance on a coastal or mountain property are frequently the two largest numbers in that payment, and the whole payment is what gets subtracted. What happens to property taxes after you buy is worth reading before you estimate them from the seller's current bill.

Leaving reserves until the end of the planning. Investment property purchases carry their own reserve expectations, and reserves are money still in your accounts after every closing cost and down payment dollar is spent. What counts as reserves covers where those dollars can come from.

What to do before you write the offer

You want to start with the town, ahead of everything else. Please ask the municipality whether short-term rentals are permitted at that address, whether a registration or a license is required, and whether it transfers to you or has to be applied for fresh. An association can have its own rules on top of the town's.

Then you can ask the listing agent or a local property manager what three comparable short-term rentals in the same area did last year, by nightly rate and by nights rented. That is the same shape as the data the file will need, so you get to see the likely answer before you are committed to it.

Then please tell whoever is handling your financing that this is a short-term rental purchase, before the appraisal is ordered rather than after. Form 1007 has to be requested, and the choice between the two documentation paths is worth making deliberately rather than by default.

From there, you can get pre-approved with your income, debts and credit actually reviewed rather than estimated, and choose the option that works best for you. That selection can change as the file comes together.

Common questions

Can I use short-term rental income on a home I am going to live in?

No. Fannie Mae's short-term rental section applies to one-unit investment properties only, and rental income from a principal residence generally cannot be used to qualify at all. There are two narrow exceptions on a primary residence, and neither is about nightly rentals: boarder income from someone renting a room inside your living space, and rent from an accessory dwelling unit on a one-unit property. That second path runs on a twelve-month lease basis with a different discount and a cap on how much of your income it can be. A second home you keep available to yourself is also outside this section.

Does the seller's booking platform history count as proof of income?

Not as the documentation on a purchase. The guide names two acceptable sources for establishing monthly gross rental income. The first is a Single-Family Comparable Rent Schedule, Form 1007, completed on a standard long-term basis. The second is validated rental data for other short-term rentals, from a multiple listing service or from property management companies. That validated data has to cover three comparable properties with their rates and the number of days each was rented in the last calendar year. The seller's own earnings are useful for your own decision about whether to buy, and they are not one of the two named sources.

How much of the gross rent actually reaches my file?

Half of it becomes net rental income, and then the property's full monthly payment comes out of that half. The guide multiplies the monthly gross rental amount by 50 percent, and says the other 50 percent accounts for vacancy losses and maintenance expenses. Subtracting principal, interest, taxes, insurance and any association dues from that figure gives adjusted net rental income. A positive result may be used to offset the payment on the property, but a negative result is added to your monthly obligations in the debt-to-income ratio.

What happens if the property has never been rented before?

The purchase path does not require the property itself to have an operating history, because neither of the two documentation sources looks at what this property has done. Form 1007 is the appraiser's opinion of long-term market rent, and validated rental data comes from three comparable short-term rentals elsewhere in the market area. What the guide does require is that the property be legally permitted to operate as a short-term rental, including local registration and licensing. A refinance is handled differently, because there the file starts with your most recent individual federal income tax return including Schedules 1 and E.

When does this rule actually apply to my loan?

Fannie Mae published the restructured rental income requirements in Announcement SEL-2026-08 on September 2, 2026. Lenders are encouraged to implement the changes immediately and must do so for all loans with application dates on and after November 1, 2026. If you are shopping now, please ask whoever is handling your financing which version they are currently applying, because a file started before that date could be underwritten either way depending on the lender.

Do these rules apply to FHA or VA financing too?

No. Everything above comes from Fannie Mae's Selling Guide and governs conventional financing. FHA and VA are separate rulebooks with their own treatment of rental income, and both programs also carry occupancy requirements that make a pure investment purchase a different conversation. If you are comparing programs on a rental purchase, the products overview lays out what each one is built for.
