Yes, rental income can help you qualify for a mortgage, but the lender rarely counts the full rent. For a rental you already own, the underwriter usually starts with your tax return (Schedule E) and adds back certain expenses. For a property you're buying, or a unit you haven't rented yet, most programs start with the appraiser's market rent or the lease, take a share of it to cover vacancy and upkeep, and subtract the property's own payment. Each loan program has its own method, and the house you're moving out of has its own rules.
Here's how FHA, conventional, VA, and USDA count rent, what changes for a duplex you'll live in or the house you're leaving, and what to have ready.
Gross rent vs. qualifying rental income
The number in your head is usually gross rent: what the tenant pays. Qualifying rental income is what's left after the program's method accounts for vacancy, maintenance, and the property's own payment (principal, interest, taxes, insurance, and any HOA dues). Then:
- If the result is positive, it may be added to your income, or only used to cover that property's payment, depending on the program and your landlord history.
- If the result is negative, the shortfall counts against you as a monthly debt in your debt-to-income ratio.
Rent on a property you already own
When a rental shows on your tax returns, the underwriter reads Schedule E. That schedule shows gross rent minus expenses, including depreciation. Underwriters typically add back non-cash and payment-related items, then average the result:
- FHA: averages the Schedule E figure and lets the lender add back depreciation, mortgage interest, taxes, insurance, and HOA dues. If you've owned the property less than two years, the income is annualized for the time you've owned it (HUD Handbook 4000.1, II.A.4.c.xii(I)(3)(c)).
- Fannie Mae: uses a similar cash flow analysis of Schedule E, with add-backs for depreciation, interest, HOA dues, taxes, insurance, and documented one-time expenses (Selling Guide B3-3.8-02, B3-3.8-04).
- VA: requires a two-year rental history on your tax returns for each rental, lets depreciation be added back, and requires documented cash reserves for each rental property before its income can be counted (VA Pamphlet 26-7, Chapter 4, Topic 2.n).
- USDA: counts positive net rental income only if it's been received for 24 months or more. Less than that, no rental income counts, though a loss still counts as a debt (HB-1-3555, Chapter 9, Attachment 9-A).
Rentals held in a partnership or S corporation show up on the business return (Form 8825) and your K-1 instead, and the underwriter reads them much like self-employed income.
Rent on a property you're buying
A property you're buying has no tax history with you, so the lender uses the appraiser's rent estimate and any lease. On a one-unit property, the appraiser completes a comparable rent schedule (Fannie Form 1007 / Freddie Form 1000). On a two- to four-unit property, the small residential income appraisal (Form 1025 / Form 72) includes the rent analysis.
- FHA: uses 75 percent of the lesser of the appraiser's fair market rent or the lease rent (4000.1, II.A.4.c.xii(I)(2)(c)).
- Fannie Mae: on a purchase, multiplies gross rent by 75 percent, then subtracts the property's payment (B3-3.8-02).
- USDA: its system applies a 25 percent vacancy factor to the rent you enter, but USDA loans are for a primary residence, and rent still needs the 24-month history to count toward repayment (HB-1-3555, Attachment 9-A).
The rent a seller or a listing advertises never goes straight into the ratio. The appraiser's figure, the lease, and the program's method decide it.
A duplex, triplex, or fourplex you'll live in
Buying a two- to four-unit home and living in one unit is allowed on FHA, VA, and conventional loans. Rent from the other units can help you qualify, with extra checks:
- FHA three- and four-unit self-sufficiency test. On FHA loans, the appraiser's fair market rent for all units, including yours, minus the greater of the appraiser's vacancy and maintenance estimate or 25 percent, has to cover the full payment (4000.1, II.A.1.b.iv(B)(3)(c)). Two-unit properties don't have this test.
- VA reserves and landlord experience. For a multi-unit home securing a VA loan, VA counts the prospective rent only if you have a reasonable likelihood of success as a landlord and verified cash reserves of at least six months of payments. The lender documents prior experience managing rentals or use of a property management company (VA Pamphlet 26-7, Chapter 4, Topic 2.n).
- Fannie Mae. Rent from a two- to four-unit principal residence can count under Fannie's subject property rules, which treat rent differently depending on your landlord history (B3-3.8-01, B3-3.8-02).
The house you're leaving
Keeping your current home as a rental when you buy the next one is common, and every program treats it cautiously:
- FHA: rent from a home you're vacating can count only if you're relocating more than 100 miles away. HUD wants a lease of at least one year after closing, proof of the security deposit or first month's rent, and an appraisal showing market rent and at least 25 percent equity (4000.1, II.A.4.c.xii(I)(3)(a)-(b)). Otherwise, the full payment on the old house generally counts as a debt.
- VA: prospective rent on the home you're leaving can only offset that home's payment, not add to your income. VA wants the rental agreement if there is one, and the lender has to judge the local rental market (VA Pamphlet 26-7, Chapter 4, Topic 2.n).
- Fannie Mae: Fannie issued new rental income rules on Sept 2, 2026. Lenders may use them now and must use them for applications dated on or after Dec 1, 2026, so until then some lenders still apply the prior version. Under the new version, a departing residence is qualified on market rent (not a lease), the rent can only offset that home's payment, and you need extra reserves if you have less than 12 months of landlord experience (B3-3.8-05). (Fannie Mae Announcement SEL-2026-08) Which version applies to you depends on your application date and your lender's implementation, so I'll confirm that on your file.
The move has to be real. Calling the old house a rental requires an actual move and, where the program asks, an actual tenant. My occupancy article covers why that matters.
Short-term rentals
Income from short-term rental platforms is seasonal and expense-heavy, so agency programs treat it carefully. Usually it needs to show on your tax returns before it counts. Fannie's new rules (optional now, required for applications on or after Dec 1, 2026) add a specific short-term rental method for one-unit investment properties with a more conservative factor, and the property has to be legally permitted to operate that way (B3-3.8-03). A projection from a website calculator isn't documented income. For investment properties, a DSCR loan qualifies on the property's cash flow instead, under the investor's method.
Roommates and boarders
Renting a room inside your home is boarder income, which is different from renting a separate unit:
- FHA can count boarder income with a 12-month history of receiving it, documented for at least nine of the last 12 months, a written boarding agreement, and proof the boarder shares your address. It can't exceed 30 percent of your qualifying income (4000.1, II.A.4.c.xii(I)(4)).
- VA can count temporary boarder income shown on two years of tax returns, if the local market supports it continuing (Chapter 4, Topic 2.o).
- USDA doesn't allow boarder income (Attachment 9-A).
- Fannie Mae generally doesn't count rent from your own principal residence, with limited exceptions for boarders and an accessory unit (B3-3.8-01).
Fictional example
This example is made up to show the method, not real numbers.
Chris is buying a duplex in Fort Worth's Near Southside and will live in one side. The listing says the other side rents for a certain amount, but the appraiser's market rent comes back lower. On an FHA loan, the underwriter uses 75 percent of the lesser of the appraiser's rent or the lease, adds that to Chris's income, and counts the full house payment as his housing expense. Because it's a two-unit, there's no self-sufficiency test. The listing's rent never enters the ratio, so we plan around the appraiser's figure from the start.
Common mistakes
- Counting the full rent. Programs apply a vacancy and maintenance factor or use your tax return, not the gross rent.
- Forgetting depreciation helps. Depreciation lowers your taxable rental income, but underwriters add it back.
- Assuming the old house's rent covers its payment. Many programs only let it offset, or don't count it at all, without history.
- Using a lease with a relative. Where a lender applies Fannie's new rules, its lease standards restrict family and interested-party leases on properties not yet on your tax returns.
- Waiting until underwriting to mention rentals. Rental properties change reserves, debts, and documents. Tell me up front.
What to have ready
- Two years of personal tax returns with Schedule E, and business returns with Form 8825 and K-1s if rentals are in an entity.
- Current leases for each rented property, and proof tenants are paying.
- Mortgage statements, tax bills, insurance declarations, and HOA statements for every property you own.
- For a departing residence: your plan for the house, and any signed lease and deposit proof.
- For a property you're buying: the listing, any existing leases, and the seller's rent roll.
- Statements for the accounts you'll use for reserves.
Next step
If you own rentals, want to buy a duplex and live in one side, or plan to keep your current house as a rental, let's run the numbers on paper first so you know what the underwriter will likely count. Book a call, or when you're ready, start an application.
