This site has no listings. It's the financing side of buying one: your county's 2026 loan limit, what FHA, VA and conventional loans ask for, and whether the rents carry the payment.
Enter price, units, rents, taxes and loan type. Get the down payment, FHA mortgage insurance (MIP), the monthly payment, FHA's self-sufficiency test and how much rent a lender will count.

Home loans stop at four units. What changes at five, and how to send a 5-20 unit purchase to a commercial desk.
A two-to-four unit building you live in still gets a home loan, the same FHA, VA or conventional mortgage a single-family buyer uses. Three things are different. The loan limit is higher, and it scales with the number of units. Lenders can count part of the rent from the other units as your income. And the rules get stricter at three and four units: FHA adds a test that the rents must cover the payment, and FHA wants three months of payments in the bank after closing on three or four units, while VA (when rent is counted) and Fannie Mae’s automated approvals want six.
Start with your county’s 2026 loan limit for the unit count you’re looking at. FHA’s floor for a fourplex is $1,041,125, and conventional loans have their own, higher limits. Then put the building into the calculator. On a triplex or fourplex with FHA, the self-sufficiency test can stop a deal that’s well under the loan limit; the guide to that test works an example.

How FHA, VA and conventional loans differ on a 2-4 unit home you live in: down payment, county limits, mortgage insurance, rent that counts and reserves.
No. Use a listing site or an agent to find the building. This site is for the step after: checking whether you can finance it and live in one unit.
It depends on the county. The floor, which 2,794 of 3,235 counties use, is $1,041,125. The ceiling in the lower 48 is $2,402,625. The county lookup on the loan limits page shows the exact figure.
No. FHA's single-family programs, VA and Fannie Mae's single-family loans all stop at four units. Five or more units is a commercial loan sized on the building's income.
Usually, yes. FHA, VA and Fannie Mae all count 75% of the rent from the units you don't live in, with conditions: FHA uses the lower of market rent and the lease, VA wants landlord experience and six months of reserves, and Fannie limits how rent is used if you have under a year of landlord experience.
