FHA Loans for Multi-Unit Properties — Duplex, Triplex & Fourplex

One of the smartest uses of FHA financing available to California buyers today is purchasing a 2, 3, or 4-unit property. You become a homeowner and a landlord at the same time — with as little as 3.5% down.

How It Works

FHA loans allow the purchase of 2–4 unit residential properties as long as the borrower occupies one of the units as their primary residence. You live in one unit and rent out the others — often called “house hacking” — using the rental income from the other units to offset your mortgage payment.

2026 FHA Loan Limits for Multi-Unit Properties

Units High-Balance Limit (High-Cost CA Counties)
2 Units $1,599,375
3 Units $1,933,200
4 Units $2,402,625

Using Rental Income to Qualify

Rental income from the non-owner units can be used to help you qualify:

  • No rental history: 75% of the lower of appraised market rent or the actual lease amount is used as income
  • With a rental history (2-year tax return): Average net rental income from Schedule E — depreciation, mortgage interest, taxes, and insurance can be added back

3–4 Unit Self-Sufficiency Test

For 3 and 4 unit properties, FHA applies a self-sufficiency rule: the net rental income from all units must equal or exceed the total monthly mortgage payment. The property must essentially pay for itself based on market rents.

Reserve Requirements

  • 3–4 unit properties: 3 months of PITI reserves required at closing (beyond down payment and closing costs)
  • 1–2 unit properties: Per AUS findings (typically 1 month for manually underwritten loans)

A step-by-step path to buying a small multi-unit home

  1. Confirm the county limit for 2 to 4 units and your target price (see FHA limits).
  2. Collect rent information for each unit: current leases, rent rolls and operating costs.
  3. Have the appraiser prepare the rent schedule used for qualifying income.
  4. Check reserves: the 3 to 4 unit rule requires three months of PITI after closing.
  5. Plan your move-in as your primary residence, since occupancy is a core FHA requirement.

A worked example of the self-sufficiency test (illustrative example, not a quote)

Assume a triplex where each unit has an appraised market rent of $2,400. The three units total $7,200, and applying the 75% factor leaves $5,400 of net rental income. If the monthly mortgage payment, including taxes, insurance and MIP, is $5,000, the test passes with a $400 margin. If the payment is $5,800, it fails by $400, and you would need a lower price, a bigger down payment or a different structure.

Landlord realities to price in

  • Vacancy and repair costs rarely follow a spreadsheet, so keep a reserve beyond the lender minimum.
  • Insurance on a multi-unit building is typically higher than for a single-family home.
  • Existing tenants stay under their leases, so request lease copies and rent payment history during due diligence.
  • California tenant rules are detailed; consult an attorney about leases, notices and deposits.

Frequently asked questions

Can I use VA instead for a four-unit home?

Eligible veterans can buy a home with up to four units if they live in one, with up to 100% financing for eligible borrowers. See our VA multi-unit page for the details.

Does rental income count right away?

If there is no rental history, the lender uses 75% of the lower of market rent or lease amount. With a two-year history, income is based on net rental income from the tax returns.

What happens when I want to move out later?

The occupancy requirement applies when you buy. What you do afterward, including keeping the property as a rental, involves lender, insurance and legal questions, so talk with us and an attorney before planning it.
