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)
Practical Takeaways
- 2–4 unit purchases with owner-occupancy are eligible for 3.5% down
- Rental income from other units can be used to help you qualify
- 3–4 unit properties are subject to a self-sufficiency test
- 2026 FHA limits go up to $2.4 million on a 4-unit in high-cost California counties
