Quick Answer: FHA House Hacking in 2026
You can buy a 2-4 unit property with an FHA loan as long as you occupy one unit as your primary residence. The other units can be rented out — and 75% of the market rents can count toward your qualifying income. FHA has higher loan limits for multi-unit properties compared to single-family.
Example: $480K duplex, 3.5% down = $16,800. Monthly mortgage ~$3,000. You rent one unit for $2,200/mo. Net cost: $800/mo for a home you are building equity in. Check your FHA duplex eligibility →
2026 FHA Loan Limits for Multi-Unit Properties
| Property Type | Standard Areas | High-Cost Areas | AK/HI/USVI |
|---|---|---|---|
| Single Family (1-unit) | $524,225 | $1,209,750 | $1,814,625 |
| Duplex (2-unit) | $671,200 | $1,548,975 | $2,323,475 |
| Triplex (3-unit) | $811,275 | $1,872,225 | $2,808,350 |
| Fourplex (4-unit) | $1,008,300 | $2,326,875 | $3,490,300 |
Key point: In standard areas, FHA allows up to $1,008,300 for a fourplex — nearly twice the single-family limit. This gives house hackers access to much larger multi-family properties with just 3.5% down. Compare multi-family mortgage lenders →

FHA Multi-Unit Requirements (2026)
Owner-Occupancy Required
You must move into one of the units within 60 days of closing and live there for at least one year. You cannot buy a duplex and rent both units with an FHA loan.
Credit Score: 580+ for 3.5% Down
The same FHA credit requirements apply to multi-unit properties. 580+ credit qualifies for 3.5% down. 500-579 requires 10% down. Below 500 does not qualify for FHA.
Rental Income Counted at 75%
FHA allows 75% of subject property rental income to count toward qualifying income. Requires lease agreements or market rent appraisal. Some lenders require 2 years of landlord experience for the other 25%.
Self-Sufficiency Test (3-4 Units)
For 3 and 4-unit properties, FHA requires a self-sufficiency test: 75% of gross rents must equal or exceed the total mortgage payment (PITIA). This ensures the property can cover its own costs.
Reserves Required (3-4 Units)
For 3-4 unit purchases, FHA requires 3 months of PITI (principal, interest, taxes, insurance) in reserves after closing. This is above and beyond the down payment and closing costs.
FHA MIP Applies
FHA MIP (1.75% upfront + 0.55-0.70% annual for multi-unit) applies. MIP typically lasts the life of the loan unless you put 10%+ down. Factor MIP into your house hacking math.
FHA vs Conventional for House Hacking
