Multi-Family Property Financing 2026: Guide to 2–4 Unit Mortgages
7 min read · 2025-09-08
House hacking with a 2–4 unit property can fund your mortgage with rental income. Here's how to finance one.
Owner-occupied multi-family properties (2–4 units) are one of the most powerful wealth-building strategies available to first-time buyers. You live in one unit, rent the others, and use that income to offset your mortgage. Best of all, these properties qualify for residential mortgage rates — not the higher commercial rates.
Loan Options for 2–4 Unit Properties
- FHA loans: 3.5% down, allows rental income from other units to help qualify, min 580 credit score
- Conventional loans: 5–25% down depending on number of units, better rates than FHA for strong credit
- VA loans: $0 down for eligible veterans, can buy up to 4 units with rental income
- USDA: Single-family only — does NOT cover multi-unit properties
Using Rental Income to Qualify
For owner-occupied 2–4 unit purchases, lenders allow you to count projected rental income from the non-owner-occupied units. For FHA, lenders typically count 75% of market rents. For conventional, documentation requirements vary by lender but 75% of lease agreements or appraiser-estimated rents is standard.
House hacking example: Buy a duplex for $400,000 with FHA (3.5% down = $14,000). Rent one unit for $1,800/month. Your mortgage is $2,600/month — you effectively pay $800/month to own a $400,000 property while building equity.
Down Payment Requirements by Units
- 2 units (duplex): FHA 3.5%, Conventional 15%, VA 0%
- 3 units: FHA 3.5%, Conventional 20%, VA 0%
- 4 units: FHA 3.5%, Conventional 25%, VA 0%
