Multi-Family Property Financing: The Investor's Guide to 2-4 Units
Financing a duplex, triplex, or fourplex opens powerful wealth-building opportunities. Here is how the math works and what loan programs are available.
Multi-family properties (2-4 units) are among the most powerful wealth-building investments available to individual buyers — and they are accessible through conventional, FHA, and VA financing.
Why 2-4 Units Are Different From Single-Family
For loan qualification purposes, 2-4 unit properties are still considered residential (not commercial). This means they can be financed with residential mortgage programs — conventional, FHA, VA — as long as the borrower occupies one unit.
For investment buyers (not occupying): conventional investment financing applies (25% down, higher rates).
Owner-Occupant Financing: The Big Advantage
If you occupy one unit (a "house hack"), you access owner-occupied financing: lower down payment, lower rates, and you can use rental income from the other units to help qualify.
FHA: 3.5% down on 2-4 units. 75% of market rent from non-owner units added to qualifying income with lease or appraisal support.
Conventional: 5% down on 2-unit, 15-25% on 3-4 unit. 75% of documented market rent added to income.
VA: $0 down on 2-4 units for veterans occupying one unit. One of the most powerful uses of the VA benefit.
The House Hack Math
Buy a duplex for $350,000 with 3.5% FHA down ($12,250). Rent one unit for $1,400/month. Your mortgage PITI might be $2,400/month. Your effective housing cost: $1,000/month. And you are building equity in both units.
Scaling Beyond 4 Units
Five or more units require commercial financing — different underwriting standards, larger down payments, and commercial appraisals. DSCR-style commercial lending applies.
