What Is Multifamily Financing?
Multifamily financing spans two worlds: residential loans for two-to-four-units (FHA, conventional, VA) and commercial loans for five-plus-units. The 5-unit threshold is the break: 2–4 units get mortgage rates, 30-year terms, and personal-income underwriting; 5+ units get DSCR-based underwriting, shorter terms, and often balloon payments. FHA loans allow 3.5% down on 2–4 units with owner occupancy. Investors use multifamily financing to leverage NOI and scale portfolios.
Multifamily financing is the range of loan products used to purchase or refinance properties with 2+ units—including residential loans for 2–4 units and commercial loans for 5+ units.
At a Glance
- What it is: Loan products for 2+ unit properties—residential (2–4) and commercial (5+)
- Why it matters: Financing terms drive returns; 2–4 vs 5+ is a major split
- Key detail: 5-unit threshold: residential → commercial; FHA/conventional → DSCR
- Related: Residential loan, commercial loan, FHA loan, mortgage, DSCR
- Watch for: Commercial loans have shorter terms and balloon risk; plan refi or sale
How It Works
Residential tier (2–4 units). Residential loans apply. FHA loans allow 3.5% down with owner occupancy. Conventional mortgage programs support 15–30 year fixed terms. Underwriting uses personal income, credit, and DTI. Ideal for house hacking and small two-to-four-units investors.
Commercial tier (5+ units). Commercial loans apply. Underwriting focuses on NOI and DSCR—can the property’s income support the debt? Terms are often 5–25 years with balloon payments. Rates are higher than residential. Agencies (Fannie, Freddie), banks, and CMBS lenders offer multifamily financing for apartment buildings.
Agency and portfolio options. Fannie Mae and Freddie Mac have dedicated multifamily programs—competitive rates, longer terms, and DSCR underwriting. Portfolio lenders (local banks) may offer more flexibility for value-add or smaller deals.
Real-World Example
Jennifer’s scaling path. She bought a 4-unit with an FHA loan (3.5% down, owner-occupied). After 14 months, she moved out and refinanced to a conventional mortgage—no longer owner-occupied, but the property qualified as residential. Two years later, she bought a 12-unit with a commercial loan—DSCR of 1.25, 20-year amortization, 5-year balloon. Her multifamily financing strategy matched each property’s size: residential for 2–4 units, commercial for 5+.
Pros & Cons
- Residential loans for 2–4 units: low down payment, long terms, favorable rates
- Commercial loans for 5+: NOI-based underwriting; no personal income cap
- Agency programs offer competitive multifamily financing for larger buildings
- Commercial: shorter terms, balloon risk, higher rates
- FHA requires owner occupancy; limits non-owner-occupied 2–4 unit options
- DSCR requirements can limit leverage on commercial deals
Watch Out
- Balloon risk: Commercial loans often have 5–10 year balloons; plan refi or sale before maturity.
- DSCR floor: Lenders typically require DSCR of 1.20–1.35; low NOI limits loan size.
- Rate environment: Multifamily financing rates move with Treasuries and spreads; lock when terms work.

The Takeaway
Multifamily financing splits at 5 units: residential loans for 2–4 units, commercial loans for 5+. Match your multifamily financing to property size, strategy, and hold period—and plan for balloon risk on commercial deals.
