Small Multifamily Real Estate Investing Guide

Market Context

Advantages of Small Multifamily

• Residential financing: 1–4 unit properties qualify for conventional and FHA loans — the best rates available
• Reduced vacancy risk: A vacant unit on a duplex means 50% vacancy — a vacant SFR means 100% vacancy
• Higher gross income per dollar invested: Multiple units typically produce stronger cash-on-cash returns than equivalent SFR investments
• House hacking potential: Live in one unit, rent the others with owner-occupant financing and 3.5% down

How to Analyze a Small Multifamily

Calculate gross scheduled income (all units at full market rent). Subtract vacancy allowance (5–8% in tight markets, 8–12% in softer markets). Subtract operating expenses (taxes, insurance, maintenance — target 35–45% of gross). Subtract debt service. The result is monthly cash flow. Divide annual cash flow by total cash invested for cash-on-cash return.

Finding Small Multifamily Deals

Small multifamily properties are listed on the MLS more frequently than larger apartment buildings. Filter for 2–4 units in your target market. Many owners of older duplexes and triplexes are small landlords who have owned for decades — motivated by age, maintenance fatigue, or tax planning. These sellers often prefer clean, fast offers to maximizing price through extended market exposure.

Management Considerations

Managing two to four units yourself is manageable if you live nearby. Key differences from SFR: more tenant interactions, shared utilities require careful lease drafting to allocate costs, and maintenance is proportionally more frequent. Budget $100–$200 per unit per month for maintenance and repairs as a reserve fund — actual expenses vary by property age and condition.
