Why 2-4 unit properties?
Small multifamily properties combine features of single-family homes and apartment buildings. Buyers can often use residential financing, live in one unit, and start receiving rent from the others immediately. Multiple rent streams also mean a single vacancy has less impact than it would on a single-family rental.
Because the buyer pool includes owner-occupants as well as investors, 2-4 unit properties are often easier to resell than larger apartment buildings in the same neighborhood.
Owner-occupied versus pure investment
Living in one of the units, sometimes called house hacking, can open loan programs that are not available to non-occupant investors and can lower your own housing cost. Buying purely as an investment usually means a larger down payment and underwriting focused more heavily on the property's income.
Neither approach is right for everyone. The best fit depends on your finances, how hands-on you want to be and your long-term plans for the property.
The metrics that matter
We encourage every buyer to understand these measures before making an offer:
- Net operating income (NOI): income after vacancy and operating expenses, before debt service.
- Capitalization (cap) rate: NOI divided by price, useful for comparing properties.
- Gross rent multiplier (GRM): price divided by annual gross rent, a quick screening ratio.
- Cash flow and cash-on-cash return: what is left after the mortgage, relative to cash invested.
- Debt service coverage ratio (DSCR): how comfortably NOI covers the loan payment.
- Price per unit and per square foot compared with similar recent sales.
Building a long-term plan
Many owners start with a duplex, then trade up to larger properties over time, sometimes using a 1031 exchange to defer taxes on the gain. Others hold one well-located property for decades. Before you buy, think about how this property fits your timeline, your financing capacity and the role you want to play in managing it.
