These are the small multifamily questions I hear most, from new investors weighing a first duplex and from single family landlords thinking about stepping up to a fourplex.
Nothing here is legal, tax or lending advice. Talk to a lender, a real estate attorney and your CPA about your own situation.
For the full picture of why I target two-to-four unit buildings, read the small multifamily investing overview. For due diligence on occupied buildings, see how to buy a duplex. For the financing line between residential and commercial, read the fourplex investing page. Under contract, or close to it? Drop the building into REI Skool, the free group where I and other operators pressure-test multifamily numbers.
Straight answers
Duplex vs single family rental: which is better?
Neither wins everywhere. A duplex gives you two rent checks under one roof, so one vacancy hurts less and management is more efficient. A single family rental can be easier to resell and often attracts longer-staying tenants. I lean toward small multifamily for holds, but I underwrite each property on its own numbers.
What is considered small multifamily?
Generally two to four units: duplexes, triplexes and fourplexes. In US lending, one to four units is typically financed as residential property, while five or more usually moves into commercial lending.
How do you value a duplex or fourplex?
Small multifamily is often appraised with comparable sales of similar 2-4 unit properties, like a house, with income as a supporting check. Larger commercial buildings lean more heavily on income and cap rate. Pull real sold comps for the same unit count nearby.
Can I live in one unit and rent the others?
Yes, that’s house hacking. Many owner-occupant loan programs allow up to four units if you genuinely live in one, though rules on reserves and rent counting vary. Talk to a lender first. More at https://rental-property-investing.benlovro.com/house-hacking/.
What is a tenant estoppel and do I need one?
An estoppel is a signed statement from a tenant confirming their rent, deposit, lease term and any side agreements. If you’re buying an occupied building, it protects you from surprises after closing. Have your closing attorney prepare or review it.
What expenses are different on small multifamily?
Owners more often pay water, sewer, trash, common-area electric and shared landscaping. Shared systems like a single roof, sewer line or boiler also mean one repair affects several tenants at once. Build those into your operating budget.
How does Ben screen a multifamily property?
I buy at roughly the 70% rule and require the 1% rule as a screen: monthly rent across all units at least 1% of all-in cost, meaning purchase plus repairs plus closing. Properties that pass get a full line-by-line analysis. The screen is explained at https://rental-property-investing.benlovro.com/one-percent-rule/.
Should I self-manage a fourplex?
You can if you live close, have time and run a real system for maintenance, leasing and rent collection. As unit count grows, many owners hire a manager. Either way, include management in your numbers. See https://rental-property-investing.benlovro.com/property-management/.
Is small multifamily investing risky?
All real estate investing carries risk, including loss of capital. Multifamily spreads vacancy risk across units but concentrates repair risk in shared systems. Overpaying, thin reserves and unverified leases are the usual causes of trouble. Nothing here is a promise of results.
