Single-Family vs. Multifamily Rentals: Which Is the Best First Rental?

What It Covers

Dave Meyer and Henry Washington answer four forum questions from new investors, covering the single-family versus small multifamily debate, how to handle inherited tenants paying well below market rent, whether to BRRRR or flip with $100k, and why house hacking fails mathematically in high-cost markets like Seattle.

Key Questions Answered

• •Single-family vs. multifamily at low price points: Small multifamily outperforms single-family for cash flow and wealth building, but finding a quality duplex under $125,000 in a job-growth market is unrealistic. At that price point, prioritize asset quality over property type — a solid single-family beats a distressed multifamily every time for a first out-of-state investment.
• •Vacancy risk math favors multifamily: A two-month vacancy on a single-family rental eliminates 16% of annual revenue. The same vacancy in one unit of a four-unit property costs roughly 1.5% of annual revenue. This risk-mitigation math makes small multifamily (four units or fewer, which qualifies for residential financing with 5–10% down) structurally superior for portfolio stability.
• •Inherited tenant rent increases — the stair-step method: When a tenant pays significantly below market ($635 vs. $1,200 market rate), pull comparable rental listings, show them the data, and ask what they can reasonably afford. Then negotiate a monthly stair-step increase toward a mutually agreed target. Retaining a reliable, long-term tenant at $1,000 versus $1,200 is often a financial wash after factoring in vacancy costs.
• •BRRRR vs. flip decision framework: BRRRR suits investors comfortable with long-term landlord responsibilities and lower risk — renovation timing pressure is reduced because a poor sales market means you simply hold and rent. Flipping suits investors wanting faster capital returns within six to eight months but carries higher risk. Clarifying whether you need short-term or long-term returns resolves the choice immediately.
• •Underwrite conservatively using 10% below agent rent estimates: Set rental income projections 10% below what property managers or agents quote. This buffer absorbs rent softness, concessions, and vacancy without pushing a deal into negative cash flow. Markets like Denver currently show flat or declining rents, and investors who underwrote at peak figures are now absorbing losses that conservative underwriting would have prevented.
