Answer
What is the difference between GRM and cap rate?
Gross Rent Multiplier (GRM) is sale price ÷ annual gross rent — a quick top-line ratio. Cap rate is Net Operating Income ÷ sale price — a yield-based measure that accounts for operating expenses. GRM drives pricing on smaller (2–4 unit) deals where expenses are similar; cap rate drives pricing on larger (5+ unit) deals where expense structures vary materially.
When GRM wins
On 2–4 unit residential income deals, owner-user buyers use GRM because they care about debt service against gross rents, not stabilized NOI. That's why GRM comps move 4-unit pricing in LA more than cap rate.
When cap rate wins
On 5+ unit commercial multifamily, lenders and institutional buyers underwrite NOI, so cap rate is the operative metric. Two buildings with identical GRMs but different expense ratios will trade at very different prices.
Local context
This answer reflects how deals actually trade in Cameron Samimi's core coverage area: the South Bay (Torrance, Redondo Beach, Hawthorne, Lawndale, Gardena, El Segundo), Long Beach (Alamitos Beach, Belmont Heights, Wrigley, Bixby Knolls, Downtown), and Westside LA. Pricing, rent regulation, and buyer depth differ materially between these submarkets — verify the specifics for your property before acting.
