Rental comps in San Diego, California

About the San Diego rental market

San Diego sits at the intersection of military presence, university enrollment, and year-round lifestyle demand, which creates one of the more durable rental bases on the West Coast. The tenant pool skews toward young professionals, active-duty and veteran households, and graduate students tied to UCSD, USD, and the broader biotech corridor that runs through Torrey Pines and Sorrento Valley. Single-family rentals perform well in submarkets like Chula Vista, El Cajon, and Santee, where price points are lower and families tend to stay longer. Closer to the coast — Pacific Beach, North Park, Mission Hills — you see stronger demand for smaller units and multifamily product, with renters willing to pay a premium for walkability and proximity to the beach.

From an underwriting standpoint, San Diego's biggest challenge is the relationship between purchase prices and rents. Cap rates in the core coastal submarkets have historically run compressed, often in the 3.5 to 4.5 percent range for stabilized assets, which means cash flow is thin unless an investor is buying with significant equity or betting on appreciation. Rent growth has generally supported that thesis over time, but investors need to stress-test their numbers carefully against vacancy and expense assumptions. California's tenant protection laws also matter here — the state's AB 1482 caps rent increases on covered units at roughly CPI plus five percent annually, and San Diego County has its own renter protections layered on top, so understanding which properties are exempt and which aren't is a real part of the analysis.

When running a rental analysis in San Diego, the practical move is to anchor your expectations by submarket rather than citywide averages, because the spread between a coastal zip and an inland zip can be dramatic in both rent per square foot and cap rate. Gross rent multipliers and price-to-rent ratios are useful gut checks here, and any deal that looks compelling on paper should be verified against actual lease comparables rather than listed asking rents, which tend to run optimistic in a market where landlords know demand is structurally strong.
