Los Alamitos in short: The typical home is worth about $1,572,000 as of August 2026, up 5.0% in a year, against about $1,179,000 across Orange County. About 36 homes are for sale. Typical rent is about $2,980 a month. First-time buyers can combine county and state down payment programs.
Los Alamitos is a small West County city on the Los Angeles County line, next to Seal Beach, Cypress and the unincorporated community of Rossmoor. It is home to the Joint Forces Training Base Los Alamitos and a compact business district along Katella Avenue.
The housing is mostly single-family homes from the 1950s and 1960s, plus some townhomes and condos. Few homes list in a typical month, and demand is driven heavily by the schools. Los Alamitos Unified School District serves the city and nearby Rossmoor and is one of the main reasons buyers search here.
Because inventory is so thin, I help buyers get ready early: pre-approval, a clear read on recent sales and a plan for what to do when a home comes up.
