What it means for buyers and sellers
What the numbers say about the market: a stable, owner-occupied neighborhood with a high share of families and a growing share of residents over 65 (20.4% in 2020, up from 17.3% in 2010). That second number is the one to watch. As long-time owners downsize, more of the original single-story homes come to market, and they are the homes younger families and rebuilders compete for.
Household income here ($200,833 median) sits far above the county, which is consistent with the price of entry: at today's median, a 20% down payment is a six-figure sum and the mortgage payment alone runs well into five figures a month.
The housing stock
Rossmoor's housing stock is the simplest in the county: 3,430 single-family homes built between 1957 and 1961, one apartment complex and one townhouse complex, 3,765 units in all (2020). The homeowner vacancy rate was 0.6%, which is to say almost nothing sits empty. Average household size is 2.92, high for Orange County, because so many of these homes hold families with school-age children.
Schools, parks and services
Rossmoor is served by the Los Alamitos Unified School District; four of its six elementary schools (Rossmoor, Weaver, Lee and Hopkinson) are inside Rossmoor. The Rossmoor Community Services District, run by an elected board of residents, looks after Rush Park, Rossmoor Park, two mini parks, the Montecito Center, street lighting, street sweeping and the parkway trees; the County of Orange provides everything else. Residents voted against becoming a city in 2008, about 72% to 28%.
