Cost of living in Temecula.
Temecula attracts households from both Los Angeles and San Diego who want newer housing and more space, and the cost equation here is unusually dependent on two things people underestimate: district assessments on much of the housing stock, and the distance to whichever job center you are commuting toward.
This page covers what drives housing cost in Temecula rather than publishing index figures. Cost-of-living averages blend very different households, and the numbers that decide your budget are specific to the property you buy. For anything beyond housing, consult current sources directly.
