There is no reason to feel bad about living in Temecula, it sounds like you would be from your opening statements.
The Temecula bashing primarily comes from San Diego snobs who like to make themselves feel good by bashing people who live in Temecula/ and or Temecula itself.
I have been living in Temecula for 5 years, in Paloma Del Sol. I have been very happy living here – it is a properly designed community IMO: huge parks, nice size lots overall, wide streets, good distance between most houses, 5 pools. They just don’t “build em” like that anymore.
On South Temecula: In general IMO a less desirable area: lots of traffic (due to casino), close to the casino, a flat, featureless area. I’m talking about Wolf Creek, Temecula Lane.
Prime real estate in Temecula IMO: Area 211 which is basically bounded by Butterfield Stage, Margarita, Pauba and 79 South. 3 Prime communities: Paloma Del Sol (most parts), Paseo Del Sol and Vintage Hills. Crowne Hill is nice, but there are no pools and precious few amenities.
Redhawk: Some very nice areas including Morgan Hill and others as well. I would stay away from Vail Ranch in Redhawk.
On Temecula: Low crime, still fairly clean air, somewhat honest City Goverment but perfect? Ofcourse not, no place is…
BTW: Believe this or not, WHEN houses are priced CORRECTLY they seem to sell very fast in the 211 area.
