There are some great bargains in this area ( Temecula/Murrieta). We were over at a friends house in Redhawk , which is in Temecula, a few weeks ago and a house in that neighborhood that that sold for over $700.000 3 years ago just sold for $280,000 as a bank owned foreclosure.
As far as the commute-It is getting better as the work on the 15 is progressing. You can figure 1 hour to downtown SD on a good day. I have been doing it off and on for the last 8 years and all it takes is a comfortable ride and some good tunes

.
last thing- A good thing about living up here is that it puts you closer to the Desert, Big Bear and the Sierras. If you are into that kind of stuff

.
Good luck,
Tim
