Paramount my response to the OP has nothing to do with Temecula. The OP could have said he lived in La Jolla and I would have posted the exact same thing.
Life has nothing to do with where you live and everything to do with how you live. If someone lives somewhere and for whatever reason they don’t like it why should they stay? It doesn’t work for him but it does work for you and a whole lot of others.
Nobody is wrong here, Temecula is a beautiful place. However for this particular poster it isn’t working out. He should sell asap and move to where he wants to live.
Seems like a no brainer to me. Any financial arguments to stay can be countered fairly easily.
