I generally sell property in the city but there are some freaking crazy good deals in Temecula right now.
You can buy for less than $100 ppsf without HOAs or mello-roos.
Considerations:
At commute time, the drive to/from San Diego can be upwards of 2 hours.
The politics favor a rather contemporary version of reactionary conservatism (think Glenn Beck).
Anecdotally speaking, I have had a lot of conversations when showing property in Temecula that start with “Well I’m not a racist but…”.
Significantly hotter during sunny days.
Significantly larger average house size than San Diego (good for RV’s and toys).
Very high levels of development bonds and municipal taxes (that means total property taxes often more than double other parts of the state).
Close to lots of adult recreational activities (wineries, off-roading, lakes, shooting ranges).
Generally good schools.
I don’t say this to promote or denigrate the area.
It is not a place that I would want to live but a lot of people really love it there.
Others, like me, are content to visit it occasionally and then go home.
