You can rent out your existing Temecula home while renting a place in North County.
I was debating between Temecula and North County as well back in 2009, but ended up getting a townhome in Carlsbad. Loving the fact that work is only a little bit away, but wondering how big of a house I could have had. I have a couple friends in Temecula that are trying to get back to a place nearby in North County as well.
