look at it this way, sign a 1-2 year lease, 2 years preferred. even if you and your wife do find that perfect home within that 2 year mark, plenty of builders will be willing to buy you out of the lease.

I would be extremely careful with who I rent from though. Temecula is very saturated with upside down flippers in danger of foreclosing. make sure you find out how much your future landlord owes on the rental.
