Unless the house is made out of concrete it will have termites in Socal at some point. In general, termites are very slow acting and not half the problem of water damage/dry rot. The only reason that they are such a big deal in the RE sales process is because someone decided to amke it an important part of the contract. A 50 year old termite infested beach bungalow is a problem. A 10 year old tract home with with evidence of termites found, no big deal. Treat the problem and move on.
