Being in Ca you have big issues.
I have inspectors in Ca who talk about houses with serious damage after only a month.
Not trying to give you a scare, just the longer you wait ,the the more damage occurs.
Doing inspections I have learned one thing, do your homework. Talk to local realtors in the area or home inspectors, they will only use the best ones on thier own homes.
And they have plenty of experience with the way they work.
