If the purchase agreement says you need a termite clearance then closing the loan without a clearance could be problematic. You may want to talk to escrow and your lender about that with regards to obtaining the clearance after the loan has funded. As long as the wood repair is done, the clearance can be issued the day the put the tent up as opposed to when they take it down 3 days later. Otherwise just get the work done the day of closing. There are alternate treatments besides tenting as well. You can call Truly Nolen and ask about the liquid treatment they have. There are some possible alternatives.
