You do not want to spend money on a house that YOU do not own!!!
If your Inspection revealed the termites;
The Seller is responsible for Section One repairs, which includes active termites, (even the Banks will do this on a Foreclosure), don't be afraid to ask,
I am hoping that you have an Inspection Contingency, but it doesn't matter in this case, ASK THEM,
But, if you're out in the cold, at least wait until it is your house; you could spend $1000 and then lose the deal, and NO ONE will pay you back that $1000!!!
