Was that fast?

Last week we got an offer on our house...just 3 weeks after putting it on the market, and today we finalized all the paper work, etc. Now we are in a mad scramble to find a place to live as they want us out by Sept. 15. We still have a 10 day option period where they can back out for any reason. I'm not saying I want them to back out but I wouldn't exactly be disappointed if I had a little more time to enjoy our home. As Annabelle (Jodie Foster) says in Maverick, "Was that fast, I thought that was fast!"
