The mechanics of the deal are usually the hard part. I recently spent almost 100 days pursuing a small table. Lots of long gaps in communication and being "out of town" by the seller.
I had given up, but then got a text with a real phone number. Once we talked on the phone the deal was done in a week. She turned out to be really nice and even met me half a mile a way from my work, which was where her mother lived.
