I just had a similar experience. I had offered Monday evening (the 4th), got an acceptance on one and a counter on two the 5th which I then accepted, and thought I'd sign a contract right away, but it took the broker 24 hours or so to get it to me and the sellerr, which I turned around right away that night (the 6th), but the seller didn't get it signed till the 11th when it was finally sent to ROFR. The thing that made me patient about it, is that the seller does have to get it notarized, and thats a PITA, plus its getting close to the holidays. I have to admit though I did wonder in the back of my mind if maybe they had a change of heart, since they were pretty fast at responding to the offer. Luckily that was not the case.
