J.,
I believe you would have heard right away if it was an offer on your house. And I don't think it's rude or unprofessional if they were signing papers for anthother house in your driveway. If you had been in the house at the time, that would have been rude. Also, I agree that you should call their realtor and ask for feedback. If they did choose the other house they should be able to tell you what they liked better about it. Sometimes it is just a personal choice but maybe it is something simple that you can correct for the next prospecitve buyer. Good luck! We sold our house by owner about 3 years ago and it was the most horrible experience. Just a few words of advice. The seller's market is horrible right now. When we were selling our home it was just beginning to dive. We priced our house close to what some comparables were priced at. We received some offers that were about 20,000 under our asking price but would have given us a profit. We did not accept the offers and 9 months later (1/2 month before out son was born and six months into making two mortage payments) we ended up dumping it for 20,000 under those first offers.
