We are selling our house and had a new house we were trying to buy. I had an offer on my house but it was well below what we wanted to get. I accepted this offer to hurry up and get the house we wanted. The house we were trying to buy had an offer 1 day before us and it looks like we lost it. I have since had a backup contract for the full price on my home. Since I agreed to the lower price for obvious reasons and now I see that it was in vain, can I cancel the first offer and go with the backup for full price. There has been no inspection yet and it is on the 3rd day of the agreement. What are my options?
