Was the offer in writing? Did the seller sign it? What were the terms of the offer? Were all the terms met? Did you have an inspection contingency which allowed you or the seller to terminate the transaction if the inspection or repairs were too much?
Hard to know exactly what you are looking for. Real Estate is fairly complex once you get into the details. Hopefully you had a good agent represent you and they can answer many of my questions and advise you on how to proceed. Best of luck.
