There are several variables such as did you have a buyer broker who submitted it for you or did you submit directly with the listing agent? Then did your offer have any contingincies? Was it contingent upon obtaing a mortage? If so what tyope of mortgage, a bank will not want to see teh buyer getting a fha mortgage as in nearly alls cases their guidelines are too strict to buy bank owne dhomes. Was it conditional upon a home inspection? if so did you make sure you put a date of 7 days or less? When was yoru closing dates, banks love 30 days or less but do not want to see more than 45 days.
You will be able to see when the house closes who the buyer was, it is public notice after all. You will not have an easy case as you have a lot to prove if it was a fix or if the other offer was better than yours, price is not always the leading factor, an offer with no contingoncies and a lower price is better than a higher offer loaded with contingincies. The bank wants to know the deal is firm. you ceratinly should meet with an attorney for teh 1st free meeting to get soen direction.
If you are going to make any other offers on bank owned homes, make sure you have an agent to represent you and guide you.
