According to the Clerk of Court records in Duval County the property was foreclosed upon in June of 2010. This explains why you received your binder deposit back. The attorney for Countrywide then, and now that BOA owns it was Marshall A Watson. They are in Fort Lauderday, FL. You can google them and write a letter to them to pass onto the lien holder, BOA. In your letter explain that you are interested in purchasing the property and were willing to do so prior and that you had a contract. I don't know how much this will help, but I have seen people do this and have it work. Additionally, you, yourself can search the clerk of the court records, it is a public site. You just need to know the first and last names of peoples records that you are searching. Good luck. You can always contact me at 382-6792 or my email, firstname.lastname@example.org
According to the tax records the property is still owned by your neighbors. Who had the deposit? BofA has this due to it being part of the Countrywide Bank debacle. Have your neighbors been making mortgage payments all this time? You should check with the county court to see if foreclosure proceedings have started. If they haven't then contact a real estate attorney to do a due diligence on the property. Be aware that the mortgage that they recieved when they bought it could have them owning more than what the property is worth. This would necessitate a short sale if foreclosure proceedings have not been initiated. Unfortunately you won't be able to negotiate with the bank who has the mortgage directly. Only the mortgage holder can.
All the best
