It appears that you have been through a lot and spent a lot to get where you are. Your best bet is to hire an attorney or at the very least consult with one to see what your chances of winning are before giving up.
You need to contact a lawyer who specializes in foreclosures ASAP. There are many remedies that can be brought before the foreclosure court, plus seeking a loan mod. Also I would be wary of any investors or attorneys that have too good to be true short sale options where you can still keep your home. A Chapter 13 case may be a final option to prevent a judicial sale and give you more time.
You really need to speak to a real estate attorney who specializes in litigation on mortgage loans, modifications, etc. I have one in our state I send all such cases too and the courts memorandum decisions are very long, very factual, very direct, and each includes different law provisions, damages, penalties and interest, etc attorney fees. So make sure you find one in your state who does litigate those. Check with your bankruptcy attorneys to see if one of them have carved out that unique area. I would never try one as it is a unique area of the law beyond bankruptcy and you want someone experience and learned in it..and not practicing on you! Good luck
Reading between the lines, I expect that you are not in a position to hire an attorney that will bill hourly to fight the foreclosure. I am not in a position to say where it would go, but I would usually refer a claim like this to a consumer firm that concentrates in violations of the various mortgage acts and regulations and consider other consumer protection provisions. There have been successful cases based on preliminary commitments to loan modifications. Usually, a firm working those cases will do so with a contingent fee agreement.
The scope of this space does not afford an opportunity to adequately advise you. The response provided is intended to be informative, but not final. You are advised to arrange a consultation at which all facts and documents can be explored and terms for representation agreed. An attorney-client relationship must be formally established.
Your case is not unusual. We see botched loan modifications regularly. You need to find a law firm with good comprehension and experience in the loan modification arena as well as solid abilities in foreclosure defense. The firm should also have strong capabilities in bankruptcy and mediation to determine all your options. Don't assume you don't qualify or can't get an affordable loan modification, and don't give up. There are so many good modification options out there. However, you do need a good law firm to make sure you get what you deserve. Whatever you do, DON'T GIVE UP! Good Luck, Rick Rogers
