My question involves a mortgage in the state of: Pa.
I just lost my childhhood home to a private sale that was actually caused by an illegal foreclosure. A sherrif's sale had been scheduled and my co-owner sister was approached by a buyer who basically low balled her due to the sherrif's sale and she advocated signing a purchase agreement which we both did. After signing the original agreement I continued to conduct research and found several questionable meaning criminal-fraud issues with the original mortage that was defaulted on by us. These issues range from the obvious, over-stated income by loan originator, to the subtle, MERS issues, securitization issues etc. My financial situation prohibited me from seeking a HALAR or forensic audit of the loan docs and therein lies an area of review/concern. Once these issues came to light I attempted to back out of the sales agreement but had not included a escape clause(I did not produce the sales agreement-buyer's attorney did) but I was sued by them and eventually lost as I had really had no legal representation nor much of a leg to stand on. Having said all that there a plethera of issues here but they all boil down to a simple question. Is it worth pursueing this from a legal standpoint? Meaning what could I accomplish if I were successful in getting this investigated for fraud and such proven, investigated for note ownership, securitization, etc. , and if these results proved the foreclosure was not legally carried out, could that result in me re-aquiring the property which yes I could afford to pay for now given the chance.
I recognize anyone interested needs additional information which I will gladly supply, but I a) want that property to leave to my kids someday unencumbered and b) don't like getting taken advantage of by a system that is wrong!
Any information is appreciated.
