Help us save our home

I'm asking for help in paying mounting legal fees in fighting a reverse mortgage foreclosure.This reverse mortgage was attained by actively soliciting my father ,he signed on to it at the age of 96 ,at the time my mother was terminally ill. I deeply believe he did not understand the legalities of this contract.There was no documentation of this mortgage in any of his papers , and try as I may ,I could not find who held the mortgage,apparently it had been bought & sold over and over .No one ever contacted me , until I found a notice on my door informing me a bank had taken over the property,and it would take $270.000 to settle . I find these practices to be unethical & amoral,this scenario is being played out all over the country, at a time when the most vulnerable in our society should be protected,they become targets for " legal" schemes. This is been the family home since 1973, and the only inheritance he left me,without it my wife & I are homeless so I'm desperately trying to fight .I've never done anything like this before, I have no choice but to ask for help. Thank You.
