<prompt> Human: Long story short, somebody I know used to have a Secured home mortgage loan through Countrywide... but then shit hit the fan with Countrywide and they got bought out by BOA. In the process of the transfer of the loan BOA made a mistake, and forgot to include the collateral on the loan. They sent him letters asking him to sign and agree on a collateral but he refused, and for the past 4 years paid off his mortgage responsibly.However! Financial troubles caught up to him, and he can no longer afford to pay.He stopped paying, since the loan has no collateral, asides from destroying his credit score, what is the worst that could happen?This person is a senior citizen located in California.  <response>: BOA will take him to court, the judge will see what transpired, and he will lose his home. There is no scamming big money.
