He's really trying to avoid any kind of bankruptcy because he can afford the payments... he just didn't PAY them. He owns three businesses and it's something he thought was automatically being deducted, and his mortgage wasn't through PNC initially, but PNC bought the company it was through. He was ignoring the PNC mail as junkmail basically. Not a real good excuse or way to handle things but it's how it happened.
If they would do a modification which would allow him to pay MORE to get caught up on the back payments, he'd be fine. It's just paying it all as a lump sum that's basically impossible. And due to the income from the three businesses, I can't imagine any hardships are going to work in his favor.
He had a consultation with an attorney and the end result was essentially "yeah, you should probably pay that money", totally useless and waste of money.
