Who are "they"? The lenders? All lenders? I mean, generally speaking, in many cir stances it would make sense for a lender to rework a loan. A lender has no need for the collateral, they just want money. That's why they're in business. So a costly and burdensome pursuit of legal remedies is already something they don't want to do. But it's their choice, frankly. If they determine that they need to force foreclosure or pursue other state remedies, that's their choice. Just like it's their choice if they want to renegotiate with the borrower. That's how debt works.
The problem with sub-prime loans is that the borrowers, too often, cannot afford to make future payments, even on a modified loan. So why delay the inevitable? Lenders do not want to foreclose. They only pursue the annoying process of foreclosure because the alternative is bad.
Bankruptcy judges already have too much power in adjusting debt, in my opinion. Giving them even more power to adjust primary mortgages will only further freeze credit and make it more difficult for younger people like me to secure financing.
