Why should they?????? You bought a house, they loaned you the money to make payments, and now you have no equity because the home value has plummetted . Why is this the bank's fault?
What if the Bank decided that if you had lots of equity in the house because the home was now worth more than the loan value, and they went in and increased your loan value so that they could lay claim to some of your equity????? You would be angry and probably try to get a Class Action Suit against them too.
You need to continue making the payments, this is your obligation..
The lender is NOT BENEFITING from your being upside down. When they foreclose on the house, they will have to sell it for less than the loan value, and they will take a big, fat loss. If they decide to keep the house, and sell it when the property values go back up, they could be stuck with the house for 2 or 3 years before they recoup their losses.
Is the reason you want a loan mod is that you are ANGRY, because you are paying for something that is less than what you owe???? If that is the reason TOO BAD for you.
