First off - I agree with Bill Gulley.
Paul B. The lender's primary underwriting criteria is called the "Three C's of Underwriting" and they are Credit Capacity and Collateral, not just capacity as you argued. Credit is the portion that is looked at as the borrowers "willingness" to pay.
Bryan Hancock I think you are too much "for the people" and not accepting the fact that many of these people lied on their applications. You also mentioned that with rent you can sue the owner, demand payment, follow them to collect. Yet with the mortgage the politicians have stepped in and made this type of recourse impossible. What if they did that to you with regard to rent? What if they stayed for an extra 13 months, rented out rooms, kept the rents collected, then left and you had no way to go back and collect - how would that feel?
Manyin this thread have argued about non Strategic Defaults - but what about those that have the ability to pay and simply choose to strategically default?
Clearly it is not ethical (once again this is for strategic defaults not defaults for cause or with job loss etc reasons). You entered into an agreement and you are leaving that agreement. The bank handed you $400K, you handed it to the home seller, and now you have decided you do not want to pay back what you were given.
You say it is just business? OK then, Mr. "Just Business" then feel the wrath of the bank, a lifetime judgement until you pay the residual, wage garnishments, etc. After all, you took the money. Oh, you say it is non-recourse? OK then, but why are you not paying taxes on that money YOU lost? Why must your neighbor pay taxes and you be let off the hook? That loss to the bank will be written off by the bank and therefore the bank will pay less in taxes - who is making up that loss? The rest of us.
I could go on and on.
In the end Strategic Defaults are a decision that a person makes, but there is no question as to the ethics of that decision.
And where is that recourse for all of those that "lied"? That was fraud that should end in jail time, fines, or both.
