Perhaps you no longer have enough income to pay your loans. Or you can afford the payments but don't qualify for refinancing under the new plan because the value of your home is too far below the balance of the loan. If you're far enough underwater, you're probably questioning the wisdom of writing a monthly check on a place that may take 10 or 15 years to get back to the value it had two or three years ago. It isn't easy to come up with the answer, and if you have moral misgivings about not making good on your mortgage, a religious officiant may offer as much useful guidance as a financial planner.
In an economic environment like this one, however, the consequences of giving up on your mortgage may not be as painful as they were a few years ago. Yes, it's almost always preferable to negotiate a better deal on your existing mortgage than to walk away. But if you can't work things out with your lender, you probably won't be sued. You shouldn't receive a major tax bill, either. And the damage to your credit will not be permanent or insurmountable.
Let's look at these last three in order.
Your lender: First off, let's define what we mean by "giving up" on your current mortgage. It may mean trying for a short sale, where the lender allows you to sell your home for less than the mortgage amount. You may also hand over the deed to the home in exchange for the lender agreeing not to start foreclosure proceedings (a "deed in lieu" in industry terms). Then, there's foreclosure itself, and the possibility that bankruptcy judges may soon have the power to adjust the terms of primary mortgages.
That said, just because you're ineligible under the Obama plan doesn't mean that your lender or servicer won't ultimately adjust your mortgage anyhow. Collectively, there are enough people in trouble or underwater on their loans that they have plenty of leverage if they're willing to play chicken with their lender and threaten to stop paying.
The problem is, the lender can play chicken, too, by threatening to come after you for the balance of any money you owe -- whether it's the difference between what you sell the property for yourself and the remaining mortgage, or the loan amount leftover after the lender sells your property in foreclosure.
The lender may not follow through, though. "What our membership is telling us is that it can be cost-prohibitive to chase down a borrower who is already in financial distress," said John Mechem, a spokesman for the Mortgage Bankers Association. "You can't squeeze blood from a stone." They may, however, still come after people with high incomes who walk away from jumbo loans that are way underwater or loans on investment properties.
Some states have laws that may specifically prohibit lenders from pursuing borrowers for the balance of many mortgage loans after foreclosure, though the particulars vary. Arizona and California are among these states, according to Steven Bender, a professor at the University of Oregon School of Law. It's best to talk to a lawyer to determine your state's rules.
