Five Reasons the U.S. Doesn't Need More Home-Buyer Perks

Congress is working on a new and even more generous set of perks for house buyers. A tentative deal in the U.S. Senate would extend the closing deadline for an $8,000 subsidy for first-time buyers to July 1 from Nov. 30. It would also boost the program's income limits for singles to $125,000 from $75,000 and for couples to $250,000 from $150,000, and would offer a new $6,500 reward for existing homeowners who buy again. (More on the home buyer tax credit.)

The National Association of Realtors has called such an extension "essential." The Mortgage Bankers Association agrees. The National Association of Home Builders says, "Failure to act now could derail the fragile housing recovery even before it has time to take root."
