Lawmakers are trying to extend and expand an $8,000 federal tax credit for first-time homebuyers

The latest Senate proposal would drop the requirement that the credit be available only to first-time buyers, broadening the reach of the program but also adding to its cost, estimated by congressional analysts at $16.7 billion.

The backers of that idea, Sens. Johnny Isakson, R-Ga., and Christopher Dodd, D-Conn., chairman of the Senate's banking committee, have suggested that their measure be attached to another pending bill aimed at throwing a lifeline to people hit by the recession, an extension of federal assistance to the millions in danger of exhausting unemployment insurance benefits.

The stimulus-package credit allows first-time homebuyers to reduce their federal income taxes by 10 percent of the price of a home, up to a maximum of $8,000 is set to expire Dec. 1.

The Isakson-Dodd proposal would extend the credit to June 30, 2010. It would also remove the first-time homebuyer requirement and raise the eligibility income limit to $150,000, or $300,000 for a couple. That's double the current phase-out limits.

Brookings Institution economist Ted Gayer wrote in a recent report that the tax credit is "very poorly targeted." He calculated that of the 2 million or more people who would make use of the credit if it were extended for a year and expanded to cover all buyers, only about 383,000 would be additional sales motivated by the credit. He estimated that the real cost of the credit would thus be more than $40,000, rather than $8,000, per buyer.

"Homebuyers for the past two years have been sitting on the fence and we needed something to move them into the market," said Lucien Salvant, managing director for public affairs at the National Association of Realtors. With more foreclosures coming next year, "to knock the props out of the housing market at this point would not be a wise move."

The NAR, together with the NAHB and the Mortgage Bankers Association, have been running ads in the Washington area urging Congress to extend the homebuyer tax credit.
