The details are still negotiable, but it looks like after the dust settles first time home buyers will be eligible for a refundable tax credit equal to 10 percent of the purchase price of their home, up to $8,000. The home must be purchased between Jan. 1, 2009, and Dec. 1, 2009, and you must keep the home for 3 years or pay back the credit. While the previous $15,000 credit must be paid back over 15 years, the $8,000 credit does not have to be repaid unless you sell the home within 3 years.
