From a couple sources I've noted below, my read of the legislation is that the sale and purchase, generally completed at the time of closing on the purchase, must be after November 6, 2009 and on or before April 30, 2010 (or by June 30, 2010, provided a binding sales contract was in force by April 30, 2010).Also, make sure that you and your home meet the other qualifications for the tax credit. Full guidelines are also available in the IRS link below. Hope this helps. IRS info site NAHB info site
