Though the Home Buyer Tax Credit has been criticized in some quarters as bad policy, there was little political will in the house to oppose extending it through September 30, 2010. This will allow transactions already in progress to close. It only applies for buyer's who met the requirement of having a signed contract in place by April 30, 2010. The Senate is expected to approve this measure tomorrow.
