A Conversation with Sen. Johnny Isakson (R-GA) About Slumping Home Sales and the Expired Home Buyers Tax Credit ATLANTA, GA (WABE) - This week brought some suprising, and very disappointing, numbers on home sales; both new and existing homes. One reason given for the slump: the expiration of the home buyers tax credit. Georgia Republican Senator Johnny Isakson was one of the authors of the tax credit. But he tells WABE's Denis O'Hayer he has no regrets about the decision not to extend it past the expiration date at the end of April. © Copyright 2012, WABE
