[quote=Fearful]The tax credit is for new houses, not resales.[/quote]
Are you sure? I know that was the case for the old credit, but I think the new credit extends that to first time home buyers buying existing homes as well.

The bill applies to buyers who haven’t owned a home in the last three years or who are buying a newly built home. The tax credit would take effect on May 1, immediately after the federal tax credit expires on April 30.
