Qualified people who hope to receive a tax credit must have an accepted contract by April 30, 2010 and the purchase has to be closed by June 30, 2010. 

Qualified first time home buyers can receive up to an $8,000 tax credit and others can receive up to $6,500 if they have lived in their homes 5 of the last 8 years.

Thanks,
