First time buyers have to make a quick decision - do I purchase now and take advantage of the $8,000 tax credit that expires on November 30th or do I wait to see if Congress passes the $15,000 expansion that may be good until June, 1010? Well, there's a problem. The IRS is investigating 100,000 transactions for the tax credit for fraud. This may delay the extension and expansion - or possibly kill it altogether. If you plan to buy a home and are a first time buyer, this is the information you have to consider.
