The Tax credit was extended to home buyers who were already under contract prior to the end of April. Now the buyers who did not close on their home yet have until September 30th to close on the home. This is great news for buyers who had a delay in their closing date or who were under contract to purchase a short sale and did not get bank approval yet.
Here is the publication by the IRS confirming the news about the extension and also referencing what is required by the First Time buyers and Long Time Resident to claim their credits. http://www.irs.gov/newsroom/article/0,,id=225079,00.html
