The First Time Home Buyer Tax Credit extension is coming to an end next month for most people. The extension gives certain Federal employees and military personnel additional time to take advantage of it. For the rest of us, to qualify you must be in escrow on a property (and meet the other requirements of course) before May 1st.
There has been a lot of debate over whether the tax credit has helped sales. I think you'll find a lot of support among those buyers that have been able to take advantage of the credit and have actually received their refund. Feel free to leave your thoughts in a comment.
