Congress also made it a bit interesting by allowing people who lived in their home for 5 years, sold it 2 years ago, and have been renting to also qualify. The whole purpose of expanding the tax credit to current home owners is to help stimulate activity in the 200k+ market. The first time home buyer credit helped clear out the 0-200k market but did little to help the higher price points. The main reason is that the lower end market for the most part are foreclosures and short sales, there's no seller "moving up". By expanding the credit the hope is that people who were hesitant about selling will now have some motivation to do so, they sell their 270k house and buy one for 350k. The 350k home owner sells theirs, and moves up/down/wherever, and so on. To be honest there has been fair activity in the 200-300k range, good not great and not good enough to really get the 300+ market really moving again. With the combination of current sellers, and those who may have sold a year or two ago and were waiting for the "right" time things should start moving in a positive direction and will lead us back to a more balanced market.
More to come as soon as I get a chance to read all the details of the new additions to the credit.
