As far as the comment below, real estate is a local market. If you do your research you will see that Philadelphia's market is one of the strongest and values for the most part have been very stable. There are even a few areas where values have gone up. Now is the time to take advantage of the market while there are still incentives to buy and please dont take advice from someone who has no idea about our local market.
