This house was purchased in 2006 at a Sheriff sale for $32,100. The 2007 transaction referred to by others here is a corrective deed to get the owner's name right, as Sheriff deeds are often subject to errors. It appears to be owned by a non-owner-occupant (i.e., investor) and has a $50,000 mortgage on it, which originated in 2007.
What exactly is your interest, investor or homeowner? If you are looking for something on the market to buy and live in, get yourself a good agent. They will work hard to find you what you want and will help negotiate the buying process in all its complexity. I would suggest someone who is experienced in the area (even sub-area, because, for example, an area like Grays Ferry can be very different from Point Breeze, even block-by-block).
If you are an experienced investor looking specifically for off-market or even abandoned properties, I can probably assist in your search. I have been investing and helping experienced, funded investors obtain properties in Philadelphia. My services are fee-based, unlike the Realtors you may work with, and I provide specific solutions, such as acquisition and clearing title issues.
