You should contact in agent in the Drexel Hill area. They will be able to send you indepth details about properties in that area and in your price range. I work for Prudential Fox & Roach in NJ but we have agents all over PA that would be in the area you are looking.
Here is a link to search for an agent to contact. http://www.prufoxroach.com/Locator/AgentOffice.aspx
Either call or email an agent. If you know of someone who has purchased a home lately ask them for a reccomendation.
