The number one question here is what is your over-all goal with this property. Are you buying it for yourself to live in, are you buying to rent out, ect....i've lived in Philadephia center city area for many years and i work as a lending specialist for a local bank. I'd love to be able to go over a number of different options that you shoud definately take a look at. You can contact me at firstname.lastname@example.org or directly at 267-474-8050.
Fred is right, we would need and address or building. You would also need to consult your real estate professional regarding what the rents would be if you are buying it for investment. You can go to Philly.gov to check crime statistics.
Lastly, check out what else is in the area. Have you only seen this unit? Have you compared it to other units in the Fitler Square and surrounding areas. Before you purchase I would take some time to tour the area yourself. Walk around, stop at a coffee shop. Not just once, but a few times, morning, noon and night. This will give you a better bearing of what goes on at all hours. Whether you are going to occupy the unit or not you will want to be secure with your decision
I would ask you to present that very same important question to your Realtor, You really should be doing your home search with the assistance of a Realtor working for you as your Buyers Agent. There would be not cost to you for these services. The area you are speaking is a hight desireable area with easy assess to center city night life.
