We'd need to know the exact address to pull up the comparable sales. If the property is in Central and West Kensington (19134 amd 19133), 3 bedrooms in ok condition can sell from $45,000 to $65,000 (maybe higher) depending on the block. The super tight streets where you can barely drive your car where there is no street parking will absolutely sell for the lower numbers. The condition of the other properties on the block will certainly have an effect on the sales price too. The 19122 zipcode, aka Old Kensington is bringing in the higher numbers. But again it depends on the block. I am unfamiliar with the name Greater Hgts. Can you tell me more about that?
