Mr. Solomon is right. Just stop to think who has to pass judgment on the property you are looking at? Letâ€™s take a quick count you, the Lender, The City of Philadelphia, the home inspector, The Pest Control Company and above all Appraiser. Since being in the Real Estate business for longer then I want to admit to I have found that buying a property on a block with an abandon property is taking a large risk. Now with the property next door is abandon the risks is much higher and then add trash in, you now have insects to deal with. The best and safe thing to do is run to another property unless you feel lucky and plan to invest in the other house next door when it becomes available.
