Out-Of State Buyer in Philly

Hello, my name is Lukas Englert and I’m a New Yorker who is starting to look in Philly to purchase. I’m specifically targeting smaller rental buildings (2-4 units) in west Philadelphia area. My partner is based in Central Jersey and we are looking for a property manager to help manage day-to-day operations as we aren’t super close to the building. From those that I have found they are quite expensive and kill cash-flows. Does BP have any mangers they would recommend and do any out of state owners handle management themselves?

Thank you
