It sounds like you had a bad experience with a property manager. I am sorry to hear that. However, to ensure your asset is protected well - you will want to get a property manager. A good one that you vibe with and who gets the job done. It will cost you more in the long run if an emergency comes up and you have nothing in place.
A good property manager should be able to make your headaches go away. No late night calls. No soul sucking tenants. Someone keeping eyes on the building regularly. For example at our company we visit all our multi-fam buildings on a monthly basis to assess and make sure things are still good. That's on top of the regular day to day things.
If you really need another option, then a good realtor who will drive by the place routinely, place tenants for you, etc would be helpful... That said, that is a stones throw away from a good PM and it will probably be short lived, especially if the realtor gets busy.
