There are heaps of great opinions and advice in this post.  I think that a PM is easier IF they are professional and do what they are supposed to do.  I am very happy with my current PM but I have been on the receiving end of a poorly managed property.  It turned into a nightmare and eventually in court.  One good outcome was that we were very particular about the next one we chose.  We went to everyone available in the area and there was one that just stood out above the rest.  It pays to do you homework.
