I would like to know that as well, as the few property management companies that I have used have not been at all satisfactory. The have tended to over-represent the tenant's problems over me the property owner who pays the bills. Communication has always been the sticking point for me as I am not quick to trust my investment to someone with no skin in the game and who hasnt' gotten my ok on spending my money.
In my mind it might be better to find a realtor or other money partner in long distance properties and pay them a management fee for that service. Find someone who is also an investor. Most property management issues, once the tenant is in place, other than collections, are problems or repairs in the property. If you have a few good subcontractors - electrician, plumber, appliance guy you can handle most of it. Also have a lease agreement that makes the tenant responsible for any repairs up to say $150 - $300 per item. This will keep them from driving you crazy with nonsense items that so often come up or things that they have created anyway.
I have this relationship in a CA commercial property, and it seems to work pretty well. I sleep much better when I know what is going on with my real estate investments.
If you need to hire a property manager, my suggestion is gets lots of references and talk to those references prior to signing. I hope this helps you.
