Depends on your personality and skill set. When I rented I watched the property management company do a shitty job on all of the work they did. They would treat the renters (not their customer but their customer's customer) with pure contempt. One place would not let me see the lease terms until I paid a non refundable deposit up front (I walked). Another presented a lease renewal with open ended charge backs and used pretty words to tell me how fair they were but refused to modify the lease (I moved).

On the other hand I watched my wife tell a male owner that she would not accept a rent increase and he backed down.

Overall if you only have one property, have the right skill set and personality I would say you are better off doing it yourself. If you cannot say no to a young woman then you had better let someone else take care of it for you.
