Hiring someone to manage Rentals costs and expectations ?

[Mike S.]

What does one pay for and expect from a management company/person to take care of your rentals? 4 properties (2 condos, 2 small houses) generating roughly 15k p/month. The idea would be to not take the calls for the leakinf boiler or toilet but also to expect them to have a big list of vendors for the repairs that charge a fair price and not take advantage of these costs of repairs. Of coarse open to them taking control of the the leases too which think would help as Realtors get 1 months finders fee here. curious to here others costs and experiences cheers!
