I’ve had good results with Transunion’s Smartmove service. It’s really simple for the landlord side, the applicant is billed for the service. The only thing you get are the reports you specify.
So my experience comes from GA and FL and a property manager is going to charge you between 10-15% to manage your long-term rental. You would still want to vet them for managing properties in the same area as yours so that they understand the rental market.
