If you have friends/relatives who can do a little inspecting and maybe check to see that the tenants' repair demands are not unreasonable, I would go with a property manager who just leases the place for you.
We rented out our home while overseas for 3 years. We don't have the kinds of friends/relatives that can be imposed upon, so we hired one of the local real estate firms that has a property management service.
These firms make their $ off leasing fees; they take the first month's rent every time they lease your property. That is called "8% leasing fee." In addition, they charge a "management fee," typically 7 to 10 per cent of rent per month, to collect the rent, forward it to you, and direct tenants' complaints to tradespeople, who are then paid out of your rent before you get what is left.
Thus, they have an incentive to "get paying tenants in the place" ; and once the tenants are in there, to respond promptly to all complaints, and otherwise leave the tenants strictly alone.
For example: Our home's lease specified that the tenant was responsible for yard maintenance other than mowing (which we arranged for). The tenant, however, claimed he was told by the leasing agent that all yard maintenance was included in rent. Nobody from the property management outfit ever went out to inspect, until I came home on a business trip and went to inspect my home. What I found was my home in the midst of a wild jungle, shrubbery unclipped, weeds 4 feet high, a/c units choked by morning glory vines, etc. The grass was mowed, though!
Another potential problem is sneaky subletting by the tenants. Again, this goes on when property managers have no incentive (or time) to go out and inspect. One set of our tenants was two doctors, whose children were all grown. We found that their grown son had been installed in our finished basement the whole time they occupied our home, and five grandchildren had also lived there practically full time. Large holes had been made absolutely everywhere in the walls to hang heavy mirrors and pictures; the holes had been inexpertly patched by the tenants. My den had been fitted up as the doctors' office, and holes drilled in the hardwood floor to install a fiber optic home network. Our home was filthy. Fortunately, these were the "final" tenants so we were able to insist that their security deposit be used to clean our home thoroughly. (All other times, we, the owners, were dinged for cleaning between tenants, including almost $1,000 to clean the windows).
