For some reason I cannot edit my comment so I'll reply again.
I've been researching property management companies in Cincinnati (where I live) and I've come to a few conclusions:
1. There are no good property management companies in Cincinnati. At least, there are no highly reviewed property management companies - only those with negative reviews or no reviews at all.
2. Owners looking to rent their homes might be a great demographic for this idea. While most of the property management companies state that they do regular maintenance checkups, they really aren't incentivized to do so and from the reviews I read they typically don't. They're really only incentivized to keep the renter renting so that they continue to get their cut. As it stands, owners and tenants are often at odds when it comes to "needed" repairs because the property management companies charge the owners $50/hour plus parts for any repairs beyond the most routine of maintenance. Basically the property management companies have stuck themselves between a rock and a hard place where it's almost impossible to make both the owner and tenant happy. If, however, the owners were paying a larger monthly fee that covered all repairs, they'd no longer be at odds with the tenant. Of course, the problem of "tenant abuse" would then fall on us. Hopefully by being proactive with regular maintenance the abuse could be mitigated somewhat.
I'm going to call a few property management companies tomorrow to get a better idea of what exactly is and isn't covered under their plans.
