This may not help too much, but my dad rents only to military families (he owns two other properties and is essentially the landlord). He has very few problems (usually maintenance) with the tenants and they are typically down for 2 or 3 years of leasing due to the nature of TDY. As for someone to manage it, that's a tough one. Someone here with more experience might have a good solution.
