Screen your tenants very well. If you are dilligent about selecting your tenants, it could be a profitable venture. If you don't, it will be a nightmare. I represent residential, retail, and commercial landlords for a living, doing lease enforcement actions. I do not know the landlord & tenant laws in Ohio so I cannot speak to that issue but you should speak to a local L&T attorney to know what it takes procedurally and what it costs to remove a tenant. In DC it could take me a year to get rid of a tenant. Can you afford to float the mortgage for that long??
