I don't think it matters who the new owners are. If a person or other entity purchases property that has a tenant they typically continue with whatever lease or rental agreement that's in place. What difference does it make to you who owns the house you're renting?
Probably not. IF you have a lease, you are likely entitled to complete the remaining term of the lease. If you are month to month, then you could get notice at any time and be required to vacate in the time allowed by the laws of OH.
Look up the landlord tenant law for Ohio for a complete explanation of your rights and responsibilities as a tenant.
