Lease Agreement for Inherited Tenants

[Rafael Lopez]

If I purchased a property with tenants that don't have an existing lease agreement with the former owner are they obliged to sign my new lease agreement when I submit it to them? If they don't want to sign what can I do?

This would be for a new purchase in Ohio. I haven't submitted an offer because I'm unsure of this would play out. I'd appreciate the feedback. 

Thanks,

Rafael Lopez
