By purchasing the property, you can get an assignment of the lease so that you become the lessor. If you want to offer the existing tenants an option, simply ask them if they want to renegotiate the terms of their existing leases.
I’m in the process of negotiating not one but two l/o option deals with tired landlords. Both properties as it turns out are twins and both have existing tenants. Have no idea how/what to do about the tenants(one is on a month to month and one has a few more months existing on their lease)
If there has been some discussion on this topic before, I would appreciate it if you could steer me to the right thread. If not, what is a good strategy for dealing with the seller and tennants.
