Problem tenants on a month to month lease

[Michael Filppu]

I purchased a duplex a year ago with inherited tenants. One moved out immediately, and I took that opportunity to fix up that side of the duplex. Now it is fabulous and rented. The tenants in the second side smoke indoors, continuously pay rent a little late, and a contractor is telling me their side is not safe to live in. I sent a certified letter giving them 30 days to move out. They are not receiving the notice that I will not be renewing their lease. What are my options at this point? They say they are willing to meet up and talk about it. I’m willing to offer cash for keys. What can I do if they will not receive the notice?
