Seeking advice for potential eviction

[Vincent Carroll]

Greetings,

My wife and I (and our young son) owner-occupy a duplex,  and we have a tenant (family) next-door who we inherited when we purchased the property last year. They are presently on a month-to-month lease, and although they pay their rent, they are not desirable Tenants by any means, and therefore we gave them notice on Feb. 1  that way we would not be continuing their lease, effective March 31. So essentially we are giving them twice as much notice as required by law. Since giving them notice, we have heard nothing, and are concerned that they do not plan on moving. 

I'm seeking advice on how to handle this somewhat touchy situation, as we have to live next-door and these folks who are fairly strange, and we have had some contentious interaction with them regarding their smoking in the property which is a violation of the lease. Should I check in with them in the near future to confirm that they received our notice (which was sent by certified mail), and inquire if they have set a moving day? I feel that we cannot be flexible in terms of allowing them to stay any longer than the end of the month.  If, when the time comes, they do not move out, I feel that we must begin and evection immediately, which will be our first eviction experience as we are relatively new to landlording.  Wondering how to best navigate this somewhat tricky situation. 

Thanks  in advance for any advice!
