What is the process to serve a 30 day notice? Can it take longer than 30 days? What do I do if the tenant doesn't move? I am a new owner of a 3 family in Massachusetts. I've been living with my sister since my niece moved out a few years ago. The arrangement was supposed to be temporary until I fixed up and moved into one of the apts or my boyfriend and I bought a house. While my boyfriend and I were fixing up the building, I commuted from there a few times. Commuting from the apt added an extra 20 minutes to my morning commute and an extra 40 to my evening commute so I decided not to live there. My niece and her boyfriend broke up so she's back home and I'm living out of boxes, sleeping on the couch. I need a place to live and my only option right now is to move into one of the apts. I plan on sending the 1st floor tenant a 30 day notice to end the tenancy, they are tenants at will. They failed to pay me this month's rent and are now avoiding me but I need a place to live more than I need their rent money. Can their non payment of rent make this process more difficult?
