Having issues with my first floor tenant

[Edward Dones]

Ok BP family finally got my first house that I will be house hacking in a few (hopefully) but I'm having a issue with the first floor tenant. I became the landlord on January 31st and on feb 1st my tenants in a 2 unit had to pay there rent. 2nd paid no problem but my 1st floor tenant is upset because she has to leave, she's on a month to month no lease and didn't pay her rent she has to leave but I feel like she's going to give me some issues getting her out. My question is what steps can I take for her to move without heading to court for a eviction process. Also my second tenants rent covers all PITI and water bill and is very happy with me being the landlord since I already having a few things fixed for that the other landlord wouldn't do for her. I'm in the western Massachusetts area as well FYI (Springfield Ma)
