State Specific Question About: MASSACHUSETTS (MA)

Hello family and hoping this post finds you all well and safe,

I had a prior post about me asking the unit to my tenants, month to month tenants, i have some other plans (that is what i told them), the real reason is that my sister in law, her husband and 2 kids came from my country and don't have where to stay, haven't found an affordable place (her husband is working), so we offer rent them our unit... Long history short, 2 month has gone by and 11 days... And tenant hasn't move out, they are a young couple with a 2-3 year old boy, she is currently pregnant and had been home due to complications, they might have an early delivery due to the same complications, question is, i gave them more than enough, i am almost certain what is next step, but i want to confirm... Should i evict? Even if they pay this month? If July 31st come and they haven't move out (it seems that is what is going to happen), if they pay me (i haven't had any issues with payments), should i take it ?

I don't really want to go to eviction, but my sister in law an her family are living with us, sleeping in my kids rooms, they need their space (they ask for it, not we kicking them).

MC they are month to month, i gave them 60 days instead of 30, now we are in our way to 90 days. Yes we are on decent terms, when we gave the letter asking for the apartment, they even mentioned that they were thinking into look for an apartment (or that they were looking, don't remember the exact wording ), due to the wife pregnancy, they will be 4 now and would need more space... I set the day well in advance, i am ok if we need to go to 4 month (as the last option if we really MUST) but no more than that.

Busy Yes i said that in the other post, relatives are providing rent and i am setting it aside.

Still Learning they will go to a early labor and delivery in 2 weeks, she will be on her 37th for that time, so she must be 35 now. Since this conversation, we just talk to our relatives about it, we are going to help them to look for another apt in case this goes way over, i can wait until September if we must.

Small Potatoes, this is my wife's sister, they were paying too much at the other place and far away from us, it was for all better interest if they move closer, for the kids while they get situated (husband started working, not much hours, my sister in law is not working yet, kids didn't started school, in the process for next school year), no they are not demanding anything, they are patient.
