How to Vacate Newly Purchased Home

[Monish Lillaney]

Hey all, I'm about to close on a three family owner occupied dwelling on 01/31/20. My lender has given me 60 days to move into one of the units.

I currently have three tenants each paying about 60% of market value. I'd like to have the entire home vacated for closing allowing me to renovate all three units, move into one, and rent the other two at market value. The tenants are all TAW, and were issued a Notice to Vacate by 01/31/20 in November 2019. 

My attorney has said that I can have the Notice to Vacate assigned to me at closing (since it was issued by the owner who is selling me the home) so that it acts as though I issued this notice. Does that mean that I can start the eviction process (assuming I don't accept any February rent) legally 7 days later? (February 7th, 2020)

How can I get them out as quickly as possible since they are TAW? I understand that leases run with the land, do Notice to Vacates as well? 

This is all in Massachusetts btws

Thank you all!!  Hope someone is a bit brighter than myself in the legal side of this
