MA Assessors are only required to re-assess every 9 years, according to one conversation I had with a town assessor department head.
In Falmouth, they operate on a 3 year schedule.
However, they often only drive by, because in MA if you don't let them in, they can't assess what they can't see.
I would contact a local real estate professional to help with this answer and to save time and money.
(I'm on the Cape, but I can help you choose a local pro from our Boston Office on Newbury Street if you want help doing so.)

Also, while I have been a VIP+ - over 1750 questions answered, over 250 Thumbs up and best answers combined - I do not try to mantain VIP status anymore.
Maintaining VIP is status on this site does not privide benefits to professionals and it is even numbered backwards.)
