Moving to Newton - Family of 5 expenses

Hi Everyone, Hope you are well. I am keen to get your kind help. I've been offered a role in Boston, which will require from us to relocate to Newton. I'm not that familiar with the expenses, however I tried to use ChatGPT and public information calculating our future expenses. Can you help and provide your view? Have I underestimate or overestimate any of these items? Have I missed anything?

Thank you so much,
