I think a combination of access to the pike and new or redone houses in their price range probably knock these communities out.

All of what you said about Longmeadow is true but the houses are mostly on the older side since the town was built out by the 1970s. Getting an updated or new house in that price range might be difficult.

East Longmeadow and Wilbraham have newer houses but highway access can be difficult. They are also less walkable compared to Longmeadow but have more of the farm feel. That being said, they are also more politically conservative.

Based on the experience of family members OP’s age, I think Grafton is probably their best bet.
