To echo the others, Brandeis for Tufts as they have merit…then Bentley/Babson are a bit more business oriented and math fits right in.
Since you have Pitt why not UMASS or UMASS Lowell to be closer to Boston. Not far area is UNH and then there’s Bryant.
You have both urban and rural - so not everything you have is Boston. Look at below your top 30 LACs (and not all offer) for merit aid. For example, Franklin & Marshall doesn’t offer merit.
If you want to pay, it’s not to say you won’t end up in your reach schools - you just need more options. You list the Cuse - so how about an American or Denver?
Boston is awesome - and you can intern/live there. You can still go to college there too - just give yourself alternatives is what people are saying - and find out what you can afford because saying no constraints but I’d like merit likely means you have constraints. Talk to your folks.
PS - take a look at Macalester - it’s not Boston…but it is urbanish, a LAC, and offers merit.
