I got into Northeastern EA. I haven’t committed yet (though I really want to), because though I was given a good offer, I would really need another 2k a year to seal the deal and put the price perfectly at the top of the range my family feels comfortable paying.
What do you think my chances are in receiving anymore financial aid from Northeastern, and if anyone has any suggestions on how I go about this (besides just emailing my financial aid office), that would be greatly appreciated! 
Lol good luck. The net price calculator told me 23k and my offer told me to pay 50k. No thanks Hah. Not sure why they’re awful with aid. I emailed but they said they usually give the best offer they can give upfront so It’s very unlikely it will change.
Has anything changed since you submitted you original FA application in terms of parental income etc…? Is what you received substantially different than what you expected to receive, I.e. there’s an error in computing your FA?
While unlikely, there is no harm and there are cases of pleading your case being improved. Dropping that $X would mean you committing etc can’t hurt either. The NPC being inaccurate for others doesn’t mean stingy for all cases, but rather that the formula doesn’t match for everyone. As someone who got nearly a full ride in FA, I can tell you that it’s not unheard of.
The general tough cases are that Northeastern counts home equity, so owning a home significantly hurts FA offers especially compared to the FAFSA EFC. That and business ownership can make it very unpredictable.
