There were additional issues like the logistics and upfront costs of a cross-country move, as well as the timing of aid disbursements and expense needs. Which I neither had the savings nor the cashflow to confidently support, nor anyone to lean on temporarily for it. While there were plenty of unknowns for the state school, they were manageable enough for me to be competent in my ability to handle them and close enough to my personal support network if things went south.
Many schools do in fact have the ability to address such needs. I just didn't learn was a possibility until after the fact. For anyone else that happens to be in that situation, I'd strongly encourage doing what you did and taking the Ivy offer. There will be sufficient support to accomodate your circumstances. It'd just be nice if the schools themselves improved their offer letters or follow-up collateral to address the concerns/needs that are likely for those which qualify for a zero'd out tuition or whose application/FAFSA documents indicate are a first generation college student.
