@Sportsman88 I can only speak from personal experience and we found Columbia financial aid to be outstanding. The only major difference between its financial aid and Harvard’s is that Columbia does consider home equity.
Our NPC was nearly identical for Harvard and Columbia. S graduated with zero debt and our expected contribution was very manageable and lower than we had anticipated. They even waived the summer earnings expectation for two years running so he could undertake international internships. I was also surprised that they increased his grant to cover his health insurance.
