I would exercise caution with anecdotes like this. Assuming that we are talking about only merit/talent awards, it is certainly possible for this to occur, but it depends on which schools are “most expensive” and which schools are “cheapest.” For example if your “most expensive” schools are in the set including {Northwestern, Carnegie Mellon, NYU, Boco, Michigan, or Syracuse} and your least expensive schools are in the set {Texas State, Montclair, Coastal Carolina, Florida State, or Wright State}, this is going to be highly unlikely to be true. Texas State and Montclair offer in-state tuition for MT students, FSU offers in-state plus scholarships for good grades and test scores, and Wright State offers substantial R&B discounts which drop costs to below $20,000 and possibly below $15,000 per year for tuition plus R&B. Those numbers are very difficult for schools with “list prices” in excess of $45,000 to match or beat.
My D received several Presidential Scholarships and talent awards that moved her numbers for some schools fairly dramatically, but in no case did very expensive schools ($45,000+) move below $24,000 per year, while some $25,000-$32,000 schools moved to less than $15,000 per year. She received some excellent scholarships from expensive schools that discounted tuition by more than 40%, but that only brought the costs down to the mid-$30’s.
Her cheapest school was less than $10,000 after scholarships, but the list price began at less than $20,000.
A “most expensive school” ending up being cheapest is most likey to occur if the differential between highest and lowest is not too dramatic.
Of course, anything is possible. It all depends on what your set of schools are and what the academic and talent levels of your student are.
If need-based aid and/or loans are figured in, then the situation will become more variable. Our EFC was too high for need-based aid to be a factor, something that I believe is fairly common on this forum.
This thread contains estimates of cost after average merit/talent awards (assuming no need-based aid or loans):
