Less clear than you might think. Choate isn't as rich as Harvard, but it's still on a tier with, say, Wesleyan (for context, not as a fair comparison), with the finaid apparatus to match. They are absolutely capable of letting you "afford" to attend if they want you there, not quite orthogonal to whether you can afford $250k/year (more than Harvard sticker price anyway) but maybe at a 60-degree angle or so.
