Congrats jpn809!
I think Columbia is really turning around in terms of reputation, but it is still very expensive. If your heart is set on Yale, why not reapply next year?
But -- I think -- you have to really weigh how much you want to go to Yale vs. how much you want an MFA. Yale takes so few people a year, it's quite random. You could reapply again and again and not get in, and perhaps some other really wonderful schools would be a good fit, too ...
You have to go with your heart, I think. It would be hard to be paying a lot of money to be at Columbia and wondering the entire time about somewhere else.
Good luck!
