Rick has some really good advice. From experience I would avoid putting all of your money down at once. Even though you may get a discount it is not worth the headache if you ever want to leave the school or if your plans change. Take your time choosing and if the owner seems very pushy, don't get suckered in. It's your money and I would choose very carefully especially with the amount you will be spending.

Large vs small it is all what you make of it when you are there. Network as much as you can where ever you go.
