So, basically, if you’ve done your due diligence to figure out your cost (as someone suggested above, talk to FA) and feel it’s affordable, then feel free to apply ED. My bet is that if you are in need of financial aid to any great extent, then the benefit of applying ED is probably negated. Lots of ED (or even RD) applicants out there that are going to be full pay.
My personal feeling in reading about ED on CC threads is that it’s a bad idea unless you can simply pay the full COA. Some people don’t seem to realize that if the acceptance rate doubles when applying ED at a school, and you have 0% chance of getting in RD, then you STILL have 0% change during ED.
