Have you made “bird in the hand” type decisions before? Are you a “could’ve, would’ve, should’ve” person?
If you don’t have financial considerations, then think about your personality. For example, once my D19 makes a choice (to take a certain class, job, trip) she doesn’t look back. She embraces her decision as the right thing, meant to be, and goes for it 100%, which made her a good candidate for ED.
She had three academically strong schools she really loved. We revisited and a favorite emerged. It was not the most prestigious or highest ranked, but she felt very comfortable and happy there, so, she applied ED and was thrilled to be accepted.
She is thriving there, and completely sure she chose the right school.
Personally, I think she would have felt the same way if she had decided a different school of the three was “the one” and been accepted. She primed herself to look for the positive and she committed wholeheartedly, which made it unlikely that she would have regrets.
I would ask yourself whether you have this type of outlook before applying ED.
