When discussing graduate school and PhD programs, I had a professor mention to me that some schools will not accept a student because they do not anticipate that student accepting the offer. This stems from the fact they have limited spots and want students to accept instead of having to go through the process of reaching out to students on the waitlist, etc. Basically, schools give offers to students who they anticipate (or hope) will accept their offer.
That being said, would it make sense to make it apparent in my SOP that I would accept an offer from the school if it was presented? And I do not mean in a tacky way which would read like I wrote it on the SOP for every school. I mean make a compelling case for why this school is the best place for me and then add a sentence like, "I believe [your University] is the place I would be most successful/happy/focused and given the opportunity to attend I would accept" or something along those lines.
Additionally, is it fair to mention a reason like that if it is not expressly academic (in addition to the academic reasons, of course)? For example, location is very important to me and would strongly impact my decision about where to attend.
