Yes. All of those (except maybe for ranking) should probably factor into your decision. With that in mind, it totally makes sense to hold onto your acceptances until fin aid packages go out. Now I would never recommend going to a school you hated just to save an extra $50,000, but at the very least I think if you have any inkling that you might like a school that's accepted you, wait till the fin aid comes out so you know all of the details and you can make the best-informed decision possible.
As far as further interviews, I guess I'd ask what exactly it is you like about UTSW. Is it just location/tuition/prestige, and you don't hate the environment? Or did you really LOVE the school and come out of it extremely excited about spending four years there? If it's the latter, and you have difficulty visualizing a school that could just blow that experience out of the water, then I don't think anyone would blame you for turning down a few interviews. (But frankly, I don't see how your parents can complain when they made you apply to 69 schools 😉 Since money seems to be almost no issue for your family, it might not hurt to just go and check the schools out; couldn't hurt, right?)
I really liked everything about UTSW... the location (I, contrary to most of the people in the US, like Texas, and could imagine myself living there), the cost is unbeatable, and it is more like saving $100,000
😱 of debt... The prestige is meh.... no one I know, knows where Southwestern is, except for my uncle in Dallas, who really wanted his son to go to UTSW... and I think I would like the environment, because as much as I hate it, I thrive under competition, and I need the graded system as a motivation factor... it is just right now I am kind of afraid how I will fare, because my grades are slipping due to my lack of caring, and I dunno... med school is supposed to be hard, but I do not want so much stress, that I am completely bald by the time I am 25 and I graduate med school...
😱
I dunno... if I did not have UTSW, right now, I would be booking a flight to Baltimore for orientation in August, because there was just something, I am not sure what, which just completely blew me away. I actually applied here to appease my father, since my sister is in Virginia, and it is pretty close by, and I got an interview invite a week after I submit my secondary, my interview was basically the interviewer trying to convince me to come to Maryland, and how it is a great place, and I got my acceptance in exactly three weeks! I at first was so surprised that so many people were asking for the Maryland in the Lucky Interview thread, and when I went, I realized why...I really liked the school and the location, and I am so confused...
Oh and my parents want me to stop going to interviews, because money is a factor for us. I am actually middle of middle class, not upper class...
🙄 My parents do not want to waste money for me to go to schools which I might not go to. The only reason that I had to apply to so many schools was because A LOT of my dad's coworkers kids did not get into medical schools, and he was afraid that I would not get in either... plus I have the 3 strikes against me, considering I am an Indian male from California, it is supposed to be harder for me to get into medical schools...

Sorry for the long posts...
