How much did I mess up my chances of getting into college? [college calculus 1 B grade, IB math AA HL A grade; MD resident, 3.967 GPA, top 10% rank, 1530 SAT, <$50k, civil engineering]

I tried to post a match me with more relevant information, but it got removed because I had already posted one a couple of months ago (if I can figure out how to post one without getting it removed I definitely will). Iowa State and Princeton are affordable according to their NPC, but other than that, I’d have to take out a loan. I’m concerned about affordability, but the problem is I can’t find any schools that are low cost that I would actually want to go to (I’ve received Alabama and WVU a lot, but I would rather not go there).
