You have several good acceptances that are affordable. You don’t need to twist yourself into knots trying to make the finances work at other schools (“marriage trick”?!). Prestige of undergrad school isn’t very important for premed or engineering.
I don’t think you should stretch the budget much beyond the $160K savings. If you work really hard, you can probably do the $10K/year job earnings, but I’d not plan on anything more than that. Premed and/or engineering curricula are demanding and you need the option to step back from working while in classes. You might also need to spend time volunteering rather than doing paid work as a premed. Med school is staggeringly expensive so it’s wise to minimize undergrad costs.
That leaves you with the schools that came in below $50K:
PSU [22k/yr] – admitted major not listed?
Pitt [40k/yr] – admitted major not listed?
Delaware [45k/yr] – engineering + honors
[Temple][ Free] – engineering + honors
[Purdue] [41k/yr] – engineering
[UC Irvine] [40k/yr] – engineering
[Drexel] [50k/yr] – engineering + honors
Rochester [50k + 5k grant for research] – neuroscience
How did you get Irvine cost so low as OOS?
The next question, which is paramount for your school choice, is do you want to major in bio/neuro or engineering? You say your area is computational neuroscience. For that field I prefer the track of engineering/computational major with neuro minor/electives.
Getting the grades and prereqs you need for med school is hard with an engineering major, but an engineering degree is an excellent “plan B” if you don’t go to med school for whatever reason. A neuroscience degree is not really employable, and I only recommend for people who are certain they they’ll do a PhD or med school.
At most schools, it’s easier to change major from engineering → life sciences than the other way around. You’ll have to check with the individual schools. What majors were you admitted for at Pitt and PSU?
Is there any particular reason Temple isn’t the winner here? You’ve already worked there and seem to have loved it, yes? Unless one of your waitlists comes through with incredible aid, I’d find it hard to turn down the Temple offer. Save that $160K for med school or for a zillion other things.
