Good luck :) If you want roommates to help pay the mortgage, you should buy something as close to the University as possible.

It does not take that much to be financially free (a few paid for properties), and if you're able to purchase a property every 2-3 years and continue living with roommates, you can completely change your life in a relatively short amount of time. 

I got my start in real estate back in 2012 when I bought my starter home and thought it was too good to be true to have roommates pay the mortgage.

I also have gotten quite a few roommate situations (some of which worked better than others).   

And does anyone know if both tenant and landlord can allow multiple bank accounts on either side in these programs (for example if two roommates are splitting rent and want to pay from two accounts)?

I know when we were looking for rentals (private landlords only), they refused to allow us to have roommates due to the unrelated tenants law, as they were unwilling to take on that risk.

I could find a place near Johns Hopkins University, live there myself with another 1-2 roommates, and when I leave a year later, I can continue to rent it out as essentially student housing by swapping out one tenant at a time.

In Buffalo, when I was in college, I decided to buy a 4 bedroom single family house (thanks mom for co-signing) and got 3 of my friends to move in with me as roommates.

That's why now I'm looking at only 1 property on a lot with at least 3 rooms so that we can indeed get a roommate situation (don't mind giving up some privacy now to get going in the long run).

You can advertise looking for roommates or rooms for rent on several websites including Facebook marketplace.
