So I just came back from Stony Brook, and I loved it! Also, I talked to multiple grad students (I actually even talked to my Uber driver about it lol) and it is definitely possible to find an affordable option. It's definitely not super easy to find a cheap place, but most grad students in the department live in Stony Brook (off-campus), or Port Jefferson paying under $1,000/mo (most people said they pay $700-$900/mo including utils). That being said, they all said that finding an affordable option that's around $700-$900/month would be much easier if you can find one or two people that you can room with. One of the grad students said there's a Stony Brook undergrad/grad housing group on Facebook, and some people in the department found roommates and living options there. Also, some people live in "basement apartments" and I asked what that meant cus it sounded very sketchy and wrong. They said some houses restructure their basements and make them look like apartments (kitchen, bathroom and everything). I had two concerns with this: 1. Will I get in any legal trouble if I decide to choose this option? and 2. What if people upstairs accidentally (or intentionally) come into my "basement apartment"? The answer to the first question' is no; if anyone gets in trouble it'd be the landlord. The second question shouldn't be a problem either, since they restructure the basement such that nobody can access the basement from inside the house (and vice versa, you can't enter the house from the basement).
I don't know if this information is helpful enough. If you wanna know more, you're more than welcome to pm me. I really loved the visit and it's a great fit for me. I still have another visit to make in late March, but I'm almost certain that I'll choose Stony Brook over the other (mostly due to research interests). @thevphone @Arkhy @goatorsylvia I hope you guys find this helpful!
