I'm inclined to agree with everyone else that has posted. I lived with my ex-boyfriend and my best friend in a very small apartment, and while it wasn't a bad living situation, I definitely had to work overtime to please both parties, and this may or may not be an added stress that your boyfriend would be willing to undertake.
However, my ex and I did break up after living together because he went back to school and the distance was too hard, we had grown apart while living together, more as best friends that just didn't see eye to eye anymore. (just my personal experience)
I have also lived with other guys (try 7 in a house with one other girl besides myself) and it was fun, but we were much younger and I wasn't involved with any of them. It was definitely difficult to clean up after them, and had roommate fights with them from time to time (we all did).

My point is, living with other people can be difficult, no matter the circumstances and why add relationship drama to the mix? (not that there would necessarily be drama with the bf, but the potential is fairly great)

It might be better to live with some other people to split the cost in the meantime and spend time together on the regular, see how things go, he's also in grad school and you're just starting out after graduation. I know it's been a difficult transition time for me and my friends and sisters since graduation, so strengthening your relationship and working on yourself might be for the best.
Good luck!
