This may be a bit late or irrelevant now but due to my illness, I was offered to stay on campus for the next year. I struggled to find people to live with and then recently I did find people to live with and whilst we get on, we rarely speak and we're staying in a house with an agency which isn't very good (takes them ages to do any fixtures, lots of hidden fees) and I don't know how well I will get on with any of the people in the house. Saying this though, it means I'm covered for next summer (even though I can just move in with randomners in town or stay on campus over the summer) and it means I am close to town and close to my friends living round the corner from me. However, I don't know if it's worth living in town living with people I hardly get on with just for the sake of living in town, when I could live near my lecture halls and the library and be able to do my work efficiently instead of worrying about bills and risky agencies. Then in third year I can live with people I actually get on with well that had already sorted housing before I met them.
Usually if you're put on campus for a second year, they will accommodate you with postgraduates, other health students or reps. Plus you can sort of live the life of a fresher again, meeting brand new people and being invited to parties as well as parties in town or wherever everyone else lives. It's easy to feel left out since all your mates will live all over town, but at the same time you can't give up living somewhere that is safe and all the bills and fixtures are sorted for you asap, especially when there's so many agencies that con students out of so much money.
It's a tricky decision but the way I look at it is, your friends will probably adore living in town for a while until it starts to get colder and they're having to travel in every day or travel in to use the library. A lot of people will appreciate campus accommodation so much more.
