I am doing summer school at my college so I cannot go back to my home town. The place I live closes over the summer, but luckily I have some good friends that have an apartment. There are 4 of them, none of which will be living there this summer. I need to ask them to stay over the summer (which they will say yes to), but should I offer a portion of the rent? Keep in mind I am a (very) broke college student, but I don’t want to take advantage of them. Any thoughts?
