Smart Money. After high school, I’d love to move into an apartment with a bedroom with my boyfriend. Therefore, I would get a roommate if there is half the battle. (We have already agreed that) On average, what is the cost of rent for a one bedroom? Also, what is the average cost of other expenses? Air, electricity, water, food? I know it depends on person, but only on average? Another question, I know I’m asking a lot, but what I have taken int account? Thank you!
