I'm doing the same exact thing, actually. I am 24 and I've lived with a friend of mine from college for two years. In the interest of saving money for grad school, we're both moving into my parents new house.
We're still in the process of moving everything, but I think it will be worth it to not accrue any student loan debt. Fortunately, I like my parents and we get along great.
If the moving thing would just go ahead and end already, I think I would be fine
