Living with bf at 16!!

I'm 16 and my boyfriend is 19, he has a job and I'm finished school and currently looking for a job, and last night I was over his house and we had a bbq with his parents. We had a few drinks and his mother suggested we try and find a house together, and she will help us find one. I told my mother when I got home and I was surprised when she agreed. Does anyone else think we're far too young or just me? But if our parents are okay then I guess what's wrong with it, but I don't feel grown up enough or ready to have my own house at such a young age, help?!?
