I'm 18, and live with just my mum. I'm actually in the process of buying a house with my mum o_O. The idea is just to get on the propperty ladder while I can, and maybe rather than me move out from our new place, she will move out.
There is just no need for me to struggle on my own moving out, I have yet to come across a lady who I would even consider moving in with, and I just don't have the money to live comfortably.
