Would you rather live in a quite nice average size house on your own like a proper grown up that you paid for by yourself, with your wife/kids.
or
In an extremely nice house on many acres, swimming pool, 5 car garage, etc. with your wife/kids, perhaps even a small farm BUT... your MUM lives with you. She would have a separate "granny flat" and would travel most of the year so you might not see her, but you still be living with your mum. Or technically she would live with you.
Your household bills would stay the same for both scenarios.
