Caporegime
As I said in an earlier post, it's not really possible at the moment (girlfriend doesn't have a car, would take her 2 hours each way on public transport to get to work). I also can't move out of my house at the moment because of the house market, it would never sell (it took the previous owner 3 years to sell it!).
Somehow I doubt that would go down well, I'd expect the landlord would insist on paying the same as the other housemates. She actually said she would charge 'at least' £5 a stay, suggesting she still doesn't think I'd be paying enough...
Surely her living with you and getting a car would be cheaper than her and you paying for individual rent/mortgage.
