Trying to advise DD who is going to rent her first apartment with her long term boyfriend. She's going to be doing a masters, whilst he works as a junior doctor. The city they're moving to is cheap.
Her scholarship from uni means she can budget up to £7k on rent, and still have a good lifestyle funded by the rest and money from us (inheritance for that purpose) in case of emergency, her savings.
He will earn about £1800 a month after tax and pension etc.
I was always advised when I was younger, 1/3 for rent and bills, 1/3 savings, and 1/3 for living.
They've seen some stunning, modern high rise apartments for about £900-1200 a month.
