Depends where you want to live... but £200k a year won't be enough to afford a house in a fasionable area, if that's what you mean. Forget Notting Hill, for that matter don't even think about Clapham... £600k won't even get you a 3 bed terrace in Balham. Stay on the Northern Line, perhaps you can afford to get off in the somewhat unlovely area of Tooting - ?Even sky high salary = modest house in modest area. One built for a City clerk, perhaps. So you either move out or go for something smaller (depending on age and where you are in life) or you live somewhere unfashionable. Such is London. Still worth living here though.
