Lots of new grads seem to go for Clapham or Balham, which can make the place seem like an extension of uni. However, rent prices aren't particularly cheap - around £700 a month if sharing, or £1000+ on your own. That does put you on there Northern line, but at peak time it's horrible. You could save money by going further south or east (or both), but I'd suggest having a good look around before signing up to anything.If you want to be very central, look east of Liverpool St, but as with SE, it's a mixed bag.Anything West in zone 1-2 is going to be pretty expensive and Fulham and the like can be a long commute. Chelsea/South Ken would add in the Piccadilly line, but unless you want a big house share, you'd probably too stretched on your current salary.I haven't lived in North London, but a number of colleagues are in Angel/Islington.Do you know which industry you're working in? FS is more likely to be London centric, so you may want to spend a bit extra on your home, whereas if you think you'll be heading to Euston/Heathrow etc every week, then I'd suggest keeping living costs as low as possible.Good luck
