I'm a SAHM at the mo and DP has a fairly good job (earns just over 50k) but with our rent and bills we have pretty much no money left over. We run a second hand car; went on a very cheap, off season, UK hol; get lots of hand-me-downs or second hand stuff for our boys and hardly ever buy new clothes and suchlike ourselves. Things like a baby-sitter and a night out are very, very rare treats for us and although I realise that compared to most of the population we are wealthy and I'm not unhappy living fairly frugally I'm interested to know how much you all think is needed to live a comfortable life in London.
