Depends when you bought - our house is probably worth about 600k now and household income around 50k. Mortgage under 200k, just over 1000 a month.
This is in London, but a similar house in most of Surrey would cost more rather than less.
BIL up North has a larger house probably worth 200k but the chances of me and DP both getting jobs there (Yorkshire) to pay for said house are minimal. Just as well we're happy here (and been insulating like mad...)
All the jobs I've ever had had a London weighting of about 1-2kpa. Whoop-de-doo. And no SouthEast bonus. My work do have regional offices around the country - the ones in Surrey and Reading are crap because we can't pay enough to keep anyone with a brain cell so average retention is under 6 months, whereas the ones in the rest of the country, especially Cumbria and rural Wales have dedicated staff most of whom have been there over a decade and do a fantastic job. Given pay freezes I don't see the situation improving soon.
