I used to live in Warlingham so Croydon often comes to mind :-) You think that's weird though.. you try bumping into people from Lincolnshire on here (where I live now). It happens!
Well I wasn't earning anywhere near £60k when I moved away. But it's not an unreasonable salary for soho creatives or a random job in the 'city' with 5-10 years experience. I used to live in Clapton about 6 years ago just off the 'murder mile' it was a bit like living in 'the wire', but we were younger and didn't care. We shared a two bedroom basement flat between 3 people and the rent was about £900. The second bedroom didn't have any windows. I'm sure you can find rents below £1300 for two bedrooms if you go further out. But you pay in train fares and commute time, especially if your office isn't central. You need two incomes for sure, but when you have young kids all of the second income goes on childcare as both earners need to be out of the house 11hrs per day. That's why we recently gave it up and moved to the country. Is that why you're in Lincolnshire?
