If you're tired of London that is because it's overcrowded, it takes forever to commute, it's noisy, it's expensive and it's required of your to get at least tipsy every Friday.
Most londoners don't consider that a plus if it's in the middle of nowhere with no culture or anything to do.
Everywhere has a culture. It's more accurate to say you don't appreciate other cultures.
When I moved out to zone 5 from zone 2 (well technically 3, but my best route was get the bus to a zone 2 station), the combined cost of the premium on my travel card and mortgage/insurance/other costs was still lower than the 2 bedroom flat we used to rent.
The thing is, there is nowhere "cheap" in zone 1 or 2 that people with options want to live in, but once you get further out, you have a lot more choice. I certainly could end up paying more - I'm within a short bus ride from some of the most affluent areas in England (parts of South Croydon is full of large estates that are dirt cheap by London standards, yet within commutable distance to central London).
The quality living for me is far higher here, and the travel distance to central London is low enough that when I need to commute in I often had shorter commute than people who lived in zone 1 or two but happened to live on the "wrong" tube line.
We're now 40 people and we're struggling to hire developers fast enough - we mopped up the local talent, and we're now hiring EU nationals mostly, as while we offer a relocation package etc., the cost of living here is a fraction of London - but folks coming from London usually want a London salary - and aren't willing to negotiate. So they stay in London and moan about their rent trap, while most of our employees now own their homes.
Shrug. Inertia's a bitch.
