@ImplementingTheDennisSystem If you don't live in the SE but your house prices are similar, what exactly is your point?
FWIW I didn't 'choose' to live in the SE or have any interest in it. I arrived here as where I used to live didn't have the type of jobs I was qualified to do. So I got on my metaphorical bike and moved to get a job. It was that or be unemployed, or taking a low wage job, not a profession.
The reason it's mentioned here is because it is actually the most expensive part of the country, with maybe some parts of N Yorks and Cheshire keeping up.
It's simply a fact that excluding some pockets of the north and NW ( Harrogate, Yorks, suburbs of Manchester etc) the SE in the commuter belt is very pricy.
Our mortgage was £700 a month 15 years ago.
Here, the cheapest 1-bed flat is over £200K. Season tickets are £5Kpa and station parking close to the same.
That's why posters refer to the SE. It's called the Cost of Living :)
