It isn't a particularly high salary for an experienced developer here in London, but struggle is an exaggeration. The majority of people in the UK and even central London are paid less than this.
I doubt that’s true for professionals working in central London.
Where would you live on that much money? You’ll spend your life and most of your money commuting!
Live in Zone 3, spend maybe an hour and seven quid a day on the tube? London rents are outrageous, but not so outrageous you can't afford to live there on £50-57k.
You’re supposed to not spend more than three times your salary on your house, according to most lenders. So that’s £150k. Are there many houses that cheap in Zone 3?
No, that's why a vast proportion of people can't afford to buy.
No, you'd probably have to rent unless you can get a massive deposit from somewhere.
That 3x thing is laughable where I am in Auckland. I assume other places have it worse, unless their wages are much, much higher.
The limit is about 4.5x, and that’s on top of any deposit you have saved.
