A friend is making about £180k / yr in London, and they bought a house recently in London. I think that's a lot, and his wife also makes a similar amount, slightly more. That seems to be the minimum, otherwise you're a renter for life. Pretty nuts.
Outside of Finance that's high for London.
That is an extremely high salary, and very far from the minimum required to buy, even on your own. A dual £350k income is truly astonishing. You could buy most houses in London in cash after saving for 5 years.
Median property price in London is £542k [0]
Assuming a 90% mortgage that's 487k mortgage
That's two people on £70k each at a 3.5 multiple. £60k at a 4x multiple.
Two people on £180k would get you a £1.5m house, twice the average semi.

London property is expensive, but £180k is a lot more than the "minimum". I am on half that, and I managed to buy.
