UK wages are not great.
UK wages are not great.
People overestimate how much senior devs in the UK earn, even after knowing they're not well paid, my usual response to hearing we should be earning £90k+ is, "well give us a job then"!
What sector?
First, you'll take home slightly over half of that net of various taxes and deductions, but let's be generous and say your take-home is 200k. You live very frugally, don't go out, don't really buy anything and keep your costs at 50k a year, including rent (!). That leaves you with 150k a year, so after 5 years you have 750k. This allows you to buy a modest 2-3 bed row house with a postage stamp sized garden in one of the less desirable areas of the city.
If you want something that doesn't look like a shed, you are looking at 1 million pounds and up, more like 1.5 million. If you want in a nice area and large garden, make it 2 million.
The only thing I can think of that would even come close to making a difference is having children. Then all bets are off, they can cost as much as you like.
'Inner London' and it goes up to £876K
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.

There is not being able to afford something and then there is not being able to afford exactly what you want.
