Cant comment on the UK but it is near impossible for millennials to get on the house ladder when I am (Vancouver), unless you have access to inter generational wealth.
Converting amounts into sterling for reference.
The average 2 bedroom apartment is ~£2,200 per month to rent. The average monthly salary is ~£3,100 so, if you’re renting, you can expect to pay more than two-thirds of your monthly income on rent alone. Saving is not realistic, Netflix or no Netflix.
If you want to buy, even a small (800 sq ft) flat will cost you around £400,000. For an actual house (even a small one), you’re almost certainly looking at north of a million.
Prices have more than tripled in the last 20 years, while wages remain largely stagnant. Most people who owned a home more than 20 years ago are now millionaires.
DP and I have a combined income equivalent to £120,000 p/a but even then were living in a cockroach-infested 1 bedroom apartment (as in, you’d see 50-100 roaches per day) until our mid 30s and, even then, we needed family to contribute about a third of our downpayment for a modest home, 1 hr outside of the city.
