Here in suburban Blackburn and across much of Lancashire you can buy a decent 2 bed starter home, a terrace with a back yard / garden area for 50-60K.
2 people working 35 hours on MW is circa £30k joint income and they could acquire a mortgage of up to £75k.
A 60K mortgage over 25 years is £300 per month give or take. That's cheaper than renting.
I think the issue with many young people is they do not prioritise house buying anymore. Technology, holidays, gap years, a car.... all items that are higher profile for the typical 18-30 years old. It isn't that most can't buy, it is that most prioritise material items and lifestyle above saving for a deposit.
