It is interesting though why house prices have gone to being 9 or 16 times the salary instead if 3.
Back in the 90s, for a couple a mortgage was a standard 3x the higher salary plus 1x of the second salary, or 2.75 x both salaries added together. This has totally gone out if the window in 20 years - why???
Growing up, I lived in an average area with lots of 3 bed semis and a few older Victorian properties although the 30s semis made up 90% of the housing. Schoolgtirnds gsd parents with jobs like lorry drivers, cleaners and factory workers. They all owned their own home and the 3 bed semis were considered modest, the Victorian properties more posh.
Nowadays the same 3bed semis are around 275k - 350k (depending on whether they have been extended to 4 beds or not). The average factory worker wages couple could not afford one of these but it was bog standard that they did in the 70s, 89s and 90s.
What the hells happened since that these 3 bed semis, which were built for ordinary average workers, mostly lower wage, are now only afforded by higher earners?
I do think the population explosion has to have played a significant part. But people are so busy getting through day to day this has happened right under our noses.
