The people I know who did inherit a share of their parents house didn’t do so until their kids were at or beyond Uni stage.
I am at the ‘maturer’ end of MN users and have had a worse standard of living than my parents and found it very hard during the childcare years. But then my parents had much lower expectations. Wrt holidays, new kitchens, new bathrooms, they didn’t even have central heating til I was 7. Our cars (the family only had one) were smaller and far more basic.
The NHS treatment on off was more basic with expensive procedures now developed not available.
And then the country was wealthier on N Sea oil and owned our industries.
But housing costs were far more affordable. That’s the big thing.
I live in London so find it normal not to have a house with a drive or a big garden, and always lived in flats or a terrace, except for one semi in a (perfectly normal) family area that many MNers make it clear they would not consider. I have had a good life, my kids had an excellent childhood even on a shoestring.
I do feel for young families struggling with housing costs but in the end most people get through.
It gets easier as the childcare costs reduce and salary (hopefully) increases with promotion or being able to work extra hours etc.
