In the old days, you used to rent a property while you built up capital to put down as a deposit on a property you buy
In the old days people used to leave school at 16 and go to work. They would stay living at home till they had met someone, saved enough to buy a home and only then get married and start their married life in a tiny flat or house. Then work up from there.
In the old days there was a shortage of rental properties as landlords couldn’t remove you once you had started paying rent and with rent control there was no money for the landlord to repair anything if it went wrong,
@Bythemillpond, That was my generation. Single people mainly stayed in the family home, incomes were pooled, and a couple wouldn't get a sniff of a council house without a marriage certificate. We had a council flat in Scotland, gave it up to move to the North of England. We had to privately rent as being on the 'waiting list' took years, so incomers had little chance. The house we rented was pretty run down, outside lav, but so were plenty of others back then. My mother was not impressed when she came for a visit.
Property was cheaper, relatively, but mortgages were hard to get in the 70s, we had to buy a new build. It was the most basic, cheapest, in an area we didn't like. Eventually we scraped enough for a similar property where we wanted to live. No help from family, no RTB, although I had a manager on a big salary who did just that!
We're retired, own our home outright, but we had to move to a smaller one to pay off the mortgage. Small pensions, (£40 a week less than younger state pensioners) few savings, not all Baby Boomers have goldplated retirements. Ill health, self employment, low paid work, redundancy can all negatively impact on pensions.
Younger generations seem more financially savvy, and much more aware of the need for qualifications, settling into careers before starting families. But there are also far more single person and single parent households, more owners of holiday homes, and BTL is a fairly recent concept. The lack of social housing is also an issue for lower income households. I'd like to see some not for profit landlords build mid range housing on a rent to buy basis. A manageable moderate rent, part of which goes towards a deposit to buy after a set period where the occupier has proven ability to pay. That could help those stuck in expensive private lets who could afford a mortgage, but can't save a deposit. And England needs to withdraw the RTB, as Scotland and Wales have done.
