It is true that in the early 70's an average new or newish 2-3 bed house could be purchased outside London and the SE by a young married couple if the man (lenders usually assumed young women would be stopping work before long) earned the average industrial wage or above in secure employment and the woman had a permanent job. They would multiply his wage by three and add on an extra 25% for her contribution to work out borrowing capacity.It was also expected that they would have saved over a year or two during a formal engagement to put down a deposit.
Because today you need to multiply the average wage/salary by at least five instead of three to be able to afford the same standard of accommodation (over four decades, housing has become a scarce resource because not nearly enough ordinary homes have been built for rent or purchase); and because more people, in spite of better qualifications, are in insecure employment or in jobs that have not kept pace with inflation; it is harder for young people to get on the housing ladder.In spite of lower interest rates!
However, as a Gransnetter with a single son in his thirties who works in the health service and is only now beginning to think about moving out of a shared rented house to buy his own flat, I recognise that times and attitudes have changed.My son has not, in the past ten years, gone without holidays abroad, new clothes, or meals out in restaurants in order to save every penny towards his own place like we did.This I personally find irritating behaviour - a bit like the grasshopper in the Aesop's fable! BUT is this in part because he (like many others the same age) has not wanted to put off living his life as fully as possible outside work for years if it is going to take many years anyway to buy his own home?
Re living in a cheaper area - great if you can do it. But not so great for a younger person if no jobs there.
And yes, many of us would like to downsize, but find smaller single storey properties suitable for older age and disability also a scarce - and so in some areas very expensive - resource. Not everyone over 60
