The ratios are still very much the same, you can borrow more at a lower rate which works out at roughly the same and you still had to have a deposit.
I looked a the figures from my flat, bought in 1998, compared it to buying now. Assuming 5% deposit and 9% interest rate then, 20% deposit and 2.5% interest rate now.
(Those are actual typical variable mortgage APRs for the time published by Bank of England.)
Then I would have needed a 10K deposit and annual mortgage payments would have been 19K.
Adjusted for general inflation, in today's money that would be a deposit of 14K and annual mortgage payments of 27K.
Now I would need a 130K deposit and annual mortgage payment would be 28K.
So initially it looks like you are right with regard to monthly payments, and people are "only" worse off now because they'd have to find a 130K deposit rather than just 14K.
However my actual mortgage payments in 1998 were equivalent of 14K in today's money, I think because of a five-year introductory deal, plus it being an interest-only mortgage. I doubt you could get a similar reduction on today's mortgage.
