In my cases as an MS2, my monthly mortgage repayment was just over £600 and my 4 weekly income just under £900.
The thing is that whilst mortgage interest rates are a lot smaller now, that doesn't always mean that they are more affordable.
In 1982 when mortgage rates were 10% the average pay was £6,600 and the average home was £24,000. To make the maths easier we'll assume £0 tax but also £0 deposit.
That would mean that the interest payment for the year would average at £200 a month from £550 pay.
Land Registry suggests that average house prices are £270,000 (others say £300,000, but we'll go with the lower value) whilst average pay is £39,000. Assuming the same £0 tax and deposit, at 5.5% interest is £1,240 from £3,250 of pay
That's not easy to compare so if we factor to £200 from £1,240 for the interest payments that's pay of £525 so around £25 (5%) less pay (1982 prices) to cover the interest payments and yet the rate of interest is noticeable lower now than then (10% then vs 5.5%).
Only that's not the only difference, AI suggests that in 1982 for a house in the West Midlands for the average house price it would be a 3 bed semi-detached house whilst now the average would likely get you a 2 bed terraced house.
Also a 10% deposit of a home would be £2,400 (36.36% of average pay) in 1982 vs £27,000 (71.05% of average pay) for 10% now but still £13,500 (35.52% of average pay) making it harder to save up the 10% deposit and just as hard to save for a 5% deposit (but then higher monthly payments) in the first place.
As such, whilst interest rates were high and lower deposits are an option now, due to other factors it's still likely harder now than it was and it's likely that the size of home is also likely to be smaller.
