> The amount homebuyers can afford to pay doesn't change with interest rates.

The amount people can afford to pay doesn't change, but the cost of the house does change.

Assume a 30 year mortgage. If the interest rate is 2%, and I spend 1.5k a month on my mortgage, I can afford a mortgage of 406,000 and own the home at the end. However, if interest rates are 10%, even if I'm still earning 1.5k a month, I can only afford a mortgage of 171000 in order to pay it off by the end. You can double check my figures using this calculator - https://www.bankrate.com/uk/mortgages/mortgage-repayment-cal...

Given that deposits are usually at a minimum 10% of the house price, it's very hard for first-time buyers to gather that amount of money - while people who have purchased before can sell their existing home.

The issue the paper describes is that interest rates have gone down, so house prices have gone up, _and at the same time_ it's harder to get your first mortgage (i.e. you need a larger deposit) - which most new buyers cannot afford.

The error in your logic is assuming the bank is going to want the same % down payment for a 2% and a 10% mortgage.

A down payment is usually a percentage of the value of the house (typically 10-20%). If the house is worth more, the down payment is higher. As I said before "effectively people who have bought before can buy another house, while those who haven't can't". A higher downpayment is yet another barrier. However those who have houses already can use their existing previous equity as a downpayment and therefore can sell their home and buy another.

This underscores the view I was promoting - that interest rates play a large part in the difficulties besetting new buyers.
