I’ve been reading/watching a lot on this, the general consensus is that the factors that encourage interest rates to go down are outweighed by the factors to push interest rates up, and will be for some time, so it’s very doubtful we will see sub-3% rates for many years yet.
My main concern with your approach is that your thinking is based solely on the mortgage dropping as rates ease, but the cost of living will not drop alongside. All areas of life, groceries, utilities, insurance etc continue to see unprecedented rises and whilst that trajectory will not continue to be so steep it WILL continue to rise, and honestly unless people start to take their retirements seriously I don’t know how anyone taking on such a lot of extra debt during a time of such a lot of extra payments can also afford to save extra to live on when they retire. It just seems like a house of cards
