Assuming by 'more suitable' you mean a house that is more expensive than your current home then trashed house prices is probably a good thing (for you). The tidal wave of mortgage cost won't be a high because you will need a smaller mortgage for your new house as it should have fallen in price by more than the value of your current home.the issue is if it creates a situation where we can't move to something more suitable in 2025 or even worse just trashes house prices etc then it will have gone too far and I do worry that's happening.
