The 20-30% of demand you’re citing is your own claim that it’s driven by all cash buyers. I’m not seeing any reason why they would possibly disappear. That class of homebuyers may comprise a smaller portion of demand, but only due to demand growth from mortgage wanters, which again implies lower interest rates.
You’re also conflating demand with quantity demanded, so this chain of reasoning is not correct.
> This is bc of interest rates going higher - nobody who has 3-4% fixed rate locked in will sell (until they have to).
And the asked
> Now imagine those 2 dynamics flipped the other way - what happens to prices then?
And I told you if interest rates went lower then priced would rise.
