If interest rates plummet and people start purchasing houses that they can only afford due to cheap loans, I would expect home prices to… rise. As they did before.
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.
Operative word being "If"...
What if rates go up?
Look at it from the perspective of the fed:
- Home prices up (or neutral)? Check...
- Stock market at all time highs? Check...
- Strong labor market + low unemployment? Check...
- High inflation? Check...
^^ The combination of the above make the case for rate increases, not cuts. [1]
