Interest rates will fall, and this is due to the aging population. This problem affects all industrialized countries. The older the population, the higher the pressure towards lower interest rates. Therefore, the increase is only temporary. When it will fall again is, of course, still uncertain. Older people consume less and invest more. The historical increase in the past could be attributed to the baby boomers, who caused exactly the opposite.
Even if that is the case, "temporary" can also mean 5 years or longer in this context. That is more than enough to put downward pressure on prices. So far, the issue seems not to have sunk in with most interested parties. In their minds, the old prices and rough calculations for financing still prevail.
