Negative interest rates violate the laws of physics.
Interest is the time value of money - what people are prepared to pay to have money now (ie to buy a house) rather than later from saving up.
Given that time can only move forwards, the time value of money must always be positive number. Negative interest rates are a fantasy created by a failing system of fiat currencies being printed wildly.
Real interest rates are reflected by the sort of interest you can get on BTC (ie 6-8.5% or more) from crypto.com, blockfi, Nexo and in the DeFi space.
I'm not sure what will happen to long term mortgage loans when the fiat currency they are denominated in and the financial infrastructure that issued them collapses.
But don't expect to be able to refinance any loan at these fairyland interest rates in a few years.
Interesting you mentioned refinance, yes that would be an issue .... Have to say the rich will stay rich or get rich, the poor will stay poor :(
