To be honest, I don't like being in debt, and I'm lucky enough not to have a mortgage or any other debt burden. However, it's common knowledge that using the leverage to purchase capital assets in an inflationary environment is not necessarily a bad thing. Monetary 'hyper-inflation' will likely compensate for the demographic-driven real estate bear market you foresee. I.e.: real house prices will decline less or on par with the real value of your debt -> all remains basically equal cereris paribus.

In other words you cannot really print houses and even less arable land. Scarcity scale: Bitcoin>Precious Metals>Art>Real Estate>Equity>Non precious commodities>Consumer Goods>Currencies

What do you mean? You expect rents and prices to dip?
