Sorry but I completely disagree if it's your first home and not a speculative investiment. In an inflationary system, it's much better to have a fixed-rate mortgage backed by fiat currency from a bank than to be at the mercy of your landlord, who can adjust the rent price with inflation.

And even as an investment, undervalued Real Estate (expecially agricultural land) is oftentimes a better asset class than bond, bills and currency on bank accounts.
Ok, course....Bitcoin and Gold are in another league..
When RE markets enter a secular decline You'll see what happens to Your 'fixed-rate' mortgaged
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.

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