Rental property billionaire says buying a home (with a mortgage) is "fancy bullshit" and you should rent instead

In a very specific scenario, with a very large amount of running the numbers, as a high income person with low personal expenses and a very good investment advisor, I could see how in certain situations/locations where mortgage rates are much higher than rental rates, that you get better fiscal results investing than paying that mortgage. That was a very rare situation 7 years ago, even more rare now. Where I lived ten years ago, I could not possibly afford the mortgage but I could the rent. These days there the situation has reversed and they're both sky high regardless.
