House hacking math doesn't add up

[Roy Gottesdiener]

On the podcast David keeps saying that house hacking is the easiest way to build wealth through real estate, advising to add one property each year paying 5% down.

I'm theory it sounds great but in reality assuming you buy a property in the 500k range, there's no way you'll be able to make it cash flow which makes it hard if not impossible to actually scale and do this every year or two.

What are your thoughts? Am I missing something?
