> Regular people also commit fraud which can make some differences here.

Yeah, but it's hard for a regular person to under/overreport a property by, say, 200 million USD, and most people do not have the power to negotiate with or bribe municipalities to get different tax treatment like big companies and the rich people owning them do.

> Unpaid property taxes result in forfeiture

Avoided taxes are not unpaid taxes - we're not speaking of people on the run from debt collectors, but people who cheat their way out of having to pay anything.

> So do regular people

What regular people own properties in foreign countries selected for their tax benefits, for investment or recreational uses?

Most regular people own between zero and one property. Granted, they could move, but it takes extra riches to be able to casually straddle multiple borders.

Expats often chose their location based on such factors.

Good luck finding someone who actually pays zero property tax on US land they own. You’re assuming loopholes exist that don’t.

Comparing wealthy taxation is only meaningful based on percentages. There’s definitely people who avoid property taxes by failing to disclose they built a house on undeveloped land thus avoiding 50+% of their tax bill.
