In some places, yes. In other places they don't (or are incredibly small).

More generally, if you're going to tax wealth property is the place to start.

Like I said, that isn't what is bandied about as a wealth tax. Elizabeth Warren proposes a 2% annual tax for net worth over $50 million and 6% for over $1 billion. It is literally taking a percentage of what they own every year. Don't forget, they would still pay taxes when selling assets.
