Yes, but your property tax rate is a much lower recurring rate than the capital gains tax rate. In fact, a tax like that on unrealized gains would probably be a much better way to structure things. You pay 1% a year on unrealized gains until they are realized, at which point you can deduct what you've already paid. I guess this would be annoying to calculate, though.

Good news the unrealized gains are in a form very similar to what you outlined.
