Seems like the solution if too many unwanted foreign parties are holding your assets is to depreciate your assets.
For whatever reasons houses are considered appreciating assets, even super old ones.

But this can also be achieved in current property tax regimes by upzoning to allow more density. This will raise the value of the land (because it's now possible to build more density on it), which once reassessed, will also raise the property taxes.
