Could we fix that with a vacancy tax for retail?

There are too many factors that intersect to lead to these outcomes that make it easy to detect any one silver bullet. Valuing a property based on rents seems to be another big issue since it sets up incentives to increase rent and valuations even when the real estate market doesn't support that rent increase.

Value the property tax based on rent, that won't interfere with the real market value.

It's part of the solution. Vacancy has negative externalities so we should tax it.
