(from another article that isn’t paywalled) "A land value tax reduces (or eliminates) the value a structure adds to a property’s tax bill. Instead, it primarily taxes the value of the land. "

Explains in detail that a homeowner who lives in, and maintains or improves their house, won’t be increasing their property taxes in doing so, and someone who owns a dilapidated/condemned building or vacant lot will be paying a more equal share of the overall tax burden.

It’s not a terrible idea tbh… runs a fair chance of increasing the number of tax defaulted properties the city has to contend with, but should definitely reduce the number of properties that people are just sitting on waiting for an economic recovery.
