A recent report found that vacant land in Baltimore could be underassessed by as much as $484 mil. The same problem could exist statewide in Maryland.

This on a top of a property tax system that puts Baltimore City's rate as double the rate of all other jurisdictions.

Might a shift to a land value tax address the problem?

My conversation is with Greg Miller, author of the report published for the Center for Land Economics, Vanessa Beck of Baltimore Thrive, and Stephen Janis and Taya Graham, producers of the documentary "Tax Broke".
