In this episode, Patrick McKenzie (patio11) and Lars Doucet, the author of Land is a Big Deal, discuss how cities determine your property's value and collect taxes. They explore how assessment offices juggle political pressures, statistical models, and technological tools while trying to maintain equity across millions of properties. They also cover why assessment offices are separate from tax collectors, how property value protests actually work, and why your neighbor's house might be assessed differently than yours.
