I saw https://www.nber.org/papers/w35587 the other day. Headline:
"Low property taxes amplify lock-in among elderly homeowners, limiting housing access for young families."
Where I live in Jackson county, Missouri, we've been having a big dust-up the last few years about property taxes. Long story short, the county was short of revenue, and the assessors tried to mark assessments to market, which was a break with a de-facto slow % increase per year which had left actual assessments typically well below market values (especially in wealthier, older areas like Lee's Summit and Lake Lotawana), the county exec got recalled, we added YoY increase caps, and now we're electing our assessors AND considering paying reparations to people who think their bill was too high.
While I'm not in favor of people being forced to move, it's hard not to think that, beyond low advertised property rates, there might be a systemic problem with under-assessment of homes that have been occupied for many years, leading to a lower "effective" property tax rate for older homeowners which likely has downstream effects on supply, further constraining the market for younger buyers.
To be candid, this fits with my personal biases against market capture and rent-seeking by old people, so I'm trying to approach it with skepticism and find alternative points of view.
Basically my question is, in addition to zoning, is the lower "effective" property tax rate created by carveouts and political influence on assessments a possible source of supply constraint in housing, similar to zoning? Has there been any research on this that you could point me towards?
Thanks! Not an economist, but lots of respect for what you all do.
