We have a sort of LVT in New Zealand: council rates are ~0.6% of the land+house value where I live in Christchurch.
* Major issue: LVT is related to valuation, but valuation depends on mortgage rates. House valuations are mostly driven by interest repayments, not scarcity. This was demonstrated in Christchurch because there were homes going for say 30% of “value”, even though housing was in short supply due to the 2010 earthquake. A property could not be insured so buyers could not get a mortgage, and without a mortgage properties were going very cheaply. I bought a uninsurable home for ~$200k that would have sold for about $600k if it was insurable. Insurance was unavailable because the floor was out of level by 60mm due to land movement - but the home was fine. I see friends buy a house based on how much they can afford to pay on the mortgage: the housing market value is not related to what houses are worth but mostly to what people can afford. Mostly a zero-sum game where buyers bid against each other for how much they can pay, and the bank wins.
* An LVT is expensive for retirees. An average home in Christchurch is $750000 which has rates (LVT) ~$5000, a single retiree gets about $21k. There is a rebate of up to $665 from the government for low earners (like retirees). Forcing people to move from their home is pretty shitty - I would like to be able to retire in fair comfort without being forced into a shitty retirement home.
* The NZ government introduced a bipartisan law to force allow infill housing without NIMBY constraints in all cities - overriding almost all city district rules. Housing density will go up, a lot. https://bonded.co.nz/news/what-do-the-new-medium-density-hou...
* Locals complain about farming land being wasted for residential subdivision. This is bollox. Land around Christchurch is low value for farming unless you can get irrigation - water is the resource limitation therefore land is not being wasted. I see similar nonsense reasoning supporting an LVT.
* After the 2010 Christchurch earthquake, about 8000 homes were permanently removed (redzoned[1]). Thousands of new sections were created on existing farmland (greenfield sections) but new housing requires infrastructure that takes many years to build[2]. There are between 100k and 200k homes in Christchurch (depending on when and how you count).
* Saying that LVT is only land value and not the house, is crappy misdirection. Land value is related to the value of the surrounding properties, which depends on the developed value of the surrounding properties. This really shows in Christchurch where a home in a good suburb pays far more rates (LVT) than a similar home in a bad suburb. Land gets revalued by the government, but the figures are kind of made-up.
