Oregon has a deferral where the delayed property tax comes from the value of the house when it is sold or I guess when you die. https://grantsforseniors.org/property-tax-relief-for-seniors....
Washington has a similar thing.
"All Washington counties offer senior citizens and disabled households property tax exemptions. Eligibility is based on your age or disability status, home ownership, residency in Washington, and income level. Seniors who are at least age 61, or retired from regular gainful employment by reason of a disability, with an income of $64,000 or less are eligible."
The idea is to help people stay in their houses. This is really really important. And if you can afford it, you should be paying property taxes. I'm lucky I can afford mine, but I highly support this strategy.
In my state I occasionally see people in online discussions saying they can't afford their property taxes - I think a lot of people aren't aware of these programs, people are amazed when I post a few pointers and tell them about it.
Quite the opposite.
Telling people that the solution is to sell their home to an insurance company as a solution is most certainly a corporate land grab.
You seem to be arguing about people/corporations that own multiple homes or even entire portfolios of property. These are not the same argument.
If their asset is gaining in price so much that the tax burden is getting high, then tax deferement until a liquidity event both keeps them in their home, but also keeps them honest about how much they are taking away from the rest of society by taking that piece of land.
The premise does not warrant this conclusion.
