This also closes some loopholes/arbitrages around declaration of primary residence for purposes of NYC income tax. There are C-suite execs who declare residence in CT/NJ while spending < 180 nights/year in NYC in their huge apartment, allowing them to avoid NYC income tax.

Anyway, NYC real estate taxes are a mess and in some cases regressive.

For example, taxes are based on values set by the city which for the ultra high end, the are understated by an ORDER OF MAGNITUDE..

See: > Griffin purchased his 24,000-square-foot penthouse at 220 Central Park South in 2019 for $238 million. ..t he city values the apartment at just $15.5 million .. property tax bill for the 2026-2027 tax year is $858,332

.. Griffin’s property tax bill would more than double to $1.87 million .. in the 2028-2029 tax year, it would increase to just under $4 million

I don't feel terribly about someone paying $4M on property probably worth close to $400M at the moment. Normal high income NYers already pay $10-20k/year on properties worth $1.5M by comparison.

Another regressive aspect there was a proposal to change was a purchase tax for cash purchases. Currently one of the closing costs in NYC/NYS is a mortgage recording tax of nearly 2% of mortgage amount. This means if you are rich enough to buy in cash, you can avoid this tax. And if you are a rich cash buyer you are probably buying a higher end property so.. doubly regressive in a sense.
