Good! Second homes in any region with low inventory should be taxed...
nxk•37m ago
Yup
ch4s3•32m ago
It seems like a place like Manhattan might benefit from first up-zoning the low slung sections that are currently 4-8 stories.

My point here is that I'd start with trying to build enough housing before spending political capital on marginal things that neither unlock supply nor generate much revenue.

Daishiman•25m ago
In Manhattan the low zones are due to the soil not being good for higher construction. Lower Manhattan and midtown are made of basalt stone that is extremely strong and apt for skyscrapers.
ch4s3•17m ago
Bedrock is only a little lower in the "Midtown Gap", and in any case a lot of those 4 story buildings could be 8-10.
nickv•22m ago
You're right, when I think of a place that has an overabundance of 2 floor single family homes, I think of Manhattan.
ch4s3•16m ago
You'll notice I specifically said 4 to 8 story buildings.
asdff•11m ago
It isn't that which is the issue. It is the fact greenwich village has been at the same height since even before Don Draper's time. You see, the suburban enclaves of long island and upstate and new jersey and the comparatively more built up areas of manhattan do have the exact same issue with regards to housing, and that is there is little room in the zoned capacity to legally add any more housing.

In 1961, NYC adopted a zoning plan that saw zoned capacity reduced by 80%. These sort of changes to zoning happened around the country in the 1960s and 70s in response to red lining being made illegal. If you can't prevent black people from living near you by law, maybe you could instead prevent anyone from living near you and guarantee a supply side crisis such that the wealthiest individuals in the economy are who can afford to be your neighbors, and in 1961 surely they won't be black. You should look up the median income differences between a white nycer and a black nycer today, it is shocking. Median household wealth for whites just within the scope of new york state, not even at city resolution, is nearly 15x higher (1).

Today, 80 years later, we have kept the racist-by-transitive-property laws on the books all over the country. And as such, cities remain highly segregated by both race and class. Civil right era in terms of housing was essentially a failure to achieve any change from this status quo.

ianm218•5m ago
It has a huge amount of areas that are underdeveloped relative to demand. Many areas with height restrictions that block basically all new developments. For example West Village is one of the most in demand zip codes in the entire world caps new builds around 80 feet. East village caps housing @ mid rise so new grads who live there spend half their income on housing.

He is right.

busterarm•31m ago
I strongly doubt that this is going to have the effect that they want it to. It won't raise the taxes that they expect it to. It won't free up inventory. It will halt construction.
bix6•28m ago
It’ll halt construction on luxury second homes? Wonderful!
galleywest200•27m ago
Taxing second homes would halt construction? Plenty of people out there wish to own a first home, myself included.
JuniperMesos•22m ago
How will that tax result in more houses existing?
stavros•9m ago
It will result in fewer second homes existing, therefore more first homes.
busterarm•21m ago
The cost of construction in _New York City_ generally sets a floor as far as who can afford to pay for it.

The per-apartment cost of construction in Manhattan is more than the retail price of my 3500sq ft house in near-rural South Carolina.

Daishiman•24m ago
Those homes are built for money laundering anyway. Good riddance.
WarmWash•9m ago
New York City rent exists at an equilibrium.

The draw for people to move there is so intense, that any draw downs in rent are met with upticks in immigration.

Adding housing stock in NYC is not like adding housing stock in Lawnsdale Ohio. Almost by definition you cannot out build the demand for housing.

a_shovel•6m ago
I don't think the demand for second homes worth over $5 million is a major driver of construction of new units in NYC.

stavros•10m ago
What's the context here? Isn't he doing enough?
jmclnx•30m ago
> an initiative to appease Mayor Zohran Mamdani and liberal voters

Taxing the rich is not a Liberal thing, but the Rich is calling it that because they do not want to pay any taxes at all.

He was elected because people are starting to feel real pain and seeing the ultra rich paying far less taxes then they are. If it was up to me, I would tax all the second homes above 5 million USD and add a Luxury Tax on all valuable Autos too.

busterarm•26m ago
The top 1% of NYC residents contribute 40-48% of all personal income tax collected in NYC. When you extend that to Top 2.5% you cross 51%.

Personal Income Tax accounts for around 31% of collected NYC tax revenue.

"The rich" also pay property tax. NYC's poorer residents generally don't have property to pay tax on. Everyone pays sales tax equally.

So how exactly are the ultra rich paying "less taxes"?

jjav•20m ago
Surely you know this, but the rich are paying less percentage taxes relative to the money they have.
busterarm•18m ago
I'm familiar with the concept of crabs in a bucket, yes. That's why I left New York and abandoned my rent controlled apartment to do so.
lovich•14m ago
Oh shit, I didn’t realize the billionaires who can have multiple homes in Manhattan are crabs in the same bucket as us.

Luckily the law is much more egalatarian and bars the rich and poor alike from sleeping under bridges or stealing bread.

busterarm•13m ago
NYC only has 154 billionaires. The percentage of NYC's second homes owned by NYC billionaires is fractional (59,000 total units).

No, this will disproportionately negatively affect middle-class people and families and fuck them hard.

lovich•8m ago
If you have a second home in manhattan, you are not the middle class _and_ you can afford it.

If the idea of paying taxes affects your poor fragile mind so negatively then there is an easy solution where you can seek said extra home.

No one is being fucked hard by this other than people who are appalled at the thought that they need to contribute to society for the negative externalities they create, like accumulating excess shelter in regions with a dearth of housing capacity.

2OEH8eoCRo0•19m ago
Voters don't feel like it's a fair deal. Telling voters that their concerns aren't real is a losing strategy.
9dev•18m ago
This claim is often repeated but simply misleading. Taxable income is only a tiny fraction of the wealth of ultra rich folks - many even take symbolic wages, because their real compensation happens in stock, which they can use to lend effectively infinite money. There's a great episode of the Ezra Klein Show on this topic too[0].

AdrianB1•6m ago
That does not address the point. You say they should pay even more to address the idea that very few people pay most of the taxes, what is the logic here?
nickv•13m ago
Because wealth is also distributed in a very lumpy way across the city.

154 residents of NYC own 33% of the entire wealth of the city... notice I didn't say 1%, I said top 154. They are not contributing 33% of the tax income to the city.

So yes, the ultra rich pay "less taxes" if you look at how much of the resident wealth they control.

Also, property taxes are significantly lower than appraised value and the richer you get the bigger the disparity. That Ken Griffin’s $238M penthouse pied-a-terre? It's assessed value is $9M. So yea, he's paying like $150k/yr in property taxes.

And finally, it is a known fact that sales tax definitely hits poor people harder (re: "everyone pays sale tax equally"). What you want to look at is what percentage of a person's post taxincome vs sales tax paid, because if you make like $60k/yr you're probably close to 60% of all post tax income paying some form of sales tax (you buy with all the money you make). If you have $2B, your percentage of "tax paid as sales tax" is significantly lower, because you don't typically spend a billion dollars the same way you spend $60k.

giantg2•12m ago
"seeing the ultra rich paying far less taxes then they are."

Is this actually true? I thought looking at the aggregates that the top 10% pay something like 1/3rd of all income/cap gain taxes.

bryanlarsen•9m ago
Top 10% is the upper middle class, not the ultra rich. A successful surgeon making $1M per year is paying well over 40% a year in taxes, while Bezos is paying 1%.
giantg2•3m ago
Do you have the data for that?
dwa3592•2m ago
Last year year Jeff bezos and I both paid taxes for the year of 2024. The percentage he paid on the money he made is far less than I did. I gave higher share of my income to the government than he did. Bezos's true tax rate was less than 1% and mine was around 25%.

i am not in NY, but aren't yearly auto registrations scaled significantly by the value of the auto?

that seems to be true in Arizona, for example.

California next please! If you aren’t in your home 9 months of the year you can stay in a hotel. Thanks!
tlogan•22m ago
I assume this will be challenged in court immediately. Does anyone understand whether it is likely to survive those legal challenges?
zaphod12•19m ago
NYS already has tax breaks for one's primary residence which varies by income and a tax on the sale of homes >$1Mil. Given how entrenched those are, I have trouble imagining a way in which this new tax is incongruous with existing rules.
tekla•16m ago
I dunno why anyone thinks this matters. https://comptroller.nyc.gov/reports/the-pied-a-terre-tax-and...

"We find that, before adjusting for these factors, our choice of tax rates and brackets could raise almost exactly $500 million from a little over 11,200 properties. However, revenues could be reduced to between roughly $340 million and $380 million based on assumptions on exclusions for rented units and behavioral changes following the imposition of the tax."

It's all media feel goodsies but not actually do anything substantive.

free_bip•14m ago
So it'll still raise at least 300 million? Sounds like a great thing to me. I dunno why you think it doesn't matter.
jonfw•12m ago
I think that this has the benefit of both raising a non trivial amount of money as well as reducing housing demand from the wealthy in a supply constrained market
bsimpson•8m ago
Reactionary taxes like this have a tendency to be ill-considered and have unintended side effects.

NY also has a 1% penalty on paying more than $1 million for housing, which was probably enacted to proletariat applause when $1 million was still considered a lot of money. Now it distorts the value of entry level housing in NYC, where you'll have a hard time finding anything more than a studio apartment for $1 million. High closing costs and similar distortions mean people tend to lose money on housing in NYC unless it's held for many years.

$5 million is expensive enough that this probably won't add much housing stock in the short term. Still, politicians never seem to think through the consequences of headline-grabbing tax policies.

braiamp•4m ago
Even in worse case scenario, which this isn't, the affected persons would at most try to cheat the system. This proposal is really narrow to non-primary residences, that are also very valuable. None of which will affect 99.999% of the population.
saulpw•2m ago
Gosh, 1% on $1m, that's almost $10k! I can see that how would discourage homeownership and distort the market.

Actually wait, I can't.

AdrianB1•7m ago
NY should tax anyone with any money until everyone leaves. Then abolish money, like in Star Trek, and live the utopia. I don't think this will happen during my lifetime, but I am not missing it either.
