At the same time as their funds deteriorated and the values of their buildings declined, homeowners of bigger rent-regulated buildings noticed their property taxes improve.
In the meantime, the disparity between the assessments on high-end condos and co-ops grew, giving the homeowners of a few of the costliest properties within the metropolis an enormous property tax break.
These two information factors, in a report launched Tuesday by the NYU Furman Middle, highlight how town’s broadly derided property tax system locations an unlimited burden on bigger rental buildings, particularly these with principally lease regulated models, whereas offering big tax breaks to householders, particularly those that occupy the priceless condos and coops.
Whereas the Furman report is the most recent in a lengthy line of research to doc the failings in New York Metropolis’s byzantine guidelines, it comes amid conflicting indicators over whether or not Mayor Zohran Mamdani is dedicated to delivering on his marketing campaign promise to repair the property tax system. The administration has been unwilling to present a deadline for proposing a reform package deal though on June 6 it agreed to barter modifications with advocates below court docket supervision.

“The vital factor to remember is that these disparities will discourage new improvement and undermine preservation,” mentioned Brad Greenberg, Furman’s govt director.
The evaluation by Furman, launched as a part of its annual survey of town’s residential actual property market, exhibits:
- Buildings with three or fewer models, primarily-single household properties, comprise nearly half of the market worth of all residential buildings however pay solely 15% of property taxes. Rental buildings account for 1 / 4 of the market worth, however pay 40% of the levy.
- No metropolis within the nation locations such an enormous burden on rental properties in contrast with householders, the report notes, citing information from the Lincoln Land Institute. New York taxes rental buildings at 5.67 occasions the speed of owner-occupied properties. By comparability, the disparity in Los Angeles is 1.01 and Chicago is at 0.98.
- Taxes are rising for rent-regulated buildings which have seen their funds squeezed. Since 2019, internet working revenue for lease regulated buildings after adjusting for inflation declined by nearly 15%, however their inflation-adjusted property taxes per unit have elevated from a mean of $2,843 per unit to $3,082.
- Co-ops are valued at solely 1 / 4 of their market worth and condos at solely 20%, in accordance with a Furman evaluation of 10,000 gross sales in 2025, ensuing within the lowest taxes when put next with market worth.
The unfairness of the system begins with assessing single-family properties based mostly on market values however rental buildings on revenue and bills. The inequities are exacerbated by caps on will increase in values of single-family properties, which supplies a bonus to householders in areas with rising property costs.
With householders among the many most energetic voters, the Metropolis Council routinely decreased will increase of their property taxes and transferred the burden to residence buildings and different kinds of actual property, all of which pay extra in taxes in comparison with their market worth than householders.
The largest pressure has been positioned on buildings that are nearly completely lease regulated, partially as a result of, in a quirk, town caps how a lot of their elevated bills might be thought of for evaluation functions, the report says.
In the meantime, whereas the legislation requires single-family properties to be assessed utilizing market values, it mandates town to evaluate condos and coops as in the event that they have been rental buildings. With few “comparable” buildings in prime Manhattan areas, these assessments are notably low. In Furman’s evaluation of gross sales information, the largest hole between assessed and market worth got here from the highest 10% of gross sales by worth.
“It’s a fairly vital reality,” mentioned Vicki Been, school director at Furman and the deputy mayor for housing throughout the Invoice de Blasio administration. “The homeowners of the top-valued residences within the metropolis are getting an enormous tax break.”
Each Mayors de Blasio and Eric Adams promised to overtake the property tax system however didn’t develop a proposal to ship to Albany for legislative approval. Since most proposals are designed to maintain the precise quantity taxes collected the identical as now, reforms would doubtless anger householders who would see their taxes improve, though the impression could be phased in.
Mamdani pledged throughout the mayoral marketing campaign and once more in his inaugural deal with to do what his predecessors wouldn’t, partially as a result of he mentioned the system was unfair, but additionally as a result of it might assist landlords of lease regulated buildings cope with his proposed four-year lease freeze.

Now the Administration is sending conflicting indicators about what it intends to do.
At a Could breakfast sponsored by the Residents Funds Fee, metropolis price range director Sharif Soliman would solely say that the administration was nonetheless learning the problem and recommended it was additionally taking a look at taxation of business and utility properties, which might make change much more politically difficult.
However Friday, town agreed to barter reforms with the Tax Fairness Now Coalition, which is pursuing a lawsuit that argues town’s system is unconstitutional as a result of it discriminates in opposition to individuals of coloration.
It isn’t clear what may come of these talks, however the coalition has insisted that town by itself has the facility to make modifications that would cut back inequities.
‘Complete Reform’
Mamdani’s workplace reiterated its plan to reform property taxes in an announcement to The Metropolis Reporter.
“Our administration intends to repair this technique via complete reform. The passage of the pied-a-terre tax demonstrates the mayor’s capacity to work with our companions in Albany to get complicated tax coverage modifications over the end line,” mentioned spokesperson Matt Rauschenbach.
The newly enacted pied-a-terre tax complicates the problem additional, because it requires town each to make use of market values to find out the extra tax on luxurious second properties for the following two years, which suggests it expects the system to be reformed by then.
Within the meantime, the disparities on the way in which town taxes the costliest condos and co-ops will turn out to be even clearer each to those that need reform and to those that don’t.
“You’re mainly telling everybody how a lot their tax would possibly improve should you began valuing coops and conds in accordance with market worth,” mentioned Been. “And that’s going to create a really noisy group wanting to carry on to their present tax break.”
