The quarter before the line was drawn

Manhattan closed the second quarter at a record. The median sale price reached $1.25 million, up roughly 4.2 percent year over year, according to Douglas Elliman and Miller Samuel. Closed sales fell. Inventory ran about 15 percent below the prior year, and luxury listings dropped to 796 — the thinnest count in twenty-two years of tracking.

Read carefully, that is not a demand story. The median rose because the transaction mix shifted upward against very little supply. Fewer people bought, and the ones who did bought higher.

Then, on the first of July, the terms changed for a specific subset of them.

What the statute does

Article 30-C of the New York Tax Law took effect on 1 July. In its first phase, running through June 2028, it applies an annual surcharge of between 4 and 6.5 percent to condominiums and cooperative apartments assessed at $1 million or more that are not the owner’s primary residence. One-to-three-family houses are captured at $5 million and above. A second phase, from July 2028 through 2031, narrows the levy to second homes valued above $5 million.

The distinction between assessed and market value is doing real work here. Because New York assesses class-two residential property well below what it trades for, the headline range of 4 to 6.5 percent lands closer to 1.3 percent of market value in practice. The Comptroller’s office has estimated the measure will raise roughly $500 million annually for the city.

Primary residences are exempt. That is the whole of it, and it matters more than the rate.

For the first time in recent memory, New York has attached a recurring cost to a buyer’s intent rather than to the price of the asset. Two identical apartments on the same line of the same building now carry different economics depending on who sleeps in them.

Four weeks of evidence

The early data is thin and should be treated that way. But the shape is legible.

In the first full week after the tax took effect, Olshan Realty counted 29 contracts signed at $4 million and above, totalling $182 million — up from 15 in the holiday week before. Broad luxury demand did not collapse.

The trophy tier is where the hesitation shows. Between 6 and 12 July, exactly one Manhattan property above $10 million went into contract, against a customary three to five. It was the weakest week for that segment since late December. Of the 29 contracts signed that week, twenty were for apartments asking under $6 million.

By the third week of July, 18 contracts at $4 million and above matched the ten-year average for the period, and two deals cleared $20 million.

A pause at the very top, absorbed within a month, with activity concentrating in the band below it. Jonathan Miller has cautioned against reading much into any single week, and he is right to. But the direction is consistent with what the statute was built to do.

Brooklyn, where the exemption is universal

Across the river the tax is nearly invisible, because almost everyone buying is exempt from it.

Brooklyn posted its own records in the second quarter. Median and average price both rose 11 percent year over year to all-time highs, according to Corcoran. Average price per square foot reached $1,185. Resale condominium median price climbed 15 percent to $1.15 million.

Supply grew — active listings rose 8 percent to 2,003, the highest second-quarter figure since 2022 — but not where it counts. Inventory above $2 million fell 17 percent. Inventory above $1 million declined 5 percent, in a segment responsible for more than forty percent of the borough’s sales.

Property moved quickly. Days on market fell to 72, the fastest second quarter in a decade. In the $750,000 to $1 million band, average marketing time dropped 27 percent, to 49 days.

A borough of owner-occupiers, buying into rising prices and thinning supply at exactly the level where they transact.

What this asks of a buyer

Two things follow, and neither is about the rate.

The first is that documentation now carries weight it did not carry in June. Primary-residence status is the exemption, and exemptions are administered through paperwork. Industry groups have already warned the tax will be difficult to apply cleanly, and the bracket mechanics remain subject to Department of Finance regulation. Any buyer whose situation is not perfectly simple — trusts, corporate entities, families splitting time between two states — should have an answer from tax counsel before signing rather than after.

The second is that the top of the market is now negotiating against a carrying cost that did not exist eight weeks ago. A seller asking $12 million is addressing a smaller pool of buyers, several of whom have quietly repriced the asset by the annual surcharge they will pay to hold it. That is leverage, and for once it sits on the buyer’s side of the table.

Which is the ordinary work of representation: knowing which side of a change in the law you are standing on, and pressing it. At BRN that work is done by the partners themselves — and because we take one side of a transaction and never both, half of the commission we receive is returned to the buyer at closing.
