In the third quarter of 2026, the typical Upper East Side resale condo closed at 94.4% of its asking price and spent a median 94 days on the market. The typical resale co-op closed at 97.4% of ask after 83 days. That's a gap of three percentage points at the negotiating table. On a condo at the quarter's $1,875,000 resale median, a 5.6% discount works out to about $105,000. On a co-op at the $1,100,000 median, the 2.6% discount comes to about $28,600.
Condo medians are up. New-development inventory on the Upper East Side is the tightest in Manhattan. Brokers say a new tax is pushing buyers toward condos. All of that is true. Even so, the resale condo seller is the one who ends up giving ground. The shortage on the Upper East Side is a shortage of new sponsor units, and it gives resale condo sellers very little leverage.
The Gap, Side by Side
Two Q3 2026 datasets measure the Upper East Side differently, and they still agree on direction. One is an UrbanDigs compilation of public records and REBNY Listing Service data for July 1 through September 30, 2026, limited to resales in buildings more than five years old. The other is a brokerage closed-sales table covering all Upper East Side condo and co-op closings for the quarter.
| Q3 2026, Upper East Side | Resale co-ops | Resale condos |
|---|---|---|
| Median sale price, UrbanDigs resale data | $1,100,000, up 2.3% YoY | $1,875,000, up 11.6% YoY |
| Median price per sq ft, UrbanDigs | $1,027, up 5.1% | $1,505, up 5.5% |
| Median days on market, UrbanDigs | 83, down 5.6% | 94, up 17.5% |
| Sale-to-list, UrbanDigs | 97.4% | 94.4% |
| Average discount, all closings | 5% | 7% |
Co-ops sold faster than a year earlier, and condos sold slower. Co-op sale-to-list improved by 1.5 points year over year. Condo sale-to-list slipped by 0.3 points. Both sources show condo sellers conceding more, and the gap is widening on time to sell.
Much of the Condo Price Jump Comes From Bigger Units
Look at the medians first. In the UrbanDigs resale data, the condo median rose 11.6% in Q3 2026, but condo price per square foot rose only 5.5%. If the median sale is climbing twice as fast as the price per foot, a big part of the climb has to come from larger apartments trading hands.
The all-closings table spells this out. Among Upper East Side condos closed in Q3 2026, average size rose 6.2% to 1,582 square feet, and average price per square foot rose 3.9% to $1,693. Even so, the condo median slipped 0.7% to $1,985,000. Co-ops moved the other way. Average co-op size fell 10.1% to 1,274 square feet and the average co-op price fell 8.1%, while average co-op price per square foot rose 6.6% to $1,153.
The two datasets have different scopes, and one says the condo median rose 11.6% while the other says it dipped 0.7%. They shouldn't be blended into a single figure. On a per-foot basis, the two moved almost in step in the UrbanDigs resale data, up 5.1% for co-ops and 5.5% for condos, and in the all-closings averages co-ops gained more, 6.6% against 3.9%. Co-ops did it while selling closer to ask. A condo seller who reads a double-digit median gain as a raise for their own apartment is pricing off a shift in which units sold.
The Shortage Is in New Development
The scarcity story is real. According to Marketproof data reported by The Real Deal, unsold new-development units on the Upper East Side fell 76% from 2021 to 112 units. The neighborhood has less than eight months of sponsor supply, compared with 23 months across Manhattan, and holds just 2.9% of the borough's unsold sponsor units.
That shortage is what makes each new launch a marker for the whole neighborhood. Here is what's selling or lined up this fall:
- 175 East 82nd Street, Douglaston Development's 73-unit tower, launched sales in September with one- to six-bedroom condos and four penthouses. Prices run from $3 million to $40 million, and construction is expected to finish next fall. Mansion Global gave the launch date as Sept. 22.
- Elodie, 439 East 77th Street, a converted carriage house, is selling 16 residences from $1.25 million to $8.5 million. Its two townhouses start at $5.995 million, and move-ins are targeted for Dec. 1, 2026, 6sqft reported.
- Maison171 by Elie Saab, 171 East 86th Street, is slated as a fall launch with 24 condos priced from $2.5 million to $18 million.
- 260 East 72nd Street, a 60-unit project, is preparing to launch with anticipated asking prices of $3.6 million to $30 million.
- 84th Street and Third Avenue, where Legion Investment Group and SMA Equities announced a 300,000-square-foot residential project in September with few details released.
Those projects follow Miki Naftali's earlier Upper East Side buildings, including the Benson, the Bellemont, and 200 East 83rd Street. The Real Deal notes that penthouses at 200 East 83rd on Third Avenue have traded for nearly $40 million, which pushed the luxury market's edge toward the East River. A marketing executive quoted in the same piece credits the new buildings with "drawing people farther east, with amenities and views you're not going to find on Park or Fifth."
How the New Launches Raise the Bar for Resale Condos
None of the sources we reviewed offers an analyst's explanation for why Upper East Side resale condos discount more than co-ops. What follows is our reading of the numbers.
A buyer shopping for a condo on the Upper East Side this fall is likely touring a fifteen-year-old two-bedroom on the same weekend they see the sales gallery for a new tower with amenities and river views. New launches set the reference point for what a condo here can be, and a resale unit gets measured against that standard. Its owner, meanwhile, has watched headline medians climb and the new-development pipeline thin out, and often lists with both in mind. When the asking price follows the new launches and the buyer's comparison follows the finishes, the difference gets settled in the final negotiation. That fits the 94-day median and the 94.4% sale-to-list ratio.
Co-ops are priced in a narrower market. The Upper East Side is the co-op heartland: in Q3 2026 it accounted for 27.4% of Manhattan's co-op closings, compared with 12.2% of condo closings. Hardly any new co-ops are being built for buyers to compare against, so a resale co-op mostly competes with other resale co-ops. That makes asking prices easier to set and harder to stretch.
The pied-Ã -terre tax adds another factor. Brick Underground reported on Oct. 2 that brokers see the new tax "fueling a shift toward condos." One agent argued that co-op boards are becoming more restrictive toward non-primary residents, and that buyers worry a co-op could limit their future resale pool. In principle, that should help condo sellers. Through Q3 2026 on the Upper East Side, it didn't show up in resale condo sale-to-list ratios. Any extra demand the tax sends toward condos also lands on the new launches listed above.
What September Suggests About the Months Ahead
The quarter ended on a softer note. Mortgage rates have climbed back above 7%. Brown Harris Stevens CEO Bess Freedman, quoted by Brick Underground, said low inventory and broader economic concerns "led to a sharp reduction in signed contracts in September, which could mean a softer fourth quarter for closings." One brokerage's neighborhood index shows Upper East Side pending sales down 20.4% over the course of Q3 2026.
At the same time, total Upper East Side listings fell 7.9% year over year to 1,232 in Q3 2026. So the neighborhood is heading into the fourth quarter with fewer listings and fewer signed contracts. Many Manhattan buyers pay all cash and are less exposed to rates, as The Real Deal noted the same week. Financed buyers comparing a resale condo with a new launch are the most rate-sensitive group in the market, and they're the buyers resale condo sellers most need.
Reading Your Offer Range Through This Gap
For a buyer comparing the Upper East Side with other neighborhoods, the Q3 data points to three practical takeaways:
- Use price per square foot, not the median. A condo median that climbs on bigger units says little about the apartment in front of you. In Q3 2026, resale condos traded at a median $1,505 per square foot and resale co-ops at $1,027.
- Check days on market against the 94-day condo median. A resale condo that has sat past that mark is at the point where, in this quarter's data, sellers were conceding more.
- Expect less room on co-ops. At 97.4% of ask and an 83-day median, Upper East Side co-ops gave up little in Q3 2026. That's especially true at the size breaks, where resale two-bedroom co-ops had a median of $1,500,000 against $1,950,000 for resale two-bedroom condos.

A Few Direct Questions
Does a 7% average condo discount mean I can offer 7% under ask? No. An average discount describes where closed deals landed across the whole quarter, including units that were overpriced at listing. Each building's recent sales and the apartment's own time on market say more about a specific offer.
Will the new launches keep pressure on resale condos? Marketproof data cited by The Real Deal shows roughly 240 more new-development units heading to the neighborhood, with eight projects filed since May 2025. More launches mean more new product for buyers to compare against resale condos.
Why don't the two Q3 reports agree on the condo median? One covers resales in buildings more than five years old. The other covers all closings. Each is internally consistent, and both show condos discounting more than co-ops.
The resale condo sellers who close near ask on the Upper East Side right now are the ones who price against the last comparable resale, not against the newest launch.
