The Kenyon House at 842 Carroll Street has been on and off the market for nearly two years. Built in 1887 for George and Isabelle Kenyon and designed by C.P.H. Gilbert, the 32-foot-wide Romanesque Revival mansion has 12 bedrooms, roughly 8,200 square feet of interior space, and another 1,200 square feet of terraces and garden. It asked close to $15 million in late 2024, dropped to $14.75 million in early 2025, fell again to $12.789 million by summer 2025, and relisted this past May at $16 million. That is not the pattern of a home caught in a bidding war. It is the pattern of a home that keeps testing a ceiling nobody has confirmed exists.
And yet on August 4, Redfin named Park Slope's 11215 zip code the hottest luxury neighborhood in the entire country for 2026, ahead of every other high-end zip in the hundred largest U.S. metro areas. If you are shopping this market, or watching it from a distance while you decide whether to make a move, that headline and the Kenyon House's stalled price history describe two different neighborhoods. Only one of them is the whole story.
What "Hottest" Actually Measures
Redfin's ranking is not a value index. It is built from year-over-year growth in listing views on Redfin.com combined with the company's Compete Score, a 0-to-100 measure of how hard it is to win a specific home based on days on market, the share of listings that sell above asking, and the sale-to-list price ratio. The data window was January and February of 2026 compared against the same two months in 2025. A neighborhood tops this list because demand is outrunning supply, not because the neighborhood is affordable, undervalued, or friendly to a patient buyer. Park Slope's luxury tier posted a median sale price of $1.77 million in that window, up 10.6 percent year over year, while listing views climbed 34.4 percent. That is a demand signal. It says nothing about how many homes were actually available to absorb it.
The Math That Doesn't Add Up
Here is the part the press release didn't emphasize: home sales in Park Slope fell 17.9 percent year over year during that same stretch. Prices went up while the number of transactions went down, and that pattern holds up across every recent data cut on the neighborhood, not just Redfin's two-month snapshot.
In the second quarter of 2026, PropertyShark recorded a median sale price of $1.8 million across Park Slope, up 21.3 percent year over year, alongside just 99 closed deals, a 16.8 percent drop from the same quarter a year earlier. Over the three months ending in May 2026, Redfin's own broader neighborhood data showed a median sale price of $1.9 million, up 12.8 percent, with the average home taking 47 days to sell compared with 31 days the year before, and only 78 homes sold that month versus 89 the year before. Even the Park Slope Historic District, arguably the most sought-after slice of the neighborhood, followed the same shape over the three months ending in March 2026: median price per square foot up 12 percent to $1.57 thousand, but only 34 homes sold compared with 48 the prior year, and days on market stretching from 34 to 49.
Four different measurement windows, four different data sources, one consistent story: this is not a flood of new buyers overwhelming a normal supply of listings. It is a shrinking pool of sellers commanding higher prices from the buyers who show up anyway.
"The high-end neighborhoods on this list are hot because there's not enough supply to meet the high demand," Redfin Senior Economist Asad Khan said of the 2026 ranking.
That framing matters for anyone deciding when to act. A market defined by scarcity behaves differently than one defined by a rush. There is no wave of inventory coming to relieve the pressure. The 2026 numbers suggest the opposite: current owners in Park Slope are increasingly choosing not to sell, and the ones who do are getting paid for that scarcity.
Where the Heat Concentrates, and Where It Doesn't
The Redfin ranking and the price data behind it describe the neighborhood's mid-to-upper tier best: renovated co-ops, brownstone conversions, and condos in the roughly $1 million to $2.5 million range where competition for well-priced listings has been intense. New construction along Fourth Avenue, where glass-and-steel towers have added most of the neighborhood's condo inventory over the past decade, runs $900 to $1,300 per square foot and behaves as its own separate product category, competing more with new-build Brooklyn condos elsewhere than with the brownstone stock a few blocks east.
The very top of the market tells a noticeably different story. The week of July 13 through 19, Compass reported 18 contracts signed on Brooklyn properties asking $2 million or more, a total of $58 million in volume, down sharply from $137 million the week before. Homes entering contract that week carried a median asking price of $3.5 million, an average price per square foot of $1,474, and an average of 191 days on the market before a deal closed. That is not a market moving in weeks. The priciest contract that week was a Park Slope townhouse at 683 10th Street asking $5.8 million, described in its own listing as having "potential for thoughtful updates" rather than being turnkey.
A few specific transactions from the same summer illustrate the split clearly:
- 611 2nd Street, a landmarked Park Slope townhouse gut-renovated by Adam Khedouri after he bought it for $5.5 million in 2022, went into contract at an asking price of $12 million, the highest of any Brooklyn contract that week.
- 524 11th Street, purchased by an entity tied to Omri Bar-Mashiah's Minerva Development for $2.4 million in 2025, asked $6 million once renovated.
- 683 10th Street, described above, needed work and still commanded a $5.8 million ask, showing that even unrenovated inventory in this tier draws serious offers.
- The Kenyon House at 842 Carroll Street, the trophy property with no active renovation story and a price history that has moved in both directions for two years, remains the clearest exception to the "hottest neighborhood" headline.
The pattern across these deals is that value creation at the top of the Park Slope market comes overwhelmingly from renovation, not from simply owning a landmarked address. Buyers who purchase distressed or dated townhouses and complete the work are the ones seeing outsized returns. Buyers hoping an already-finished trophy home will sell itself, the way the ranking implies, are running into the same stalled timelines the Kenyon House has faced.
What This Means If You're Actually Bidding
If your search is in the co-op and condo range that most of the ranking describes, plan for the market the data supports: competitive, fast-moving, and unlikely to soften while inventory stays this tight. Financing should be lined up before you tour, not after you find something, and offers on well-priced listings need to reflect that days on market in this segment have compressed even as the broader neighborhood's overall days on market has lengthened.
If you're shopping above $5 million, treat the ranking as background noise rather than a forecast. The data from Compass and the Real Deal's weekly contract reports both point to a slower, more negotiable market at that level, one where condition and renovation story matter more than the address alone. A property that needs work is not automatically a liability in this tier. It may be the more realistic path to the kind of value that the mid-tier market has already priced away.
Either way, the number that should guide your timing isn't the ranking itself. It's the sales count. A neighborhood posting higher prices on fewer transactions is a neighborhood where the sellers who remain have leverage, and where buyers need a clearer read on which micro-tier they're actually competing in before they write an offer.
Frequently Asked Questions
Does Redfin's ranking mean Park Slope home prices are inflated right now? The ranking reflects demand pressure and competition, measured through listing views and the Compete Score, not a judgment about whether current prices are sustainable. Price data through the second quarter of 2026 shows genuine, broad-based appreciation across multiple independent sources, which suggests the pressure is real rather than a short-term spike.
If sales volume is falling, why is the market described as hot? Because Redfin's methodology measures how hard it is to win a specific home, not how many homes are trading. Falling sales counts alongside rising prices typically point to a shrinking supply of sellers rather than a surge of new buyers, which is exactly what the 2026 data shows.
Does this ranking apply evenly across all of Park Slope? No. The data underlying the ranking best describes competition in the co-op, condo, and renovated brownstone range roughly between $1 million and $2.5 million. New construction on Fourth Avenue and townhouses above $5 million each follow their own distinct patterns, with the highest tier currently showing longer marketing times and more room for negotiation.
Reading a national ranking correctly means checking it against the transaction data underneath it, and that is the kind of read the Schier Cloonan Team provides for every Manhattan and Brooklyn search we take on.
