Manhattan Rent September 2026: $5,395 Record, Slower Market

Corcoran's September 2026 NYC rental market report, published October 8, covers market-rate leasing in Manhattan and Brooklyn. These are the figures a buyer should carry into any underwriting conversation this month.

September 2026 measure	Manhattan	Brooklyn
Median rent	$5,395 (record)	$4,300
Change vs. August	+2%	-2% (August record: $4,368)
Change vs. September 2025	+9%	+5%
New leases signed	3,841 (-19% MoM, -5% YoY)	1,407 (+3% MoM, +10% YoY)
Active listings	5,015 (-16% YoY, lowest September since 2019)	3,428 (-25% YoY, lowest September since 2022)
Average days on market	48 (+26% MoM, +12% YoY)	53 (+13% MoM, +33% YoY)
Vacancy rate	1.54% (1.51% in August)	Not reported

Two Manhattan details sit underneath the median. The average two-bedroom reached nearly $8,500 per month, an all-time high, and two- and three-bedrooms posted double-digit annual gains. One-bedrooms rose 6% year over year to an average of $5,436, which is $50 below their July peak.

Gary Malin, Corcoran's chief operating officer, put the cause plainly: "Manhattan's rental market remains defined by a lack of available apartments." September's 5,015 active listings is the thinnest September supply since 2019, down 16% from a year ago. The vacancy rate, at 1.54%, barely moved from August's 1.51%.

That is the whole story of the 9%. Rents did not climb because more tenants showed up; leasing volume was 5% lower than last September and 19% lower than August. Rents climbed because fewer apartments were available, and the ones that came to market were weighted toward larger units with double-digit gains.

The 9% also hides a mix effect that matters for small buildings. Most walk-up and small elevator buildings in Manhattan are heavy on studios and one-bedrooms, and the one-bedroom average rose 6%, not 9%, and has already slipped from its July high. If your rent roll looks like that, the like-for-like growth you actually captured this year is closer to the one-bedroom figure than the borough median.

Then there is the time cost. Apartments took 48 days to lease in September, up 26% from August, and Corcoran notes non-doorman listings took about 10 more days than they did a year earlier. At the median rent, 48 days of downtime is about $8,500 in lost rent per turnover, before the broker fee that the FARE Act has put on the owner's side of the ledger since June 11, 2025.

The record Manhattan rent in September 2026 is a scarcity price, not a demand price. Leases fell 19% in a month and days on market rose 26% while the median hit $5,395. An investor who underwrites 9% annual rent growth off that number is pricing the shortage as if it were momentum, and the shortage is the only thing holding the number up.

Brooklyn tells the same story one step ahead. The borough's median rent of $4,300 is 2% below August's record of $4,368, and the average of $4,946 sits about 3% below its June peak of $5,098. Three-bedrooms are the only unit type below last year's level, down 1% to $6,885.

The demand side in Brooklyn is healthier than Manhattan's. Leases rose 10% year over year to 1,407, the strongest September since 2020, with two-bedroom signings up 21%. Studio leases hit 248, a record for any September.

But supply is even tighter than across the river: 3,428 active listings, down 25% from a year ago, and 53 days on market, up 33% annually. Brooklyn renters are signing more leases and taking longer to decide at the same time. That combination reads like a market where asking prices have run slightly ahead of what tenants will pay, and the August median record is being tested.

While market-rate rents set records, the other half of the city's rental stock entered a freeze. The Rent Guidelines Board's adopted 2026-27 guidelines (Apartment and Loft Order #58) set 0% on one- and two-year stabilized renewals commencing October 1, 2026 through September 30, 2027. Our owner's guide to the rent freeze walks through the lease mechanics.

The cost side kept moving. The Board's 2026 Price Index of Operating Costs measured building operating costs up 5.3% from April 2025 to March 2026, with insurance up 10.5% and fuel up 11.0%. Its 2026 Income & Expense Study found 9.2% of buildings with stabilized units already running negative net operating income.

Market-rate units carry their own ceiling. Under Good Cause Eviction, a renewal increase above 8.38% on a covered apartment is presumed unreasonable for 2026-27, a figure set by the DHCR Good Cause notice off a 3.38% regional CPI change. Buildings with a certificate of occupancy on or after January 1, 2009, owners of 10 or fewer units statewide, and units renting above 245% of fair market rent are exempt; we laid out the investor math on Good Cause last month.

Revenue regime	2026-27 renewal ceiling	Share of the story
Rent-stabilized units	0% (Order #58)	Costs up 5.3%, revenue flat
Covered market-rate units	8.38% presumption (Good Cause)	Below the 9% median gain
Exempt market-rate units	None	Where the record rents actually live

So the 9% headline applies in full only to the third row. A building with a mixed rent roll earned something between 0% and 9% this year, and the spreadsheet has to say which rows got which number.

Capital is already pricing this split. Ariel Property Advisors' H1 2026 report counted $4.95 billion in NYC multifamily sales in the first half, up 21%, with 65% of the dollars going to free-market buildings. We covered why the two markets have stopped trading as one asset class, and September's data sharpens that view rather than changing it.

The practical rules for a deal you are pricing this quarter:

• Underwrite in-place rent, not the median. The $5,395 figure is a citywide market-rate median for September leases. Your building's rents are what the leases say.
• Mark to market by unit type. Use the one-bedroom and studio readings for small-building stock, and treat the double-digit two- and three-bedroom gains as a separate line.
• Cap renewal growth where the law caps it. 0% on stabilized units through September 30, 2027, and no more than 8.38% on covered market-rate units.
• Carry a real vacancy loss. A 1.54% borough vacancy rate is a market statistic. A turnover in your building costs 48 days at today's pace, plus the owner-paid broker fee.
• Run the expense line at 5.3%, not 3%. Insurance and fuel are compounding faster than rent on every stabilized unit, as our 2026 operating-cost underwriting guide details.

Growth is where it has always been in this city: in a vacant exempt unit, a renovation that moves a one-bedroom toward the $5,436 average, or a lease expiring into a market with 5,015 listings. None of that is captured by trending the borough median forward.

The next two Corcoran reports will show whether September's slowdown in leasing was seasonal or structural. Manhattan's median first crossed $5,000 in February, which we flagged for owners at the time; if the fourth quarter brings the usual seasonal softening on top of 48-day marketing periods, the November and December medians will say how much pricing power landlords actually have.

Watch days on market before you watch rent. A rising median with lengthening marketing time is what September showed in Manhattan, and in Brooklyn the same pairing has already produced a month-over-month decline. Watch the listing count too: if inventory keeps falling, the scarcity price holds; if more units surface, the first thing to move is concessions, not the asking rent.

For stabilized buildings, the Rent Guidelines Board publishes its Price Index of Operating Costs and Income & Expense Study each spring ahead of its vote; this year's arrived in March and April before the June 25 decision. The 2027 editions will carry the first full year of costs against a 0% renewal, and they are the numbers a buyer of a stabilized building should be waiting for.
