Walk through any NYC commercial real estate transaction at scale and you will quickly realize the public listings on CoStar and LoopNet are the visible tip of a much larger market. Beneath the on-market layer sits a denser, more consequential off-market layer where trophy multifamily, ground-lease fee positions, conversion candidates, and irreplaceable retail corridors quietly change hands. Understanding the difference between an on-market and off-market commercial property in New York City — and why a seller would pick one channel over the other — is the foundation of every serious buy or sell decision in this market.
What an on-market NYC commercial sale actually looks like
An on-market commercial sale in New York City typically begins with the seller engaging a sell-side brokerage on an exclusive listing agreement (often 6 to 12 months). The brokerage prepares an offering memorandum, builds a marketing site, places the deal on CoStar and LoopNet, blasts the REBNY broker community, runs a property tour calendar, and works through a structured call-for-offers — usually with a defined bid date, formal best-and-final round, and a closing exclusivity awarded to the strongest bidder.
Listing on LoopNet or CoStar is the most visible signal that a deal is on-market. So is a broker sign on the building, a deal-specific microsite, or a public press release announcing the marketing campaign. The seller is intentionally inviting the entire qualified buyer universe — sometimes 200 or 300 names — to compete for the asset.
The point of an on-market process is price discovery through competition. In a hot Manhattan multifamily or development-site cycle, that competition can produce outlier-high clearance prices that no private negotiation would have matched. The trade-off: the seller surrenders information control, tenants and lenders learn about the sale, and a failed process leaves a permanent scar on the asset that every broker in the market remembers.
What an off-market NYC commercial sale actually looks like
An off-market or private sale runs in almost the exact opposite shape. The seller engages a single, deeply trusted broker — at Skyline Properties, this is typically Robert Khodadadian or a senior member of the team — who prepares a confidential Broker Opinion of Value (BOV) and assembles a hand-picked invite list of four to twelve qualified buyers. There is no CoStar listing. No LoopNet flyer. No public signage. No press release. Tenants, lenders, partners, and competitors learn nothing until the deal is signed and recorded on ACRIS.
Buyers receive a confidential teaser, sign a non-disclosure agreement, and only then see the address, the rent roll, and the underwriting package. Indicative offers are negotiated, not auctioned. The seller selects the strongest fit on price and execution certainty and grants 30 to 60 days of exclusivity to close. The whole cycle from origination to closing typically runs 90 to 180 days — often faster than a public process because there is no marketing period to burn.
Off-market is how landmark Manhattan trades have been transacting for decades. Skyline alone has brokered some of the most consequential private trades of the last cycle — 6 East 43rd Street ($135M to Vanbarton Group for a 441-unit office-to-residential conversion), 101 Greenwich Street ($105M to Metro Loft / Nathan Berman), 530 West 25th Street ($72M in Chelsea), 236 Fifth Avenue ($65M 99-year ground lease), and 131-133 Prince Street ($50M record SoHo retail) — every one of them outside the public listings channel.
Why a NYC seller chooses on-market vs. off-market
The single biggest determinant of channel choice is the seller's tolerance for information leakage. Tenants, lenders, partners, employees, and the broader market all behave differently when they know an asset is for sale. Sellers who can absorb that signaling cost — and want maximum competitive bidder tension in return — choose on-market. Sellers who cannot, do not.
On-market makes sense when
The asset is institutional, stabilized, has no tenant-continuity sensitivity, and the seller wants the widest possible bidder pool to maximize headline clearance price. Think a fully stabilized 100-unit Class B Manhattan multifamily building with manageable rent regulation exposure, no pending Local Law 11 work, and a clean DHCR registration history. Sellers in 1031 timing flexibility, with no partner-consent issues, and a willingness to wait 6 to 9 months for the marketing cycle to play out, are natural on-market sellers.
Off-market makes sense when
Almost every other situation. Owners with rent-stabilized tenants who will get spooked. Partnerships with right-of-first-refusal language and lender consent requirements. Family-office sellers transacting around generational transfer, estate planning, or charitable structures. Buildings with 467-m or 421-a abatement complexity that confuses public underwriters. Development site assemblages where any public footprint blows up the parcel pricing. Ground-lease fee positions where confidentiality around lease economics is paramount. In Manhattan above the $20M threshold, the default is off-market and on-market is the exception that requires justification.
How buyers experience the on-market vs. off-market difference
From the buyer side, the two channels feel completely different. On-market deals arrive in your inbox through CoStar alerts, REBNY broker mailers, or LoopNet saved searches. You compete against a wide field, often with limited time for diligence and limited ability to customize terms. Pricing is a function of where the marginal bidder lands — sometimes irrationally high, sometimes broken low when no one shows up.
Off-market deals arrive through a phone call from a broker who already knows your buy box. The competitive set is small. You have time to underwrite carefully, negotiate term flexibility, and structure the close around your 1031 calendar or fund cycle. But you only get access if you have done the relationship work — proof of funds on file, recent closings on your tombstone sheet, a tight written mandate, and a reputation for never re-trading without ironclad cause.
The bias toward on-market deal flow is one of the most common mistakes new NYC commercial buyers make. CoStar and LoopNet show you a subset of the market, often the subset other buyers have already passed on. Buyers who confine themselves to public channels are systematically losing to better-networked competitors. The Skyline buyer network exists precisely to solve this — to give qualified buyers structured access to the off-market layer the public databases can never surface.
Does on-market or off-market clear at a higher price?
The honest answer that veteran NYC brokers will give you: it depends on the cycle. In hot, liquid markets (Manhattan multifamily 2014–2015, development sites 2021), on-market processes occasionally produce outlier-high prints because bid wars push pricing beyond any private negotiation. In slow or balanced markets, off-market clears at or above public-process pricing because the seller can attach customized terms — tenant continuity covenants, deferred closing, leaseback, structured carve-outs — that have real economic value to the right buyer.
Across cycles, the spread between on-market and off-market clearance prices on comparable Manhattan assets is typically inside 3–7%, sometimes inside 2%. The persistent buyer narrative that off-market means cheap is mostly myth. What changes is the variance of outcomes. On-market processes have wider variance: occasional bid wars high, occasional broken processes low. Off-market processes have tighter variance around fair value, with the seller controlling all the downside risk.
Which NYC asset classes lean on-market vs. off-market
- Manhattan multifamily above $20M — heavily off-market. Tenant continuity, rent regulation sensitivity, partner consents all push private.
- Outer-borough multifamily under $10M — more often on-market. Smaller, less institutional buyer universe, less confidentiality cost.
- Ground lease fee positions — almost exclusively off-market. Tiny buyer universe of family offices, pension funds, and Safehold-style platforms.
- Development sites and assemblages — off-market until the assemblage is complete. Any public footprint kills the assemblage premium.
- Conversion candidates (Class B office) — off-market. Specialized buyer universe, 467-m timing complexity, seller privacy.
- Trophy retail — Madison, Fifth, SoHo, Bleecker — almost always private. Skyline brokered 131-133 Prince Street ($50M) and many others quietly.
- Stabilized Class A office (newer construction) — split. Big institutional trades sometimes run public, often private depending on seller.
- Hotels — usually private given operational continuity risk.
How NYC buyers should structure access to both channels
Serious buyers should never confine themselves to one channel. The right posture is to maintain disciplined access to both: a CoStar or LoopNet subscription for on-market situational awareness, and two to four deep broker relationships for off-market deal flow. The on-market layer tells you where the market is pricing today. The off-market layer is where you actually transact.
What a broker needs from you to route off-market deals is straightforward: a one-page written buy box (asset class, submarket, ticket size, return thresholds, structure), demonstrated execution (recent closings, named lender, proof of funds), and a reputation for fairness. Skyline maintains an active buyer network of family offices, institutional sponsors, and private capital that we route mandates to first. Buyers who are not in that network are seeing a smaller market than the buyers who are.
Skyline's perspective on running both processes
Skyline Properties has closed more than $976 million in NYC commercial real estate transactions across both channels — confidential single-broker processes for sellers who require privacy, and competitive public processes when the asset and the cycle support it. Robert Khodadadian's view is unequivocal: the question is never whether off-market or on-market is better in the abstract; it is which channel is better for this asset, this seller, this moment in the cycle. A confidential BOV is the right starting point for any owner weighing the decision. It is no-cost, no-obligation, and gives the seller a defensible benchmark before deciding whether and how to bring the asset to market — and through which channel.
Frequently asked questions
- Is off-market commercial real estate in NYC always cheaper than on-market?
- No. The spread between on-market and off-market clearance prices on comparable NYC commercial assets is typically inside 3–7%, and in hot cycles on-market processes occasionally produce outlier-high prints that no private negotiation matches. The advantage of off-market is execution certainty, customized terms, and information control — not headline discount.
- Can I find off-market NYC commercial properties on LoopNet or CoStar?
- By definition, no. If a deal appears on LoopNet, CoStar, or Crexi, it is on-market. The off-market channel exists precisely because the seller has chosen not to publicly market the property. The only way to access off-market NYC deals is through relationship-driven brokers, direct owner outreach, or capital-network introductions.
- What percentage of NYC commercial trades happen off-market?
- It varies by asset class and ticket size. In Manhattan multifamily above $20M, the off-market share routinely runs 40–60% by dollar volume. In ground-lease fee positions and development-site assemblages, it is essentially 100%. In outer-borough small multifamily and stabilized retail under $5M, the public-listings share is much higher.
- Should I, as a seller, choose on-market or off-market for my NYC building?
- It depends on tenant sensitivity, partnership structure, timing flexibility, asset class, and the current cycle. A confidential Broker Opinion of Value from Skyline is the right first step — it surfaces pricing range, optimal channel, and likely buyer universe without any public footprint and with no obligation to transact.
