Work enough NYC commercial deals and you learn quickly that the public listings on CoStar and LoopNet are the visible edge of a much bigger market. Underneath sits the off-market layer, busier and higher-stakes, where trophy multifamily, ground-lease fee positions, conversion candidates, and retail on irreplaceable corridors change hands quietly. Every serious buy or sell decision in New York starts with knowing the difference between an on-market and an off-market commercial property, and why a seller would pick one channel over the other.
What an on-market NYC commercial sale actually looks like
An on-market sale in New York usually starts with the seller signing an exclusive listing agreement with a sell-side brokerage, often for 6 to 12 months. The brokerage writes an offering memorandum, builds a marketing site, puts the deal on CoStar and LoopNet, blasts the REBNY broker community, schedules property tours, and runs a structured call for offers. There's usually a set bid date, a formal best-and-final round, and exclusivity to close for the winning bidder.
A LoopNet or CoStar listing is the clearest sign a deal is on-market. So is a broker's sign on the building, a microsite for the property, or a press release announcing the marketing campaign. The seller is deliberately inviting every qualified buyer, sometimes 200 or 300 names, to compete for the asset.
The point of an on-market process is to find the price through competition. In a hot Manhattan multifamily or development-site cycle, that competition can produce clearing prices no private negotiation would have reached. The cost: the seller gives up control of the information, tenants and lenders find out about the sale, and if the process fails, every broker in the market remembers the asset as damaged goods.
What an off-market NYC commercial sale actually looks like
An off-market or private sale works almost the opposite way. The seller hires one broker they trust completely (at Skyline Properties, usually Robert Khodadadian or a senior member of the team), who prepares a confidential Broker Opinion of Value (BOV) and hand-picks four to twelve qualified buyers. There is no CoStar listing, no LoopNet flyer, no sign on the building, and no press release. Tenants, lenders, partners, and competitors hear nothing until the deal is signed and recorded in ACRIS.
Buyers get a confidential teaser and sign an NDA before they see the address, the rent roll, or the underwriting package. Offers are negotiated one on one; there is no auction. The seller picks the best fit on price and certainty of closing and grants 30 to 60 days of exclusivity to close. From first call to closing, the process usually takes 90 to 180 days, often faster than a public sale because there's no marketing period.
Landmark Manhattan buildings have traded this way for decades. Skyline Properties has brokered several of the largest 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 Quantum Pacific + 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). None of them went through the public listings channel.
Why a NYC seller chooses on-market vs. off-market
The biggest factor in choosing a channel is how much information leakage the seller can live with. Tenants, lenders, partners, employees, and the wider market all act differently once they know a building is for sale. Sellers who can absorb that cost, and want as much bidding pressure as possible in return, go on-market. Sellers who can't, don't.
On-market makes sense when
The asset is institutional and stabilized, tenant continuity isn't a concern, and the seller wants the widest possible bidder pool to push the headline price. Picture 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. A seller with room on 1031 timing, no partner-consent issues, and the patience to let a marketing campaign run 6 to 9 months is a natural on-market seller.
Off-market makes sense when
In almost every other case. Owners whose rent-stabilized tenants will get nervous. Partnerships with right-of-first-refusal language and lender consent requirements. Family offices selling around a generational transfer, estate planning, or charitable structures. Buildings with 467-m or 421-a abatement complications that confuse public-market underwriters. Development assemblages, where any public footprint blows up the price of the remaining parcels. Ground-lease fee positions, where the lease economics have to stay confidential. In Manhattan above $20M, off-market is the default, and going on-market is the exception you need a reason for.
How buyers experience the on-market vs. off-market difference
For a buyer, the two channels feel nothing alike. On-market deals land in your inbox from CoStar alerts, REBNY broker mailers, or LoopNet saved searches. You're bidding against a big field, usually with little time for diligence and little room to shape the terms. The price ends up wherever the marginal bidder lands: sometimes irrationally high, sometimes very low when nobody shows up.
Off-market deals come from a phone call from a broker who already knows your buy box. Few buyers are competing. You have time to underwrite carefully, negotiate flexible terms, and time the closing around your 1031 calendar or fund cycle. But you only get the call if you've 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 a very good reason.
Leaning on on-market deal flow is one of the most common mistakes new NYC commercial buyers make. CoStar and LoopNet show you part of the market, often the part other buyers have already passed on. Buyers who only look at public channels keep losing to better-connected competitors. That is why the Skyline Properties buyer network exists: to give qualified buyers structured access to the off-market deals the public databases never show.
Does on-market or off-market clear at a higher price?
Ask a veteran NYC broker and you'll hear it depends on the cycle. In hot, liquid markets (Manhattan multifamily in 2014–2015, development sites in 2021), on-market processes now and then produce outlier prices because bidding wars push past anything a private negotiation would reach. In slow or balanced markets, off-market deals clear at or above public-process pricing because the seller can offer custom terms (tenant continuity covenants, a deferred closing, a leaseback, structured carve-outs) that are worth real money to the right buyer.
Across cycles, the spread between on-market and off-market prices on comparable Manhattan assets usually falls inside 3–7%, sometimes inside 2%. The idea buyers keep repeating, that off-market means cheap, is mostly a myth. What differs is the range of outcomes. On-market results swing more widely, with the occasional bidding war on the high side and the occasional failed process on the low side. Off-market results cluster closer to fair value, and the seller controls the downside.
Which NYC asset classes lean on-market vs. off-market
- Manhattan multifamily above $20M: heavily off-market. Tenant continuity, rent regulation sensitivity, and partner consents all push it private.
- Outer-borough multifamily under $10M: more often on-market. The buyer pool is smaller and less institutional, and confidentiality costs less.
- Ground lease fee positions: almost always off-market. The buyer pool is a handful 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. A specialized buyer pool, tricky 467-m timing, and sellers who want privacy.
- Trophy retail on Madison, Fifth, SoHo, and Bleecker: almost always private. Skyline Properties brokered 131-133 Prince Street ($50M) and many others quietly.
- Stabilized Class A office (newer construction): split. Big institutional trades sometimes run public and often private, depending on the seller.
- Hotels: usually private, because of the risk to ongoing operations.
How NYC buyers should structure access to both channels
Serious buyers never limit themselves to one channel. Keep a foot in both: a CoStar or LoopNet subscription so you know what's happening on-market, and two to four close broker relationships for off-market deal flow. The on-market side tells you where the market is pricing today. The off-market side is where you actually buy.
A broker needs three things from you before routing you off-market deals: a one-page written buy box (asset class, submarket, ticket size, return thresholds, structure), proof that you close (recent closings, a named lender, proof of funds), and a reputation for fair dealing. Skyline Properties keeps an active buyer network of family offices, institutional sponsors, and private capital, and we take mandates to that network first. Buyers outside it are looking at a smaller market than the buyers inside it.
Skyline Properties' perspective on running both processes
Skyline Properties has closed more than $976 million of NYC commercial real estate through both channels: confidential single-broker sales for sellers who need privacy, and competitive public processes when the asset and the cycle call for one. Robert Khodadadian doesn't hedge on this. Asking whether off-market or on-market is better in general is the wrong question. The right one is which channel suits this asset, this seller, and this point in the cycle. For any owner weighing that decision, start with a confidential BOV. It's free, carries no obligation, and gives the seller a defensible benchmark before deciding whether to sell, how, and through which channel.
Frequently asked questions
- Is off-market commercial real estate in NYC always cheaper than on-market?
- No. On comparable NYC commercial assets, the spread between on-market and off-market prices usually falls inside 3–7%, and in hot cycles an on-market process will now and then produce an outlier price that no private negotiation would match. What off-market gives you is certainty of execution, custom terms, and control of information. It does not give you a headline discount.
- Can I find off-market NYC commercial properties on LoopNet or CoStar?
- By definition, no. If a deal shows up on LoopNet, CoStar, or Crexi, it is on-market. Off-market deals exist because the seller chose not to market the property publicly. The only ways into off-market NYC deals are brokers with the relationships, direct outreach to owners, or introductions through capital networks.
- What percentage of NYC commercial trades happen off-market?
- It depends on asset class and deal size. In Manhattan multifamily above $20M, the off-market share regularly runs 40–60% of dollar volume. In ground-lease fee positions and development-site assemblages, it is close to 100%. In small outer-borough multifamily and stabilized retail under $5M, far more trades go through public listings.
- Should I, as a seller, choose on-market or off-market for my NYC building?
- It depends on how sensitive your tenants are, your partnership structure, how flexible your timing is, the asset class, and where we are in the cycle. Start with a confidential Broker Opinion of Value from Skyline Properties. It gives you a pricing range, the channel that fits best, and the likely buyers, with no public footprint and no obligation to sell.
