In commercial real estate sales, the seller pays the brokerage commission — a negotiated percentage of the sale price, set in the listing (or exclusive sales) agreement and paid at closing out of the seller's proceeds. Typical sale commissions scale down with deal size: 4–6% on small deals, 2–3% in the low-to-mid millions, and 1–2% or less at institutional scale, with the fee split between listing and buyer-side brokers when two are involved. Buyers rarely write a commission check directly, though the fee is economically embedded in every price. This guide explains how the structures actually work — co-brokerage splits, buyer representation, retainers, and how a confidential single-broker off-market process changes the fee economics for both sides.
Who pays, how much, and when
The commission lives in the agreement between the seller and the brokerage — an exclusive right to sell or exclusive agency agreement specifying the percentage, the term, carve-outs, and a tail period covering buyers introduced during the engagement. It is earned per the contract and paid at closing on the settlement statement, out of sale proceeds. No closing, no fee: commercial sale brokerage is overwhelmingly success-based, which is why brokers filter hard for deals that can actually close.
Percentages are negotiated, not fixed — antitrust law forbids standard rates — but the market clears in recognizable bands that scale down as price scales up: roughly 4–6% on deals under $5M, 2–3% through the low tens of millions, and 1–2% or less at institutional size. The scale-down reflects effort economics: selling a $100M building is not twenty times the work of a $5M building. On Skyline-scale transactions — the $135M sale of 6 East 43rd Street, the $72M sale of 530 West 25th Street — fees are bespoke, structured to the mandate's complexity and confidentiality requirements.
Co-brokerage: how the fee splits when two brokers are involved
When a marketed deal closes with a buyer represented by their own broker, the listing broker typically shares the commission with the buyer's broker — the co-brokerage split, commonly 50/50 but negotiable. The seller's total cost usually does not change; the pie divides. This is why buyers can obtain professional representation at little or no direct cost on marketed deals, and why the standing advice to NYC buyers is to be represented: the economic seat is effectively pre-paid. Inside each brokerage, a further internal split divides the house share between the firm and the individual agents — invisible to the client but a real driver of broker behavior.
One structural note: in commercial co-brokerage, the buyer's broker is compensated through the transaction but negotiates for the buyer. Sophisticated buyers keep that alignment honest by defining the relationship in writing — and by remembering that a broker paid only on closing has an interest in a closing, which is one argument for the retainer structures covered below.
Buyer representation: co-broke, seller-paid, or retainer-plus-success
Dedicated buyer-side engagements are compensated three ways. First, the co-brokerage share on marketed deals, as above. Second, on off-market transactions the buyer's broker who sources the deal typically negotiates a seller-paid fee into the transaction — the seller nets a sale without running a process, and the fee recognizes that the broker manufactured the deal. Third, for structured acquisition searches — a family office hunting a specific asset profile, a 1031 exchanger on a statutory clock — retainer-plus-success structures apply: a monthly or upfront retainer compensating the search itself, credited against a success fee at closing.
The retainer model aligns incentives on hard searches: the buyer gets a broker economically able to say 'pass' for months, and the broker gets paid for genuine sourcing work rather than only for closings. Skyline runs formal acquisition mandates on all three structures depending on the search. What buyers should never do is go unrepresented to save a fee they were never going to pay — the analysis in what commercial real estate brokers actually do shows where the representation earns its keep.
How off-market single-broker processes change the fee math
In a confidential off-market sale, one broker runs the entire transaction — sourcing the buyer directly from relationships rather than marketing the asset. The fee economics change in three ways. First, concentration: a single negotiated fee replaces the listing-plus-co-broke stack, often producing a lower total commission load at the same or better execution. Second, accountability: one broker owns pricing, buyer selection, negotiation, and closing — there is no split-incentive seam in the middle of the deal. Third, and most economically significant: the confidentiality itself has value that dwarfs the fee variance — no tenant unrest, no lender questions, no public re-pricing if a process stalls, no signaling to the market that the owner is a seller.
Skyline's practice is built on this model. The $105M sale of 101 Greenwich Street to Quantum Pacific and Metro Loft and the record $50M SoHo retail co-op sale at 131-133 Prince Street ($16,667/SF, to Acadia Realty Trust) were relationship-driven transactions, not marketed processes. Sellers weighing the models should read how off-market deals get sold in NYC and the confidential disposition guide.
Negotiating the fee: what actually matters
Sellers negotiating a commission should focus less on the headline percentage and more on what it buys. The questions that matter, in order:
- Confirm who personally executes — a point of commission is irrelevant next to whether the senior principal or a junior team runs your deal; name the individual in the agreement.
- Test the fee against the strategy — a confidential single-broker process, a targeted quiet marketing effort, and a full public campaign are different products with different fee logic; price the one you are actually buying.
- Negotiate the tail and carve-outs — the protection period for introduced buyers and any excluded parties you sourced yourself matter more in dollars than a quarter-point of rate.
- Align term with accountability — a shorter exclusive with renewal beats a long lock-up; brokers confident in execution accept accountability checkpoints.
- Weigh net proceeds, not fee minimization — a broker whose access and negotiation add 3–5% to the price is cheap at any market commission; the how we price methodology shows where that increment comes from.
The same logic runs in reverse for buyers structuring retainers: pay for sourcing you can verify, credit retainers against success fees, and define the search in writing.
How Skyline approaches fees
Skyline Properties structures fees the way we structure deals: bespoke, success-weighted, and aligned with what the client is actually buying — which, in our off-market investment sales practice, is confidentiality, direct buyer access, and senior execution on every transaction. Every engagement is priced against the specific mandate, and every fee conversation starts with the same question we ask about the asset: what does the net outcome look like?
Sellers can begin a confidential conversation through sell commercial property NYC; buyers can join the buyer network or discuss a retainer-plus-success acquisition mandate directly — (212) 537-9239.
Frequently asked questions
- Who pays the broker fee when buying commercial real estate?
- The seller, in nearly all cases. The commission is set in the seller's exclusive sales agreement and paid at closing from sale proceeds; if the buyer brings their own broker to a marketed deal, the listing broker typically shares the fee via a co-brokerage split, so the buyer still pays nothing directly. The economic reality is that commissions are embedded in pricing — but as a matter of who writes the check, buyers generally do not. The exception: dedicated buyer-search retainers, which buyers pay for sourcing work and typically credit against a success fee.
- What is a typical commercial real estate commission percentage?
- Commissions are negotiated case by case — there is no legal standard rate — but the market clears in bands that scale down with deal size: roughly 4–6% on transactions under $5 million, 2–3% from $5 million to $25 million, and 1–2% or less at institutional scale, where fees are often bespoke flat or hybrid structures. Complexity, confidentiality requirements, and expected marketing scope move the number within each band. On a $100 million transaction, even 1% is $1 million — which is why institutional fees compress.
- Can I avoid the broker fee by buying directly from the owner?
- You can avoid a commission line, but rarely the economics. Unrepresented direct deals in NYC tend to close at prices reflecting the absence of professional pricing discipline — sometimes in the buyer's favor, at least as often in the seller's — and the transaction risk (mispriced regulation, title and zoning surprises, broken negotiations) lands entirely on the principals. The recorded history is unambiguous: the largest, most sophisticated NYC owners use brokers on their biggest deals, because access, pricing, and execution are worth more than the fee.
- How do broker fees work on off-market deals?
- One broker typically runs the entire transaction, sourcing the buyer directly rather than marketing the property. The fee is a single negotiated commission — usually seller-paid at closing, sometimes structured into the price on buyer-sourced deals — often producing a lower total fee load than a marketed process's listing-plus-co-broke stack. The seller trades marketing exposure for confidentiality, speed, and certainty; the broker earns the fee by manufacturing a transaction that otherwise would not exist. Skyline-brokered deals from $50M to $135M closed on this model.
