When a practice owner signs a lease, they are almost always the least-represented person in the room. That is not a figure of speech. On the other side of the table, the landlord has a listing broker whose full-time job is to fill that building at the best terms for the owner, and an attorney who drafted the document to protect the owner's interests. Those two have negotiated hundreds of these. You have negotiated, at most, a handful — and years apart.

That imbalance has a name in commercial real estate: information asymmetry. One side knows what the space down the street is really renting for, what concessions the landlord quietly gave the last tenant, and which clauses are boilerplate versus which ones are load-bearing. The other side knows medicine. A tenant representative — a broker who works only for tenants — exists to close that gap. This piece is a plain explanation of what that person actually does, how they get paid, and why, in most deals, hiring one costs the practice nothing.

The problem: the landlord has a whole team, and you have your gut

Read a lease cold and it looks like a fair, formal document. It is not written to be fair. It is written by the landlord's counsel to allocate risk, cost, and control toward the landlord — legally and routinely. Every ambiguity resolves their way. Every silence is a silence they chose.

The listing broker reinforces that. A listing broker is a good, honest professional who is paid by, and loyal to, the landlord. Their job is to lease the space at the highest rent and the fewest concessions the market will bear. When that broker is friendly and helpful — and they usually are — it is easy to mistake their help for representation. It is not. They cannot get you a lower number and get their client a higher one at the same time. Nobody can serve both.

So the typical practice owner walks into a negotiation with real money and real protections on the table, facing a coordinated professional team, armed with a rent quote and instinct. That is the setup a tenant rep is built to fix.

What a tenant rep actually does

The label sounds like "the person who finds you space." Finding space is the smallest part of it. The work that moves money happens after you have a building in mind.

Survey the real market, not the asking market. A tenant rep knows what comparable medical and dental space is actually leasing for — not the posted asking rate, but the effective rate after free rent, improvement dollars, and escalations are counted. That is the number you need and the one you cannot get on your own, because it lives in deals that already closed.

Run a process that creates competition. This is the core of the job. Instead of negotiating against one landlord who knows you have nowhere else to go, a tenant rep quietly puts your requirement in front of several buildings at once — a request for proposals. Now landlords are competing for your tenancy. The difference in leverage between "we are talking to your building" and "we are comparing four buildings" is the difference between paying the asking rate and setting the price. A practice negotiating alone almost never generates that competition, because generating it is a full-time, relationship-driven effort.

Negotiate the economics and the clauses. Owners tend to fixate on base rent because it is the one number they can see. A tenant rep negotiates the whole deal — the tenant improvement allowance that funds your build-out, the free-rent period, the annual escalations, the base year and expense caps on CAM, the renewal options, and the protective clauses that decide what happens when you want to sell or the landlord wants to redevelop. Those terms, taken together, routinely outweigh the headline rent over a full lease. If you want the clause-by-clause version, we wrote it out in how to read a medical office lease.

Manage the clock. Medical leases run on timelines that punish the unprepared — notice windows to exercise options, build-out schedules, the long runway a clinical space needs before you can see a patient in it. A tenant rep works backward from your open date so leverage does not quietly expire while you are busy running a practice. That timing discipline is its own form of savings; we made the case for it in early-renewal leverage.

Answer to one side. Everything above depends on a single structural fact: a true tenant rep has no listing agreement with the landlord and no divided loyalty. Their entire incentive is your outcome. That undivided position is the product.

How the commission actually works — and why you usually pay nothing

This is the part most owners get wrong, and it is the part that changes the decision.

When a landlord lists space, they agree in advance to pay a leasing commission, and that commission is built to cover both sides of the deal — a listing-side portion and a tenant-side portion. The money is already baked into the economics of the building whether or not you bring your own broker. If you show up without representation, the landlord's broker does not split that fee with anyone. They simply keep the whole thing.

Put plainly: the fee that would pay for your representation exists either way. The only question is whether it pays for someone working for you, or gets absorbed by the other side. When a tenant rep is involved, the landlord customarily pays the tenant broker's commission out of that same pre-agreed pool, split from the listing side — which is why hiring a tenant rep typically costs the practice nothing out of pocket.

That is not a loophole. It is simply how commercial leasing has been structured for decades. The counterintuitive result: going it alone to "save money" often saves nothing, because the commission is spent regardless — and you have given up the one professional whose job was to pull the deal toward you.

The trap: using the listing broker, or a "dual" agent

Because the listing broker is right there and eager to help, the path of least resistance is to just let them handle both sides. Sometimes it is framed as dual agency — one broker representing landlord and tenant at once.

Look at what that asks. The person negotiating your rent down is the same person paid to keep it up. The person who should be pushing for a larger improvement allowance is the one who promised the owner to give away as little as possible. Even with the best intentions, no one can advocate hard for two opponents in the same negotiation. At the exact moments that decide the deal, a dual agent has to go quiet — and quiet always favors the side with more information, which is not you. It is worth understanding this before someone offers, helpfully, to "represent you too."

What DIY leaves on the table

Handling it yourself is not reckless, and plenty of owners do it. But it is worth being honest about what it forfeits. Without representation you rarely generate real competition among buildings, so you negotiate from the weakest position — one landlord who knows you have no alternative. You benchmark against asking rates instead of the effective deals that actually closed, so you cannot tell a strong offer from a weak one. And you tend to win on the number you can see, the rent, while conceding the clauses you cannot yet feel — the escalators, the expense pass-throughs, the assignment language that surfaces years later when you try to sell the practice.

None of that shows up on signing day. It shows up in year three, or at your exit, when the terms are fixed and there is no one left to negotiate them.

The honest close

A tenant rep is not magic, and not every deal has dramatic room in it. But the structure of a lease negotiation is lopsided by default, and the fee to level it is usually already spent whether you use it or not. That is an unusual situation: the case for representation is strongest precisely because it typically costs the practice nothing.
