Consultant vs. Broker: What a Fee-Based CRE Advisor Actually Does for a $3M–$50M Owner

Most owners of a $5 million to $50 million building in New York have worked with brokers for their entire ownership and have never once been offered advice that was not attached to a transaction. That is not a criticism of brokers. It is a description of the market: the advice that exists for small and mid-size owners is almost entirely delivered by people who are paid when something closes.

Consulting is a different job. Here is what the difference is, in practical terms, and when each one is the right call.

What a broker is paid to do

A leasing broker is paid a commission — typically a percentage of the total lease value — when a lease is signed. A sales broker is paid a percentage of the price when a building closes. Both are execution roles: find the counterparty, run the process, get to signature. Good brokers are worth every dollar for exactly that.

The incentive is also exactly what it sounds like. A broker earns nothing from "don't sign this lease," "hold the space for a better tenant," "divide the floor before you market it," or "this building should not be sold this year." Those are frequently the right answers, and they are structurally unavailable from someone whose income depends on the opposite.

What a consultant is paid to do

A fee-based consultant is paid for analysis and advice, by the hour, by the project, or on a monthly retainer, regardless of whether any deal happens. The scope is the building, not the transaction:

1. Pricing. What every space is worth today, to whom, and on what basis.
2. Product. Whether the unit mix, condition and lease form match the tenants who are actually active.
3. Lease economics. Which concessions to offer, which to refuse, and what each clause costs over the term.
4. Rent roll strategy. Renewals, expirations, who to keep and who to let go.
5. Capital decisions. Whether to divide, renovate, refinance, hold or sell — with numbers, not opinions.
6. Representation in the room. Sitting beside the owner in negotiations with tenants, brokers, lenders and buyers, with no commission on the other side of the table.

A broker is paid to get you to a signature. A consultant is paid to tell you whether you should sign.

The 13-year view

I spent 13+ years working every day in NYC real estate — on the landlord side of hundreds of leases and dozens of sales — before moving to a consulting-only model. The reason was simple: the most valuable conversations I had with owners were the ones that did not result in a commission, and there was no way to be paid for them inside a brokerage.

Ratner Consulting takes no listings and earns no commissions. That is not a marketing line; it is the reason the advice can be straight.

When an owner needs which

You need a broker when you have decided what to do, the product is right, the price is set, and you need someone to find the counterparty and run the process.

You need a consultant when you are not sure what to do; when a floor has sat vacant and you do not know why; when a renewal is coming and you do not know what to ask for; when you are considering selling, refinancing or renovating and want the numbers before you commit; or when you simply want a second opinion from someone with no stake in the answer.

You often need both. Consulting sets the strategy, pricing and terms. A broker executes. The consultant's fee is a fraction of the value it protects, and the broker's commission is earned on a deal that was structured correctly from the start.

What it costs

A consulting engagement for a single building is priced against the size of the decision, not the size of the building. A lease-review or pricing engagement is a few thousand dollars. A full building strategy with ongoing advisory is a monthly retainer. There is no long-term contract; owners stay because the income growth — 50–300% across 100+ engagements — is visible in their own rent roll within the first year. Here is how a landlord engagement works.
