What a Real Estate Consultant Does, and What It Costs in St. Louis

Revised August 21, 2026

Imagine it’s a Sunday afternoon and you’re at the kitchen table in Richmond Heights with a legal pad, trying to decide whether to sell the house your mother left you or rent it out for five years. You don’t need a sign in the yard. Not yet. You need somebody to tell you which of those two things is the smarter move.

That is a different purchase than hiring an agent, and people around the metro make it more often than you’d think. A landlord in St. Peters wants a second opinion on whether a fourplex actually pencils. A couple in Cottleville wants to know if the addition they’re drawing will ever come back at resale. Somebody in Edwardsville inherited nine acres and has no idea what it’s worth to anyone but a farmer.

What all of them are shopping for is advice, priced as advice. That’s the product a real estate consultant sells. Here is what the work actually is, how flat-fee and hourly pricing compares with a percentage, and — the part almost nobody spells out — which of those services legally requires a license in Missouri and in Illinois.

What is a real estate consultant vs. realtor?

A real estate consultant sells you advice for a fee. A Realtor sells you a transaction for a commission. The consultant gets paid whether you buy, sell, or decide to sit still; the agent, in the traditional model, gets paid only when something closes. That one difference reshapes every incentive in the relationship.

The words are doing different jobs, too. Realtor is a registered membership mark of the National Association of Realtors, so it describes who somebody belongs to, not what they do. Every Realtor is a licensed agent; not every licensed agent is a Realtor. Consultant is the reverse — a description of the work with no credential attached to the word itself. Anybody can print it on a card.

So the title tells you almost nothing. What matters is the activity you are paying for, because in both Missouri and Illinois it is the activity, not the business card, that decides whether a license is required. That line is drawn in statute in both states, and it lands in a place most people do not expect.

What does a consultant actually deliver in a St. Louis deal?

Four things, mostly: a written opinion of what a property or a plan is worth, a strategy for a decision you have to make, negotiation preparation, and a portfolio review for people who own more than one door. Each one ends in a document, not a closing date.

Valuation opinion. A pricing analysis of what your property would likely bring, with comparable sales, condition notes and the assumptions written down. In statute this is a comparative market analysis or a broker price opinion. It is not an appraisal, and both states say so in black letter law.

Strategy work. Sell now or in three years. Rent it or list it. Subdivide the nine acres or sell them whole. Which of the four rentals to unload first. Which $18,000 of work to do before listing and which $18,000 to skip because it never comes back in that submarket. The deliverable is numbers, stated assumptions and a recommendation you can hand to your accountant.

Negotiation preparation. Reviewing an offer you already have in hand, building your counter, deciding what to concede and what to hold. Note this one. It is the service most likely to cross a licensing line, and the Missouri section below explains exactly why.

Portfolio and investment review. Rent roll analysis, cash-on-cash return, refinance versus sell, whether your exposure is stacked in one county. An owner holding rentals in both St. Louis County and Madison County, Illinois is running two different tax and regulatory environments at once, and that is precisely the kind of thing a review is for.

There is a fifth bucket that shades into a different job entirely: feasibility and entitlement advice on a project, which is closer to what a real estate developer does in St. Louis than to anything a listing agent handles.

How does a real estate consultant charge, and what does it cost?

Three ways: an hourly rate, a flat fee for one named deliverable, or a monthly retainer. Nobody publishes a fee schedule. Neither the Missouri Real Estate Commission nor the Illinois Department of Financial and Professional Regulation sets, caps or tracks consulting fees, and no trade body surveys them, so any range you see quoted online is somebody’s estimate rather than measured data.

What you can measure is the thing consulting competes against. A survey of 806 agents published by Clever Real Estate on June 17, 2025 put the average total commission at 5.44% of sale price nationally, up from 5.32% the year before, with the seller’s side at 2.77% and the buyer’s side at 2.67%. On a $300,000 house that is about $16,320 in total, roughly $8,310 on one side. Those are national averages from an industry survey, not a St. Louis figure and not a rule. Rates are negotiable and always have been.

Set that next to a fee. Twenty hours of advice at $100 an hour is $2,000. A flat fee for one written valuation opinion is a single number, agreed in advance, that does not move if the house sells for more. The trade shows up clearly once the two sit side by side: a percentage scales with the price of the asset, a fee scales with the hours of thinking. Neither is cheaper in the abstract. It depends on which one your situation actually needs.

Ask for the engagement letter before you agree to anything, and read three lines in it: what the deliverable is, when it arrives, and whether the fee credits against a commission if you later list with the same firm. Somebody who will not put scope and a date in writing is selling you a conversation.

When does paying for advice beat paying a percentage?

When the decision is worth more than the transaction. That is the whole test. If your real question is should I do this at all, a commission is a strange way to buy the answer, because a commission only exists if you say yes.

Five situations where a fee tends to win. You are not sure you should transact at all. You already have the buyer — a sibling, a neighbor, the tenant who wants to buy the duplex — so there is nothing to market. You own several properties and the question is which one to sell, not how to sell it. The property is odd: nine acres in Jefferson County, a mixed-use storefront with two apartments over it, a former church. Or you are a confident negotiator who needs preparation rather than representation.

And where it loses. If you need the listing syndicated, photographed, shown on Saturdays and pushed hard for six weeks, that is brokerage. It is labor, not analysis, and a percentage buys a great deal of it. Paying an hourly rate for showings would be an odd way to spend money.

Unrelated, and we know it — the gutters can wait, the roof can’t.

Which of these services needs a real estate license in Missouri?

Missouri draws the line at activity, not job title. Section 339.010 of the Revised Statutes of Missouri defines a real estate broker as anyone who, for compensation, does or attempts to do any of ten listed things. Two of them catch consultants: assisting or directing in the procuring of prospects calculated to result in a sale, exchange, lease or rental, and assisting or directing in the negotiation of any transaction calculated or intended to result in one.

Read those two clauses slowly, because they are the whole answer. Building a financial model, reviewing a rent roll, or explaining what prices have been doing in Webster Groves is not on the list. Sitting in on the negotiation and steering it, for a fee, is. So is lining up a buyer. The analysis sits outside the statute; the involvement does not.

The consequences are not theoretical. Section 339.020 makes it unlawful to act as a real estate broker, broker-salesperson or salesperson, or to advertise or assume to act as such, without a license first procured from the commission. Section 339.170 makes a knowing violation of those sections a class B misdemeanor. The commission in question is the Missouri Real Estate Commission, which sits in the Division of Professional Registration inside the Missouri Department of Commerce and Insurance, and it publishes a public license lookup.

Section 339.010 also carries an exemption list, and one entry matters a great deal to anybody shopping for advice: services rendered by an attorney in the performance of their duty as an attorney. A real estate lawyer can advise you on your deal without holding a real estate license. Court-appointed fiduciaries, government officials acting officially, and owners dealing in their own property are exempt as well.

Valuation carries its own rule. Section 339.501 makes it unlawful to act as a real estate appraiser in Missouri without a license or certificate from the Missouri Real Estate Appraisers Commission, a requirement in force since July 1, 1999. Its exemption list specifically covers any licensed real estate broker or salesperson who prepares a comparative market analysis or a broker price opinion. Notice how that is worded. The exemption is written for licensees. Someone with no license at all does not sit inside it.

Does a consultant need a license in Illinois?

Illinois is blunter, and it names valuation directly. Under the Real Estate License Act of 2000, at 225 ILCS 454/1-10, the definition of broker includes anyone who, for another and for compensation, prepares or provides a broker price opinion or a comparative market analysis. Charging a separate fee for an opinion of value in Illinois is brokerage by definition.

The carve-out proves the point. The Act says that work is not treated as a comparative market analysis or a broker price opinion if no compensation is paid other than compensation based on the sale or rental of the property — in other words, the free pricing opinion an agent hands over while chasing a listing. The moment a check is written for the analysis itself, it lands squarely inside the licensed definition.

Section 10-45 of the same Act then dictates what the document has to contain: the intended purpose, a description of the property, the methodology used, the assumptions and limiting conditions, a disclosure of any existing or contemplated interest the broker holds in the property, and the preparer’s name, license number and signature. It also requires this disclaimer in writing: “This is a broker price opinion/comparative market analysis, not an appraisal of the market value of the real estate, and was prepared by a licensed real estate broker or managing broker who was not acting as a State certified real estate appraiser.”

One more Illinois limit is worth knowing before you pay for one. Section 10-45 permits a broker price opinion for buyers, sellers, lienholders and parties conducting due diligence, but not as the primary basis for determining market value for a mortgage loan origination. If a Metro East lender needs a value, it needs an appraisal. Licensing on that side of the river runs through the Illinois Department of Financial and Professional Regulation, which issues the Real Estate Broker, Real Estate Managing Broker and Residential Leasing Agent credentials and maintains its own public lookup. Illinois exempts attorneys too, at Section 5-20, for services rendered in the performance of an attorney’s duty as an attorney at law.

Is the consultant on your side, or neutral?

This is the sharpest difference across the river, and it explains a lot about why people pay separately for independent advice. Illinois presumes representation. Missouri does not.

In Illinois, 225 ILCS 454/15-10 provides that licensees shall be considered to be representing the consumer they are working with as a designated agent for that consumer, unless a written agreement between the sponsoring broker and the consumer establishes a different relationship, or the licensee is performing only ministerial acts. The default setting is agency.

In Missouri, transaction brokerage is a full statutory relationship of its own. Section 339.755 lets a transaction broker provide real estate service to any party in a prospective transaction without an agency or fiduciary relationship to one or more parties. The duties are real but narrow: perform the agreement, exercise reasonable skill, care and diligence, present offers in a timely fashion, disclose adverse material facts, account for money and property, and advise the parties to seek expert advice on matters beyond the broker’s expertise. Loyalty is not on that list.

Missouri also hands you a piece of paper about it. Section 339.770 requires that in a residential transaction, at the earliest practicable opportunity during or following first substantial contact with someone who has not signed a written services agreement, the licensee provide the current broker disclosure form prescribed by the Missouri Real Estate Commission. It is short, it is easy to sign without reading, and it is the page that tells you who the person across the table actually works for. Read it before you talk numbers.

A consultant you pay directly is under contract to you and to nobody else, which is the honest appeal of the model. Just be clear about which relationship you are in, and get it in writing rather than assuming it.

Where is the line between an opinion of value and an appraisal?

An appraisal is a licensed or certified appraiser’s opinion of value, and it is what a lender orders. A broker price opinion or comparative market analysis is a real estate licensee’s pricing opinion, and both Missouri and Illinois state in statute that it is not an appraisal. Same subject, entirely different legal weight.

That matters the moment money moves. Illinois writes the limit into Section 10-45, which bars using a broker price opinion as the primary basis for market value in a mortgage loan origination and requires the disclaimer quoted above. Missouri approaches it from the other side, exempting licensees who prepare a comparative market analysis or broker price opinion from appraiser licensure under Section 339.501 rather than treating the two as the same product.

The practical version: a consultant’s number is excellent for deciding what to do and useless for binding anyone. No lender, no county assessor and no court is obliged to accept it. If the number has to stand up to somebody else, you want the other document — and what a home appraisal involves in St. Louis walks through how that process runs.

What this looks like from the consultant’s side of the desk

The economics of advisory work run backwards from brokerage, and that is what makes the trade hard. A listing agent’s pricing opinion is free, given away by the hundreds every February and March across St. Louis County and St. Charles County, because it is the thing that wins listings. So a consultant is trying to charge for the exact deliverable the rest of the market uses as a loss leader. That is the complaint operators trade with each other — you are competing with free. The offset is that fee revenue does not evaporate when a deal dies in inspection, and it does not wait on a title company to fund. The good ones are ruthless about scope: a written engagement, one named deliverable, a date, and a fee that does not change if the client ultimately does nothing. The ones who struggle slide back into free advice, hoping it turns into a listing. And since almost nobody searches “real estate consultant” until the week they need one, being listed, complete and reachable locally is the difference between getting that call and never hearing about it. Claiming a profile and getting listed on St Louis Near Me Directory is a small piece of that.

What should you ask before you sign an engagement letter?

Six questions, in this order. What exactly am I getting, in writing, and by what date? Are you licensed, and in which state? Are you acting as my agent, as a transaction broker, or as neither? Do you receive anything else if I transact — a referral fee, a commission, a rebate? Does this fee credit against a commission if I list with you later? And who else pays you anything on this property?

Check the license yourself rather than taking a word for it. Missouri licensees are searchable through the Division of Professional Registration, Illinois licensees through the Illinois Department of Financial and Professional Regulation. Both lookups are free and take about a minute.

Get the state right, too. A duplex in Belleville is Illinois work and a bungalow in Kirkwood is Missouri work, and an adviser handling both sides of the river needs to be licensed in both states for any activity that requires a license in each. Plenty of metro professionals are dual-licensed. Plenty are not, and it is a fair question to ask on the first call.

One last sorting step. If what you actually need is somebody to market and sell the house rather than advise you about whether to, that is a different shopping trip — how to choose a real estate agent in St. Louis covers that side of it.

Frequently asked questions

What does a real estate consultant do?

A real estate consultant gives paid advice about property decisions instead of brokering a sale. Typical work includes a written opinion of value, a sell-versus-rent analysis, negotiation preparation, feasibility review on a small project, or a portfolio review for someone who owns several rentals. The deliverable is a document and a recommendation, not a signed contract and a closing date.

What is the difference between a real estate agent and a real estate consultant?

An agent is licensed to broker transactions and is usually paid a commission when one closes. A consultant is paid a fee for analysis whether or not anything closes. Plenty of people hold both roles. The distinction that carries legal weight is the activity rather than the title: in Missouri and Illinois, negotiating or valuing property for a fee is licensed work.

What does real estate consulting do?

Real estate consulting produces a decision, not a transaction. You hire it when the open question is whether to act at all — sell now or in three years, rent or list, subdivide or sell whole, keep the fourplex or trade out of it. The output is a written analysis with numbers, stated assumptions and a recommendation you can hand to your accountant or attorney.

How much does a real estate advisor cost?

There is no published fee schedule. Neither the Missouri Real Estate Commission nor the Illinois Department of Financial and Professional Regulation sets or tracks consulting rates, so treat any quoted range as an estimate rather than a standard. Fees come three ways: hourly, a flat fee for one named deliverable, or a monthly retainer. Ask for the engagement letter, the scope and the delivery date first.

Is $100 an hour good for consulting?

It depends entirely on what the hour buys. Compare it against the alternative. Clever Real Estate’s June 17, 2025 survey of 806 agents put the average total commission at 5.44% of sale price, roughly $16,300 on a $300,000 home. Twenty hours at $100 comes to $2,000. The real test is whether the advice changes the outcome by more than it costs.

How much commission does a realtor make on a $300,000 house?

At the 5.44% average total commission reported in Clever Real Estate’s June 17, 2025 survey of 806 agents, a $300,000 sale generates about $16,320 in total commission, split between the listing side and the buyer side. That is a national average from an industry survey. Rates are negotiable and vary by brokerage, so a St. Louis deal can land well above or below it.

How much does a real estate agent make on a $300,000 house?

Much less than the total commission suggests. The same June 2025 survey put the seller’s side at 2.77% and the buyer’s side at 2.67%, so one side of a $300,000 sale is roughly $8,300 gross. The agent then splits that with their brokerage and pays self-employment taxes, MLS dues, marketing and insurance out of what remains.

Is it free to hire a real estate agent?

No. It has never been free. The cost was historically folded into the sale price and paid at closing out of the seller’s proceeds, which made it invisible rather than absent. Buyers in both Missouri and Illinois now sign a written agreement setting their agent’s compensation before touring homes. Somebody pays it; the only questions are who writes the check and whether it was negotiated.

What are the disadvantages of using a consultancy?

You pay whether or not anything happens, and you may pay twice if you later hire a brokerage for the same property. Advice is not representation: a consultant who is not your agent owes you no fiduciary duty of loyalty. And a pricing opinion is not an appraisal, so no lender, county assessor or court is bound by the number it lands on.
