The quick read: Before you hire a commercial mortgage broker, ask how and when they are paid, who pays them and whether any lender pays them too, where the fee will appear in your loan documents, which lender types they will approach and why, who reviews your file and who negotiates, what the exclusivity and tail terms say, and what you owe if no loan closes. Get every answer in writing: the federal rule that stops a home-loan originator from being paid by both sides does not cover business-purpose credit.
This page is the question list, not the fee guide or the ranking. For what brokers charge and how fee agreements are built, read how commercial mortgage broker fees work; for a criteria-based comparison of brokerages, read the best commercial mortgage brokers in 2026. Every question below works on any broker, including the brokerage that publishes this guide.
Why doesn't a commercial loan come with the broker-pay protections of a home loan?
A commercial loan does not come with those protections because Regulation Z, the federal rulebook that includes the limits on how home-loan originators are paid, does not apply to credit extended primarily for a business, commercial or agricultural purpose. What a homebuyer gets by default, a commercial borrower has to ask for, in writing, before signing.
The clearest gap is dual compensation. On a consumer loan secured by a dwelling, section 1026.36(d)(2) of Regulation Z says that when a loan originator receives compensation directly from the consumer, no loan originator may receive compensation from any other person in connection with that transaction, with limited exceptions, according to the Consumer Financial Protection Bureau's published text of the rule. Section 1026.3(a) takes business-purpose credit out of the regulation, so on a commercial loan Regulation Z will not ask whether your broker is also being paid by the lender. You have to.
One exception applies to SBA-guaranteed small business loans: on the 7(a) and 504 programs, the SBA writes its own disclosure rules for agents paid to help with an application. Those rules are covered in their own section below.
Which questions tell you how a commercial mortgage broker gets paid?
Four payment questions come first because they show what the broker is paid to do: how the fee is calculated and when each part is due, who pays it, whether any lender pays the broker anything on the same loan, and where the fee will appear in the documents you sign before and at closing.
- How is your fee calculated, and when is each part due? Ask for the formula (a percentage of the loan, a flat amount, hourly billing, a retainer, or a mix) and the trigger for each payment: signing the engagement, receiving a lender's term sheet, or the loan funding. Money due before a lender issues terms is spent whether or not the deal closes.
- Who pays you: me, the lender, or both? You want one named payer for each service. An answer of "both" is not automatically wrong, but it needs a written explanation of what each side is paying for.
- Will any lender pay you anything on my loan? That includes a referral fee, a share of the lender's origination fee, or any payment tied to the interest rate you accept. The answer you want is "no" or a dollar amount, written into the engagement letter.
- Where will your fee be written down? Ask where it appears at each stage: the engagement letter, any lender term sheet that references it, and the closing statement. A fee you can see on the closing statement is a fee you can check against the number you agreed to.
Which questions show whether a broker will actually shop your loan?
The shopping questions test whether a broker runs a real competition or sends your file to one familiar desk: ask which lender types they will approach for this deal and why, how they choose the specific lenders inside each type, and whether you approve every lender before your file goes out.
Lender types matter because appetite shifts between them. In the Mortgage Bankers Association's August 6, 2026 origination report, the dollar volume of loans originated for CMBS in the second quarter of 2026 was up 68% from a year earlier and loans for depositories were up 61%, while life insurance company loans fell 27% and loans for the GSEs, Fannie Mae and Freddie Mac, fell 17%. Ask which lender types the broker has placed loans with in the last two quarters and why each one fits your deal; this guide to what each lender type is built for explains the differences.
Ask how many lenders will see the file, but weigh the reasoning over the count. A broker should be able to say why each lender on the list fits your property, leverage and timeline, and should give you that list in writing before submission. The same list is what any tail clause in the agreement should be measured against.
Who reviews your file, and who negotiates the term sheets?
Ask who at the firm will read your file before any lender sees it and who will negotiate the term sheets that come back, because the person who sold you the engagement is not necessarily the person who checks the package, flags its weak points, or pushes back on a lender's first draft.
- Who reviews the package, and what do they check? A useful answer names the reviewer and the checks, such as whether the rent roll ties to the operating statement, whether sources equal uses, and whether the sponsor's liquidity and experience fit the request.
- Who negotiates, and which terms are in play? Rate is one term among several; leverage, recourse, reserves, prepayment and fees set what the loan really costs. For the clauses worth pushing on, see what to watch in CRE term sheets.
- How will competing quotes be presented? Ask for every offer side by side on the same basis, with each quote's index, spread and index date. For reference, the 10-year Treasury yield was 4.96% as of September 22, 2026 (FRED series DGS10) and the Secured Overnight Financing Rate (SOFR) was 3.87% as of September 23, 2026 (FRED series SOFR). A quote that names its index and date can be checked against prints like those; one that does not cannot.
What should you ask about exclusivity, tails and a loan that never closes?
Ask three contract questions before you sign: whether the engagement is exclusive and for how long, whether a tail clause lets the broker collect a fee after you part ways and on which lenders, and exactly what you owe, in dollars, if no loan closes. Those answers decide what changing course will cost.
- Is it exclusive? If so, ask for a fixed end date and named carve-outs for lenders you already work with, so a call to your own bank does not turn into a fee dispute.
- Is there a tail, and what triggers it? Ask how long it runs after the engagement ends and whether it is limited to lenders on the written submission list you approved.
- What do I owe if nothing closes? Get a dollar answer for each scenario: you walk away before terms arrive, a lender issues terms you decline, or the lender declines the loan. Ask which third-party costs, such as an appraisal or an environmental report, you would carry either way.
The fee guide linked at the top explains how these clauses work. If a broker cannot answer all three questions in a short paragraph, the agreement is not ready to sign.
What changes when the loan is SBA-guaranteed?
On an SBA 7(a) or 504 loan, broker pay is disclosed on a federal form: SBA Form 159, the Fee Disclosure and Compensation Agreement, must be completed and signed by the SBA lender, the applicant and the agent whenever an agent is paid by the applicant or the lender, with a separate form for each agent.
Form: SBA Form 159, Fee Disclosure and Compensation Agreement, for 7(a) and 504 loans.
Who signs: the SBA lender, the applicant and the agent, on a separate form for each agent.
Paid by both: the agent may not be compensated by both the applicant and the SBA lender for the same service.
Itemization: required when the aggregate compensation for all fees charged by the same agent exceeds $2,500, with a detailed explanation of the services performed.
Your choice: the SBA lender must inform the applicant in writing that the applicant is not required to employ an agent.
SBA's Standard Operating Procedure 50 10, version 8, effective June 1, 2025, adds that a referral agent "may be employed and compensated by either an Applicant or a Lender, but not both," and it sets limits on what an agent may charge an applicant. Ask the broker for a draft of the Form 159 they expect to sign, which agent type they will check (packager, referral agent or broker, or consultant), and who pays each line.
What should a good broker tell you it will not do?
A broker worth hiring will tell you plainly what it cannot promise: it cannot guarantee approval, a rate, or a closing, because the lender makes every credit decision, and it should not send your file to a lender you have not approved or take compensation it has not disclosed to you in writing.
Treat a promised approval or a guaranteed rate before any lender has underwritten the property as a reason to end the call; no intermediary controls a lender's credit committee. Ask, too, what the broker will not do with your information: whether it shares your file with anyone other than the lenders on your approved list, and whether it will ever change a figure in your package without your sign-off.
Which questions belong on your broker interview checklist?
Use the checklist below on the first call with every broker you interview, asking each firm the same questions in the same order, because identical questions produce answers you can compare line by line, and a broker who will not put an answer in writing has told you something before you sign.
Table: Commercial mortgage broker interview checklist
| Question | Why it matters | Good answer looks like |
|---|---|---|
| How is your fee calculated, and when is each part due? | Money due before a lender issues terms is spent even if the deal dies | Every fee, its trigger and its due date in one signed agreement |
| Who pays you: me, the lender, or both? | Regulation Z's ban on two-sided pay covers consumer loans secured by a dwelling, not business-purpose credit | One named payer for each service, in writing |
| Will any lender pay you anything on my loan? | Lender-paid compensation can be tied to the rate or fees you accept | "No," or the amount and its form, in the engagement letter |
| Where will your fee be written down? | A fee that never reaches the closing statement is hard to check | Its own line in the engagement letter and on the closing statement |
| Which lender types will you approach, and why? | Appetite shifts by type: MBA reported Q2 2026 CMBS loans up 68% and life company loans down 27% year over year | Named lender types, with a fit reason for each |
| Do I approve each lender before my file goes out? | The submission list is what any tail clause should be measured against | A written list you sign off on before anything is sent |
| Who reviews my file, and who negotiates? | Weak spots a lender finds first cost you time and leverage | Named people, the checks they run and the terms they will push on |
| How will you present competing quotes? | A quote without its index and date cannot be checked on the same basis as the others | Side by side: index, spread, index date, fees, recourse and prepayment |
| Is the engagement exclusive, and is there a tail? | These clauses decide what changing course costs | A fixed term, named carve-outs and a tail limited to lenders you approved |
| What do I owe if no loan closes? | This is the price of a process that fails | A dollar answer for each scenario, with third-party costs listed separately |
| On an SBA loan, what will your Form 159 say? | SBA requires a signed Form 159 for each paid agent | Agent type, each fee and who pays it, shown before you sign |
| What will you not do? | No broker controls a lender's credit decision | No promised approval or rate, no undisclosed pay, no lender contact without your sign-off |
Read the answers as a set: a precise fee answer does not make up for a vague answer on lender types, and a long lender list does not make up for a fee you cannot check.
How do you get lenders competing for your commercial mortgage?
You get lenders competing for a commercial mortgage by giving one broker a complete file and holding it to the checklist above: named lender types with a reason for each, your approval before any lender sees the file, every quote laid out side by side, and every dollar of the broker's pay stated in writing before submission.
YieldStack is one route, labelled here as exactly that.
Role: YieldStack is a commercial mortgage brokerage, not a lender.
Cost: It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing.
Credit decisions: Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
Put the checklist to YieldStack the way you would to any broker, then submit your deal if the answers hold up.
The bottom line
Hire the broker whose answers you can check: how and when it is paid, who pays and whether any lender does, where the fee is written down, which lender types see your file and why, who reviews and who negotiates, what the exclusivity and tail terms say, and what you owe if nothing closes. On an SBA loan, ask what the Form 159 will say. Get every answer in writing; on a business-purpose loan, Regulation Z will not ask for you.
