The short answer: Watch for a broker who won't share financials or tax returns after an NDA, uses high-pressure urgency tactics, presents unrealistic projections or inflated add-backs, refuses to co-broke the listing, claims to represent both buyer and seller, can't produce verifiable references, or hands you a thin, sloppy CIM. None of these alone proves bad faith, but two or more together are a reason to slow down, verify everything yourself, and lean on independent valuation. Credentials like IBBA membership are a positive sign, not a guarantee. Score the listing objectively with the Deal Scorer before you commit more time.
Won't share financials after the NDA
Once you've signed a non-disclosure agreement, a legitimate broker should be willing to share tax returns, profit and loss statements, and other real financial documents on a reasonable timeline. If a broker keeps stalling, offers only a cleaned-up summary, or gets vague every time you ask for the underlying tax returns, that is a serious warning sign about what the numbers will show once you finally see them.
If the numbers are good, nobody stalls on showing you the numbers.
High-pressure and urgency tactics
Phrases like "there are three other offers coming in today" or "you need to decide by tomorrow" are sometimes true, but they're also a classic pressure tactic used to stop you from doing real diligence. A good deal can survive a buyer taking a reasonable amount of time to verify numbers. Treat manufactured urgency as a reason to slow down, not speed up.
Unrealistic projections and inflated add-backs
Add-backs, expenses added back to cash flow because they're personal or one-time, are normal and legitimate when documented. A red flag is when add-backs are vague, unsupported by receipts, or so large they turn a mediocre business into an apparently great one. Same goes for hockey-stick growth projections with no clear driver behind them. Verify every add-back yourself during diligence; don't take the CIM's word for it.
Refusing to co-broke and dual agency
Co-broking means another broker can bring their own buyer to the listing and split the commission. A broker who refuses to co-broke may be trying to control both sides of the transaction to capture a bigger fee, which can reduce the pool of buyers and the pressure to run a fair process.
Dual agency, where the same broker claims to represent both the buyer and the seller on one deal, is its own conflict of interest. One person cannot fully advocate for two parties negotiating against each other. If you're offered a dual-agency arrangement, get your own independent advisor before you rely on anything the broker tells you.
Red flags at a glance
| Red flag | Why it matters | What to do |
|---|---|---|
| Won't share financials post-NDA | Often means the real numbers are worse than presented | Request tax returns directly; walk if refused repeatedly |
| High-pressure urgency | Designed to short-circuit your diligence | Slow down; a real deal survives reasonable diligence time |
| Inflated add-backs / projections | Overstates true cash flow and value | Verify every add-back against receipts and documentation |
| Refuses to co-broke | May reduce buyer competition and fair process | Ask why directly; compare to other listings from the same broker |
| Dual agency | One broker can't fully represent both sides | Get your own independent advisor before relying on their advice |
| No verifiable references | No track record to confirm reliability | Ask for past buyer or seller references and actually call them |
| Thin or sloppy CIM | Signals low effort or a rushed, incomplete listing | Request a complete packet before investing more time |
| Evasive about reason for sale | May be hiding a declining business or personal problem | Ask directly and cross-check the answer against the financials |
| Large upfront retainer, no accountability | Removes the broker's incentive to actually perform | Prefer success-based fee structures; scrutinize any retainer request |
Thin CIMs and unverifiable references
A confidential information memorandum (CIM) that's a few thin pages with no real detail on operations, customer concentration, or staffing suggests either a rushed broker or a seller who hasn't done the work to prepare for sale. Ask for a complete packet before you invest more of your time.
Also ask for references from past buyers or sellers the broker has worked with, and actually call them. A broker with a real track record will have people willing to vouch for them. One who can't produce any is worth extra scrutiny.
Credentials help, but aren't proof
IBBA (International Business Brokers Association) membership and similar credentials signal training and a code of ethics, which is a genuine positive. It is not a guarantee, verify references and watch for the other red flags on this page regardless of credentials.
Large upfront retainers with no accountability
Most listing broker fees are success-based, paid only at closing. Be cautious of any arrangement, usually from a buy-side advisor rather than a listing broker, that asks for a large non-refundable retainer upfront with no clear deliverables or accountability attached. It removes the financial incentive to actually perform.
I've walked away from more than one deal not because the business was bad, but because the broker got cagey the moment I asked a direct question, that reaction alone told me more than the CIM did.
Score the deal, not the pitch
Run any listing through an objective checklist before you get emotionally attached to it.
Frequently asked questions
Refusing to share financials or tax returns after an NDA, high-pressure urgency tactics, unrealistic projections or inflated add-backs, refusing to co-broke, and evasiveness about why the seller is really selling.
Co-broking lets another broker bring their own buyer to the listing for a shared commission. Refusing to co-broke may mean the broker is trying to control both sides of the deal for a bigger fee.
Dual agency, where one broker claims to represent both sides, is a real conflict of interest. Treat it with caution and get your own independent advice rather than relying solely on that broker.
No. IBBA membership is a positive signal of professionalism and training, but not a guarantee. Still verify references and watch for the other red flags independently.
