Broker-Dealer

A broker-dealer is a firm in the business of trading securities for others or itself; it must register with the SEC and join FINRA before it can sell you a DST.

The short answer

A broker-dealer is a firm in the business of effecting securities transactions for others (a broker) or buying and selling securities for its own account (a dealer), and it must register with the SEC under section 15 of the Securities Exchange Act and join FINRA before it can sell securities to the public. Because a DST interest is a security, the person who recommends and sells you one for a commission should be a registered representative of a broker-dealer. You can check both the firm and the individual on FINRA BrokerCheck.

The definition turns on being in the business, and registration follows from it.

Exchange Act section 3(a)(4) defines a broker as 'any person engaged in the business of effecting transactions in securities for the account of others,' and section 3(a)(5) defines a dealer as a person in the business of buying and selling securities for its own account. Section 15(a) makes it unlawful for a broker or dealer to use interstate commerce to effect or induce securities transactions unless registered, and section 15(b)(8) requires membership in a registered securities association, which is FINRA.

Individuals sell as associated persons of a member firm. FINRA Rule 2040 bars a member from paying commissions to a person who is not registered as a broker-dealer but would have to be because of those payments and the related activity.

On a hypothetical $1,000,000 DST purchase, the selling compensation comes out of your equity before the trust buys anything.

One REIT's Form 10-K for 2025 describes the terms of its DST program: a commission of up to 5.0% and a dealer-manager fee of up to 1.5% of gross equity raised, which the dealer manager may re-allow to participating broker-dealers. The same filing says program costs are substantially funded by the DST investors.

Hypothetical, using those ceilings: on $1,000,000 of exchange equity, a 5% commission is $50,000 and a 1.5% dealer-manager fee is $15,000, so $65,000 pays for distribution. The full stack is covered under offering load; run your own numbers with your CPA.

Regulation Best Interest requires the firm, before or at the recommendation, to disclose in writing that it is acting as a broker-dealer, the material fees and costs that apply, and the material conflicts of interest tied to the recommendation.

It bites in diligence and accountability: the broker-dealer is the party regulators expect to investigate the offering.

FINRA Regulatory Notice 23-08 says a member recommending a private placement should, at a minimum, reasonably investigate the issuer and management, business prospects, assets, claims made and intended use of proceeds. Form D Item 12 lists each sales compensation recipient by CRD number, so you can match the firm on the filing to the firm in your inbox.

BrokerCheck shows a representative's registration history, ten years of employment history, current licenses and disclosures of customer disputes and disciplinary events. Compare that with an adviser's role at advisor fees and conflicts for DSTs and is a DST a security and who can sell it.

Related questions

Is a broker-dealer the same as a real estate broker?

No. A real estate license covers selling property, while a DST interest is a security, so the seller must be registered under the Exchange Act and with FINRA. A real estate license on its own does not make someone a registered representative.

Can my qualified intermediary sell me a DST interest?

Only through a registered broker-dealer. The Exchange Act requires registration for anyone in the business of effecting securities transactions for others, and FINRA Rule 2040 stops members from paying commissions to unregistered persons who would need to register.

How is a broker-dealer different from an investment adviser?

A broker-dealer is generally paid per transaction and owes Regulation Best Interest on recommendations to retail customers, while a registered investment adviser is a fiduciary usually paid by the client. Many firms are both, so ask which role applies to your purchase.
