Arizona guide for buyer agents

An Arizona buyer just messaged you about a home. What do the rules ask next?

We did not find an Arizona rule written for a Marketplace message, so a buyer’s first note meets the same duties as any other contact. Six of them sit between that note and a first showing, and here they are in the order they tend to come up.

Rule text from the 2026 Law Book of the Arizona Department of Real Estate and the Arizona Legislature, read November 1, 2026. Informational, not legal advice.

1. Say plainly who you are

The advertising rule, R4-28-502(C), says:

“A salesperson or broker shall not misrepresent the facts or create misleading or ambiguous impressions.”

The duties rule, R4-28-1101(A), adds that a licensee owes a fiduciary duty to the client and deals fairly with all other parties. As we read those two together, if the home is another agent’s listing that you market with permission, the person writing to you hears that in plain words. What to say when the message is about a listing that is not yours has wording to work from.

2. Find out whether they already have an agent

This one comes early because of R4-28-1102(A):

“Real estate licensees may not contact a principal represented by another licensee unless the principal’s Designated Broker, broker representative with delegated authority, and the licensee are unavailable for 24 hours.”

A buyer already under an exclusive agreement raises a second line. A.R.S. 32-2151.02(C) bars procuring another agreement from that buyer without their written acknowledgment that more agreements could expose them to substantial additional commissions.

3. Put any conflict in writing

R4-28-1101(E) asks for written notice to the other parties, before any binding agreement, of a present or prospective interest or conflict. Its list includes acting as a principal, a buyer or seller who is immediate family, and a financial interest beyond your compensation. R4-28-1101(B) separately asks for written disclosure of information you hold that materially or adversely affects the consideration to be paid, including a known adverse material fact about the property.

4. Settle the buyer agreement question

Arizona’s license statute does not require one:

“A real estate employment agreement is not required for a licensee to represent a party in a transaction.”

That is not the whole answer. The NAR settlement rule requires a written agreement with a buyer before touring a home for the agents it covers, and your brokerage may require one too. What an Arizona buyer agreement has to carry lists the four things the statute asks of any agreement you do use.

5. Hold written authorization before you open a door

R4-28-1101(J) lists what a licensee shall not do, and the first item is:

“Permit or facilitate access to or occupancy in a person’s real property without prior written authorization from the owner of the real property”

The rule does not say what form that takes for a home listed elsewhere. Your designated broker can say how your office treats showing instructions.

6. Know who is answering your inbox

If an assistant reads your messages, the Department’s advisory statement on unlicensed assistants is the page to know. It lists answering phones, forwarding calls and transcribing callers’ information among clerical tasks an assistant may do. Among the things an unlicensed assistant shall not do, it lists:

“Provide advice, pricing, or opinions of value to a consumer”

The statement does not mention messaging apps, and it is advisory only. The Arizona assistant page has the rest of the list. Your employing broker is the one the statement holds responsible for written policies here.

What this page does not settle

Whether a given reply is itself advertising under the rule, and at what point a person writing to you becomes a client. We did not find a Department answer to either. Ask your designated broker.

Common questions

Can I reply to an Arizona buyer who already has an agent?

The Department’s property negotiations rule says licensees may not contact a principal represented by another licensee unless that principal’s designated broker, a broker with delegated authority and the licensee are unavailable for 24 hours. A principal may waive or alter this in writing.

Do I need a signed buyer agreement before I answer an Arizona buyer’s message?

The license statute says an employment agreement is not required for a licensee to represent a party. The NAR settlement rule separately requires a written agreement before touring a home for the agents it covers, and your brokerage may require one too.

Can my assistant answer buyer messages in Arizona?

The Department’s advisory statement allows clerical tasks such as answering phones and forwarding calls, and says an unlicensed assistant shall not give advice, pricing or opinions of value to a consumer. It does not mention messaging apps, so ask your designated broker.

Does Listing AutomatEr answer buyer messages for me?

No. Buyers message you directly. The app posts the listings you have permission to market and leaves the conversation to you.

Where Listing AutomatEr fits

Listing AutomatEr is a desktop app for Mac and Windows that posts the listings you have permission to market to Facebook Marketplace on a schedule. By default it puts your name on the post as the agent marketing the home and credits the brokerage that holds the listing.

It does not obtain the permission for you, and it does not decide whether a post meets a rule. That stays with you and your broker.
