For licensed agents in Arizona and Colorado

What do I say when a Marketplace message asks about a listing that is not mine?

Say whose listing it is, answer what is public, and keep the money and motivation questions until the written paperwork is in place. A first message is a conversation, not yet a client.

Your post already says you are marketing the home on behalf of the brokerage that holds it. The message that comes back usually reads like this: is it still available, what is the lowest price, can I see it. Here is how to answer in a way that stays true to the post.

Say whose listing it is, first

Repeat the post's own line in plain words. Colorado rule 6.10.F.1 asks that a broker passing along another broker's advertising discloses the owner's brokerage firm in a conspicuous manner, and in Arizona rule R4-28-502, subsection F asks for a disclosure in the advertisement itself that the properties featured are not representative of your own transaction history. A reply that restates it keeps you consistent with your post.

Thanks for asking. So it is clear, this home is listed by another brokerage and I am marketing it with their written permission, so I am not the listing agent. I can answer general questions about it from the listing record. What area and price range are you looking in?

Answer what is public, send the rest to the listing side

Facts that are on the listing record are fine to share, and Colorado rule 6.10.C expects what you advertise to be accurate, so stay with the record. Price negotiation, showing access and anything the seller decides belong to the listing side. Say that plainly and do not guess.

Colorado: when the written disclosure comes in

Colorado rule 6.5 separates two stages. Written brokerage relationship disclosures are due before you elicit or discuss confidential information from a consumer. The rule says preliminary conversations about price range, location and property styles, and responding to general factual questions about advertised properties, are not that stage. So an opening exchange about the home and the area is fine, and the moment a buyer starts telling you about their finances or how badly they need to move, the written disclosure from your brokerage comes first.

Arizona has its own brokerage disclosure rules and forms through the Department of Real Estate. Ask your broker which form goes first.

The written buyer agreement before a tour

Since August 17, 2024, the National Association of Realtors practice changes have required agents who use a local association's listing service to sign a written agreement with a buyer before touring a home together, in person or live virtual. Colorado Realtors and the Central Arizona Association of Realtors both describe it. The agreement has to state the compensation specifically, not open ended, with a conspicuous statement that fees are not set by law and are fully negotiable. It applies to association members, so check your own association's rule and use the form your brokerage gives you.

Treat that as the line between chatting and working with a buyer. Messages can start in Marketplace. The tour waits for the signature.

Keep a record

Save the thread. If the owner or the listing brokerage later asks a question about what was said, a dated message trail answers it. If anyone asks you to stop marketing the home, stop and tell your broker.

Where the software fits

The app builds and schedules the posts. You answer your own messages, from your own account. It does not reply for you and it does not send or sign agreements. That conversation is yours and your broker's.

Common questions

Can I say I can show a home that another brokerage holds?

The listing side sets how showings work, so say that and ask them. Before touring a home with a buyer, the written buyer agreement described above applies to association members.

Do I need a signed agreement before I answer a Marketplace message?

Not to answer general factual questions about an advertised home. Colorado rule 6.5 treats that as outside the written disclosure stage. A written agreement is due before you tour a home with a buyer, if the association rule applies to you.

What if the buyer asks me to negotiate the price?

Price negotiation runs through the listing side. Tell the buyer who to talk to and do not guess at what the seller will accept.

Does Listing AutomatEr answer Marketplace messages?
