What does fiduciary mean?
A fiduciary is someone legally required to put your interests ahead of their own. Not just 'be honest,' but actually team up with you. It's the difference between a store clerk and your best friend shopping with you: the clerk can't lie about the shoes, but your best friend is duty-bound to whisper that they're overpriced and the other store has them for less.
When an agent represents you, they owe you fiduciary duties: loyalty, confidentiality, full disclosure, obedience to your lawful instructions, and accounting for your money. That duty, not just the labor, is what the commission actually buys. And it's why 'whose side is this person on?' is the single most important question to answer before sharing your bottom line with anyone in a transaction.
What is dual agency?
Dual agency is when one agent (or one brokerage) represents both the buyer and the seller in the same sale. Imagine one lawyer working for both teams in the same case: allowed here only because everyone signs off, but obviously that lawyer can't fight all-out for either side.
Arizona allows it with written consent from both parties, using a form that spells out the limits: the agent can't tell the buyer the seller's bottom line, can't tell the seller the buyer's top number, and can't push hard for either side. The honest framing: a dual agent becomes a skilled referee rather than your champion. Some deals suit that fine. Just know that when you sign the consent, you're trading your champion for a referee, and the referee is collecting both sides of the commission.
What is an unrepresented buyer?
An unrepresented buyer is someone buying a home without their own agent: reading listings, touring, and making offers directly. Like traveling without a tour guide, it's completely allowed, often cheaper, and it means you read the map yourself.
Since the 2024 rule changes, buyers working with an agent must sign a written agreement first, which made going without one a more visible, deliberate choice. An unrepresented buyer in Arizona still gets every legal protection in the contract: the inspection period, the appraisal contingency, the required disclosures. What they don't get is fiduciary advice, so the homework transfers to them: comps, inspections, and reading before signing. On ClozeEZ, buyers can tour and offer directly without signing anything first. That's the model, and this glossary is part of making it work.
What is an unrepresented seller?
An unrepresented seller, usually called FSBO ('for sale by owner'), sells their home without hiring a listing agent, handling pricing, marketing, showings, and negotiation themselves. It's the yard-sale-versus-consignment-shop choice: run the sale yourself and keep everything, or hand it to a shop that does the work and takes a cut.
It's fully legal in Arizona. The seller still owes buyers honest disclosures (the SPDS form), still uses the standard contract, and still closes through a licensed title company. The professional safety rails don't disappear, only the commission does. On a $448,000 Arizona home, the traditional listing-side cut is roughly $13,400. The honest trade: you keep that, and you do the work.

The MLS (Multiple Listing Service) is the giant shared database where licensed agents post homes for sale, and the pipe that feeds most listings you see on Zillow, Realtor.com, and Redfin. Think of it as the school's official bulletin board: every classroom's flyers get posted there, and the school newspaper reprints whatever's on the board.
The catch: only licensed brokers can post to it. A by-owner seller can't enter it directly. The routes in are hiring an agent, or paying an Arizona 'flat-fee MLS' broker a few hundred dollars to post it while you handle everything else. Worth knowing: you can post to Zillow yourself for free without the MLS, though Zillow files owner listings under a separate tab from agent listings.
