Patrick's Quick Answer
Choose a full-time listing agent who can show you closed sales in your neighborhood over the last 12 months, defend their suggested price against those comps, and put their marketing plan and communication promises in writing. Verify the license is active on TREC's website, review the Information About Brokerage Services form you are entitled to at the first conversation, and compare two or three candidates before you sign the listing agreement. This is the seller-side version of the agent question; the buyer-side version is in the how to choose a REALTOR post, and it differs because the listing agent owes you fiduciary duties and negotiates on your behalf as the seller.
Choose a listing agent on evidence, not a handshake. Look for a full-time agent who has closed sales in your neighborhood and price range, can defend the price they suggest against those closed comps, and will write down how they market the home and how fast they respond. Then verify the license is active on TREC's website and read the Information About Brokerage Services form the agent must provide at your first substantive conversation. That combination, evidence plus paperwork, is what separates an agent who sells houses from one who just lists them. The focus here is what a seller must check before hiring; if you are buying instead, the buyer's version of the agent question covers the other side of the table.
The five things to look for, in order
Run every candidate through the same five checks. Full-time and local. Closed sales you can verify. Pricing math you can follow. A marketing plan in writing. And paperwork that proves who you are hiring. An agent who clears all five and communicates clearly is worth interviewing twice. An agent who cannot clear even two of them is a listing that never really got marketed.
Start with closed sales, not charm
The single most useful thing a listing agent can show you is their own closed sales in your neighborhood over the last 12 months, including how many of those they were the listing agent on. HomeLight's guidance for sellers is to interview at least two or three agents and favor a full-time agent with local experience and a real sales count in the area. Ask for two numbers: the average list-to-sale price ratio and the average days on market. List-to-sale tells you how close buyers paid to what was asked; days on market tells you whether the marketing actually landed. A full-time agent who has done this in your subdivision beats a brand name who has not. If you have not gathered the first numbers yet, the first-things-first seller post shows the order to run them in.
The price talk should start with closed comps
A comparative market analysis, or CMA, is how a listing price gets built: recently closed sales of comparable homes, adjusted for condition, lot, upgrades, and timing. Ask the agent to walk you through the comps, not just hand you a number. An agent who quotes a flattering price to win your business and quietly cuts it in six weeks is not doing you a favor, because the first week of an overpriced listing is the most expensive week of a listing. The right agent tells you what the home is worth as it sits today and which repairs would move that number. That pricing discipline matters more in a balanced market like San Antonio's, where the market decides the pace.
A marketing plan you can read
Professional photos are table stakes, so ask what comes after them. Zillow's seller guidance has you asking how the home will be marketed, and the honest answer covers the MLS within about a day of listing, the syndication network, video or a virtual tour where it fits, and what happens if there are no offers in the first two to three weeks. A listing agent who cannot describe the follow-up plan for a slow start has not thought past the sign. Get the plan in writing, or at least in an email you can re-read when the listing is quiet.
The Texas paperwork tells you who you are hiring
Two pieces of paper matter here. First, the Information About Brokerage Services form, TREC Form IABS 1-2, effective January 1, 2026. Texas law requires a license holder to provide it at your first substantive communication under Occupations Code Section 1101.558, and it spells out the brokerage relationship and the duties the agent owes you. Second, verify the license yourself on TREC's license holder search: the status must read Active and the expiration must be in the future, and a sales agent's record will name the sponsoring broker. Finally, a real estate commission in Texas cannot be recovered unless the agreement is in writing and signed, under Occupations Code Section 1101.806(c), so the listing agreement is the contract that actually matters. Commissions are negotiable, and the term of a Texas residential listing agreement is negotiable too, commonly about six months and capped at 24 months. TREC does not publish a residential listing agreement form; the one most agents use comes from the Texas Association of REALTORS. The timing post covers when to start this paperwork conversation.
What the San Antonio market adds
San Antonio Board of REALTORS data for September 2026 put the metro at about 88 days on market with roughly six months of inventory, and the median sale price around $302,000, down a bit from a year earlier. That is a balanced market: homes sell, but pricing and condition decide how long yours waits. Ask each candidate how they have priced homes in your area in the last six months and what happened to those listings. Local proof beats a generic promise every time. And because I hold both a Texas real estate license and a mortgage license, I can price the listing honestly and line up your next purchase financing from the same desk; the sell with Patrick page explains how the dual role works on the seller side.
Patriot Pro Tip: ask each candidate for the three most recent listings they closed in your actual school zone or subdivision, not the three they are proudest of. Then ask how often the seller heard from them and whether communication was weekly or silent until the next showing. Communication is the thing sellers complain about most, and it is fully in your control to check before you sign.
