A little known fact is that some "teams" of agents actually work together but report all sales under a single agent's license number. This leads to the conclusion that that particular agent has a lot of listings or sells a lot of homes, but it is actually the team of several agents that are contributing all their sales to the team effort. If you look at the individual team member's statistics you might find zero sales for all but one. Any of us would be hard pressed to find who was actually selling for some agents with extremely high volume. So, add this tidbit to your arsenal of knowledge.
To expand on this concept of team selling you might find out that one agent is reporting an average of a sale every week. While that is possible (my wife actually did that a few years back all by herself), the reality is that a typical sale consumes at least 40 hours but some consume well over 100 hours. So, if a team is working on 20 prospects at any one time and 4 result in a sale every month, you can understand why the team lead's sales volume appears so high and efficient. And, you probably will ask yourself how they're able to work 400 hours a month and still do all their compliance activities and marketing, too.
NTREIS (our MLS) does have data indicating who sold what when, but take any report with a grain of salt. If you hear "I sell a home every four days", you might ask how big the team is and is that claim accurate for the current year.
Truly Rob's comment strikes at the right point. You should select on Knowledge that the Realtor has and their Ability to explain things to you, and your Comfort level with their approach. Don't discount statistics, but remember Disraeli's opinion about the 3 kinds of lies: lies, damned lies, and statistics. Ask your candidate agent about their experience and how many years they've been working and how much training they've taken to keep up to date. You can also investigate those things at the TREC site.
Sometimes we forget this is a people business, and your relationship with your individual agent has a lot to do with success or not. If you overprice the home or do not listen to your agent on staging advice, or feedback from other agents showing the property, it won't matter if the person sells a home every other day. As stated below the listing agent gets all the credit, even though the majority of the time there are a selling side representing you, and a buying side representing the buyer. Although the same agent could both list and sell your home, it is rare that happens.
Best of luck to you,
The only way to get a report like this is from a Realtor who can provide MLS data for you. Bruce is right, you need to decide if you want to know about "listings" or actual "closed sales". Keep in mind that you will have listing agents and buyers agents for every home sold (many times they are different agents, but on occasion they are the same person handling both sides of a transaction).
