Rules change so much that many agents find it difficult to stay on top of changes. Even our RPA is updated every few years. Things that were true decades ago are not true now. And generally the agents I deal with at larger brokerages are pretty much on the ball with the changes because their brokerages keep them informed. They discuss changes at office meetings, send out announcements via email and offer training. Sometimes I get identical reminders from my brokerage in different formats.
When I run across an agent who doesn't know something, it's generally the agent working at a smaller mom-and-pop brokerage. Which just means our association should do a better job. Like last month, an agent insisted that her buyer did not have to pay to fix a loan condition item. I had to quote the paragraph in the RPA that says loan conditions are negotiable and direct her attention to the AS IS clause, including the additional verbiage we had inserted concerning lack of repairs, before she backed off and got the item fixed.
Then there are the listing agents who feel their sellers should hire a bunch of inspectors to prepare reports without realizing the agents must send those reports to the buyers. They aren't doing their sellers any favors; in fact, if the reports are not required, the agents are probably harming their sellers. You can read more about all of this in my personal blog today at this link: Why Sacramento Sellers Inspections Are Unnecessary Today.
