If you’ve been in real estate for long, you’ve had dissatisfied clients. You’ve had transactions with glitches that were difficult. You may have even made some mistakes.
You’ve also had some clients who couldn’t be pleased no matter what you did, but this isn’t about them.
This is about the ones who had a genuine complaint. Once the transaction was closed, you gave a sigh of relief and tried not to think about it. But that’s the wrong approach.
A better idea is to call them, or send them a feedback request and let them get their frustrations off their chest. Then ask what you can do to make it up to them. Or ask what you could have done differently. Ask what would have made things easier for them.
In other words, ask for their advice in making your service even better.
They’ll see that you are genuinely interested in doing your best, and they’ll very probably call you the next time they need an agent.
