Good listing agents call for feedback, usually within a day of my showing or previewing their listing, and I am happy to share my thoughts with them. But more and more often, they’ll ask how my guys liked their listing and then give me an argument about why my buyers are wrong.
In one case, my buyers thought the asking price for a particular condo was just way high, and the agent started to quote two-year-old comps.
One agent took umbrage when I told her my buyers loved her listing and the price was right, but they didn’t want to be in that location. She then tried to sell me on the neighborhood. Hello! I was sold on the neighborhood already, which is why I showed the house in the first place!
Another agent got sort of upset when my buyers bought a similar house on the same block. She started to trash the house they bought and ranting that hers was a much better buy - especially since her sellers would take less. So tell them to lower their price already!
The reason I get feedback from my colleagues is so I can share whatever they are saying with my sellers. When the source is someone other than me, it helps get the point across that their price might be too high, the litter box must be kept cleaner, or they have to get out of the house when it’s being shown. Whatever our colleagues are telling us, we need to hear it so that maybe our sellers will actually get the message when we give them updates.
And then there’s good feedback. When I hear about how much the buyers or agents loved to new kitchen counters, the totally compulsive house keeping or the price reduction, it helps me to reinforce whatever the sellers are doing right that is going to help get the place under contract.
Come to think of it, all feedback is good feedback!

I fully agree! I had an agent once ask me about a home and price,and when I shared it she went crazy on me! I asked why did she bother to ask Realtors questions if all you want to do is uses it as a sales pitch? BTW the overpriced EIFS home with the gaudy colors never did sell ans sat on the market for years! Too bad!
I so agree with you. But it is almost impossible to get Feedback from folks! I was very honest today; when I gave feedback and told the agent "my client would not past the front door; because we saw 4 big roaches run across the room!" Cant get much more honest than that!
Of course, the best feedback is an offer.
I do two things myself, 1) I use CSS as a showing service and let them gather the feedback which usually comes in the way of an e-mail (when the showing agents bother to respond) and 2) I tell my Sellers that if there wasn't an offer the buyers must not have wanted to buy the house.
