I have sinus problems and am not particularly good at smelling, so I was glad to have an agent tell me that the sewer had backed up into the kitchen sink in my vacant condo listing!
Generally - and with no offense meant to my fellow agents - I don't care what you think if you're not going to write an offer. If it was something that we could correct, you'd write an offer, subject to correcting that, right? If you didn't like that the roof was old or the water heater was old or your buyer hated the carpet . . . you'd write it up, right?
But the floor plan doesn't work for your buyer, they don't like that the yard is too big/small, they don't like the neighbor's house, they wanted a north-facing kitchen . . . I don't care. I suppose if you were to tell me something about the house I don't know . . . but then again, if I can't do anything about it, what does it matter?
One thing that has never happened in my career: I've called an agent, looking for feedback, and they said, "Mack - so glad you called! My guys wanted to write an offer on your house, but we lost the listing sheet and couldn't figure out which one it was!"
I can tell you, in advance, I have no useful feedback for you. Either I was previewing for a buyer or a CMA, or my buyer doesn't like your listing enough to make an offer. If they liked the house, but felt is was overpriced, I would urge them to write an offer to test your response.
