"Do I look fat in these pants?"
"No dear, your backside isn't the size of a Buick LeSabre and the fact that you're wearing white won't accentuate your ripples and bulging thunder thighs and hippo hips. Not at all cupcake."
That's never going to happen, is it? The boyfriend or husband is almost always going to try and be polite.
What is showing feedback? When I get through showing a house I typically get an automated email asking for my "honest" feedback. I usually provide just that. My honest feedback. I'm not trying to make friends, hook-up for a date or kiss my wife's rear end. I'm actually trying to HELP the listing agent and seller. I want every home in my market to sell. The more homes that sell, the happier I am. Business trickles around.
What bothers me is when sellers or Listing Agents get upset about my candid feedback. I might suggest that he home is overpriced. And I'll usually type it like this: "Home is overpriced for it's current condition, the carpet is filled with dog hair and fence is falling apart." That might sound stern, but it's factual information. The price comment is subjective, but it's me and my buyer's opinion. If you ask for opinions you should expect to hear all sorts of comments that you may not agree with.
There is no reason to become defensive, combative or dramatic because a showing agent tells it like it is.
If your house is gross, be prepared to be reminded about it.
If your house smells funky from cooking, be prepared to be told about it.
If your lawn looks like a jungle, expect negative comments.
If your house has loose pets, expect agents to either not show it or complain about it.
If your overzealous Seller is all in the way asking questions, expect the Buyer's Agent to be quick to point it out.
Polite feedback doesn't help anyone. Well, maybe with your spouse it does.
