I had a buyer and seller who'd agreed on everything. Price, closing date, even which appliances were staying. We were two weeks out, smooth sailing. Then the buyer's agent calls me and casually mentions her client wants to do a "final walkthrough" early. Fine, whatever. Except during this walkthrough, the buyer notices the seller had taken down a decorative mirror in the hallway. Not a fixture. A mirror she'd hung with a Command strip. The buyer loses it. Says it leaves a "psychological hole" in the space and demands $3,000 off the price to "restore the energy of the home." My seller, who is already stressed about her move, fires back that she'll give them exactly nothing and maybe they should buy some sage instead. Three days of heated negotiations over a fifteen-dollar mirror from HomeGoods. The buyer ultimately walked because, and I quote, "the seller's energy is now embedded in the walls." I had to explain to my broker why a done deal evaporated over wall decor and vibes. Poured myself a very large glass of wine that night.
