That was the commission and I think lamoneyguy is correct on the selling price. This X-boyfriend must have been out for more than just his home sold. Near the end of the show the seller was regretting that his X-girlfriend was the agent and was representing both parties. And the buyer stated that she thinks it was bad the agent was so emotionally involved with the seller.
I think if these shows even survive for 30 years, and we haven’t destroyed the earth by then, people will find all of these reality shows totally nuts. Or maybe, the direction TV is heading, there will be even more bizarre goings on and this stuff will be ho-hum. 40 million dollar fixer uppers on water front property in Nevada (since California finally fell into the ocean back in 2020).
