Seller's agents are taught to sell in house listings First.
I was reading in Broker Agent Professional Premium Real Estate Success Information
In the section "Ten Tips from Ten Experts", "Industry icon Floyd Wickman"
advising Real Estate Agents wrote in Tip #1:
"...Next get all buyers and lookers into the office to be qualified, and sell them
on the benefits of the office like you never have before.
"Last, sell in-house listings first."
Emphasis is mine but this was Mr. Wickmans final advise to seller's agents.
I don't like being sold, do you?
As an Exclusive Buyer Agent, I nor anyone in my company lists property, so there is never the temptation or (as you read above) the deliberate attemp to stear you toward more profitable lisitings.
