I was referring to common sense :) In real estate brokers typically get around 2.5%, so even if they find a buyer that is ready to pay 100K more, it's only $2500 extra (so probably $1500 after taxes). It's not a lot of money esp if they can invest that time and energy in parallelizing other deals. Time is of the essence in such transactions. And then of course a Buyer side agent's incentives are aligned exactly opposite to the buyer, but even if they would want to push for an early transaction above anything else.
