I took advantage of the situation when I last sold my house. I knew what the house would likely sell for, and told my agent that I’d pay him his 3% seller commission for that price, but for anything above that amount, I’d split the incremental amount with him (I believe I proposed 40/60). Ultimately I made an additional $10k.
