In addition to the commission? Is that what you mean?
He will receive a commission and also receive an extra $50k?
Or do you mean that the $50k is the commission?
When people deal with selling property, they usually pay a fixed percentage commission to the real estate agents involved.
An agent will give a good faith estimate to the seller to show how much money they will receive for a given selling price. If you want $500k from selling a house, then you have to make this estimate of costs and set your selling price accordingly.
