When lenders agree to do a short sale in real estate, it means the lender is accepting less than the total amount due. Not all lenders will accept short sales or discounted payoffs, especially if it would make more financial sense to foreclose; moreover, not all sellers nor all properties qualify for short sales.
Here is an outline of the process: http://en.wikipedia.org/wiki/Short_sale_(real_estate)
The realtor gets paid - it just lessens the amount the bank recovers.
