Paying a Broker MORE To Sell Your Home

We've written about this previously here but I saw another take on the issue here from BusinessWeek. From the piece...

Jim McCarty decided a year ago to give real estate agents an added incentive to guide buyers past the clutter of for-sale signs to his vacant four-bedroom house about 20 miles outside of Minneapolis. He agreed to pay his agent an 8% commission, which would be split (55%/45%) with the agent representing the buyer.

As long as you keep the listing time frame fairly short what's to lose??
