I'd do 2 things.
One of course is to price the house aggresively for sale, after making sure it is clean, uncluttered, painted etc.
Number 2 is make sure the Buyers Broker gets a solid commission, like 3%
Too often I see 2% to buyers broker on the MLS. With the glut of houses on the market, why show a 2% listing? Most give 2.5% to the B.B. If you want maximum showings, up it to 3%!
