I think it is more effective to offer a higher commission to the buyer's Realtor instead of a bonus. In the buyer's market we are experiencing now, one of the first things to go (if you are truly negotiating in your clients best interest) is the bonus to the buyer's agent. As the commission rate seems to be more "set in stone" to the clients it doesn't seem to be attacked as often and so therefore remains more of a true "bonus" to the buyer's realtor and therefore more of an incentive for them to push and show your home, if that is what your motive is. However, the key to selling a property in this market remains having your property truly marketed at the right price by a professional, full service, full time Realtor and company - mainly on the internet but you can't forget the other media forms entirely. After all, what good is your incentive if no one hears about it? As for incentives for medical professionals: if they are busy they may appreciate delivery of premade meals (just needing to be heated) for a certain amount of time from a company that specializes in this, or some other type of time conserving and money saving reward, possibly throw in a new freezer to store it in.
