I assume your market is like mine. 90% of the time another Realtor shows the buyer the home they buy. So review your Realtors market plan. It is important you understand how it works and why your Realtor does what he does.
Buyers are looking fore value. So Buyer's Realtors are looking for listings that scream value. Have other homes, like yours, SOLD since yours came on the market?
One of your Realtor's jobs is to keep you informed of changes in the market, so you know what your competition is up to
I hope that helps!
