More people have had difficulties selling their homes because they chose a Realtor who promised to get them the price they wanted, instead of choosing the Realtor they felt would do the best job.
Overpricing a home can be a very costly mistake, both in time and in net return. A correctly priced home sells fast, and for top dollar; an overpriced home typically sells after a longer period time for less.
The pricing of your home involves analyzing market data, intuition, and market awareness, (not necessarily in that order). It is in your best interest to leave the final pricing decision until after the listing agent has been decided upon.
