Folks who list their property too high are either not motivated to sell, they have received uneducated and incorrect advice from someone, or both. I would offer you good luck but if it is overpriced, luck won't even help, because it won't appraise for the bank's purposes of making a loan.
Only if you want to sell. Listing a home and overpricing it in the hope that "someone will make an offer" is a bad strategy. When you go to the store you are attracted to items that look nice, but are a good value for the money. If the other homes priced like yours are in better locations, better condition, nicer finishes, larger etc, buyer's won't offer on yours.
You need to be priced based on two sets of comparables, the sold market for the most similar homes to yours and the active market you are competing with. By overpricing you have done your competition a great favor.
