Prudent buyers purchase based on their emotions, not yours. Don't listen to what your neighbors tell you is the fair market value for your home. Other homes in your neighborhood may not be as similar as you think. Also the terms accepted by both the buyer and seller greatly affect the sale price. You'll help sell the competition.
Most buyers are competitive shoppers.
Your home will stay on the market a long time. If you don't sell them then, it takes approximately three months to replace them with an equal number of newcomers. You'll lose market interest and qualified buyers. Serious buyers use the value, quality and price of similar properties as deciding factors. A negative impression is created.
