Selling Your House
If you price your property below market value, it will sell quickly, but you will lose money. If you price it above market value, it may sit unsold month after month. If it is priced far above market value, buyers will not even come to look at it.
An appraisal is the best tool to determine fair market value. Real estate agents often tell homeowners what they want to hear in the hope of a listing agreement, even when you plan to sell "By Owner." An appraisal is unbiased and is a much more thorough process than a Comparative Market Analysis (CMA) done by a Realtor.
