If you want to sell your home fast, and for the most money possible, price is an important consideration. One of the most common fallacies that I see sellers make is to list their home a little bit higher to leave room for negotiation, and that's usually a mistake.
Let me walk you through an example of how that could be possible. Say, you and your REALTOR, based on past sales and local competition determine that the price for your property should be $139,900. So instead of listing the property for $139,900, you leave room for negotiation and list the property at $144,900 instead.
What I've seen happen is the $139,900 property, since it's priced right, and it's priced right under the $140k mark, is able to pull in a few more buyers and actually sells within a week, for list price or above. The property priced at $144,900 actually sits on the market for 60 to 90 days and ends up selling for $135,000.
Sometimes pricing your property a bit lower will actually end up netting you a higher amount.
