When your home sells faster, you save carrying costs which include mortgage payments, taxes, insurance, and maintenance.
A quicker sale create less inconvenience to you. If you have moved before, you know the energy it takes to prepare for a showing: keeping the home clean, arranging for pets, children, and altering your lifestyle.
Proper pricing creates less demands on you, by helping your home sell faster.
At market value your home will gain exposure to more prospects who can afford the price.
Sellers who list at that high price are looking for that one buyer who will pay it. Sellers often do not realize that they have discouraged many potential buyers who could have afforded the home.
The final sales price is probably one that will be affordable by more purchasers.
Sellers often accept a much lower price at much later date since that one buyer willing to pay the higher price never comes, costing you more in time and carrying costs.
The three mayor things that affect a sale are location, condition, and price. You cannot control the Location, but you do control the condition and the price.
