The most Important factor to consider when selling a house is the homes price tag: how much your house is worth. You don't want to overprice the house, because you will lose the freshness of the home's appeal after the first few weeks of showing it. Also do not worry about pricing the home to low, for homes priced below Market Value- the price of which a bonafide seller is willing to sell, and an able and willing buyer is able to buy will often recieve multiple offers which then drives the price up to market. Pricing is all about supply and demand.
