Here are six reasons properties linger on the market:

• Lousy pictures on the Web.
• Priced too high for the neighborhood.
• Blah interior; ho-hum landscaping.
• Little online marketing and hard-to-find MLS listings.
• Low commissions. Practitioners make sure their customers see properties that offer a payoff.
• Miserable maintenance, including ceiling stains, leaky faucets, and ancient furnaces.
