Spring has officially sprung, but the spring housing market started about a month ago, according to most real estate agents. With the supply of homes for sale not even close to demand, competition has been fierce, and that is changing the rules of the real estate road. Yes, it's a seller's market, but not all homes sell quickly, especially if they're not priced right and if the timing isn't right.

When is the best time to sell? That depends on whom you ask.
