I agree with the first comment, spring is usually the best time to list a home for sale. But that does not mean that other times of the year are not a viable option. You will find buyers throughout the year - though there are the fewest during the holidays.
Another consideration is when is the best time for YOU to sell your home? Do not forget to factor in your personal needs and the needs of your family. Buying and selling a home is one of the most stressful, and exciting, times of your life. Your timing is even more important than your buyer's timing.
