I am not familiar with Maine, however I just had a client locate to California from Maine. I would recommend you talk with a local agent who is familiar with your area and able to look at your home, your equity and give you an analysis specific to you. If you don't have an agent, drop me a note and I'll find one for you.
Here in California often seller's believe Spring is the best. I like February because it is the first month after the holidays when buyers are starting to think about buying, yet inventory is still low, which is less competition for sellers.
