The best time to sell depends on when a house like yours might be most in-demand. For example, a big yard is a great feature in the summer, but might be a nuisance in the winter. Not to mention, you have to be able to show the house, so if you’re busy at home, it may not be ideal timing. Besides that, waiting for a particular value is never the right time. You might be waiting too long, or miss your timing altogether.
