Ask any stager, real estate agent or designer and they will tell you that light matters. Generally more light is better. If you have a home to sell and can not afford to fix it up nice clean it, wash the windows and light the light shine in.
Remove heavy drapes and open the window blinds. The days are still too short to look at houses in the evening but that will change in a few weeks when daylight savings time starts.
Sometimes homebuyers are like moths. They are attracted to the light and they may not even realize that is why they love one house and like another.
