See I don't like the idea of the closed door because it is really awkward when your the only one there to see the house. YOu walk up wondering is this even open? Of course like someone else said, if you have good open house signage up they will know it is open. Like the storm door idea the best. Some people just feel uncomfortable walking up to a home that is completely closed and there isn't a sound around. I also don't like to bombard people at the door. Feels kinda like the used car salesman.
