Make sure that the outside is spruced up. Cracks are patched, fresh paint, flowers/shrubs planted and lawn mowed and edged. It doesn’t have to be fancy but neat and clean and in good repair. Make sure the doors and windows and doors are caulked. Also you want to be sure that your doors and locks work well (remember they’re going to immediately know if the front door lock doesn’t work when the Realtor can’t open the door). You want buyers to drive up and see that they can move right in and not have to do a thing. If the house needs a roof then by all means go ahead and get it done, it makes buyers so much more comfortable.
