Typically, photos of the exterior go first then move inside the house. Make sure the rooms that are your "stand out" rooms go at the front of the sequence. Like, you may want to show pics of the kitchen first.
Pro Tip: Keep all of the photos of a room or space together and move from one floor to the next so potential buyers can get a feeling of the layout.
Make sure to put the best hero pic up front. We use these photos for advertising your home!
