To that end, it may be a good idea to ask your agent to create a video tour of your home as part of their marketing process. Many Real Estate websites allow agents to upload video files to listings in addition to photos.
Watching a video tour will allow potential buyers to get a sense for the layout of your home before they see it in person. Ultimately, it will help give them a better idea of whether or not your home could be a good fit for them.
On your end, it will also help to limit the amount of traffic going through your home to only those buyers who have serious interest in your property.
