I have been using video walk-through tours of my listings for 7 years.
Only 2% of agents nationwide use Video for marketing. Home Buyers have a higher view rate of listings with Video. Video is not a slideshow, don’t let another agent tell you otherwise. Youtube currently sets the default view to low resolution. Click the little gear icon (settings) in the lower right hand portion of the video window after the video begins to play to switch to HD quality. If you are on a mobile device, to conserve your data plan and load speed you do not need to change the setting.
