I tend to agree with Karen's reply. I would check the pictures first, and then if interested will check on the video expecting to get the most of it, tour thru the condo highlights, and I don't really know what else, probably depends on the condo itself.
hope this helps,
I'm an agent and one Windermere class I took recently showed statistics that buyers tend to prefer pictures to videos. Most won't or can't abide the time it takes to watch a video. With utube now those stats may not be current and may just be relying on data from videos on listings.
