The first showing now happens on a screen. Before a buyer ever books a walkthrough, they have scrolled your listing, watched (or not watched) the video, and decided whether you look like the agent who takes the property seriously. A carousel of static photos reads as the bare minimum. A cinematic reel reads as a professional who will market their home the same way.
Here is the opening: almost every agent knows video works, and almost none of them actually ship it consistently. The ones who tried usually hired a videographer once, waited a week for the edit, and quietly gave up. That gap between what works and what agents actually do is the whole opportunity, and it is wide open right now.
This does not stay open forever. Every quarter more agents figure out that listing video is how you win the listing and the buyer. The agents who build the habit now are the ones sellers call first.
