Currently if you have a youtube video link it is embedded in the listing page. Why can the same be for a 3D Tour link? Where it is prominently embedded and displayed on the listing page and just just a link over on the side? When people scan the listing page currently that 3D Tour link is not real noticeable. Since Zillow is promoting its 3D Tour feature I would say a 360 or 3D tour will be just as popular user experience as a 5 minute youtube video.
