This is the listing for the show that appeared on Yahoo’s TV schedule page Sunday morning.
It could be that the house hunting in Coral Bay episode of House Hunters International will be broadcast Sunday night. Maybe.
However, HGTV’s own page of "Upcoming Episodes” doesn’t mention it. http://www.hgtv.com/house-hunters-international/show/index.html
What the heck. Set the DVR and check Monday morning.
