Here is a great video that shows what is possible when you use a drone for filming. As the author states:
We have been using the DJI Phantom 3 on all our most recent luxury villa rentals on the island of St. Martin. This one features a villa we call Sandyline and we couldn’t make anything nearly this epic without it. This is the best way to get a real understanding of large properties so our clients know exactly what they are renting.
