In the US, there's a legal definition of real estate: "property consisting of land and the buildings on it, along with its natural resources such as crops, minerals, or water; immovable property of this nature; an interest vested in this (also) an item of real property; (more generally) buildings or housing in general. Also: the business of real estate; the profession of buying, selling, or renting land, buildings or housing."

But if you're selling or buying, you know what it is you're dealing with.... maybe! There are a lot of real estate sites, but how can you tell what a place looks like from a few photos? How can you show off your home for sale in just the right light? Video is the answer.
