Real estate portals are virtual market places where private individuals (and in addition also brokers) can list their property FSBO. The website can therefore be seen as broker. The upload of one or more photos and a description of the home as well as the owners contact information must be possible. Pure rental websites as well as foreclosure offers are, however, excluded from this business model definition. As the focus of the website has to be on real estate, general portals, which also offer other services (e.g. job searches or universal search engines), do not fulfill the required criteria. Moreover, neither specializations in certain kinds of realty (such as land, office buildings, holiday domiciles or luxury houses) nor regional restraints (e.g. Alabama) fall under the definition. Excluded from the definition are furthermore directories and information guides.
