On Rent Kong is a place where renters can post the apartments or houses they have and people can come and find the rental they want. There's also a way for the two to communicate so they can each learn more about the other before making a deal.
Renters can add long descriptions of the rental property, photos and even an audio podcast so they can tell more about the property. Then perspective renters can search for a rental property by searching for specific features they're looking for. When they find a rental they're interested in they can see photos from the inside and out.
This is a fun new way that people can use the Internet to get what they want. In this case people can find a place to live that is exactly what they're looking for. Renters can find tenants for the places they have for rent. Everyone's happy.
