It looks like to me from the website, they are fishing for a major investor so I am surmising that financing is an issue for the property owner. It started out as a 'condo for sale' project and trying to accomplish this through independent real estate agents is not a cohesive strategy. It is no wonder sales were not successful. That and the fact it is a struggle to sell condos anywhere in Calgary other than the suburbs.
I have never heard of building a property with the express purpose of marketing it as AirBnB. All I know is I would not be buying a condo in this building, to live in it, knowing that AirBnB was a component.
