According to the article, the owner of the place went bankrupt and JWs stepped in to buy the place for 2,7 million Swiss Francs (2,8 million US dollars), which is 2 million francs (2,1 million US dollars) less than its actual value on real estate market.
The total expense for the project (purchasing and remodeling) will be 5,5 million Swiss Francs (5,7 million US dollars).
