This happens in
new or recently built condo buildings because they are aggressively marketing to potential buyers. The buildings are, often, cheaply made, go overboard on costly amenities, and made to maximize ROI for the builders/developers. They lure in buyers with low fees. Then, once the building is full, the buyers and the condo board discover that the quality of a lot of the materials and building is subpar, the amenities now need expensive repairs, or a lot of the building's charm is a bandaid to cover clear cost cutting. To fix all of these issues, the condo boards, usually made up of residents in the building, vote and raise fees in order to repair or correct these issues. This practice can make the cost of owning a condo sky-rocket in a very short time.
There is also the nightmare of insurance problems for a building.
The recommended move, in NA at least, is to look for older buildings with less amenities and a history of consistent condo fees that they will gladly give to you in a report if requested, which allows the potential buyer to get a clearer idea of the potential cost of owning a condo over time.
