In addition to what others said regarding associations and the dues, you need to understand what a co-op (cooperative) is because 2615 Park is not a condominium, it is a cooperative. Mike Kelcher did a great job explaining what condominiums are, which are very similar to cooperatives. Kristin Long is also right that taxes are included in the dues for 2615 Park, which is never the case for condos.
Cooperatives are like condominiums except you could say the ownership structure is flipped. They still have board members, voting rights, and share costs but instead of owning a unit and having rights/membership of the association like a condo, you own a share in a corporation and are given the rights to a unit. For this reason, traditional financing (i.e. 5-10-20% down conventional loans, FHA loans, VA loans) is not possible since there is no real estate to secure the financing. Cooperatives maintain a relationship with usually one or two banks who continually review the cooperatives financials and offer financing to new members. It's typically one of the few large cooperative lenders (e.g. www.ncdf.coop) or a local credit union. For 2615 Park, loans are offered through South Metro Federal Credit Union (contact is Dean Davidson, 952-445-0888 x33).
Since you own a share in the co-op's corporation, the monthly dues include real estate taxes that are assessed on the building. Condominiums are assessed real estate taxes as individual units since they are each individual pieces of real estate.
