For those readers that may not be familiar with coops and how they differ from condos (far enough off topic that I won't get deep into it on this answer): you may notice as a rule of thumb that the "maintenance charges" on coop are higher than the "common charges" on a condo (again, generally speaking). This is because with a condo, you pay your property taxes and basic pro rata insurance separately (just like you do with a house); whereas, they are bundled into the maintenance on a coop.
Sometimes people get confused about this, in part because many websites do not differentiate coops well. In fact, coops are rather rare across the country, although they are quite common in NYC. Many websites don't have fields for "common charges" versus "maintenance charges." Plenty require something be entered for taxes, even though that may not make a lot of sense - while completely omitting maintenance charges.
Hope this provides value. The web reference included is a 2 bedroom coop unit listed for sale in School District #26.
