This is a co-op, not a condo.
1. The association does not allow rentals.
2. Property taxes are incorporated into the monthly assessment and run $1,420/yr
3. The assessment is $792/month, which in addition to taxes (not typical for a condo), covers the typical condo-types of items (common area insurance, etc.) as well as, atypically, the electricity (so you have no separate electric bill.) Also, co-ops have the advantage of being able to get a mortgage to finance building projects instead of levying a special assessment, so a portion of the montly assessment may also be deductible as mortgage interest.
