Co-ops make each leaseholder responsible for the interior of your own unit, the monthly unit payment, as well as monthly utilities, if not included in the fee, and any extra costs assessed resulting in any unit payment defaults by other shareholders. This fee generally includes real estate taxes and payment of the underlying co-op loan. Part of this payment is tax deductible.
Condo owners pay a monthly fee to maintain the common areas to the elected condominium association, which is responsible for upholding the conditions, covenants and restrictions (CC&Rs). Under the CC&Rs, the association can assess extra fees for special improvements or repairs to the common areas. This fee is generally not tax deductible.
