Is zakat obligatory on a shared hotel room purchased in installments and managed by an operating company under an annual profit-distribution contract? If so, how is it to be paid? And is zakat obligatory on it after the contract ends if it is not rented out?

Zakat (definition) is obligatory on the rent of leased real estate if it reaches the nisab (definition) (minimum threshold) and a hawl (one lunar year) passes over it. The hawl begins from the date of the contract. Zakat becomes obligatory at the completion of the hawl from the contract date if the rent has reached the nisab. Its amount is a quarter of a tenth (2.5%). Any portion of the rent spent before the completion of the hawl is not subject to zakat. Zakat is not obligatory on the principal assets of real estate designated for lease. If the rent is a debt owed by a solvent person, its zakat becomes obligatory at the hawl. However, if it is owed by an insolvent or procrastinating debtor, there is no zakat on it until it is received. If the room is a partnership between two individuals, the share of each is subject to zakat if it reaches the nisab (equivalent to 595 grams of silver). Outstanding installments do not affect the zakat obligation.
