Is Zakat obligatory on money invested in building and selling real estate, knowing that it has reached the nisab and a hawl has passed over it, and the original capital has increased? And do the installments due to associations affect the obligation of Zakat and how it is calculated, especially since the profits and the original capital will not return until after three to five years?

Zakat is obligatory on capital invested in real estate trade. It is calculated by appraising the value of the land, any structures on it, and building materials when the hawl (one lunar year) passes. One-quarter of one-tenth (2.5%) of your share is to be given if it reaches the nisab (minimum threshold). Zakat must be given annually when one is able. It is permissible to delay it for the poor or for one who fears loss until money becomes available or a sale occurs, then zakat is paid for all past years. The amount added to the capital is subject to zakat, whether it reaches the nisab on its own or when combined with other assets. It may be given with the initial capital or independently. An immediate debt is deducted from the zakatable wealth if there are no other assets to cover it.
