Is zakat obligatory on the sale value of land that was leased and its rental income was subject to zakat annually, after its sale?

If the land was not purchased with the intention of trade and profit, then there is no Zakat (definition) on it. Zakat becomes obligatory on its price after one lunar year has passed, at a rate of 2.5%. However, if it was purchased with the intention of selling, it is considered a trade commodity, and Zakat becomes obligatory on its price when one year has passed on the original capital with which it was purchased.
