Q: I purchased a property seven months ago with the intention for staying at first but then decided to sell to purchase my house. Do I have to pay zakaat on the total amount including the rental income?
A: In the case you mentioned, you only need to pay zakaat on rental accrued if such rental has been saved up and one Islamic year has passed over it. There is no zakaat on the total value of the property.
And Allah Ta'ala knows best
