My client is owning 4 residential property, out of which one property will b sold just after receiving possession in December 2019. (purchase agreement made in 2013) .another under construction property is bought in May 2018.

My query.
1. the property which will b sold will be long term capital asset?
2. how can I take benefits of exemption against property which was purchased in May 2018.
