House property loss

Hi Experts,

I have bought property in Aug-2017 and due to unavoidable situation i need to sell property.

Agreement cost value was 'X'.

Currently i am getting offer for 'X- 5lacs'.

I have below queries:

1) What will be future tax implications?

2) Any issues under IT laws ?

3) If i buy another property of equivalent value 'X' then difference amount xan be used As under tax exemption? If yes under which section apart from 1.5lacs from principal and 2lacs from interest as i have taken home loan?

Many Thanks in advance.

Thanks.
