Regarding Self Occupied Property

Assessee is getting rent from indus tower and Bsnl tower as he is given land on lease for monthly around Rs.15000 & 6500. And he is having 2 houses in his name.

1. When filing last year Income Tax, doesn't disclose 2 houses. There is no HL (No deductions and No gain) for both the houses. Should I disclose in this FY as self occupied

2. Whether assessee can self occupy 2 houses ?

3. What if I didn't disclose it as it is self occupied ?
