Capital gain on sale of land

" Since I am receiving income  from two house property my auditor says that we cannot  claim exemption for the capital gain on sale of property .Is it correct?"

Not correct.

You can get exemption u/s. 54/54EC as residential house property sold after more than 3 years holding period.

Thanks for  the Reply Sir. I have sold a vacant land  and my auditor says  the timelimit  for investment in 54EC  has expired and 54  is available only for sale of house property .Since  I have sold a  vacant land  and showing rental income of more than one property  I cannot claim Exemption for third property which is under construction(I have used my sale proceed to construct the property ) . I have not filed the return Yet . Please help

Can the rental incomes from two units in the same building  be treated  as one residential property and exemption claimed under Section 54F.?
