Cost of acquisition

Interest paid has already been incorporated in the IT returns u/s 24 every year

But can't we get the benefit of indexation on the same ?

Interest paid to acquire an asset becomes part of cost of acquisition. But there is a dispute, however, that if an assessee has already avail section 24 in ITR, how does one avail the same interest to be part of cost of acquisition. That is double the benefit, which is something quite rare in IT act. 

So, yes, interest paid to acquire a property is part of cost of acquisition. 

But wait for others to reply.
