Dear Sandhya,
I am 50% agree with wils24's reply, i would like to modify it further. The interest which has been paid in the given case is PRECONSUTRUCTION INTEREST. Preconsturction interest means the interest from the date of borrowal of the loan upto the end of the financial year immediately preceding the financial year in which acquistion made or construction was completed. The said pre consturction interest shall be allowed in five equal installments commencing from the financial year in which the property's consturction was completed.
In simple words you have to follow following procedure.
1. Identify the date of borrowal of the loan
2. Identify the date of completion
3. Identify the last date of the financial year immediately preceding the date of completion / Acquisition.
4. Pre consturction period = calculated period from step 1 to step 3
5. Pre consturction Interest = Pre construction period as per step 4 * rate of interest*Amount of Loan
6. Allowable Prior period interest = prior period interest as per Step 5 / 5 equal installment.
In connection with HRA, he can get the benefit of HRA.
