Pre-EMI interest is available for deduction u/s 24 in 5 equal installment after the assessee obtains the possession, and the principal portion also is not available for deduction u/s 80C till possession.

Pre-EMI and EMI both eligible for deduction u/s 24 after the completion of the construction in 5 equal installments.

Pre Emi interest should not be confused with construction stage. It is the interest during the broken period between disbursement of loan and time when EMI starts. Generally EMI starts on a fixed date of the month following disbursement of loan.If it relates to post construction then it is allowed as deduction in the year in which it is paid, just like interest included in EMI. If it relates to interest during construction stage, it will be allowed in 5 instalments post construction.
