Itr 1 instead of 2

In Ay 1415, assesse has claimed deduction of interest on housing loan and filed itr 2( along with salary and other sources ). However, no interest on such housing loan paid in Ay 1516 hence return filed under itr 1. So was it necessary to disclose details of house property as self occupied and claiming nav of sop as nil. Will this mistake lead to scrutiny or any other consequences ? Please provide valuable feedback. Regards Raj.
