Dear Members My client Purchased House in FY13-14,for 2cr and sold some other house in FY 14-15,for 1cr. he was eligible for exemption u/s54.,since he purchased house prior to 1yr of selling the existing house.now the question is purchase payments were done in EMI.,Was he eligible for interest Payments Deduction u/s 24.,And Extra Amount paid on Purchase was 90L,Any eligible exemptions for this??? Thanks in advance
