I sold a residential house, bought it in 2015, during the last financial year and earned Rs 40 lakh in net profits. With the Rs 20 lakhs long-term capital gain, I am planning to invest Rs 20 lakhs in capital gains bonds of NHAI and use the remaining Rs 20 lakhs for buying a residential house property. The property will cost me Rs 50 lakhs. I will pay Rs 20 lakhs as margin money and fund the balance Rs 30 lakhs through a home loan. Will I be eligible to claim an exemption in respect of Rs. 20 lakhs paid as margin money for the residential house?
