On June 28, 2008 the investor purchased a real estate property in Indiranagar for Rs 1 crore, for which he liquidated his fixed deposits, which were opened from his salary and bonus income over the years and a gift of Rs 25 lakh from his father (sale of agricultural land which he inherited). In 2020, he sold that property for Rs 4 crore to invest in EB-5. We then examine the bank statements to trace the cumulative FDs for Rs 75 lakh from the salary and bonus, inheritance documents, sale deed of agricultural land, followed by sale-purchase agreement of 2008 and corresponding bank statements along with the sale-purchase agreement of 2020 and corresponding bank statements. This exercise goes back until the root source and path of funds are linked and clean, such as sale-purchase agreement, FD receipts, inheritance documents, etc.
