Private equity firm Milestone Capital is likely to close the sale of its promoters stake in the next two months, a source close to the development said here on Tuesday. The real estate-focused fund with assets of around Rs 4,000 crore under management, was put on the block after the death of its founder Ved Prakash Arya last year. The late founder's wife Rubi Arya and brother Ashwein Arya had joined the board in September, 2011.
