Salt Lake along with EM Bypass and Rajarhat are by far the best planned and developing areas of Kolkata. Sector V of Salt Lake is the IT hub of the city and has a large number of multinational corporations located in the region. This is ideal time to buy in Salt Lake and future prospects very good. High is a relative word but you should be able to make substantial gains over a 5 to 7 year period.
