Standard Chartered and a number of other companies such as Citibank, Hindustan Unilever , GSK, Bank of America and HSBC have owned many apartments in prime south Mumbai localities that were given as incentives and perks to their mid to top-level executives in the 1950s and 1960s.With that culture long gone, these companies and banks have resorted to monetising such properties.In the last few years, Citibank has sold over a dozen apartments in Mumbai—five apartments in Colaba’s Harbour Heights building and one each in NCPA Apartments on Nariman Point, Meher Apartments on Altamount Road and Kanti Apartments on MountMary Road in Bandra. In 2011, Standard Chartered and HSBC sold a five-storey residential apartment block, Bishopsgate at Breach Candy to real estate developer Peninsula Land for Rs 272 crore.

Besides falling re-sales, rental yields too have come down from 3 per cent-5 per cent in 2008-11 to 1 per cent-2 per cent in 2011-13.“As of now, the rental yields in south Mumbai are even below 3 per cent and it makes no sense for an investor to come in,” another broker said. With prices of properties not rising as fast as they did in the peak years, investors and speculators had gone out of the market.
