New Delhi [India], March 31 (ANI/NewsVoir): The ultra-rich Indians and foreign investors continue to be significant contributors to India's realty sector's growth. A report by Knight Frank highlights that about 29 per cent of India's ultra-high-net-worth individuals (UHNWIs) purchased a residential property in 2021. The report also shows that the foreign capital flow into Indian real estate jumped over three-fold to USD 23.9 billion during the 2017-21 period as compared to the previous five years which is a quite promising sign.
