India's property market is luring global realty funds as the fast-growing economy boosts demand for office space, houses and shopping malls, but soaring prices pose a risk of a meltdown.

Realty funds have assets worth about $4.7 billion in India, with industry estimates on growth varying widely from $30 billion to $90 billion by 2010.

'There is hell of a lot more capital available than good transactions,' David Ellington, trustee at the San Francisco Employees' Retirement System, said during his visit to India.

'That is going to heat up the market.'
