1.false & overhyping of india's business prospects by foreign agencies to tempt india for opening market.
2.free run by govt. to speculators and black money in real estate.
3.greed among indian people.they rushed to buy real estate as if no tommorrow and encouraged speculators and black money.
4. too liberal distribution of real estate loans by banks. now most of the banks are facing sub-prime crisis.
prices rose by 300%-400% and this bloody UPA govt. was sleeping and happily supporting it. high real estate prices and high rentals are also major reasons for inflation.medium business can not even rent ,forget buying a property for office in metros.also genuine house buyers,retired person's dreams were shattered due to high prices.imagine 300-400 % rise in 2.5 years.even decent upper middle class could not purchase any house now people should maintain patience and wait till this year till prices are at realistic levels and real estate bubble bursts with a loud bang as was few years back.
