      Buying a house is the single largest financial investment an individual makes. Yet, in India this act is fraught with risk and individuals depend on weak laws for justice. Occasionally, deviant promoters are called to account as was the case in the detention of Unitech's promoters. This incident shows up the fallout of an absence of proper regulation to cover contracts between buyers and real estate promoters. A real estate bill, which is presently pending in Rajya Sabha, seeks to fill this gap. It has been debated for over two years and should be passed by Parliament in the budget session. 

      India is in the midst of rapid urbanization and urban population is expected to more than double to about 900 million over the next three decades. Unfortunately, even the current population does not have adequate housing. A government estimate in 2012 put the shortage at nearly 19 million units. If this shortage is to be alleviated quickly, India's messy real estate sector needs reforms. 

      The real estate bill seeks to set standards for contracts between buyers and sellers. Transparency, a rare commodity in real estate, is enforced as promoters have to upload project details on the regulators' website. Importantly, standard definitions of terms mean that buyers will not feel cheated after taking possession of a house. In order to protect buyers who pay upfront, a part of the money collected for a real estate project is ring-fenced in a separate bank account. Also, given India on land titles, the real estate bill provides title insurance. This bill has been scrutinized by two parliamentary committees and its passage now brooks no delay. 

      This bill is an important step in cleaning up the real estate market, but the journey should not end with it. State government play a significant role in real estate and they are often the source of problems. Some estimates suggest that real estate developers have to seek approvals of as many as 40 central and state departments, which lead to delays and an escalation in the cost of houses. Sensibly, NDA government's project to provide universal urban housing forces states to institute reforms to access central funding. Without real estate reforms at the level of states, it will not be possible to meet the ambition of making housing accessible for all urban dwellers.

The word escalation in the forth paragraph refers to __________.
