As we all know that there is a big hand behind the Builder and the Real Estate Sector. I think the move is to not facilitate the Common/Poor man, its rather to make money for politician and Builders. For Ex: If you don't Buy the house there is no transaction so there is no money for the to eat for politician and Builders. When the TAX get exempted then GOVT is earning less. Price is same so we are not benefiting. But politician and Builders people are earning money.
