A married couple/ one family/ an individual having more than two residential property, should pay prohibitory/considerable property tax, so that they do not contribute to speculation of prices.In New Mumbai, you can clearly see more than 50% of the flats though new are empty moreover almost 10% are on rent.
In Mumbai, except for builders in Navi Mumbai, real estate developers take more than 30-50% black money from the flat purchaser. It is big money going to the underworld,corrupt politician and organised criminal syndicate. There has to be a government valuation in each area and transaction cannot be done below that valuation
