Whenever you are doing anything with money, the government wants its share in it. This is a image of the franking of stamp duty on the leave and license agreement between me and my landlord. Renting a house in Bombay is an expensive affair and it is made even worse by other expenses like this stamp duty for the agreement and the money the property agents charge you. If you rent a house through a property agent, he will charge anything from 1 month to 2 months' rent as brokerage and not just once but every time you renew the lease. I guess this is what recurring income means.
