What is the tax exemption, if one buys two flats by taking housing loans.?

am having my own house at Thane ( Maharashtra ) & I am residing presently there. I have taken a home loan for this house & availing tax benefits wrt interest & principal componenets. I am planning to buy another house at my native place ( in MP) after taking another loan. After purchasing, I am planning to rent this house. My query is
a) whether I can avail the tax benefits against this loan along with previous loan.
b) If yes, then how much.
