I am 28 and moving to a new job that will pay me Rs35,000 each month. I plan to buy a house after 3-5 years and can save Rs15,000-Rs20,000 each month. I have invested in a gold fund and also contribute Rs50,000 towards PPF and invest Rs2,000 a month in HDFC Top 200. Where can I invest for a sizeable down payment for the house? - Deep Dasgupta
