Renting the house in Delhi is certainly better option. In a locality like Dwarka, you can easily rent in a 3 BHK society flat for less than 10000 Rs. per month and the initial deposit is just three months rent. While if you want to buy the same, you have to shell out atleast 45 lakhs. In 25 lakh you cant even buy a 2 BHK DDA flat while 1 BHK is simply not available vishal
