Start a SIP so that you can buy a NEW House for yourself & family. I would explain you through an example. If you want to buy a house after certain number of years you need to plan it now. You can buy your dream home now and keep aside a certain portion of your savings into SIP. As you pay EMI for loan you can pay SIP amount and finish your tenure of loan at a early date.
You need to invest the amount equal to your EMI so that you can build a corpus and repay the loan at a earlier stage. Example you can start invest around 12000 per month and get handsome lumpsum amount after 12 years.
