Stay away from the Mantri Pre-EMI Schemes. We end up paying almost 100% and with a promise that they will reimburse the EMI till possession. After sometime, they stop paying the EMI. They are actually using your ability to get a home loan to fund their projects. Once they stop paying the ore-EMI, you will have the double whammy of paying the EMI to the bank on a loan that you have taken in full.
All their staff are untraceable if you want to speak to them.
