Should i take loan on my name and builder promising to pay EMI?

Somebody from DSA informed me that there Buy back type home loan where i no need to pay any amount amount to bank , only builder will provide the EMI, only home loan would be issued on my name and builder would be given 5% of loan amount to me. as i asked around 6 lacs DSA people telling me that they will apply 3-4 bank in same time so that where you will get huge amount sanctioned in same eligibility which if i apply in one bankthat can be very low. pls advice me how much risk is there in this kind of loans.
