You say that these banks and their such schemes are helpful, "Quote your example"... If i had taken a loan say from this bank for 10,00,000 and i keep 1 lac in their scheme, and i will be charged interest on 9 lac... Why wouldn't i pay up the bank the 1 lac i have, its like the bank loans me 10 lac and i keep 10 lac i have with the bank and the bank dose not charge me interest (only principal as EMI each month)Dose this solve any purpose these are smart banks (take from you and lend you back)I'd prefer instead pay up the 10 lac as income towards the new house, The EMI'S can be put up as savings. The biggest catch is the amount is liquid, no moment you withdraw you will be penilised and the interest charged will be current and at the discrete of the bank.
