Normally people think HDFC is a private bank so it is better to go to HDFC than SBI or any other govt bank, but NO, HDFC is not at all customer friendly. your experience with HDFC BANK may be very good, but HDFC home loan dept is WORST among all.
They treat u like are a criminal and want to take away their money. Their procedures are horibble, people in loan sanction dept are NOT AT ALL CUSTOMER FRIENDLY.
SBI or any other Govt bank is 1000% better, their image is that they will take long time, but actually if u compare all the process of govt and HDFC, Govt bank is 10000% better. If u want to go to private sector for home loan go to ICICI or IDBI but HDFC no way.
