I have a floating home loan with Kotak Mahindra bank, they offer you lower interest rates when you are taking home loan and then whenever RBI sneezes they will increase interest rates by 0.5 %. I have been observing it for past 3 years, their interest rates are around 2 % higher than other banks.
Also you can prepay only once in 6 months. They have a website, which will give you minimum information about loan account. If you wish to get more information, you have to go to their branch which is generally only one in a city (Hyderabad in my case). If you have to take a statement for tax purposes, again you have to go to the bank. I have heard that HDFC offers the same on their website.
All other things apart my main concern is their floating home loan rate , which "floats" 2 % above other banks home loan rates.So my advice, never take a home loan from Kotak Bank, rather than go for some other bank. They were offering me Credit Card, haha, I said never from you.
