Coming to bangalore

Hey folks What’s the rent range for a decent 1BHK/2BHK in HSR? Any tips for negotiating deposits (I heard they’re huge) or dealing with landlords? I’m a Sikh and have heard mixed things about inclusivity in Bangalore. Should I be ready for any biases or discrimination? How do people usually handle it? Finally, how much Kannada do I really need to get by? Any good apps or resources for learning?
