Actually Yesterday only i visited Keerthi krishna viva and i was pretty interested in booking it.
I had a discussion with Mahadev who made me talk to the SBI representative for Krishna viva and he explained me that they do not pre-aprroval from SBI but the project was legally cleared from SBI(There is a difference).
May be we can discuss more-Please call me if needed to my number(9739604545).
Thansk,
