Instead of going round and round a 100 threads searching for something you may never find, why dont you all NRI's ask your property related buy/sell questions here in one thread?
Since I am a Bangalore resident and an avid Real Estate follower/researcher/adviser myself, perhaps I can help and guide. Let us try. Everyone who follows this thread will benefit to some little extent and find information on several localities depending on the questions and answers.
If I know the answer, it would be my pleasure to help/advise.
