Latest Answer: In Chennai, if you are looking to buy a flat, in my opinion, west is a friendly area to live in. Even for investment purposes, there are many under construction projects in west. Avadi is a great location especially since Mahindra Lifespaces have started their project under the name of Happinest Avadi. Focused on providing cost effective houses. Not only that, it is conveniently located off Poonamalle Avadi High Road, which is a fast developing area with easy accessibility.
