Moving to Chennai!!

Hi guys! Newly moving to Chennai for my post graduation course. In the process of house hunting, I have come across a gated community which I actually liked in north chennai, but its 5 km from MMC/RGGGH, and the journey from there to GH seems to go through some pretty crowded areas. Brokers are advising me not to go for this apartment in North Chennai as “The area is problematic, not suitable for doctors”. They did not specify the details. What could it be and how bad could it be? I’m new to chennai and I don’t know anything about the city. Pls guide!
