Hello I am planning for shifting to Chennai, what will be the cost of living in decent area.?

I think you must choose vadapalani,MMDA colony,chetpet,Anna Nagar for a resonable rate for 1BhK house or Flat.Cost will be from INR.5000 to INR.8000.from here u will be having plenty of buses ,transportation facilities to anywhere in chennai. Average with all ur needs it will come INR.8000 to INR.10000 expense.
