Dear friends

I am going to buy 30*60 plot in i-16 or i14 sector for 2 to 3 year investment purpose. I am bit confused, should i buy in i16/2 or i16/4 or i14? Which sector will give more return?

Some people refer me to buy in i16/4 and some in i16/2 i am confused among these 2 alternative.

Please can you base your answer on logics?
