Don't know if I should buy or rent a flat.

Hi all. I am 35 M married and have a 10month old daughter. I have a flat in BLR but in I have to move to Hyd as I am switching company. Have to stay in rent again. I am into IT. My wife is a college teacher. I am from Chhattisgarh. I don't know if I should buy a house in Hyd and sell the one in BLR? Or should I stay on rent forever? Job changes. City changes. But I also have a dream of living in my own house. How you guys are managing this when both are working couple?
