Well I gues it is a calculation. If you pay 2k in rent for a place and can rent out a room for 500k. Your nett cost will be 1500. But if you rent for 1600 and there is no space to rent out, your nett cost is 100 higher. The thing is; what is your comfort your worth?
For 100 more you have all privacy. But all small extras make in the end many extras. So if you don’t care about your privacy, pick what make your costs the lowest.
