Hello
Hi! I see you have a room for rent! I am very interested but ona budget since I am going to school as well. Would you be willing to rent it for $550?
That's half of the price I set, so I'm afraid not. 
OK, well I do see that the utilities are included, but the room is still only 200 sf, and I need to be able to survive. I can do $650 at most 
You're not going to find a place in this area this cheap with utilities included. Lowest I can do is $800.
I understand completely. Thank you for your time. I actually saw another place a bit bigger with utilities for $650 so I will go there.
