For our 2 bedroom, its 140ish when we stay there regularly. When we aren't there but 3-4 days a month like lately, its 50-65 dollars. But I'm pretty sure someone (maintenace) has been in there... Because we turn everything off, and un plug everything. When we come home, a lamp is usually on, and tv is plugged up.
For my one bedroom / studio I had way back when, it was really cheap, only like 30.00.
Then I moved to a two bedroom with my brother who was a gamer and we were paying well over 100.00, lol.
Now I rent a small 3 bedroom house and we pay like 150 - 200, but I am really bad about shutting things off and managing my heat / AC. During the peak of the summer, we were getting over 300.00 electric bills.....it was insane.
