Good points. Thank you! I actually calculated the rent without the cost of wireless, so I'm undercharging her slightly....but if power usage is much higher than when Suzanne was here, I will have to adjust. I like the wording that you suggest.

I think I'll change it to say that I'm throwing in wireless for free, because that's what I'm really doing.

I turn the wireless of at night because it is unhealthy to be blasted at close range by powerful electromagnetic fields all the time, esp when you sleep, and esp if you have heavy metals deposited in your nervous tissue..... I have been sleeping a room away from the router but I am moving into the same room where it is, and I have a higher powered router, so it's a stout field that I'm sitting in right now....at pelvis level....

I agree to allow her to start paying rent on the day she arrives, and I will continue to expect rent on that day.
