I just saw the subject line and thought, "No," before I even read the post.
For 50%, I lose money. People don't think about the cost of additional electricity, water, gas (heating water and cooking). Climate control - not guests = no income = I don't heat/cool those areas of the house. Guests = climate control = you need to pay up. And then there's my labor, oh, and the cost of the food.
Anyway, if it gets to it (you know, the arguers) I just explain I will lose money on that. And thank goodness the other place is willing to make such an offer so he'll have a place to stay! (can't find a smiley that smiles AND rolls its eyes).
My answer is
NO way, but just for fun wouldn't it be tempting to say -
Sure you can have the room for $ 1/2 price
If you want lights that would be an additional $
If you want A/C (or heat) that would be an additional $
Oh and do you need water - add $
You didn't say you wanted a bed, well add $ and $ for linens,
etc...
