I believe you didn't read my post that well.  As I said, I charge less than market rate for the rents.  Currently I would be receiving an extra $400/month if I did maximize the amount I could get.  Greedy people don't do that.  

Would you willingly accept 20% less (the same as my loss per year by not charging market rate) than your car is worth when you sell it?  If you expect to get what it is worth, does that make you greedy?

I believe people thinking that a seller has to give them a discount are called "entitled."
