I hate this too. I hate renting. I wish I could afford my own house.
My realestate agents says that I don't have to be home, but like heck I am going to have complete strangers come into my house (yeah I know it's not actually my house, but mine and my kids' things are in there) and going through things. I have been there about 15 months and luckily only had a few inpections/interests.
