I've recently tried selling my house but I need to clear out all the space in my house first. I tried putting stuff in the attic but it was filled with junk and it wouldn't let me pick anything up. I think it would help a lot of people if the attic has unlimited space so you can pick up as much items from your houses when you want. Or add the Quick Sell feature to attics so you can sell stuff and not have to go putting stuff in your backpack or trash everything.
