Outlands sign/Mountain Man,Grub Shack,Truck Shack,Outlands Simpsons House - keep out or store them?

I struggle with the decision to store all those SH buildings (I hate having to have 10 of everything) and giving up the 150% hidden multiplier. I told myself that when I reached 1150% open multiplier that I would store them, but I passed that and have yet to do it. Instead I keep moving the buildings to the far upper right corner whenever I get new land so I don’t have to look at them much (they don’t generate rent so there’s no reason to go there). Guess what, my Outlands area is butted up next to them. :D
