I have seen all these shows on TV, Storage Wars, Auction Hunters, etc. and I can't help but thinking about this. Most of the stuff they find is semi-crap. I don't have a storage unit, but I have rented in the past. Usually for short periods (clean the house out to show it for realtors, between years of college, etc.). I can't see using it as an extension of my house/garage unless I had something that was absolutely worth keeping there. For instance, I see camping junk and Christmas stuff in these things....assuming it costs $60 (I'm sure on the LOW end) to keep stuff in one, that's $720/year to keep it. It had better be worth it. Plus, then there's the hassle of actually going there to get it, etc.
I have
thought about keeping my track stuff in one, but I can stash my little tire trailer in my mom's garage, and the tires in the garage and basement. I do have a 2 car garage and a decent basement. I guess you either make it up in mortgage, storage or don't own it.
So, I'm curious, what kinds of things are YOU storing offsite.
