Have you ever considered a small storage shed? My old neighbor had a small Rubbermaid one just big enough for the mower and gas cans and stuff.
There's nowhere I can practically put up a shed, even a small one. I live in a duplex and don't have a backyard. Plus I have to have a storage unit for all my furniture and stuff that doesn't fit in this tiny place. I'm wanting to buy a small house but the real estate market is very limited here.
