So the girlfriend and I have been toying with looking at land purchases. The idea is that although we dont have the money to buy a house/buildings now, we should buy the land now because it surely wont be cheaper later on. Theres one place, 80 Acres with a stream for $120k, that sounds nice. I wouldnt mind burying a cargo container into a hillside just to give me a place to stash stuff until the day the construction starts, but apparently the UK has a nice little industry with portable buildings that look like they just re-tooled a cargo container manufacturing plant.

You know, from the “weekend cabin/retreat” standpoint you could do alot worse than rehabbing a cargo container.
