Why not buy an old RV? Or, like someone I actually know, go to an ocean community and look around for a large, old boat that perhaps has no engine and electronics, etc. (maybe one that has been in a boatyard for a few years). You could probably talk a retired person into letting you park it in their side yard for about $150.00 a month with an extension cord and water hose for as long as you wanted to stay. Most will have a galley, bath, several bunks and usually equipped for dockside electrical hook-up (just like an RV). I have seen 24' boats like what I just described complete with a trailer for under $3,000.00. They practically give them away when the engines seize because older models aren't worth retofitting with newer engines, etc. Hey, you want cheap and very unique that won't leak a drop when it rains? Here's your answer. You could also use it as a great pick-up line: "want to come down and have some wine on my yacht?"
