I saw this little cabin last time I was there from the road, it's a cutie. Just came on the market last week at $54K. It appears to be unpermitted and off grid, seemingly like some walls are bamboo, not sure. At anyrate, they've done a nice job with it. But it's not for me, too expensive and too open for part-time use.
And here's another lot for $30k, hard to tell much because of the jungle.
And this lot is listed at $26K, has a neighbor right next door, across the street there is an abandoned campout (I guess) and some foliage.
Beyond these, there are two more I find interesting, one listed at $26K and is more or less open like the lot above and on the same street. The other is listed at $30K and is located on the same street as the bamboo cabin above and is heavily jungled. I'm thinking I rather like something a little more open as less bugs and coqui frogs. The jungled lot we went by in the evening and it was LOUD!
