Would anyone be able to lend me a hand on where I could find really sketchy looking houses? Like rural, back-country shanties that would still be applicable to the 21st century?
Search under "derelict house". DaveSnow has a few, model #13 There's also one by gawpo50 which could work, though it's a bit big. Try searching under "shotgun shack" and "shotgun house" as well.
