An excellent concept for a series. As you say, we can't help asking questions about the houses so immediately the viewer is engaged.
I don't think 1 works as well as the other two. The building is smaller and the more interesting details are lost somewhat in the shaded front area. Another time of day and a bit closer would have brought it closer to the other two.
Two oozes character. The end wall is facelike, kind of reminiscent of a Halloween pumpkin. Loved the roof with the iron covering peeling back to show the old shingles beneath - there had to be a story there. Add the leaning walls and the variety of wooden surfaces.
Three is uncomfortably like the old motel where the guests regret they didn't drive passed. The half open blind top right, is disturbing. Someone might still be here - looking for your approach. The angle Chris has chosen builds the suspense. The viewer feels as though they are hiding.
A series worth expanding Chris.
