Not leaving on a jet plane
So, would you rather spend $200K on a home or an airplane? To live in of course. This guy chose a 727.

What does it cost?: I paid $100K for the aircraft. But I think retired 727-200’s are significantly lees expensive now. The costs of staging site rent, wing and tail removal, moving, and other logistics will total slightly over another $100K. So the project total will be a bit over $200K.

Why not just live in a stick house like everyone else?: The practical reasons: I don’t mean to offend, but wood is in my view a terrible building material. It biodegrades - it’s termite chow. And microbe (rot) chow. Or it’s firewood. It just depends upon which happens first. It’s a relatively weak material, and it’s secured with low tech fasteners using low tech techniques. And traditional rectangular designs are inferior structurally - they unreasonably sacrifice strength for boxy ergonomics (geodesic structures solve this problem at least). Rectangular stick homes can’t withstand sever winds or severe earthquakes, they frequently kill people when they explode into flames, they’re easily broken into by burglars, they’re leaky, and they degrade quickly. On the positive side, they are relatively economical to build (although geodesic homes are too).
