Speaking of tie down/hangarage cost, man, an airplane is downright cheap compared to a wife. The airplane is perfectly satisfied with a hangar, which goes for $400 - $500 a month around here, while a wife wants a house. Ours would probably rent for $2700 or so, and then wives like things like kitchen renovations, which cost as much as an engine.
But if you pick the right wife they make more money than they consume. I haven’t been introduced to any airplanes that are net positive on a bank account once you acquire them.
