Ben - I've NEVER leased any of the machines that I've owned to flying schools.
I have allowed safe and trusted friends to play with them for a fair remuneration - the friend benefits from lower costs, I benefit because the a/c is used and all my costs are covered.
There is a lot of talk on here about unscrupulous folk..............
all I know is that there are a lot of used car salesmen in the world, unfortunately a lot are in aviation!!
