The sole benefit of buying new is factory warranty.
Make sure it covers commercial operations, you never know with the small print.
Consider selling them when the warranty runs out.
Be exceptionally well protected as far as your other assets. It’s been mentioned above.
If someone dies, even with blatant pilot error the family will sue everyone in sight. The aircraft manufacturer, the avionics manufacturer, the engine manufacturer, the maintenance facility and the owner.
The flight school will prioritize the aircraft use.
Probably theirs first then the lease backs.
$160/hr is also not cheap.
As an asst Chief flight instructor I was part of a small team to test/review a LSA for flightschool use. Apart from a very high time (10,000+) and one very low time (just soloed) pilot everyone would have needed at least one more checkout flight. One heavy footed private pilot got as far as a low altitude spin entry on his first flight.
He would have died had he been alone.
LSA’s are not all baby airplanes.
They’re light, underpowered and jittery.
Some have scary low demonstrated crosswind limitations and at least some time ago the accident statistics were downright scary.
