Leasing / renting will be an aircraft on a c of a. If you do not need a c of a and can operate on a permit the brake even could be quite low. I have a friend who is hour building in a single seat LAA machine which cost him £6k. He will probably sell it for £6k and in the interim it is using 10lph of mogas an hour, £600 ish per year maintenance and £1000 per year hangarage. Brake even point assuming £120 per hour for hire is around 15 hours and that is outright ownership!
