My advise, don't even think about doing a lease back unless you can approach it from a highly disciplined and purely business point of view – most who enter into these agreements do it because they think that somehow it will lower their ownership costs. Yeah right. Basically, in most instances, over the long haul all you end up doing is substadizing someone else's flying. Don't be seduced by a salesman's or flight school's promises - ask for references. Talk to some of their long-term leaseback owners. My bet is that they won't have any.
On lease backs, the airplanes tend to get flown a lot initially, then as they start to get a bit "dog eared" the usage drops off. You only options are to lower the rental price or spend the money to refurbish it and "make it pretty" again. Put yourself in a renters position, if there were two airplanes at a flight school renting for the same price, which one would you want to schedule first - one that was nice looking or one that had a bunch of obvious wear? The flight school owner doesn't really care; he doesn't own your airplane. He's only counting the percentage that he's taking right off the top. In fact, it's to their advantage to rent the more expensive airplane. If you haven't budgeted the money for periodic refurbishment your rental income will tend to drop off over time. Don't let the promise of additional rental income being able to offset your ownership costs seduce you into buying more airplane than you can afford to purchase or maintain by yourself. Also, seeing “your” airplane abused by ham-handed renters will annoy most owners.
The bottom line for most guys is at the very best, it MIGHT defer (not eliminate) some of your costs for a while; but eventually you've got to pay the piper. Worst case scenario, it can run up yours costs significantly.
