*blowing the dust off this thread*
Thanks everyone. My issue is my time - I have none of it, but am ok financially. With that, I will not be a "good" partner because I won't spend 5 minutes cleaning it, organizing maintenance, ensuring things are current, etc. - except what I need to do as part of my pre-flight obviously. Hence, the leaseback is attractive to me because the school will ensure it's maintained (yes, I will pay the maint bills) and current. I've been renting from this school for a couple years now, so I know they are very good about maintenance and cleanliness (airplanes are kept spotless, maintenance is proactive, and squawks are addressed in short order).
So, if the leaseback allows me to own a plane at a marginally better cost position than a partnership (and spend zero time helping), I'm good. I've done the math, and estimate that I will break even if it rents for 30 hours each month (accounting for insurance, plane payment, tie-down, and maintenance).
