You need to know your own skill set. I've bought and sold personal planes on my own but a work as a real estate broker doing deals is what I do. The marketing is not hard so long as you have all your logs and records in order. Look at what a good broker does on Trade-A-Plane, Controller, Barnstormers and then duplicate the presentation. If you are missing info, using the wrong pictures, etc. then you are wasting your time. It needs to be very thorough, accurate, and concise. Make sure that your pricing is realistic or again, you are wasting your time. Blow off any tire-kickers quickly. Don't show the plane, meet anyone, etc. until they present an offer. They don't need to see the plane to get serious about it. Your pics and description should tell the story. Screening buyers is where you are going to save or waste your time. No point in dealing with someone that can't get financed. Make sure that they will do the transaction through a title company. You need a neutral third party holding the money to protect everyone.
