What's supposed to happen is the hangar becomes the airport's and they rent it back to you. To me, it's a way to develop the airport for people who really know what they need rather than speculate with government funds. In order to work, the hangar tenants get a good lease on the land for 25 years before they have to rent the hangar back. Trouble is, folks don't like giving their property away at the end of the lease, so they apply pressure from the leverage they have as business owners/tax payers to extend the leases. Some places that works, others not so much, but how do you know in the beginning how it turns out in the end?
