AFAIK there are no "air rights" typically extended as part of real estate transactions and the federal government has the right to regulate air use right down to the surface.

500' AGL is typically the "minimum allowable altitude" for routine (not takeoff or landing, or emergency situation) aircraft operation other than over a congested area (in which case it's 1000' above the highest obstacle within 2000' horizontally).
