If you have a lease now I'd talk to the current owner asap. It sounds like it will be an upscale development. Most people think the deer are cute until they start destroying their shrubs.
What have you got to loose? Get your foot in the door early and secure what you can. Get permission and go hunt!

Better yet. If you get permission and and don't have to lease you've saved your self some money. If the current owners are retaining some land that won't be developed offer to lease that portion of land. This way the owner can have his cake and eat it too.
