Hi Katie
I'm not far from Grand Rapids, my wife and I built at Ottawa Executive (Z98) 6 years ago. There is one house for sale and 7 or 8 lots. We just had one house sell last winter and the new owners are really nice people. I also met the people that bought a lot several months ago, they plan on building in 1 or 2 years.
The association did have some hard feelings with the airport owners but things are now much better. Send me a PM if you'd like to discuss, better yet come on out and I'll show you around.
Gary
