Switch the water/land ratio of the property. How much dirt do you need anyway?
Dang I like the way you think! For me that would be a 27 acre lake and 3 acres of dirt. I could live with that.
Heck I could live with 29.5 acre lake and .5 of dirt.
Or 30 acres of lake and live on a house boat!
Well, maybe that's just getting greedy.
