a little thought i had for you bski.....
will you use the sweetspot for a small cabin you cannot logically add on to? do you plan to retire there? consider a design that could ultimately become yer final resting home.
i know if i was searching for property for use as a full time residence or retirement pad, it would hurt the value IMO to find a beautiful acreage, beautiful pond, and the building sweetspot wasted on a small cabin.
forgive me if you have addressed this concept already...
