This sounds like a tough decision. When buying or renting a house, one of my main considerations has been the layout of the house itself. I want lots of light and a kitchen that isn't buried away from everything. Perhaps the layout of the various options can nudge you in the right direction?

Can't understand this non-freedom units to math it, but a few principles to consider:

• Houses are malleable and depreciating assets, not an investment consideration, everything above the minimum is a luxury as long as you have forward ability to modify the structure.
• Land is hard money, no matter what place and time in history you look back to, the difference between serfdom and freedom is being landed.
• Not all land is equal, acreage is not a perfect unit of measure... the waterfront is more scarce than acres of field as it offers its own utility. Also consider flood risk.
• You already narrowed down the structures to something livable, so what piece of land can be made into your families garden of Eden? We all have an innate desire to return to Eden.

My pick is A, because you put it first. Also it has a lot of land for growing food, and also, its closest to civilization so you can quickly get groceries when your dream of gardening inevitably fails.

B has a cool river, and old store building, but looks like it's close to a busy intersection. River isn't your property so can't easily use it for hydro power, etc. River could be a concern if floods are common.

C has irregular property shape and is way too close to the neighbors.
