I'm in the process of buying a new homestead. It has an old log cabin and some pens along with a decent well. Looked at the old log cabin and not good idea for resurrecting(termites and dry rot). This location has plenty of pinion/juniper with lots of brush(needs clearing) and is in central NM at around 6400' and in the mountains. Zone 3 to 4 temps as of late winters and warm as 85F in summer. Will be building the house or buying a green modular. This is also fire country and that must be taken into account.
Am really fond of some of the designs found in the Mollison's "Introduction to Permaculture" and single story is definitely a must. Water catchment is top of the list as is my own power generation and house designed for maximum sun usage. With high winds and bears, solid construction is a must.
Nature is a wonderful teacher. Just when you think you have things figured out, she'll show you how wrong you are...keep trying, you will get it.
