if you are looking for a property the first things to consider are what will you need for water, power, food, shelter and transportation. Good pure water
should be high on your list, as esp in our area there are some cities that have lousy water but almost everywhere in Michigan if you have a well you get good pure water..but also if you have a stream avail. even the better as you can access it even if there is no power.
If you are looking at a temperate area that gets cold and snow..really look hard at the shelter..roofs that drop a snow load are essential here in our area as otherwise there is a fear of collapse so no flat roofs, also oriented toward the sun here with some good overhangs is helpful to help heat in the winter and to block the high summer sun in the summer.
good soil is helpful and some
trees, but you can plant them if you have to and build the soil..better to start out with at least a good shade tree and some decent soil though...and check the soil for chemical residue...if possible
And I believe the most important things to plant first are of
course your trees, vines and shrubs, esp things like berry bushes and
perennial plants as they will help you out earlier on..and read some good
books as you are shopping for property ..some
permaculture books like
Gaia's Garden and some others and some good quality homesteading books and canning books, cookbooks, etc..
wouldn't hurt to start shopping at thrift stores for some things you might be needing as well..plan ahead.
