Thanks for asking all of us! I have been searching for property for my sister to retire to and we have been whittling down the lists: Essentials, Preferables, Would-Be-Nices, and Absolutely-Nots. Does this property have enough of these qualities or do you have funds or the ability to make improvements?
My first step in helping my sister is to go to the county and get all the records they have (probably not much if it is raw land).
Next is to visit the department of ecology and do a well log search. Here is the site for
Washington State. Check out your state or county for similar information. This will provide information on your neighbors' wells: how deep and type of soil.
next: soil type. How deep is the soil, what types of slope? Twice, I thought I had found the perfect house for my sister but the land was so steep as to be unusable - I think the best thing to do with steep slopes is the forest them but that slope meant that I wouldn't be able to safely manage the woodlot.
Curious if you have already purchased or are in the process and your geographic location. My answer will be more specific for the rural USA but are things to think about no matter where you are. What does open land mean in this context?
Top things to consider and/or fund soon are access (roads - both county and on-site), water (well and septic), power (off-grid or cost to connect to utility), any structures (including state of dis-repair), topography, the density of groundcover/forest.
Lots of things to consider as you ponder this transition. Hope this helps :)
