I bought 5 acres of land here in the area around lake Tenkiller in late 2016 and finished building our house in July 2017. The hardest part for me has been just dealing with all of the clay, rocks, and trees. I don't mind getting outside and doing manual labor all day on a Saturday, but our soil is a reddish colored clay (very sticky when wet) that is absolutely full of rocks.
On the plus side, I have all of the rock I'll ever need for landscape projects. On the downside, digging anything takes a ton of work.
It looks like you have very Sandy soil at your property. I'm sure that poses it's own problems, and keeping wildlife away from your food crops will probably be tough as well. Keep up the hard work though. It is coming along nicely.
