Howdy neighbor! I'm near Milton, PA and had similar ideas a few years back.
I ended up buying an old farmhouse instead.
Maybe building codes, taxes, etc. are all specific to the location.
Around here, most small lots aren't rural. Most rural lots aren't small.
Might be able to pry a few unfarmable acres from a farmer, but they you will be in the spray zone.
Working from home can be a challenge due to poor Internet access, especially in rural areas. Starlink is good, but pricey. Some rural areas are close enough to highways to have cell tower coverage you could use for Internet, but that can also be pricey for the quality. Very little DSL/cable outside of towns.
Maybe start trying to find a property first?
Always happy to help local permies if I can
