I've been looking at a lot of rural properties lately and something I've started paying way more attention to is where the septic system can actually go.
Not whether the property has "good soil."
Where the house is going, where the well is going, where the driveway is going, setbacks, drain field, reserve area, all of it.
Had a parcel recently that looked like a pretty normal homestead property from the aerial. Plenty of open ground and enough acreage for what someone would probably want to do with it.
Then I started looking at the soil map and the flood map together.
The areas that looked best for putting a house were also the areas where I wouldn't want to be counting on a conventional septic system.
That doesn't necessarily make the property unbuildable. It just means you can't look at acreage and assume you have that much usable space.
For homestead land, I think the septic location is one of those things that's worth figuring out before you get attached to the property.
A beautiful 10 acres isn't much of a homestead if the only place you can put the house and septic doesn't work.
