What a computer can't see
- Condition. A remodeled kitchen and a 1970s one look the same in county records.
- Usable land. Five flat, fenced acres and five steep ones are not the same five acres.
- Water. Well output, irrigation rights and water district access move price on land.
- Outbuildings. Barns, shops and second units are often missing from the county file.
