Ranked from NOAA 1991-2020 Climate Normals
Driest Counties in Louisiana
The least rainfall in the country. Dry is easier on a building than wet, but it moves the cost somewhere else: irrigation, foundation movement in shrink-swell soils, and in the driest counties the price and reliability of water itself. Figures are NOAA 1991-2020 Climate Normals from the weather station nearest each county seat, so they describe a thirty-year average rather than any single year.

Every figure is modelled on the county's own median home with 20% down at 7.03%. Property tax and electricity are county and state specific; homeowners insurance uses the NAIC average premium for that state, which ranges from 0.16% of home value in Hawaii to 1.16% in Oklahoma. Maintenance and water are national estimates. Full methodology.
