What do the counties share, and how do they rank?

Each county uses $500,000.00 property value, 30 ownership years and 3.5% discount rate. The API echoes those inputs in every option. ZIP mappings: 97457 selects Douglas County, OR (FIPS 41019); 97401 selects Lane County, OR (FIPS 41039); 97322 selects Linn County, OR (FIPS 41043). Compare the modeled risk costs to see which county carries the least, lowest first: Lane County, OR $21,763.44; Linn County, OR $22,316.52; Douglas County, OR $25,568.59. The calculation table retains the annual risk-cost estimate and discounted total for each alternative, with the decision row and margin.

What is each county's modeled risk cost per year?

The annual figure is the modeled annual risk cost the API returns for each county. Compare the annual costs to see what the modeled risk cost of each county amounts to in a year.

  • Douglas County, OR: $1,390.20 a year
  • Lane County, OR: $1,183.31 a year
  • Linn County, OR: $1,213.38 a year

What can the comparison tell you?

Dollar figures are RiskBeforeBuy modeled risk costs, not FEMA property valuations, insurance quotes, guaranteed losses or a recommendation to buy. The ranking compares the NPV model only; separate risk-intelligence grades and monthly estimates use a different model and are not mixed into it. The API names FEMA National Risk Index v1.20 and its supporting sources and gives the date each source's rows were fetched (2026-03-29 to 2026-10-11); fetch dates are not the vendors' publication dates. For the NRI it reads "NRI census-tract service v1.20, vendor data last edited 2025-12-16T07:40:18.438Z". For each county the API also gives a scenario-based sensitivity range (2,000 runs varying the inputs) for the composite score and the monthly cost; that range is not a statistical interval and does not cover the NPV ranked here. No calculation sample size is supplied. A numerical difference does not establish statistical significance. The API says of the FBI crime rates: A state rate, applied to every county of the state; not a county measurement. A lower modeled risk cost does not establish a safer parcel or a better purchase.
