Compare the same property assumptions
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: 32401 selects Bay County, FL (FIPS 12005); 34429 selects Citrus County, FL (FIPS 12017); 32958 selects Indian River County, FL (FIPS 12061). The calculation table retains the annual risk-cost estimate and discounted total for each alternative, with the decision row and margin.
What the comparison can 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. The results omit purchase price, financing, ordinary maintenance and any insurance quote specific to the home. A lower modeled risk cost is one part of a location decision.

Each calculator link carries the ZIP and every shared input. The deployed lookup reads the ZIP automatically; property value, years and discount rate are not automatically applied. Full NPV controls and results require a paid account. Set property value to $500,000.00, years to 30, and the field labeled Mortgage Rate to 3.5%; that field supplies the calculator's discount rate. The API source link preserves the exact comparison inputs; full results require your own product key.
