Simple things Los Alamos homeowners can do with this information.
Historical averages, not a quote. Homeowners figures are inflation-adjusted averages from the U.S. Treasury Federal Insurance Office "Supporting Underlying Metrics" (2018–2022, published January 2025). They cover HO-3/HO-5 policies from participating private insurers and exclude state residual-market plans (such as FAIR plans and Citizens), surplus-lines and flood coverage. Treasury notes that individual ZIP codes can contain data anomalies. Your price depends on your home, coverage and insurer.
