Methodology and data sources
How TrueCarry turns public data into transparent estimates — for example a $300,000 home at a 1.2% effective rate is about $3,600/yr in property tax — with source, method, and confidence on every number.
Every published number shows its confidence level and the data as-of date.
How the estimates are built
Property-tax estimates use county ACS median tax paid divided by county ACS median home value. That produces an effective rate suitable for planning and comparison, not a parcel-level bill.
Insurance estimates start with a NAIC homeowners-insurance state average, scale to the county median home value, and apply a bounded FEMA county-risk adjustment. Because insurance is carrier- and property-specific, the confidence is Low and the range is wide.
How to audit a page
Every indexable estimate page includes a canonical URL, source attribution, data as-of date, method explanation, confidence label, and disclaimer. If a number cannot be traced to a source plus deterministic transform, it should not publish.
The build fails closed when validation, content-contract, or internal-link checks fail, so the production site keeps the last-good release rather than swapping in incomplete pages.
What the confidence labels mean
Medium confidence means the number is suitable for county-level planning, but it still comes from aggregated public data and should not be treated as a parcel-specific bill. Most property-tax estimates are Medium because ACS county medians are broad but reproducible.
Low confidence means the number is useful for budgeting direction but highly sensitive to property-specific details. Homeowners insurance is Low because public NAIC data is historical and carrier quotes can vary quickly by home, coverage, deductible, and market conditions.
