ROBUST dimension

Burden

Taxes relative to property value. Burden asks how heavy the recurring property-tax cost is relative to the property's supported market-value context.

What Burden measures

An annual tax bill by itself lacks context. Burden relates the recurring property tax to a supported market value so two properties with very different prices can be compared on the same basic carrying-cost relationship.

Current production mapping: the property score calculates tax divided by Watchdog market value and maps the effective relationship against fixed anchors. The current code uses approximately 1.2% as the favorable anchor and 3.6% as the pressured anchor.

Why it carries 30%

Burden represents the recurring expense actually carried by the taxpayer, so the current property model gives it the largest weight. That weighting is still subject to statewide sensitivity testing before any future model is promoted.

Illustrative comparison
Property A$9,000 tax on $650,000 value
Property B$8,000 tax on $300,000 value

Property B has the lower dollar bill but the heavier tax burden relative to value. This is why Watchdog does not compare annual taxes alone.

Evidence behind Burden

  • Annual property tax from governed property records.
  • Supported/equalized market-value estimate.
  • Municipal assessment-to-sale ratio context used in the market-value estimate.
  • Model-version anchors used to convert the relationship into the component score.

What it does not mean

A higher Burden score does not mean a property is more affordable overall. Watchdog does not include mortgage terms, household income, insurance, utilities, maintenance or personal finances in this component.

Research direction

Watchdog should periodically validate burden anchors against statewide distributions and test whether residential property classes require different normalization. Any anchor change should be versioned and sensitivity-tested.
