Richer valuation analysis: hedonic adjustments, confidence decomposition, and price spread

The detailed valuation analysis response now exposes per-comparable hedonic adjustments, RICS-aligned confidence decomposition, and price spread reliability metrics.

Added

  • Each comparable in the POST /v1/avm/analysis response now includes a hedonicAdjustment object with originalPrice, adjustedPrice, adjustmentFactor, a per-attribute breakdown (bedroomAdjustment, propertyTypeAdjustment, floorAreaAdjustment), and the sourceLevel of the coefficients used.
  • Comparables also gain adjustedPrice, address, pricePerSqm, and an estimatedFloorArea flag indicating whether floor area was estimated rather than verified.
  • The confidence object is expanded with modelAgreement, dataQuality, modelWeights, limitingFactors, and a comparablesQuality block (highQualityRatio, floorAreaCoverage, avgDistanceKm, avgTransactionAgeMonths).
  • A new priceSpread object reports valuation reliability via forecastStdDev, fsdBand, coefficientOfVariation, sameBedSpreadPct, and warnings. All new fields are optional, so existing integrations are unaffected.
