Automated valuations cover more property types and return clearer errors

The automated valuation model values more property types by location, and returns a specific 400 or 422 when a property genuinely cannot be valued automatically.

Changed

  • POST /v1/avm/predict-by-location values a wider range of property types, including maisonettes, retirement flats, park and mobile homes, houseboats, cottages, chalets and lodges, farmhouses, barns, mills, coach houses and other character properties, with no change to the request. A type outside these groups returns the error described below.
  • The valuation endpoints POST /v1/avm/predict, POST /v1/avm/predict-by-location and POST /v1/avm/analysis return a specific client error when a property cannot be valued automatically. An unsupported or missing property type returns 400 with code invalid_property_data, and a property with too few comparable sales returns 422 with code insufficient_data, so you can tell an unvaluable input apart from a service problem.
