DESCRIPTION
The issuing organization seeks a secure, enterprise-grade artificial intelligence modelling software platform designed for property tax mass appraisal. The platform must be scalable for high-volume spatial and property-characteristics data to improve annual valuation accuracy, productivity, and transparency.
The solution must not operate exclusively as a proprietary black box. It must independently model and report land and improvement components for residential improved property, commercial improved property, and vacant land. The platform must support multiple statistical and machine-learning methodologies and enable comparison or combination of model results.
Required capabilities include evaluating appraisal neighbourhoods and recommending alternative boundaries based on physical barriers, location, property characteristics, sales behaviour, and statistically measurable market differences. The platform must provide interactive mapping for parcel data, modelled values, sales, model residuals, data-quality issues, ratio-study results, and geographic influences, with filtering, selection, comparison, and export functions. It must also generate reproducible parcel-level valuation reports suitable for internal review, taxpayer conferences, administrative appeals, and court proceedings. Questions must be submitted by October 2, 2026.
