ENTERPRISE CLIENT REQUIRED: Altus Group ARGUS is enterprise CRE software; automated open API access assumption creates enterprise_required; automated must be an institutional real estate organization with Altus Group agreement. ARGUS MODELS ARE COMPLEX: ARGUS DCF models have specific assumptions and conventions; automated simplified real estate assumption creates model_configuration_error for ARGUS-specific modeling rules; automated must understand ARGUS Enterprise modeling conventions. DATA LICENSING RESTRICTS USAGE: Altus Market Insights data is licensed for specific use cases; automated unrestricted data redistribution assumption creates data_licensing_violation; automated must comply with Altus data usage license per subscription. PROPERTY DATA COVERAGE IS MARKET-SPECIFIC: Altus market data coverage varies by geography; automated global market data assumption creates no_data_for_market in markets outside Altus coverage; automated must verify Altus data coverage for specific markets.

Agent Metadata
Known Gotchas
- ⚠ ARGUS ENTERPRISE MODELS HAVE SPECIFIC STRUCTURE: ARGUS DCF models follow specific formatting (market leasing assumptions, recovery structures, cap rates); automated generic DCF assumption creates model_validation_error for non-ARGUS structured inputs; automated must understand ARGUS Enterprise model architecture
- ⚠ PROPERTY DATA IS CONTRIBUTED PLUS MODELED: Altus market data combines contributed transactions and modeled estimates; automated certainty assumption creates methodology_footnote for modeled vs. actual transaction data; automated must distinguish modeled from observed market data
- ⚠ PORTFOLIO AGGREGATION REQUIRES STANDARDIZATION: Aggregating multiple ARGUS property models requires consistent assumption sets; automated heterogeneous model aggregation creates inconsistent_portfolio_metrics; automated must standardize key assumptions across portfolio models for comparable aggregation
- ⚠ CRE APPRAISAL HAS REGULATORY STANDARDS: Commercial real estate appraisal must comply with USPAP (US) or RICS (UK); automated non-USPAP valuation assumption creates regulatory_non-compliance for regulated appraisal uses; automated must ensure ARGUS outputs meet applicable appraisal standards
