Cross-NPA comparison engine for Thai distressed properties. Finds comparable NPA properties by GPS proximity, computes area benchmarks (median/p25/p75), and returns type-specific comparison results (condo, land, house, commercial). Condos additionally use external market data from market_adapter when available. Non-condo is cross-NPA only — no external market data exists yet.
NPA property alert system. Scans ALL provider databases (LED, SAM, BAM, JAM, KTB, KBANK) for newly added properties, price drops, best deals, properties near BTS/MRT, and upcoming auctions. Can generate daily reports and run on schedule.
Run structured analysis (financial, property, data) using the hybrid ralph pattern. Decomposes research questions into parallel investigation tracks with verification.
