This page documents the planned data approach — listing market data, rent comparables, HUD-style fair market rents and county assessor records — and how conflicting records for the same building are reconciled rather than silently resolved.
It also states the underwriting defaults used by the cash-flow model, the known limits of whole-address valuation models on duplexes and fourplexes, and the checklist of items you must verify yourself: leases, utility responsibility, tax reassessment, insurance and physical condition. No return is promised and no advice is given.
