grades refreshed — the watch-list stays current

NY DFS's 2018 guidance recommends that state-chartered lenders review outstanding building-code violations on rent-stabilized collateral as part of pre-loan due diligence. Collateral Watch surfaces those open violations across your portfolio and monitors them continuously. Grades and signals are OpenStoop's analytical opinions derived from public NYC records — not official government ratings, legal findings, or a regulatory determination.
