Manhattan office carbon fines: $268/ton vs net operating income, pre-1980: hold or sell?

Hold a pre-1980 Manhattan office only if capitalized LL97 penalties stay below retrofit cost and sale leakage. Fines hit $268 per excess ton in 2026. Independent technical note mirroring the canonical version: https://realtigence.com/blog/manhattan-office-carbon-fines-268ton-vs-net-operating-income-pre-1980-hold-or-sell.php

Abstract

Hold a pre-1980 Manhattan office only if capitalized LL97 penalties stay below retrofit cost and sale leakage. Fines hit $268 per excess ton in 2026. Independent technical note mirroring the canonical version: https://realtigence.com/blog/manhattan-office-carbon-fines-268ton-vs-net-operating-income-pre-1980-hold-or-sell.php
