Orange font (i.e. optional input) means that a formula exists to approximate the value, but that you may need/want to change the value. Currently, the ‘Make Ready’ formula in the Stabilized pro forma on the MF-OpSt tab takes the actual Make Ready costs from the first stabilized year, which value is driven by the Make Ready assumptions in columns AL and AM of the MF-RR tab . That may not always be the underwriter’s intention, so Spencer left the cell as an optional input.
