C-PACE pencils when three things line up: your senior is one of the (growing but still short) list of lenders with a standard consent process, your energy scope is genuinely 15%+ of project cost, and you can hold through the assessment's prepayment window.
On a $14M conversion, the consent fight is usually two to four weeks with a lender who has done it before — and a dead end with one who hasn't. Ask your lender for their C-PACE consent precedent before you spend another dollar on structuring. Their answer tells you everything.
