Punch-list cost model

Every open item at final walk traced to the re-trip cost, the rework and the closing-delay carry it produces, against the checklist standard already written into the walk. Catch it before possession, not after.

A checklist that says "pass" is a guess about what closing week costs

Every final walk already carries an open-item allowance — a number set once, in a checklist template, and never checked against what closing week actually costs. Nobody joins the walk findings to the trade invoicing system until the re-trip bill lands, so a heavy punch list shows up as a scramble at closing, not a QA decision made before the crew leaves site.

Every over-threshold home compared against the standard the checklist already promised. The gap is traced to a driver — a re-trip charge, a materials line, a closing delay — so a superintendent can escalate this week, not explain a closing-week scramble after the fact.
