GSE WORKFLOW

Fannie Mae D1-3 post-closing QC workflow

D1-3 is best implemented as a process with evidence, ownership, and timing—not as a static PDF checklist copied into a shared drive.

Operational guidance, not legal advice. Validate the workflow against your written QC plan, current agency/investor guidance, and counsel.

Translate the written plan

Document sets, sampling parameters, channel splits, reviewer authority, severity definitions, escalation, and reporting cadence should be explicit organization controls.

Keep calculation and judgment separate

A rules engine can identify a missing document or date variance. The reviewer determines whether source evidence cures it, whether it is a defect, and what corrective action follows.

Reverification is external evidence

A generated letter is only a request. ExactClose distinguishes pending, requested, received, verified, exception, and waived states so a workflow step cannot masquerade as a result.
