Plain-English explanation
Underwriting reviews credit, income, assets, the property, and program rules. Files may pass through an AUS, a human underwriter, or both.
Why it matters
Clean documentation and a well-structured file speed underwriting and reduce surprises.

A real-world example
Underwriting requests two additional bank statements and an explanation for a large deposit, then issues a conditional approval.
Educational and illustrative only
A common misunderstanding
Underwriting isn't a single quick check — it's a full review of credit, income, assets, and the property that can involve multiple rounds of conditions.
