Frequently Asked Questions
What is a conditional approval?
A conditional approval means the underwriter approves the loan subject to receiving additional documentation. Most loans receive conditional approval first — it's normal. CTC tracks every condition and coordinates clearance proactively.
What is the difference between automated and manual underwriting?
Automated underwriting (DU for FNMA, LP for FHLMC) is a computer-based analysis that returns an approval or refer. Manual underwriting means a human reviews the file from scratch — required for some FHA, USDA, and non-agency files.
How long does underwriting take?
First review: 3–7 business days (varies by lender volume). After conditions are submitted: 2–5 additional days. CTC submits complete condition packages to minimize back-and-forth.
