DU Error Code 118337 | How to Fix

The error code 118337 most commonly refers to a specific issue in the Fannie Mae Desktop Underwriter (DU) system used by mortgage lenders.

Here is the breakdown for the mortgage system error, followed by advice if you are asking about the telecom provider.

If you are using Mortgage Software (Fannie Mae DU)

Error Message: “Subject Property Type Code is missing from the 1003 file, or the property and/or project data element combinations are invalid.”

This error prevents you from running findings because the system detects a conflict in how you described the property.

Common Causes

1. Invalid “Manufactured Home” Combo: This is the most frequent cause. You likely listed a Manufactured Home with an “Attached” status. Fannie Mae DU logic typically rejects “Manufactured Home” + “Attached” because most manufactured homes are detached units.

2. Missing Fields: The “Attachment Type” (Attached/Detached) or “Structure Type” fields may be blank in your Loan Origination System (LOS) like Encompass, Calyx Point, or LendingPad.

How to Fix It

1. Open your loan file (Form 1003) and navigate to the Subject Property section.

2. Locate the Property Information fields.

3. Check the Attachment Type:

   • If it is a Manufactured Home, ensure it is set to Detached (unless it is a rare condo/co-op manufactured project that specifically allows otherwise, but “Detached” usually clears the error).

4. Ensure Project Type is filled out if applicable (e.g., for a condo).

5. Save and Re-submit to DU.
