For Mortgage Loan Processors ·
What you'll accomplish
By the end of this guide, you'll have a Claude Project set up as your personal Mortgage Processing Assistant — a persistent AI that already knows your lender's condition types, your preferred letter style, and common loan scenarios. Every conversation starts with full context, so you stop re-explaining yourself 20 times a day.
What you'll need
What you should see: The main Claude chat interface with your name at the top. Troubleshooting: If you don't see "Projects" in the left sidebar, your account may be on the free tier — Projects require Pro.
What you should see: A project page with a "Project Instructions" area and a conversation window.
This is the key step. Click the "Project Instructions" section at the top. This is where you tell Claude who it's working for and what it knows. Copy and customize this template:
You are a mortgage loan processing assistant for [YOUR NAME] at [LENDER NAME].
My role: Loan Processor, managing [X] active files supporting [X] loan officers.
Loan programs I process: [e.g., Conventional, FHA, VA, USDA]
Common condition types I handle:
- Large deposit LOEs (need 12 months sourcing for deposits over 50% of monthly income)
- Employment gap LOEs (any gap over 30 days in the last 2 years)
- Rental income documentation (Schedule E, 75% vacancy factor for FNMA)
- Self-employment income (24 months tax returns, business bank statements)
- Credit inquiry LOEs (must explain all inquiries within 120 days of application)
My preferred letter tone: [Professional and warm / Formal and brief / Plain language, accessible]
My lender's name: [LENDER NAME]
My NMLS#: [YOUR NMLS NUMBER, if comfortable]
When I ask you to draft a letter or email, always:
1. Use the borrower's name I provide
2. Use formal business letter format unless I say otherwise
3. End with my signature placeholder: [YOUR NAME], Loan Processor, [LENDER NAME]
4. Keep letters under 300 words unless complexity requires more
Click Save when done.
In the conversation window below the instructions, type: "Draft a condition letter to Sarah and Tom Nguyen asking for a Letter of Explanation for the $9,200 deposit in their Chase checking account on February 18th. They mentioned it was from selling their car."
What you should see: A complete, formatted condition letter that uses the Nguyens' names, references your lender name from the instructions, and matches your preferred style — without you having to explain any of the context. Troubleshooting: If it doesn't use your lender name, check that you saved the Project Instructions. If the format is off, add more specific formatting guidance to the instructions.
Add a "Files" section to your Project (look for "Add content" or paper clip icon) and upload:
These uploaded files become context that Claude uses for every conversation in this Project.
What you should see: Uploaded files listed in the Project's knowledge section.
Each morning, open your Claude Project instead of starting from scratch. The context is always there. You can ask:
Condition letter: "Draft a condition letter to [BORROWER NAMES] asking for [SPECIFIC CONDITION]. They are [BRIEF DESCRIPTION OF BORROWER SITUATION]. Closing target: [DATE]."
Follow-up email (3rd request): "Write an urgent but professional follow-up email to [NAME] — this is our third request for [DOCUMENT]. We need it by [DATE] or the closing may be delayed."
LO pipeline summary: "Write a pipeline summary email to loan officer [NAME] covering these 4 files: [FILE 1: status, outstanding], [FILE 2], [FILE 3], [FILE 4]."
Appraisal issue memo: "Draft a memo explaining that the appraisal for [ADDRESS] came in at $[APPRAISED VALUE] vs. the contract price of $[PRICE]. The variance is [X%]. Impact on LTV: [DESCRIPTION]."
Borrower closing cost explanation: "Write an email to [BORROWER] explaining why their cash to close changed from $[OLD AMOUNT] to $[NEW AMOUNT]. The reason is [EXPLANATION]."
