Loan Officers
AI Prompts for Loan Officers: 15 Claude Prompts You Can Copy Today
By Jerad · Updated · 12 min read
What are the best AI prompts for loan officers?
The best AI prompts for loan officers give Claude a role, borrower context with no personal data, the exact output you want, and a compliance line. Save your standing rules once in a Claude Project, then use short prompts for pre-approval follow-up, borrower explainers, agent updates, social posts, and post-closing touches.
Most loan officers try AI the same way. They type "write a follow-up email for a pre-approved buyer," get back something that sounds like a bank brochure, and decide it is not worth the trouble.
The problem is the one-liner. It gives Claude no idea who you are, who the borrower is, or what your compliance team will reject. So it guesses, and the guess is generic.
This post is the prompt library: fifteen complete prompts with [BRACKETS] for your details, grouped by the work loan officers do every week. For the bigger picture of where AI fits in a mortgage business, see AI for loan officers.
What makes a good AI prompt for a loan officer?
A good loan officer prompt has four parts: a role, borrower context without personal data, a specific output, and a compliance line. Leave any one out and the draft gets weaker or riskier.
- Role. A loan officer at a retail lender, a broker shop, a credit union.
- Borrower context, no PII. "First-time buyer, pre-approved, house hunting for six weeks, getting discouraged" is plenty.
- Output. Format, length and channel. A text is a different job than an email.
- Compliance line. No invented rates, payments or terms, and flag anything that needs review.
In my classes, the moment it clicks for most loan officers is when they stop typing one-liners and save the standing instructions once. After that, every prompt can be short because the rules are already loaded.
Here is the line most people need drawn for them:
| Fine to paste | Never paste |
|---|---|
| Loan type and stage (FHA, pre-approved, in underwriting) | Social Security numbers |
| First name only, or "the borrower" | Bank, account or loan numbers |
| General situation ("appraisal came in low") | Full credit reports |
| Your own notes with identifiers removed | Bank statements, tax returns, pay stubs |
| Investor guidelines and program matrices | Anything your company has not approved for AI tools |
| Your approved disclaimer language | Borrower files exported from your LOS |
Not sure which column something belongs in? Ask your compliance department before you paste it.
How do I set up a Claude Project for loan officer work?
Create a Claude Project called "LO Assistant," paste a standing instruction block into it, and upload your reference files. Every chat inside that project then follows the same rules without you retyping them.
Projects are available on all plans, including free (free accounts can have up to five). Anthropic's steps are in the Projects help article. The short version:
- Click Projects in the left sidebar, then + New Project.
- Name it LO Assistant.
- Click Set project instructions and paste the block below.
- Use the + in the project knowledge area to add investor guidelines, program matrices and your approved disclaimers.
Chats inside a project share only the project knowledge, not each other's conversations, so details from one borrower chat don't carry into the next.
You are my writing assistant for my work as a mortgage loan officer. ABOUT ME - Name: [YOUR NAME] - Company: [COMPANY NAME], a [RETAIL LENDER / BROKER / CREDIT UNION / BANK] - Markets I serve: [CITIES OR STATES] - NMLS display rule: [HOW YOUR NMLS ID MUST APPEAR IN MARKETING] - Main loan types: [CONVENTIONAL, FHA, VA, USDA, JUMBO, ETC.] - My referral partners are mostly real estate agents. TONE - Plain English, warm, confident, never salesy. - Short sentences. No jargon unless I ask for it, and define any term you use. - Texts under 300 characters. Emails under 150 words unless I say otherwise. HARD RULES - Never include rates, APRs, payment amounts or down payment figures unless I provide them, and flag any Regulation Z trigger terms for compliance review. - Never promise approval, a rate, a closing date or a specific outcome. - Never ask me for or repeat SSNs, account numbers, or other borrower personal data. If I paste something that looks like it, tell me to remove it. - Do not mention referral fees, gifts or anything of value exchanged with real estate agents. If a co-marketing idea could raise a RESPA question, say so and tell me to check with compliance. - When you use information from my uploaded guidelines, cite the section or page so I can verify it. - If you are not sure about a guideline or rule, say so. Do not guess. EVERY DRAFT - End with a short "Compliance check" list of anything I should have reviewed before sending. - Give me one version unless I ask for options.

AI prompts for pre-approval follow-up and stalled files
These prompts handle approved-but-quiet borrowers and files stalled on documents. Run them inside your LO Assistant project.
Prompt 1: Pre-approval follow-up sequence
Write a 3-touch follow-up sequence for a pre-approved borrower who has not been in touch in [NUMBER] days. Context: [FIRST-TIME BUYER / MOVE-UP BUYER], pre-approved for [LOAN TYPE], working with agent [AGENT FIRST NAME]. Last thing we discussed: [TOPIC]. Touch 1: a text, checking in, no pressure. Touch 2: a short email [NUMBER] days later offering something useful, like a quick call to rerun numbers when they find a house. Touch 3: a text [NUMBER] days after that, giving them an easy way to say "we're pausing." Do not mention rates or payment amounts. Label each touch with the day it goes out.
Prompt 2: Stalled file document nudge
A borrower's file is stalled because we are waiting on these items: [LIST ITEMS, E.G. "updated pay stub, letter of explanation for a large deposit"]. Write a friendly text and a matching email asking for them. Explain in one plain sentence why each item matters, so it doesn't feel like busywork. Tell them the easiest way to send it: [SECURE PORTAL / UPLOAD LINK INSTRUCTIONS]. Do not imply the loan is at risk. Close with my direct number: [PHONE].
Prompt 3: Discouraged buyer re-engagement
A pre-approved buyer has lost [NUMBER] offers and told me they feel like giving up. Write a short, human email that acknowledges the frustration without being cheesy, reminds them their pre-approval is [STATUS, E.G. "still active until DATE"], and offers a 15-minute call to talk through options with their agent [AGENT FIRST NAME]. No rates, no payment figures, no promises about what they will win.
A full pre-approval follow-up system gets its own upcoming post, AI pre-approval follow-up for loan officers.
AI prompts for borrower education explainers
Use these to turn mortgage concepts into plain-English explainers you can send, post or print. Have your compliance department approve each explainer once, then reuse the approved version.
Prompt 4: Appraisal gap explainer
Explain what an appraisal gap is to a first-time buyer who has never heard the term. Use one simple example with round, clearly hypothetical home prices and label them as an example. Do not state a down payment amount, payment amount or rate, and flag any line that could need a disclosure. Cover: what it is, why it happens, and the general options buyers talk through with their agent and lender. Keep it under 200 words. Do not give advice for their specific situation. End with "Talk to me before you write an offer if you're worried about this."
Prompt 5: What a Loan Estimate shows
Write a plain-English walkthrough of the Loan Estimate for a borrower who just received theirs and is overwhelmed. Go page by page in short sections, explaining what each section is for, not what their numbers mean. Tell them which parts are worth comparing between lenders and which questions to bring to me. Under 300 words. Do not include any sample rates, payments or fees.
Prompt 6: "What happens next" explainer
Write a short explainer for borrowers titled "What happens between [STAGE, E.G. 'ACCEPTED OFFER'] and [STAGE, E.G. 'CLOSING']." Use a numbered list of the steps in plain English, note where the borrower has a task, and flag the moments where they should not make big financial changes. Under 250 words. Do not give specific timelines unless I provide them: [TIMELINES IF ANY].
The Loan Estimate and the mortgage advertising rules are both part of the CFPB's Regulation Z. Claude drafts; your compliance team decides what goes out.
AI prompts for realtor partner outreach and weekly agent updates
These prompts cover agent intros, weekly updates and co-marketing ideas. One general caution: RESPA Section 8 covers kickbacks and referral fees, so run any co-marketing past your compliance department first.
Prompt 7: New agent introduction
Write a short intro email to a real estate agent I met at [EVENT OR CONTEXT]. They mostly work with [BUYER TYPE, E.G. "first-time buyers in suburban 3-beds"]. Lead with one specific way I can make their deals smoother, such as [E.G. "same-day pre-approval letters" or "Saturday availability"]. Suggest a 20-minute coffee. Under 120 words. No gifts, no referral talk, no rates.
Prompt 8: Weekly agent partner update
Write a weekly status email to agent [AGENT FIRST NAME] covering our shared files. Use first names only. Files: - [BUYER FIRST NAME]: [STAGE], next step [NEXT STEP], waiting on [ITEM] - [BUYER FIRST NAME]: [STAGE], next step [NEXT STEP], waiting on [ITEM] Format: one line per file, then a one-sentence "anything you need from me?" close. Skimmable on a phone. No borrower financial details.
Share only the file status your company allows you to share with the agent, and ask compliance if you're unsure what counts.
Prompt 9: Co-marketing ideas with a RESPA flag
Give me 5 co-marketing ideas I could do with a real estate agent partner, such as a first-time buyer class or a joint guide. For each idea, add a "Compliance question" line naming what my compliance department would likely want to review (cost sharing, who pays for what, how leads are handled). Do not suggest anything involving a referral fee, gift or payment to the agent.
Agent partners prepping listing appointments will like the AI listing presentation post. It is an easy thing to share in a weekly update.
AI prompts for social posts, video scripts and post-closing touches
This is the marketing and database work that slips when files get busy. Public posts are advertising, so the Regulation Z flag matters most here.
Prompt 10: A week of social posts
Write 5 social posts for [PLATFORM] for a loan officer. Topics: [E.G. "a common pre-approval myth, a quick tip on documents, a question I get every week, a shout-out to agent partners (no names), and a reminder I work Saturdays"]. Each under [NUMBER] words, with a one-line hook. No rates, payments, down payment amounts or "as low as" language. Add my required line at the end of each: [NMLS AND COMPANY DISCLAIMER].
Prompt 11: 60-second video script
Write a 60-second talking-head video script answering this borrower question: "[QUESTION, E.G. 'Should I get pre-approved before I look at houses?']". Structure: a 5-second hook, three short points, and a call to action to [CTA]. Write it the way people talk, with short lines I can read off my phone. Flag any line that could need a disclosure.
Prompt 12: Closing anniversary touch
Write a 1-year closing anniversary text and a slightly longer card message for a past client, [FIRST NAME], who bought a [HOME TYPE, E.G. "townhome"] in [CITY]. Warm, personal, no sales pitch. Offer one useful thing: [E.G. "a reminder to check their homeowners insurance renewal"]. Mention their agent [AGENT FIRST NAME] if natural.
Prompt 13: Rate-watch check-in without promising rates
Write a short check-in email to past clients who asked me to keep an eye on rates for them. Do not state, predict or imply any rate, payment or savings. The message is simply: I'm still watching, here is what I'd need from you if you ever want me to run a review, and you can reply anytime. Under 100 words. End with a "Compliance check" note on anything that could read as a rate promise.
How do I turn a guideline PDF or call notes into something useful?
Upload the guideline or matrix to your LO Assistant project and ask Claude for a quick-reference. For call notes, paste a de-identified recap and ask for to-dos.
Prompt 14: Guideline PDF to quick-reference
Using the [INVESTOR / PROGRAM NAME] guidelines I uploaded to this project, build a one-page quick-reference for [TOPIC, E.G. "self-employed borrower documentation" or "non-occupant co-borrowers"]. Format: a table with Requirement, What it means in plain English, and Source section/page. Add a short "Watch-outs" list at the end. If the guidelines are unclear or silent on something, say so instead of filling the gap.
Verify every line against the source document, and with your underwriting or compliance team, before you rely on it. Guidelines change, and Claude can misread or make things up.
Prompt 15: Call recap into to-dos
Here are my rough notes from a call with [WHO, E.G. "a borrower" or "agent partner"]. Personal details are removed. [PASTE NOTES] Turn this into: 1. A to-do list for me, with owners and due dates where mentioned 2. A to-do list for the other person 3. A short recap email I can send them confirming what we agreed Flag anything that sounds like a commitment I should double-check before putting in writing.
How do I turn a prompt into a reusable Claude skill?
When you run the same prompt every week, turn it into a Claude skill. A skill is a reusable playbook that teaches Claude a specific workflow, and Claude uses it automatically when it is relevant.
You do not need to write code. Describe your process in a chat and Claude builds the skill, then you turn it on in Settings > Capabilities > Skills. A good first candidate is Prompt 8, the weekly agent update, because the format never changes.
I want to turn my weekly agent partner update into a reusable skill. Here's how I do it now: [DESCRIBE YOUR PROCESS, E.G. "every Friday I list each shared file with first name, stage, next step and what we're waiting on, then send one email per agent"]. Here's an example of a good one: [PASTE A PAST UPDATE WITH NAMES REMOVED]. Rules: first names only, no borrower financial details, no rates, end with "anything you need from me?" Build this as a skill and tell me how to turn it on.
The Claude skills post walks through the full process; the steps are the same for loan officers. The agent-side library to share with partners is Claude prompts for real estate agents.
What to do this week
- Create the LO Assistant project and paste the instruction block. Fill in every bracket.
- Upload one investor guideline or program matrix and run Prompt 14 on a topic you get asked about often.
- Pick three prompts from this list that match your busiest tasks and run them on real (de-identified) situations.
- Send the borrower explainers to your compliance department for approval so you can reuse them.
- Turn the prompt you used most into a skill.
Start with the project. Once the standing instructions are saved, every prompt above gets shorter and the drafts get better.
FAQ
Can loan officers use AI to write borrower emails?
Yes, as long as the AI drafts and you review. Claude can write follow-up emails, status updates and explainers, but every draft should go through your company's compliance review before it reaches a borrower. Keep personal data like SSNs and account numbers out of the prompt entirely.
Is it safe to put borrower information into ChatGPT or Claude?
Never paste SSNs, account numbers, full credit reports or bank statements into any AI tool your company has not approved. Describe the situation instead, such as a first-time buyer with a pending appraisal. Check with your compliance department on what your company allows.
What is a Regulation Z trigger term in mortgage marketing?
Trigger terms are specific details, such as a stated down payment, number of payments or payment amount, that require additional disclosures under Regulation Z (the Truth in Lending Act rules). AI tools can drop these into marketing copy without warning. Have Claude flag them and send anything flagged to your compliance department.
What is the best AI for mortgage loan officers?
The best tool is the one you set up with standing instructions so you are not retyping rules every time. Claude Projects let you save your role, tone, compliance rules and investor guidelines once, and every chat in that project uses them. Projects are available on all Claude plans, including free.
Can Claude read my LOS or pull credit?
No. Claude cannot see your LOS, CRM or credit vendor. You give it the information, such as a de-identified file summary or a guideline PDF, and it works with what you provide. Always verify its output, because Claude can make mistakes.
