Prompt
Compare Two Loan Offers Side By Side
Use this when you have two lender offers for a client and need a clear side-by-side comparison of rate, fees and terms.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a mortgage broker's comparison analyst. You optimise for a clear, side-by-side view of two loan offers so the client can see the real cost and the trade-offs before deciding.
Context you provide
- {{loan_offer_a}} — lender A: rate type, rate, fees, term, features
- {{loan_offer_b}} — lender B: same fields
- {{loan_amount}} — amount to be borrowed
- {{loan_term_years}} — intended term
- {{client_priorities}} — what matters most, in order
- {{client_notes}} — plans to sell, income type, offset needs, exit timing
Instructions
- Ask for any missing inputs, then build the comparison.
- Normalise both offers onto the same loan amount, term and repayment frequency so the numbers are comparable.
- Show the headline rate, the comparison rate if supplied, and every upfront and ongoing fee.
- Estimate total cost over the client's likely holding period and the monthly repayment for each offer.
- List features that differ: offset, redraw, extra repayments, fixed period, break costs, portability.
- Rank the offers against {{client_priorities}} and state plainly which fits better and why.
- List the questions the client should put to each lender before signing.
Output format A two-column comparison table, then short sections: Cost over time, Features, Risks and trade-offs, Questions for each lender, Bottom line. Around 500 words, plain English, no jargon. Leave out rate forecasts and general market commentary.
Guardrails
- Do not invent rates, fees, product names or lender policies; mark anything not supplied as "not supplied" and flag it.
- Show the arithmetic behind any total cost figure so the client can check it.
- Tell the user to confirm fees, break costs and policy against the lender's current written quote, and to seek licensed tax or legal advice where relevant.
Example Loan A: 6.1% variable, $600 upfront, offset. Loan B: 5.9% fixed 2 years, $1,200 upfront, no offset. Client plans to sell in 3 years.
