Prompt Template

Act as a personal finance educator. Help evaluate whether refinancing a mortgage makes sense for [homeowner situation].

Current mortgage:

- Estimated new payment: [amount if known]

Homeowner goals: [lower monthly payment, pay off faster, switch from variable to fixed, access cash, remove PMI, reduce total interest]
Expected time in home: [years]
Risk tolerance: [low/medium/high]
Other constraints: [credit score, income changes, prepayment penalties, taxes, insurance, local rules]

Deliver:
1. **Plain-English recommendation framework** — what would make refinancing attractive or unattractive
2. **Break-even analysis** — monthly savings, closing cost recovery period, and sensitivity to time in home
3. **Total interest comparison** — current path vs refinance options
4. **Cash flow impact** — monthly payment change and liquidity tradeoffs
5. **Risk checklist** — term reset, fees, variable-rate exposure, PMI, taxes, and opportunity cost
6. **Scenario table** — stay 2 years, 5 years, 10+ years; rates fall again; income drops
7. **Questions for lender/advisor** — fee clarity, rate lock, prepayment rules, and closing timeline
8. **Next steps** — documents to gather and numbers to verify

Example Output

Mortgage Refinance Break-Even Review

**Current loan:** $310,000 balance at 6.75%, 27 years remaining

**Refi option:** 5.95% fixed, 30-year term, $5,200 closing costs

Break-Even

Estimated monthly savings: $178

Closing costs: $5,200

Break-even period: about 29 months

If you expect to stay in the home for more than 3 years, the payment savings may justify the closing costs. If you may sell within 2 years, the refinance is less attractive unless it meaningfully reduces risk, such as switching from an adjustable rate to fixed.

Watch-Out

The new 30-year term lowers the monthly payment but may increase total interest if you only make the minimum payment. Ask the lender for a comparison using the same payoff date as your current loan.

Tips for Best Results

  • 💡Use actual lender estimates, not advertised rates, because fees and points can change the break-even math.
  • 💡Compare both monthly savings and total interest; a lower payment can still cost more over time.
  • 💡Include how long you expect to keep the home because break-even timing is the core decision variable.
  • 💡For personalized advice, verify assumptions with a qualified mortgage or financial professional.
