2. Rate Comparison Table

When comparing across programs or timeframes:

| Loan Type | Rate | APR | Monthly P&I ($250K) |
|-----------|------|-----|---------------------|
| FHA 30-yr | X.XX% | X.XX% | $X,XXX |
| VA 30-yr  | X.XX% | X.XX% | $X,XXX |
| USDA 30-yr | X.XX% | X.XX% | $X,XXX |
| Conv 30-yr | X.XX% | X.XX% | $X,XXX |

Include MIP/funding fee impact in APR when available.

3. Payment Impact Calculator

Use the standard amortization formula:

M = P × [r(1+r)^n] / [(1+r)^n – 1]

P = loan amount, r = monthly rate, n = total months

Show how rate changes affect monthly payment:

Per 0.25% rate change on $300,000 loan:
  → ~$45/month difference
  → ~$16,200 over 30 years

4. Newsletter-Style Summary

5. Rate Alerts via Cron

Set up recurring rate checks:

"Check FHA/VA/USDA rates every weekday morning and send a summary"
"Alert me if FHA 30-year drops below 6%"

Use cron jobs for scheduled delivery. Store last-known rates in memory/rate-watch-state.json to calculate deltas.
