Current: $300K at 3% = $1,265/month (renewing Dec 2026)
Refinance NOW: Lock 6.5% = $1,896/month
Wait Until Renewal: Might be 7% = $1,996/month

💡 Option 2: Extend Amortization (Lower Payment)

Strategy: Extend from 25 years → 30 years. Spreads payments over longer period = lower monthly.

Example:

25-Year Amortization: $300K at 6.5% = $1,896/month
30-Year Amortization: $300K at 6.5% = $1,896/month
Savings: $232/month = $13,920 over 5 years
Trade-off: Pay $45K more interest over life of loan

🔄 Option 3: Switch Lenders (Better Rate)

Strategy: Shop 5+ lenders at renewal. Don't auto-renew with current lender!

Example:

Current Lender Offer: 6.8% renewal
Competitor Offer: 6.3% (0.5% lower!)
Savings: $95/month = $5,700 over 5 years
Tip: Use current lender's offer to negotiate with competitors

💰 Option 4: Make Lump Sum Payment (Reduce Balance)

Strategy: Pay down principal before renewal. Lower balance = lower payment.

Example:

Before: $300K at 6.5% = $1,896/month
Pay $50K Lump Sum: $250K at 6.5% = $1,580/month
Savings: $316/month = $18,960 over 5 years
Tip: Use savings, bonus, inheritance, HELOC

✅ FIX: If rates are 6.5% now and trending up, refinance early!

❌ Mistake #4: Ignoring Payment Shock

Why it's bad: Suddenly can't afford $700/month increase = default risk, stress, financial crisis.
