## Comparing Mortgage Options

Comparing mortgages requires looking beyond the monthly payment to understand total cost over the loan life.

### Key Comparison Factors

- **Monthly payment**: Shorter terms have higher payments but lower total cost
- **Total interest**: The true cost of borrowing over the full term
- **Opportunity cost**: Lower payments free cash for other investments

### Common Comparisons

- 30-year vs 15-year fixed
- Fixed rate vs ARM
- Different lender offers
- Buying points vs no points

### Decision Framework

Choose the lower payment if cash flow is tight or you can invest the difference at a return exceeding the rate savings. Choose the lower total cost if you plan to hold the loan to maturity.

Lösungsbeispiel

Comparing a $350,000 loan at 6.5% for 30 years vs 6.0% for 15 years.

  1. Loan A (30yr at 6.5%): $2,212.24/month
  2. Loan B (15yr at 6.0%): $2,953.98/month
  3. Monthly difference: $2,953.98 - $2,212.24 = $741.74
  4. Loan A total interest: $2,212.24 x 360 - $350,000 = $446,406
  5. Loan B total interest: $2,953.98 x 180 - $350,000 = $181,716
  6. Interest savings with Loan B: $446,406 - $181,716 = $264,690
