6 steps
- Home equity = 450000 - 250000 = 200000
- Loan-to-value = 100 x 250000 / 450000 = 55.5556%
- Credit line = 85% x 450000 - 250000 = 132500
- Draw-period payment = 50000 x 8.5%/12 = 354.17
- Repayment-period payment = P i / (1 - (1+i)^-n) on 50000 over 240 months = 433.91
- Total interest = 42500 in the draw period + 54139.23 in repayment = 96639.23
