Answer key: PMI worksheet

  1. 1. Monthly PMI: $103.83

    1. Loan amount: the price minus the down payment (price × down %)

      $350,000.00−$350,000.00×11%=$311,500.00
    2. Starting loan-to-value: the loan as a share of the price. Lenders use it to decide whether PMI applies

      $311,500.00$350,000.00=89%
    3. Monthly PMI: take the yearly PMI rate of the loan, then split it over 12 months

      $311,500.00×0.4%12=$103.83
    4. You can ask to cancel PMI once the balance reaches 80% of the original value

      $350,000.00×80%=$280,000.00
    5. The balance first reaches that after payment 31. So the PMI you pay up to then is 31 monthly payments of PMI
