PMI/LMI concept

PMI and LMI are insurance charges tied to higher LTV. They protect lenders and add a monthly cost for borrowers when LTV exceeds certain thresholds.

Threshold idea

Many markets link PMI/LMI to LTV thresholds. Lowering LTV below the entered threshold can reduce or remove the line item.

How to enter in the tool

  • Enter the PMI/LMI percent.
  • Enter the threshold LTV where it applies.
  • Rerun the scenario after each change.
