The "Could not estimate prepayment penalty" error

The most common reason why Ownwell cannot generate an estimate for a mortgage switch or refinance.

The Ownwell Digest can include up to three "opportunities" to help clients understand how to save money and build wealth through their home:

  1. Interest Savings Module – Estimates savings or costs from switching a mortgage.

  2. Purchasing Power Module – Shows how much home the client could afford if they were to sell their existing home and invest the proceeds in a new one.

  3. Access Equity Module – Highlights equity the client could unlock by refinancing.

Prepayment Penalty Estimates

Both the Interest Savings Module and the Access Equity Module include an estimate for the prepayment penalty. When the client’s current mortgage has a fixed rate, the prepayment penalty is calculated as the greater of:

  • Three Months’ Interest (easy to estimate), or

  • Interest Rate Differential (IRD) (requires additional variables).

Why This Error Occurs

This error appears because Ownwell could not estimate the IRD penalty. This typically happens when Ownwell is unable to find a rate for a comparable mortgage (a key input for calculating the IRD).

The most common reason is that the Lender Name on the client’s current mortgage is either missing or does not match a recognized lender in Lender Spotlight.

How to Fix It

  1. Open the client’s Current Mortgage form.

  2. Click Edit, then navigate to the Lender Name field.

  3. Select the lender name from the dropdown list of recognized lenders.

Important: Ownwell currently supports only lenders from the broker channel. For example, lenders like RBC are not yet available.

What Happens Next?

This issue does not prevent you from sending the Homeownership Digest. If the IRD penalty cannot be estimated, the Interest Savings Module will simply be hidden.
