Mortgage that can usually be prepaid, refinanced, or discharged early without the same prepayment penalties found in closed mortgage structures.
An open mortgage is a mortgage structure that usually allows the borrower to repay the balance early, refinance, or discharge the mortgage without the same prepayment penalties commonly found in a closed mortgage.
This term is used most often in Canadian and some Commonwealth mortgage contexts.
Open mortgages matter because they trade price for flexibility. Borrowers often accept a higher rate in exchange for the ability to sell, refinance, or prepay aggressively without a major penalty.
That can be useful when the borrower expects a near-term move, a property sale, or a refinancing event.
The defining question is not whether the mortgage is fixed or variable, or whether it is interest-only or self-amortizing. The key issue is whether the borrower can retire the debt early without paying a significant contractual penalty.
| Mortgage feature | Open mortgage | Closed mortgage |
| — | — | — |
| Early payoff flexibility | Usually high | Usually more restricted |
| Prepayment penalty risk | Often low or none | Often more material |
| Typical pricing | Often higher rate | Often lower rate |
| Common use case | Short expected holding period | Longer expected holding period |
When reviewing Open Mortgage, ask whether it changes collateral value, lien priority, property cash flow, borrower capacity, closing funds, servicing, refinancing, or recovery proceeds. If it does, tie Open Mortgage to the loan file, title or contract evidence, underwriting ratio, and exit-risk assumption.
