What are the differences between an open and closed mortgage, and which option would be more beneficial for my financial situation?

An open mortgage allows you to pay off your mortgage in full at any time without penalties, while a closed mortgage has restrictions on prepayment. If you have the financial flexibility to pay off your mortgage early, an open mortgage may be more beneficial. If you prefer stable payments and don't plan on paying off your mortgage early, a closed mortgage may be a better option.
