Your current lender can choose to not renew the mortgage with you if they believe you have stacked up debt, will not be able to afford repayments, or if your employment status has changed for the worse. If you have decided to renew your mortgage with a new lender, the chances of being denied are much higher, simply because you are required to submit a new mortgage application. A new mortgage application must meet the new lender’s criteria, such as financial status, the balance of your current mortgage, income, credit score, employment history, mortgage payment history, debts or loans, etc.
