If your business fails and you're unable to meet your mortgage repayments, it's important to communicate with your lender as soon as possible. Lenders may offer options like mortgage holidays, temporary interest-only payments, or restructuring of your mortgage to make it more manageable. It's crucial not to ignore the problem, as defaulting on your mortgage can have serious consequences, including the possibility of losing your home. In such situations, seeking financial advice or consulting with a debt advisor can also provide guidance on managing your finances and exploring available options.
