618k on the mortgage; two sub accounts - 243k at 4.3% for the next 5 years and 370k at 2.4% for the next 4 years. DH job now looking under threat. Was spitballing and wondered - if we downsized, is it possible to exit one sub account early and pay the exit fees on that, and port the other mortgage to a smaller property? Has anyone ever heard of doing such a thing?
