My work is slowing at the moment and probably will be for 3-6 months, and given I'm on commission this means my pay is severely affected. I can manage my mortgage payments as long as my tenants keep paying rent and no major issues pop up, but I wondered if it's worthwhile applying for deferment of payments for up to 6 months just to ensure I have a buffer and I can sleep at night. I have about $1.4m worth of loans with CBA fixed @ 4.09% IO. They told me all their customers are eligible (not sure if this is entirely correct, surely you have to meet certain criteria) and that my fixed loan period would not be extended. Deferring for 6 months means I wouldn't have to come up with ~$30k worth of interest. The fixed loans expire in October so they would be variable by the time I have to start paying again so I'm assuming the rate will be around 3% or less, or I may consider fixing for a couple years at this time. But assuming 3%, it means my interest payments will increase by $900 pa which is easily absorbable over my portfolio, especially given my total payments will come down by about $14k pa at this time anyway, assuming the rate does drop 1%. I was thinking of utilising the deferment offer to keep a buffer. If I don't end up needing the funds, I could just keep them in an offset account, or invest them and earn a lot more than 3% elsewhere. For eg, I'm fairly confident that buying some blue chip shares at the moment would return a lot more than 3% in the next year. Seems like a no brainer really. Is there anything I'm mising here?
