Thought I would share what I started to do across my portfolio to save some coin. My average mortgage rate is around 4.68% (unfortunately some 4.79% fixes are an issue) as of a month ago...now I am in the process of dramatically reducing the cost of my collective mortgages. My target is being the average down to 4.22%. This would result in a saving of approximately $1700 per month or about 21k per annum or aobut 25k with some level of compounding. This is how it works....lets say you have loans of $2m.....reducing your interest rates from 4.7% to say 4.2% average would result in a 50 basis point or 0.5% saving...assuming IO that would equate to a 10k saving per annum. Yes...I know...I know..you can't get rates as low as 4.2% just on variable...but you can combining variable with fixed. Some fixed rates are as low as 3.99%..marry that to better variable rates of say 4.37%...and assuming a 50% split across both rates....you are at an average rate of 4.18%. I had to come with a strategy to pay for my holidays later this year and trade in amount for a new car this year. Ans this is the creative approach I came up with.
