Fixing your home loan can be fun at times when rates are dropping. Ofcourse guessing the future course of interest rates is attractive but near impossible. Generally I am one that believes that flipping a coin can be almost as accurate as experts most of the time.
However it can be important that the strategy aligns with your gut feeling.
Fixing rates for two to three years can be great if interest rates reach a low point then. However if you expect interest rates to be higher at that point, a longer term rate could be handy.
