I employee this strategy.
Fixed 4.89% expiry 3/15
Fixed 4.74% expiry 3/16
Fixed 4.95% expiry 11/16
Have approx 50/50 split variable and fixed across all borrowings.
Haha I recall a fair few people waiting to see 5YR @ <5% now that it's hear, it's still scary as it's 5 years.
I don't have any loans/properties suitable for that, but going to be interesting in 6-12months time when I do if the rate is still around.
