Well one could argue that at 5.99%, historically much lower than the average 5 yr fixed rate over the last 50 years....
But on the other hand some people believe that variable is the way to go, because you'll never beat the banks at their own game...
So just wondering what each person's perspectives are in regards to their own circumstances...
You could also argue that historically interest rates have been well over 7%, thus any fixed rate below 7% is a good deal. The flaw in this logic is will the next few years be an environment where rates are likely to increase or will they stay low - frankly I don't have a clue.
There's a good chance that rates will drop further and possibly fixed with also drop, so we may not have seen the bottom yet. It's also highly likely that rates will increase within the forseeable future, so most fixed rates would be financially worth fixing now overall; just don't complain if they drop lower first. Of course we may be at the bottom right now so by waiting you may miss out on the lowest rates. The third option is they could just keep dropping down to 2% and fixing now would be expensive.
In other words, as Rolf said, "How long is a piece of string?" Better to make your decision based on what you're willing and able to pay and also be willing to wear the potenital negative consiquences of your decision.
Either way you can't beat the banks. Lenders buy fixed rate money at a certain price, then factor in their margin. They also borrow the money on fixed rates, so effectively by allowing you fix with any particular product, the lenders have locked their profit for a specified period of time. They don't care if rates rise or fall from that point as they've guaranteed their margin.
Borrowers should take the same attitude to fixed rates, not being too concerned if they rise or fall, as it guarantees their repayment amount.
