Great move. I did something similar too a few years back, whereby I took on a "higher" rate using the government offered interest rates on our retirement accounts. This was during a time where bank interests were at an all time low and everyone was saying it'd be silly to pay that slightly higher rate.
I liked the stability and guarantee offered though, and didn't think it was possible for the bank rates to stay that low forever. Take note that in my country, once you reject that "government" loan option, you can never ever go back to it.
I see lots of worried neighbours around me now fretting about when their loan is due to be refinanced and the significantly higher rates kick in. Bullet dodged I guess.
Sometimes it comes down to luck of the draw and timing. We were lucky with the timing, but smart with taking the option. A lot of people who should have known better, didn't take the option, though their timing was okay. It is "sliding doors" in some cases though.
I have a lot of bullet wounds in my life, but will take this as a win :)
