We officially locked our rate a week ago at an amazing 3.75%. How awesome is that?! It's for a 30 year fixed loan. We were thrilled in 2008 to refinance our Colorado house to 5.25%. Back then, that was good. The rates right now are really hitting bottom. I am so glad that we didn't have to lock back during summer because it was around 4.5%. It's crazy how the rate can drastically change over a short amount of time.
