Refinancing
Interest rates aren't the best they've ever been right now, but they're still fairly low. Refinancing a variable rate loan to a fixed rate right now could still be a good idea, as rates may go up in the future.
Rates are on a slight upswing, but they're still significantly lower than they have been in the past. Locking in a low, fixed rate can help ease worries about payments increasing in the future. Many companies are eager to help with the refinancing process, and will make it as easy as possible.
