We just did.. Went down from 5.95% to 3.45% . I must have been sleeping as I didn't realize the rates dropped so much from what I had about 6 yrs ago. I guess it was even at 2.9% at one point. But we are saving almost 300$ a month on payments including paying off a car we owed . The total cost was about 2200$ of that about half was origination fee which can be written off next year on taxes . I didn't even realize my house equity had increased as much as it did .. Anyone buy a house or refi recently ? What rate did u get?
