I did talk to absolute mortgage guy he didn’t say that refinance is not worth in my case (may be because I didn’t ask) I am also on 4.375%. I think it all depends upon how much is your current balance so that rebate can cover the closing cost can leave some thing for you to keep. I did last refinance through Amerisave. They are fine but one needs to be familiar with refinancing and keep communicating with them. I think Sheldon is being recommended here earlier. How to reach him? I am thinking of getting quote from him in future.
