If you are uncertain about your rate and if it was in fact locked according to your wishes, you can ask for a confirmation. I would ask for an updated good faith estimate showing the rate and all costs associated with the loan and escrow. Did your rate include a rebate to the loan originator? Points?How much is the origination fee? I am not asking you to post these things , just putting out the items that you want to follow up on so that there are no surprises in case you are not looking at them already.
