When you get ctc, that's it. Don't buy anything until after closing though
At least you got the closing disclosure in time to close Friday. You may very well not get the clear to close until Thursday.....but as long as the underwriter approves it for closing, you should be good on your timeline. I'm told it used to be very common practice to not have a HUD-1 (old closing form) till right before closing.
