CAmom, while I can relate to your feeling about the work already being done, your broker knows your loan will be funding in a couple of days and should still be available to/for you. I've gone on vacation too while I had transactions set to close, but I was also only a phone call away, had my laptop with WiFi access with me, and actually did work while gone, because THAT'S customer service! Being on vacation is NO EXCUSE when you've got such a major transaction on the line! I GUARANTEE YOU, if you send that cancellation over, your broker will be calling you before you go to bed tonight!
Also, your Truth In Lending should NOT be the place you're learning about $13K in costs. That should have been clear on your "Good Faith" Estimate. While we all hope to build lifetime relationships with our customers, we still have to continue to EARN your business. The mere fact that you brought it back to the same broker should also have assisted them with easing some of your fees for your loyalty. Though 1 point is pretty "standard", nothing says (s)he has to charge you OVER $6000 to do a loan for you, particularly with you being a returning customer. They could have done it for a flat fee of $5000 let's say. But as already stated, what's fair is what both parties can agree upon. I also realize that this is the sole source of income for many, so those BIG paydays on one transaction, particularly in this market are perhaps necessary.
A loan discount generally means you're buying down your rate. Not knowing when you locked that in, I can't say if 5.25 on a jumbo, for someone at a 740 FICO, 50% DTI, $616K, 72% LTV, in CA is bought down or not. But if it's not a buydown, then "I" would sure like to know why it's on a line separate from the origination fee as there's no other "fee" for you to pay that fits in that category. And that .308 is a "fee" for something.
You also mention another $5K, what's it all for? Also, does the final GFE show any "compensation to lender/broker not paid by the borrower"? If so, that's ADDITIONAL profit. And if that item IS there, then that means you could have done better than 5.25% and NOT had the other .308 to pay.
I'm not saying anything's wrong with any of the above, if it works for you. Most people do second guess themselves when spending large amounts of money or going into major debt. Your concerns are natural. And I'm not trying to knock your broker. The tough thing for all of us here is that we don't know and can't see all the details.
So again, the bottom line is, if it works for you go ahead with it so you can execute YOUR plan. If it still doesn't FEEL GOOD to you, and that feeling is not based on the comments of the preceding paragraph, then there's probably something wrong with it, and your clock is still ticking, i.e., time is running out for you to get out of it.
And if "NO ONE" in that office can act on that file, (unbelievable), a quick "scare tactic" to get to the person you need to talk to is to let them know that because of your discomfort, if you don't hear from him by (whatever time), you're sending over a cancellation. TRUST ME, they'll contact him, and he'll be in touch!
Good Luck!
