Change in Lender Credits after committed to Loan

[Jerome S.]

I've been working with LoanDepot on a cash out refi for one of our rentals (a duplex).  I've locked in the rate, paid for the appraisal (which was completed today), paid for my credit check and submitted all the paperwork.  Basically, they're just waiting on the appraisal price to be within a certain amount and they can move to get the closing documents.  

HOWEVER, today I just received an updated Loan Estimate with a $1260 reduction in the lender credits.  Basically they were providing a lender credit of -2352 and today they updated that to -1092.  How is this even fair at the late hour in the game?  I expect the appraisal to be received tomorrow and was just talking with the loan officer today about potentially scheduling closing in the next 10 days.

Love to hear your thoughts on such an infuriating 'bait and switch' move.
