Why did my locked rate change before closing?
A rate lock is a contract, and a legitimate change has two things behind it: a real contingency in the lock’s own terms — expiration, or application facts changing, like an appraisal coming in low, a credit score change, or the loan no longer qualifying for the original program — and the updated federal disclosures that follow, since TRID requires changed terms to appear on a revised Loan Estimate (or on a revised Closing Disclosure when the change lands inside the final days before closing). A rate that moves with neither a contractual reason nor that disclosure trail points to one of two things: the lock expired, or you were never actually locked — the phone-call “lock” that surfaces as a higher rate days before closing is the classic bait-and-switch, and it depends on you having no time left to leave.

First, establish whether you were ever locked
A lock exists when you hold a written lock confirmation naming the rate, points, lock date, and expiration date. No document, no lock — verbal assurances and email fragments do not bind anyone. If you have the confirmation, the burden is on the lender to justify any change; if you do not, the honest description of what happened is that a floating quote moved, which is unpleasant but not a broken promise. How rate locks work
The legitimate reasons a locked loan reprices
Real changed circumstances include: the appraisal coming in below the expected value (changing your loan-to-value pricing tier), your credit score changing before closing, income or employment failing verification, the loan amount changing, or the file turning out not to qualify for the original program — for example an adjustable-rate product with qualification rules the borrower ultimately did not meet. These are contingencies built into the lock and the loan approval themselves — and when one changes your terms, TRID requires the change to show up in writing within days: on a revised Loan Estimate, or on a revised Closing Disclosure when the change occurs within four business days of closing (a new Loan Estimate is not permitted that close to consummation). Late paperwork routed through the Closing Disclosure is not automatically foul play; a changed rate with no contractual reason and no updated disclosure is.
The bait-and-switch pattern to recognize
The pattern reported over and over: an aggressively low quote wins your business, weeks pass, and days before closing the rate “has to” change — the program is suddenly unavailable, the lock “didn’t go through,” or you are moved to a different product at a worse price. The mechanics rely on your sunk time and looming closing date. Distinguish it from legitimate repricing by demanding the paper: which changed circumstance, documented where, disclosed when. Vague answers to those three questions are the tell.
Your recourse, in order
One: demand the revised disclosure (a Loan Estimate — or Closing Disclosure near closing) and the specific changed-circumstance justification in writing — lenders who cannot produce it often rediscover the original terms. Two: escalate inside the lender; loan officers have managers, and “honor the written lock or I file complaints” is a sentence that gets meetings. Three: file with the CFPB and your state regulator — regulators act on lock complaints, and lenders know it. Four: price the loan elsewhere; switching lenders before closing is painful but real, and sellers grant extensions more often than panicking borrowers expect.
Insulating yourself up front
Get every lock in writing the day it happens. Keep your credit untouched between application and closing. Ask early whether your product has qualification contingencies that could force a program change. And keep one competing quote warm even after locking — the borrowers with alternatives are the ones bait-and-switch tactics skip.
