A mortgage commitment letter is a written, conditional promise from your lender to fund your loan if you satisfy a listed set of requirements. Clear to close means those requirements have all been reviewed and accepted, and your file has moved from underwriting to the closing department. Understanding the mortgage commitment letter versus clear to close comes down to that gap: the letter puts you in line, and clear to close is the lender confirming there is nothing left to check.
What a Commitment Letter Actually Promises
A commitment letter states the loan amount, interest rate, and program type, whether that’s fixed-rate, adjustable-rate, FHA, or conventional. It carries an expiration date, usually 30 to 90 days out, and if you don’t close before that date, you can lose the terms you locked in.
You’ll get one of two versions. A conditional commitment letter says the lender is willing to lend but still needs specific documents or verifications before final sign-off. A final commitment letter says underwriting has finished vetting both your finances and the property. Most buyers see the conditional version first and work the remaining items down from there.
The letter also does work outside your relationship with the lender. Sellers and their agents treat it as evidence that your financing is real, not just a pre-approval built on a soft credit pull and a stated income. A seller taking their house off the market is relying on that letter.
The Conditions That Sit Between the Two Milestones
The conditions listed in your commitment letter are the to-do list separating you from clear to close. Underwriters call these prior-to-close conditions, and they won’t sign off until every one is satisfied. Typical items include:
- Recent pay stubs, usually covering the most recent 30 days, to confirm your income and employment haven’t shifted.
- Bank statements. Fannie Mae requires the most recent two full months of account activity to verify assets and source your down payment.1Fannie Mae. Selling Guide – Verification of Deposits and Assets
- Homeowners insurance in place before closing. Fannie Mae requires coverage equal to the lesser of 100% of the replacement cost or the unpaid loan balance, as long as that amount is at least 80% of the replacement cost.2Fannie Mae.

- A satisfactory appraisal. The property has to appraise at or above the purchase price to meet the lender’s loan-to-value ratio. If it comes in low, you either bring more cash or renegotiate.
- A clean title search confirming no liens, judgments, or ownership disputes on the property.
Send everything digitally the moment you get the conditions list. Every day a document sits with you is a day closer to your rate lock or financing contingency deadline. When something is unclear, call your loan officer instead of guessing.
What Clear to Close Means and What Comes Next
Clear to close is the moment the underwriter confirms every condition has been reviewed, verified, and accepted. Your file leaves underwriting for the closing department, and the legal loan documents get prepared. At that point, the lender has committed specific funds to your transaction and is ready to execute the mortgage note.
Clear to close is not quite the same as “final approval,” though the two terms sometimes get used interchangeably. Final approval means the underwriter has approved your application; you may still have a handful of conditions to clean up. Clear to close comes after that, once the last items are checked off.3Consumer Financial Protection Bureau. What Is a Mortgage Closing
Most buyers sign within three to seven days after receiving clear-to-close status. The minimum is three business days, because the lender still has to deliver your Closing Disclosure and observe the mandatory waiting period before you can sign.
Things That Can Still Derail Your Loan
A commitment letter is not a guarantee, and even clear to close isn’t absolutely bulletproof. Lenders routinely pull your credit again shortly before closing to confirm nothing has changed. If the second check turns up new debt, a missed payment, or a lower score, the file can go back through underwriting or be denied outright.
The most common ways borrowers sink their own closings:
- Opening new credit accounts. The store card offered at checkout can shift your debt-to-income ratio enough to disqualify you.
- Financing large purchases. Furniture or a car bought on credit changes the debt profile the underwriter approved.
- Changing jobs. Employment stability is a core underwriting factor, and switching employers, moving from salaried to commission, or starting a business can all cause problems.
- Moving large sums of money. Unexplained deposits or transfers raise sourcing questions, and if the underwriter can’t trace the money, it becomes a condition you may not be able to clear.
The simplest rule between the commitment letter and closing: change nothing about your financial life. The underwriter approved a specific snapshot, and anything that alters it introduces risk.
The Three-Day Closing Disclosure Rule
Once you’re clear to close, your lender has to send you a Closing Disclosure at least three business days before you sign. This is a federal requirement under Regulation Z, and it exists so you have time to review every number before signing.4eCFR. 12 CFR 1026.19 – Certain Mortgage and Variable-Rate Transactions
The disclosure lays out your final loan terms, monthly payment, interest rate, closing costs, and cash due at the table. Compare it line by line against the Loan Estimate you received at application. Some fees can’t increase at all, like the lender’s origination charges and appraisal fees. Others can increase by up to 10% in total, such as title search fees from a provider the lender selected. Prepaid items like homeowners insurance and property taxes have no cap because they’re set by third parties.
Three specific changes restart the three-day clock: if the annual percentage rate becomes inaccurate, if the loan product changes (say, from an FHA loan to a conventional loan), or if a prepayment penalty is added.4eCFR. 12 CFR 1026.19 – Certain Mortgage and Variable-Rate Transactions Other corrections can be handled on a revised disclosure without a reset. This matters because a reset can push your closing back and put your rate lock or lease timing at risk.
Financing Contingency and Rate Lock: The Clocks Running in the Background
Most purchase agreements include a financing contingency giving you a set number of days to secure a mortgage commitment. If you can’t get approved inside that window, you can walk away and get your earnest money back. Miss the deadline without that protection, and you can lose the deposit and face additional claims from the seller.
The commitment letter you produce has to be clean enough to satisfy the contingency. A letter with unusual conditions the lender is unlikely to clear won’t do it. Standard verifications like employment and appraisal are expected. A condition that essentially says the lender will lend if they feel like it doesn’t provide the assurance the contingency requires.
If underwriting runs behind, you can either negotiate an extension with the seller or terminate the contract while the contingency is still active. The seller isn’t obligated to grant the extension, so delays carry real financial risk.
The interest rate in your commitment letter is typically locked for the same period as the letter. If closing takes longer than expected and the lock expires, you’ll pay to extend, usually in 15-day increments at 0.125% to 0.375% of the loan amount per extension. On a $400,000 loan, that’s roughly $500 to $1,500 each time. If rates dropped since your original lock, some lenders offer a float-down option; if rates climbed, an expired lock without an extension means repricing at whatever the market offers that day.
