Clarity. Confidence. A Mortgage That Works for You.
When Is a Commitment Not a Commitment?
September 23, 2026 | Posted by: Daryl Johnson
You got the letter. The lender is committed. You are basically done, right?
Not quite. A mortgage commitment is not what most people think it is. Here is when a commitment is not really a commitment.
A commitment is conditional
Almost every mortgage commitment is issued 'subject to' a list of conditions. Typical ones include:
- Verifying your income with final documents
- An appraisal confirming the property value
- No material change to your employment, debts, or credit
Until every condition is satisfied, the lender can still walk away. The commitment is a promise with an asterisk, and the asterisk matters.
A pre-approval is even softer
A pre-approval is not a commitment at all. Most pre-approvals are really just a rate hold: the lender says 'we will hold this rate for up to 120 days while you shop.' It is not a promise to fund your mortgage. Plenty of buyers learn this distinction at the worst possible moment.
How people accidentally cancel their own commitment
This is the part that stings, because it is always avoidable. Between commitment and closing day, do not:
- Buy or lease a car (new debt changes your ratios)
- Change jobs or go self-employed
- Miss a payment on anything
- Make large unexplained deposits into your bank account
- Co-sign a loan for someone else
Any of these can trigger a re-check, and a re-check can unwind the whole approval. My rule after you are approved: do not touch anything. No new credit, no big moves, no surprises.
When does it become real?
A commitment becomes firm when all conditions are met and the lender issues clear-to-close instructions to your lawyer. That is the moment you can breathe. Everything before that is progress, not a guarantee.
The bottom line
Treat your commitment like it is fragile, because it is. Keep your financial life boring between approval and closing day, get your documents in early, and ask what your conditions are instead of assuming there are none.
