6 Reasons Your Mortgage Pre-Approval Fell Through (and How to Fix Each) (2026)

A pre-approval can feel like the finish line, but in 2026 plenty of buyers watch one unravel between the held rate and closing. The good news: most causes are predictable and fixable. Here are the 6 reasons your mortgage pre-approval fell through — and how to fix each.

The short answer

A pre-approval falls through when something the lender relied on changes before final approval — your credit, income, debt, the property's value, or the rate hold itself. Each problem has a clear fix, and acting early usually saves the deal. Ask Maya if you're not sure which one applies to you.

• Your credit changed
• Your income or employment changed
• Your debt went up
• The property or appraisal came in low
• Your rate hold expired

1. A pre-approval isn't a full approval

A pre-approval is a conditional commitment based on your finances at one moment — not a guarantee. Final approval only happens once you have a specific property the lender appraises and your finances are re-verified. Many "fell through" stories are simply this gap being misunderstood.

The fix: Treat the pre-approval as a budget and a rate hold, not a done deal. Keep your finances frozen until closing, and always include a financing condition in your offer so you can walk away if final approval doesn't come through.

2. Your credit changed

Lenders re-pull your credit before closing. A missed payment, a new credit card, a higher balance, or a fresh hard inquiry can drop your score or signal new risk — enough to change your rate or sink the approval entirely. Co-signing for someone else counts too.

The fix: Don't open or close accounts, miss payments, or apply for new credit between pre-approval and closing. Keep card balances low, and if your score is borderline, ask your broker before making any move that touches your credit file.

3. Your income or employment changed

Lenders need stable, provable income. Switching jobs, moving from salaried to self-employed, dropping to part-time, or relying on a new probationary role can all break the income basis your pre-approval was built on — even if you're earning more.

The fix: Avoid changing jobs or employment type until after closing if you can. If a change is unavoidable, tell your broker immediately so the file can be restructured — a lateral move in the same field with a signed offer is far easier to defend than a brand-new probationary position.

4. Your debt went up

Your pre-approval amount is built on your debt-service ratios. Financing a car, buying furniture on credit, or carrying a bigger card balance raises your monthly obligations and pushes your ratios past the limit — shrinking or voiding the approval. Use the affordability calculator to see how new payments eat into your room.

The fix: Make no major purchases on credit until after you close. If you've already added debt, paying it down or off can restore your ratios — model the impact with the stress-test calculator first.

5. The property or appraisal came in low

Even with your finances in order, the lender lends against the property's appraised value, not the price you offered. If the appraisal comes in below your purchase price, the lender funds less — leaving you to cover the shortfall in cash or renegotiate.

The fix: Don't overpay in a bidding war without a cushion. If an appraisal comes in low, you can challenge it with comparable sales, ask the seller to lower the price, or bring more down payment. A financing condition gives you the room to do this.

6. Your rate hold expired

A pre-approval's rate hold typically lasts 90 to 120 days. If your home search runs long and the hold expires before you close, you may requalify at current rates — and if rates have risen, a higher payment can push your ratios out of bounds and break the approval.

The fix: Track your hold's expiry date and start the renewal or re-shop well before it lapses. A good broker re-qualifies you against current rates and lines up a fresh hold, so you're never caught requalifying at the worst possible moment.

Frequently asked questions

Can a pre-approval be cancelled after I've made an offer?

Yes. A pre-approval is conditional, so the lender can decline at final approval if your credit, income, debt, or the property's appraised value no longer supports the loan. This is why a financing condition in your offer matters.

How long does a mortgage pre-approval last in Canada?

Most pre-approvals and their rate holds last 90 to 120 days. If your search runs longer, the pre-approval can usually be renewed, but you may need to requalify at current rates.

What's the single most common reason pre-approvals fall through?

Taking on new debt or new credit between pre-approval and closing. Financing a car or running up a card balance shifts your debt-service ratios and is one of the easiest deal-breakers to avoid.

Will buying a car affect my mortgage approval?

Often, yes. A car payment adds a monthly obligation that raises your debt ratios and lowers the mortgage you qualify for. Wait until after closing to finance any large purchase.
