Pre-Approval Is Not Approval: Why Your Mortgage Can Still Collapse After an Accepted Offer
The lender's rate-hold letter says you're approved for $875,000. You write an offer on a Saanich bungalow at $840,000. The seller accepts. Then, four days before closing, your mortgage broker calls with news that begins with "I'm sorry."
This happens more often than most first-time buyers expect, and the cause is usually not hidden fees or sudden rule changes. It's that the pre-approval was never actually an approval. It was a conditional estimate based on incomplete information, and the condition just failed.
What the pre-approval actually measures
When a lender pre-approves you, they are making a prediction about your ability to service a mortgage of a certain size. They pull your credit. They review your income documents. They calculate your debt ratios. What they do not do is review the property you are going to buy, appraise its value, or run your file through the final underwriting process that happens when a purchase agreement exists.
The estimate holds only if three things remain stable between pre-approval and closing: your financial position, the property's value and condition, and the lending rules themselves. Any one of those can shift.
In British Columbia, the stress test adds a layer most buyers don't account for until it matters. You qualify based on the higher of your contract rate plus two percentage points, or 5.25 percent. If the Office of the Superintendent of Financial Institutions changes that floor mid-search, your pre-approval amount can shrink without your finances changing at all. The rate hold protects your rate. It does not protect your qualifying amount.
Where the property kills the deal
The borrower is only half the equation. The lender also approves the asset, and that happens after you have an accepted offer. If the bank's appraiser values the Saanich bungalow at $800,000 instead of your $840,000 purchase price, you now have a $40,000 gap to fill in cash. Your pre-approval said nothing about this because the appraisal had not happened yet.
Older homes on Vancouver Island surface other problems. An unpermitted suite, an aging oil tank, a strata with a history of special assessments, any of these can make a property ineligible for financing even when your credit and income are perfect. The pre-approval was based on a theoretical property that met standard lending criteria. The actual property might not.
This is why waiving the financing condition in a competitive Victoria market is a bet, not a formality. The three-business-day rescission period under BC's Home Buyer Rescission Period gives you an escape hatch, but using it costs you 0.25 percent of the purchase price. On an $840,000 home, that's $2,100 to walk away from a deal your pre-approval suggested was safe.
The borrower-side failures
Changes in your debt load between pre-approval and closing will reduce what the lender will actually fund. Financing a car, opening a line of credit, even a large credit card balance that wasn't there when you were pre-approved, all of these shift your debt-to-income ratio, and the final underwriting will catch it.
Pre-approvals are typically valid for 90 to 120 days. If your search runs longer, you will need to renew, and renewal is not automatic. The lender will re-pull your credit. If your score has dropped or your employment situation has changed, the pre-approval can shrink or disappear entirely.
The structure of the financing process means the real approval happens after you have committed to the purchase. The pre-approval is not a safety net. It is a weather report, and the weather can shift.
