Getting pre-approved feels like the finish line, you have a number, a rate, maybe even a letter from the bank. But pre-approval and final approval aren’t the same thing, and I talk to buyers every month who are surprised to learn what pre-approval actually covers, and what it doesn’t. Here’s the real breakdown.
Pre-Qualification and Pre-Approval Aren’t the Same Thing
These two terms get used interchangeably, but they’re different steps. Pre-qualification is an informal estimate based on what you tell the lender, no credit check, no documents, no commitment. Pre-approval is the real version: the lender pulls your credit, reviews your income and debts, and gives you a written commitment for a maximum mortgage amount and an interest rate. If you’re actually house-hunting, pre-approval is the one you want, pre-qualification is just a rough starting point.
What Pre-Approval Actually Guarantees (and What It Doesn’t)
A pre-approval is not a guarantee you’ll get the loan. It tells you, and any seller you make an offer to, roughly what you can borrow and at what rate. Final approval still depends on a full underwriting review, an appraisal of the specific property you’re buying, and your financial situation staying the same between pre-approval and closing. The lender is qualifying you in general, not yet qualifying you for the exact home you end up buying.
Can You Still Be Denied After Being Pre-Approved?
Yes, and it happens more often than buyers expect. The most common reasons: taking on new debt (a car loan, a new credit card) during the pre-approval window, a job change or income drop, a credit score that slips before closing, or the property itself appraising lower than the purchase price. A title search turning up a lien on the property can also stall things. None of this is common if your situation stays stable, but it’s exactly why I tell buyers not to make any big financial moves, new credit, a new car, a job switch, between pre-approval and closing day.
How Long Does It Take, and How Long Is It Good For?
Getting pre-approved usually takes one to three business days once your documents are in, sometimes same-day if everything’s straightforward. Once you have it, it’s typically valid for 90 to 120 days (some lenders go up to 130), and it locks in your interest rate for that window. If rates go up before you close, you keep your locked rate. If rates drop, most lenders will let you switch to the lower one. If you don’t close within the window, you’ll need to redo it against whatever rates are current at that point.
Does Getting Pre-Approved Hurt Your Credit?
A little, but not in a way that should stop you. Pre-approval requires a hard credit inquiry, which typically dips your score by a few points, small and temporary. If you’re comparing lenders, apply within the same 14-to-45-day window, credit bureaus in Canada treat multiple mortgage inquiries in that window as a single inquiry, so rate-shopping doesn’t multiply the impact.
Getting Pre-Approved the Right Way
The paperwork is usually the slow part: pay stubs, an employment letter, your last two years of Notices of Assessment, bank statements for your down payment, and a signed credit check authorization. I walk buyers through exactly what their lender will ask for before they apply, so there’s no back-and-forth scrambling for documents once you’re ready to move.

Frequently Asked Questions About Mortgage Pre-Approval
Does pre-approval mean I will get the loan?
No. Pre-approval gives you a written estimate of what you can borrow and at what rate, but final approval still requires a full underwriting review, an appraisal of the specific home you’re buying, and no material change to your financial situation before closing.
Can you be denied a mortgage after pre-approval?
Yes. The most common reasons are new debt taken on after pre-approval, a job or income change, a drop in credit score, or the property appraising lower than the purchase price. Keeping your finances steady between pre-approval and closing is the best way to avoid this.
How long does a mortgage pre-approval last in Ontario?
Most lenders hold a pre-approval, including your locked interest rate, for 90 to 120 days, with some going up to 130. If you don’t close within that window, you’ll need to redo the pre-approval based on current rates.
Does mortgage pre-approval affect your credit score?
Slightly. It requires a hard credit inquiry, which typically causes a small, temporary dip. If you apply with multiple lenders within a 14-to-45-day window to compare rates, Canadian credit bureaus count those as a single inquiry, so shopping around doesn’t compound the impact.
