Key takeaways
- Pre-qualification is a rough estimate. Pre-approval is a lender's review of your documents. Final approval comes after you have a property.
- A pre-approval is not a guarantee of financing.
- Many pre-approvals hold a rate for a limited period. Ask how long.
- Avoid new debt between pre-approval and closing.
These terms get mixed up. Knowing the difference helps you make offers with confidence.
Pre-qualification
A quick estimate based on what you tell a lender or broker about your income, debts and down payment. It's useful for early planning, but nothing is verified.
Pre-approval
A lender reviews your documents and credit and says, in principle, how much you may be able to borrow, often with a rate hold for a limited time (many are 90 to 120 days, but it varies). It tells you your likely budget before you shop.
A pre-approval is not a guarantee. The lender still has to approve the property and verify your information at the final stage, and your situation needs to stay the same.
Final approval
Once you have an accepted offer, the lender reviews the property (sometimes with an appraisal) and your updated documents, then issues the final approval and commitment. Conditions in your offer, such as financing, are usually removed after this step.
What lenders typically ask for
- Photo ID and your SIN (provided securely, never by email or website form)
- Proof of income (employment letter and pay stubs, or tax documents if self-employed)
- Down payment history (about 90 days of statements)
- Details of debts and a credit check
Protect your approval
- Don't take on new debt or financing (car, furniture, cards) before closing.
- Keep your job and income stable if you can.
- Don't move large sums around without a paper trail.
- Tell your mortgage professional about any changes.
Does applying affect your credit? Lenders typically check your credit when you apply, which can show as an inquiry. We'll explain what to expect before you apply. See how credit affects your mortgage.
