Mortgage Pre-Approval: What It Is and How to Get One

A mortgage pre-approval tells you roughly how much a lender would lend and often holds a rate for a set period. It is a planning tool, not a final approval.

What a mortgage pre-approval is

A pre-approval is an early assessment of your mortgage application. The lender reviews your income, debts, credit history and down payment, then estimates the amount it would be willing to lend and the rate it would offer. Many lenders hold that rate for a set period, commonly 90 to 120 days, so you can shop for a home without watching rates move against you.

The purpose is to turn an abstract budget into a realistic price range. Instead of guessing what you can afford, you walk into viewings with a number a lender has already vetted. That makes your offer stronger and your search more focused. It also gives you time to line up a down payment and save for closing costs while you shop, and it signals to sellers that your financing is already in motion.

Pre-approval vs pre-qualification

The two terms are often used interchangeably, but they are not the same thing. A pre-qualification is a lighter check, sometimes based only on numbers you provide, and it usually involves a soft credit inquiry. A pre-approval goes deeper, verifies your documents and typically involves a hard credit inquiry that may affect your credit score.

What the lender reviews

The lender wants to confirm three things: that you can repay, that your down payment is genuine, and that you are who you say you are. Income is checked through pay stubs, employment letters or tax documents. Existing debts are pulled from your credit report. Down payment funds are traced to their source, which is why a sudden large deposit can raise questions if you cannot explain it.

Under OSFI Guideline B-20, federally regulated lenders must also qualify you at a minimum qualifying rate, the greater of your contract rate plus two percentage points or 5.25%. That stress test often means the amount you are pre-approved for is lower than the amount you might have expected from a simple income multiple.

The rate hold

A rate hold protects you if rates rise during the hold period. If rates fall, most lenders will offer the lower rate available at the time of closing, though the exact terms vary. Read the hold conditions carefully. Some holds apply only to specific terms or rate types, and some expire on a fixed date regardless of when you find a home.

Documents to gather

Having your paperwork ready speeds up the process and reduces back and forth.

• Government-issued photo identification
• Recent pay stubs and a letter of employment, or tax returns and notices of assessment if you are self-employed
• Bank and investment statements showing your down payment and closing funds
• Details of existing loans, credit cards and lines of credit
• If you are new to Canada, documents confirming your status and income history
• For a gifted down payment, a signed letter from the person providing the funds

Step by step through the process

1. Check your credit report and correct any errors before you apply.
2. Gather your income, identity and down payment documents.
3. Decide on a term and rate type you are comfortable with, or ask a professional to explain the options.
4. Submit the application and authorize the credit check.
5. Review the pre-approval amount, rate and hold period in writing.
6. Shop for a home within the range you were given.
7. Return to the lender with the property details for final approval.

What a pre-approval does not guarantee

A pre-approval is not a promise to lend. Final approval depends on the property passing an appraisal, on your financial situation staying the same, and on the lender confirming the details you provided. A job loss, a new car loan or a large credit card balance taken on after the pre-approval can change the outcome.

This is why you should avoid major financial changes between pre-approval and closing. Do not change jobs, finance a vehicle or open new credit accounts if you can avoid it. Lenders often recheck your file before funding.

After you are pre-approved

Once you have an accepted offer, the lender appraises the property to confirm it is worth the price you agreed to pay. Then the file goes to final underwriting, where your documents are verified once more. If everything holds, you receive a commitment letter setting out the rate, term, payment and conditions. Read it before you sign, because it is the document that governs your mortgage.

Protecting your personal information

A mortgage application involves sensitive personal and financial data. In Canada, PIPEDA governs how private-sector organizations handle that information, including how it is collected, used and safeguarded. Ask how your documents will be stored and who will see them, and share them only with parties you trust.

Making pre-approval work for you

A pre-approval is most useful when you treat it as a starting point rather than a finish line. Use it to set a price ceiling you can genuinely afford, not just the ceiling a lender allows. Leave room in your budget for closing costs and for the possibility that rates at renewal differ from the rate you start with. Promissory.ca is not a lender or a mortgage broker and charges consumers no fee; it may receive compensation from lending partners. A licensed mortgage professional can guide you through the application and explain your options.

What to do if you are declined for pre-approval

A decline is not the end of the process. It usually points to something specific that can be addressed. The most common causes are a debt-service ratio that is too high, an insufficient or unverifiable down payment, a short employment history, or a credit file with recent missed payments.

Ask the lender or mortgage professional what drove the decision. If the issue is debt service, paying down a revolving balance can change the maths quickly because it lowers both the balance and the minimum payment. If the issue is the down payment, a longer savings period may be the answer. If the issue is credit, focus on on-time payments and lower utilization before reapplying, and avoid submitting multiple applications in a short period.

It also helps to understand the difference between a pre-approval and an approval. A pre-approval is an indication of what a lender is prepared to lend based on the information you provide, subject to verification. The final approval depends on the property, the appraisal and a full document review. Treat a pre-approval as a planning tool, not a guarantee.
