When To Get a Mortgage Pre-Approval?
What is a mortgage pre-approval?
A mortgage pre-approval is when a lender or mortgage professional reviews your financial information before you buy a home.
They may look at your income, down payment, credit, debts, and documents to estimate how much mortgage you may qualify for.
It is not always a final approval, but it can give you a clearer starting point.
When should you get pre-approved?
You should usually get a mortgage pre-approval before viewing homes seriously or making offers.
This is especially helpful if you are buying in Ontario, where home prices can vary widely between cities and neighbourhoods.
If you are close to making offers, booking showings, or comparing homes online, it is probably time to get pre-approved.
Why pre-approval matters before house shopping
A pre-approval can help you avoid guessing.
It may help you understand:
- Your estimated purchase price range
- Your possible mortgage amount
- Your monthly mortgage payment
- Whether your down payment is enough
- What documents you may need
Before applying, you can test different prices using the Mortgage Payment Calculator.
Does pre-approval mean you are fully approved?
No. This is an important mortgage myth.
A pre-approval does not always guarantee final mortgage approval.
Final approval usually depends on:
- The property you buy
- Your final documents
- Your income staying the same
- Your debt staying the same
- The lender’s full review
Should you calculate your payment before pre-approval?
Yes. A pre-approval may tell you what you could qualify for, but a calculator helps you understand what payment feels comfortable.
Those are not always the same thing.
What should you check before applying?
Before getting pre-approved, it helps to review:
- Your income
- Your down payment
- Your monthly debts
- Your credit situation
- Your estimated closing costs
You can also estimate upfront buying costs using the Closing Costs and Land Transfer Tax Calculator.
What if your budget changes?
Your pre-approval amount can change if your income, debts, credit, interest rates, or down payment changes.
This is why it helps to compare different numbers before you buy.
You can compare two possible purchase scenarios using the Dual Scenario Mortgage Calculator.
Simple summary
You should usually get a mortgage pre-approval before seriously shopping for homes or making offers.
A pre-approval helps you understand your buying range, but calculators help you understand your real monthly comfort zone.
