7-item pre-approval checklist for Mississauga homebuyers

Before you start: what mortgage pre-approval means in Ontario

Mortgage pre-approval is a lender's conditional estimate of how much you can borrow based on the information you provide. It helps you set a realistic price range, strengthens offers, and speeds up closing when you find a home. Lenders mainly check your income, credit history, down payment source, and monthly debts to calculate qualifying ratios. For a practical overview of documents lenders commonly request and rules for insured mortgages, see the CMHC homebuying checklist for Canada. CMHC homebuying checklist.

If you want to shop multiple lenders or need help preparing complex documentation, a licensed mortgage broker in Mississauga can save time and present options you might miss. MiiGrowth is a local FSRA-licensed brokerage with tools such as Instant Eligibility and affordability calculators to help you prepare. MiiGrowth.

1. 1) Proof of income and employment

   What to prepare: recent pay stubs (last two to four pay periods), T4 slips for the most recent tax year, an employer letter confirming position and salary, and your most recent Notice of Assessment (NOA) from the CRA. If you receive commissions, bonuses, or other variable pay, include year-to-date statements and historical pay records.

   Why lenders check this: lenders verify stable, sustainable income to estimate qualifying capacity. They commonly use gross income when calculating qualifying ratios and will treat variable pay differently from base salary.

   Common mistakes: providing only one pay stub, omitting NOAs, or failing to explain variable pay. If you are starting a new job, notify your broker or lender early because start letters are handled differently.

   Practical next step: gather digital copies of pay stubs and NOAs, then run an Instant Eligibility check with your broker to get an early estimate of qualifying income. MiiGrowth.

2. 2) Down payment and proof of source

   What to prepare: bank statements showing savings accumulation, documentation for registered plans used under the Home Buyers' Plan if applicable, sale-of-assets paperwork, and a signed gift letter with the donor's ID if part of the down payment is a gift. Insurers and lenders require clear proof of down payment source for insured high-ratio mortgages. CMHC homebuying checklist.

   Why lenders check this: lenders must confirm your down payment is legitimate and not borrowed in a way that increases your overall debt burden. Large unexplained deposits are a common red flag and will delay processing.

   Common mistakes: moving large sums between accounts without documentation, relying on undocumented private loans, or failing to provide a properly signed gift letter. For registered-fund withdrawals, bring confirmation of the withdrawal and any program paperwork.

   Practical next step: collect two to three months of bank statements and any gift documentation, and coordinate deposit timing with your broker before making an offer in Mississauga.

3. 3) Credit report, identification, and credit-use details

   What to prepare: government photo ID, Social Insurance Number for identity verification, and a summary of outstanding credit accounts from online banking or statements. Authorize your lender or broker to pull a fresh credit report so they can see payment history, score range, and recent inquiries.

   Why lenders check this: payment history, credit utilisation, and recent credit inquiries affect risk assessment and the programs or rates offered. High balances and recent new accounts can reduce your qualifying amount.

   Common mistakes: applying for new credit before or during pre-approval, co-signing a loan without notifying your broker, and ignoring errors on your credit file. If you find mistakes, obtain a corrected report and notify your broker immediately.

   Practical next step: avoid new credit applications until after closing and give your broker permission to obtain your credit report for the most accurate assessment.

4. 4) Assets, liabilities and monthly expense breakdown

   What to prepare: recent bank statements for all accounts, investment statements, current balances and payment schedules for vehicle loans, student loans, lines of credit, and credit cards, and documentation for recurring obligations such as child support. Provide clear monthly payment amounts and outstanding balances.

   Why lenders check this: lenders calculate Gross Debt Service (GDS) and Total Debt Service (TDS) ratios to determine affordability. Those ratios compare your shelter costs and total monthly debts to your gross income and help set maximum qualifying amounts.

   Common mistakes: forgetting informal payments, underestimating monthly expenses, or uploading only partial statements. Omitting liabilities can move a file from approved to declined when the full picture is revealed.

   Practical next step: create one consolidated list of monthly payments and upload full statements for the last two to three months so your broker can calculate GDS and TDS accurately.

5. 5) Property plan or purchase details

   What to prepare: the MLS listing or draft purchase agreement, the seller's asking price, planned down payment and deposit amount, condominium status and condo documents if applicable, and the intended property use such as primary residence or rental. Lenders need a realistic purchase price and confirmation of property type for accurate underwriting.

   Why lenders check this: mortgage programs and maximum loan amounts vary by property type and occupancy. Insured high-ratio mortgages have particular rules for owner-occupied versus investment properties. CMHC homebuying checklist.

   Common mistakes: requesting pre-approval without a target price or asking for an amount beyond typical lending limits for the property type. Investors should expect higher qualifying standards and larger down payment requirements.

   Practical next step: save MLS links or screenshots and share them with your broker so the pre-approval is tailored to the property and occupancy type.

6. 6) Self-employed and alternative income documentation

   What to prepare: personal and business tax returns (T1 general) and Notices of Assessment for the past two to three years, corporate financial statements if you operate through a corporation, HST/GST remittances when relevant, business bank statements, and contracts or invoices that demonstrate revenue stability. Lenders commonly average self-employed income over two or more years to determine qualifying income.

   Why lenders check this: self-employed income is often variable, so lenders require more documentation to confirm consistent earnings and to detect one-off spikes. Clear multi-year documentation reduces surprises.

   Common mistakes: submitting only one year of tax returns, omitting corporate paperwork when income flows through a company, or failing to document owner draws. These gaps can lead to a lower qualifying amount or requests for further documents.

   Practical next step: compile two to three years of NOAs and business statements and speak with a broker experienced with self-employed files. MiiGrowth assists Southern Ontario self-employed clients with lender options tailored to alternative income documentation. MiiGrowth.

7. 7) Special cases: investors, refinances, renewals and mortgage insurance

   What to prepare: for investors bring rent rolls, lease agreements, and two years of owner tax returns. For refinance or renewal requests provide current mortgage statements, details of the reason for refinancing such as debt consolidation or renovations, and documentation for planned additional borrowing. For insured mortgages, be ready to confirm down payment source and meet insurer requirements. For insurer and program rules see the CMHC homebuying checklist. CMHC homebuying checklist.

   Why lenders check this: investor loans, refinances and renewals often trigger closer scrutiny of cash flow, rental income sustainability, and loan-to-value ratios. Program steps vary by lender and property purpose.

   Common mistakes: using optimistic rental income assumptions, under-documenting renovation costs for refinance projects, or assuming a renewal will automatically yield a lower rate. In special cases a broker can find lenders with flexible underwriting or alternative programs that better match your situation.

   Practical next step: gather leases, current mortgage statements, and a clear refinancing plan, and contact a broker early so you can compare lender options instead of relying on one path.

After pre-approval: what to expect and next steps

Once you have a pre-approval, confirm its expiry date and conditions. Typical pre-approvals have an expiry period and are conditional on documents remaining accurate. If your financial situation changes or you plan to make large purchases before closing, update your broker. Use your pre-approval to make competitive offers and coordinate financing deadlines in the purchase agreement. For additional document guidance and insured mortgage rules consult the CMHC homebuying checklist. CMHC homebuying checklist.
