Buying your first home is one of the biggest financial decisions you will ever make. While homeownership is exciting, many first-time home buyers in Ontario make common mistakes that can cost thousands of dollars or create unnecessary stress during the buying process.
Whether you’re purchasing a condo in Toronto, a townhouse in Mississauga, or a detached home in Brampton, avoiding these mistakes can save you time, money, and frustration.
In this guide, I’ll walk you through the top five mistakes first-time home buyers make in Ontario and how you can avoid them.
Mistake #1: Getting Pre-Qualified Instead of Pre-Approved
Many first-time buyers believe that being pre-qualified means they are ready to purchase a home. Unfortunately, this is one of the most common misunderstandings in real estate.
A mortgage pre-qualification is simply an estimate based on information you provide to a lender. It does not guarantee mortgage approval.
Why This Is a Problem
You may find your dream home, submit an offer, and later discover that your actual mortgage approval is lower than expected. That can mean losing the property, scrambling to find more down payment, or backing out of the deal entirely.
How to Avoid It
Before starting your home search, obtain a full mortgage pre-approval that includes:
- Verification of income (pay stubs, T4s, tax returns)
- Credit check and credit history review
- Employment confirmation
- Down payment verification (bank statements, gift letters)
- Rate hold for 90–120 days
A pre-approval gives you a realistic budget and strengthens your offer when competing against other buyers. Sellers and their agents take pre-approved buyers more seriously because the financing risk is significantly lower.
Mistake #2: Shopping at the Maximum Budget
Just because a lender approves you for a certain amount doesn’t mean you should spend it all.
Many buyers focus on the highest price they qualify for without considering future expenses, interest rate changes, maintenance costs, or unexpected repairs. When I work with first-time buyers, I always remind them: the bank’s maximum isn’t necessarily your maximum.
Why This Is a Problem
Purchasing at the top of your budget can leave little room for financial flexibility. If interest rates rise at renewal, property taxes increase, or you face a major repair (like a new furnace or roof), you may find yourself financially stretched.
How to Avoid It
A smart strategy is to search for homes that are 10% to 15% below your maximum approval amount. Use a mortgage calculator to model different purchase prices and see what your monthly payments would look like at various interest rates.
This provides breathing room for:
- Property taxes (which can be $3,000–$6,000+ annually depending on location)
- Utility costs (heat, electricity, water, internet)
- Maintenance expenses (1–2% of home value per year is a good rule of thumb)
- Future rate increases at renewal
- Emergency repairs (HVAC, plumbing, appliances)
Remember, financial comfort is often more important than buying the most expensive home possible. You want to enjoy your home, not feel house-poor.
Mistake #3: Skipping the Home Inspection
In competitive real estate markets, some buyers waive the home inspection condition to make their offer more attractive. I’ve seen this happen frequently in bidding wars across the GTA, especially in hot neighbourhoods.
While this may help win a bidding war, it can also expose buyers to significant risks.
Why This Is a Problem
Hidden issues can include:
- Foundation cracks or structural problems
- Roof damage or aging shingles nearing replacement
- Electrical deficiencies (outdated panels, aluminum wiring)
- Plumbing issues (polybutylene pipes, leaks, poor drainage)
- Water penetration in the basement or crawl space
- Mold, insulation concerns, or HVAC system failures
These repairs can cost thousands—sometimes tens of thousands—of dollars after closing. I’ve seen buyers discover $15,000–$30,000 in immediate repairs within weeks of taking possession.
How to Avoid It
Whenever possible:
- Include a home inspection condition in your offer (typically 5–7 days).
- Conduct a pre-offer inspection if you’re competing in a multiple-offer situation and want to waive conditions confidently.
- Review the inspector’s report carefully before proceeding—don’t just skim the summary.
A few hundred dollars spent on an inspection can save you tens of thousands in unexpected repairs. It’s one of the best investments you can make as a buyer.
Mistake #4: Falling in Love with a Home Before Reviewing Comparable Sales
Buying a home is an emotional experience, but successful buyers rely on data, not emotions.
Many first-time buyers become emotionally attached to a property—they imagine their furniture in the living room, picture hosting friends in the backyard—and end up overpaying because they “just have to have it.”
Why This Is a Problem
Without reviewing recent comparable sales, you may pay significantly more than the property’s actual market value. Overpaying by even 5–10% can cost you $30,000–$60,000 on a $600,000 home—money that could have gone toward renovations, furniture, or your emergency fund.
How to Avoid It
Before submitting an offer, review:
- Recent sold properties in the same neighbourhood (ideally within the last 60–90 days)
- Comparable homes with similar size, age, and features
- Market trends (Are prices rising, stable, or softening?)
- Days on market (Homes sitting longer may indicate overpricing)
- Current competition (How many similar homes are available?)
An experienced real estate professional can provide a Comparative Market Analysis (CMA) to help determine a fair market value. I always prepare a detailed CMA for my buyers so they can make informed, confident decisions—not emotional ones they might regret later.
Mistake #5: Forgetting About Closing Costs
Many buyers save diligently for the down payment but overlook the additional expenses required on closing day. This is one of the most common surprises I see with first-time buyers.
Common Closing Costs in Ontario
- Land Transfer Tax (provincial, plus municipal in Toronto)
- Legal Fees ($1,500–$2,500 including disbursements)
- Title Insurance ($200–$400)
- Home Inspection Fees ($400–$600)
- Appraisal Fees (if required by lender, $300–$500)
- Moving Costs ($500–$2,000+ depending on distance and volume)
- Utility Setup Costs (deposits, connection fees)
- Property Tax Adjustments (reimbursing the seller for prepaid taxes)
Why This Is a Problem
Unexpected closing costs can create financial stress just weeks before possession. Some buyers end up scrambling to borrow from family, dip into emergency savings, or delay their move.
How to Avoid It
A good rule of thumb is to budget an additional 3% to 5% of the purchase price for closing costs. On a $600,000 home, that’s $18,000–$30,000. Use a closing cost calculator to estimate your total expenses early in the process.
First-time buyers in Ontario may also qualify for:
- Ontario Land Transfer Tax Rebate (up to $4,000)
- Toronto Land Transfer Tax Rebate (up to $4,475 for Toronto purchases)
- First Home Savings Account (FHSA) benefits (tax-free withdrawals for first-time buyers)
- Home Buyers’ Plan (HBP) (borrow up to $35,000 from your RRSP tax-free)
You can learn more about land transfer tax and rebates using the Ontario Land Transfer Tax calculator. Consult your realtor, lawyer, and mortgage professional to understand your total costs before making an offer.

Frequently Asked Questions
How much down payment do first-time home buyers need in Ontario?
The minimum down payment is 5% for homes up to $500,000. For homes between $500,000 and $999,999, you need 5% on the first $500,000 and 10% on the remaining amount. For homes $1 million or more, you need a minimum 20% down payment. First-time buyers can also use the First Home Savings Account (FHSA) and Home Buyers’ Plan (HBP) to access tax-advantaged funds for their down payment.
What credit score is needed to buy a house in Ontario?
Most lenders prefer a credit score of 680 or higher for the best mortgage rates and terms. Some programs may allow lower scores (as low as 600 in certain cases), but you may face higher interest rates or require mortgage default insurance. It’s a good idea to check your credit score early and address any issues before applying for a mortgage.
How much should I budget for closing costs in Ontario?
Typically between 3% and 5% of the purchase price. This includes land transfer tax, legal fees, title insurance, home inspection, appraisal, moving costs, and utility setup. First-time buyers in Ontario can claim a land transfer tax rebate of up to $4,000 (or up to $4,475 in Toronto), which helps offset some of these costs.
Should I get a home inspection even in a competitive market?
Yes. A home inspection helps identify potential issues before you commit to the purchase, protecting you from costly surprises after closing. If you’re in a competitive multiple-offer situation, consider a pre-offer inspection so you can waive the condition confidently. Skipping the inspection entirely is risky and can lead to tens of thousands of dollars in unexpected repairs.
What is the difference between pre-qualification and pre-approval?
Pre-qualification is an estimate based on basic financial information you provide, without verification. Pre-approval is a lender-reviewed mortgage commitment based on verified income, credit check, employment confirmation, and down payment verification. A pre-approval gives you a realistic budget, strengthens your offer, and includes a rate hold for 90–120 days, making it far more valuable than a pre-qualification.
