Every year, thousands of Quebecers take the leap into homeownership for the first time. According to OACIQ and CMHC data, the most common mistakes cost first-time buyers an average of $15,000 to $45,000. This guide identifies the seven most costly errors and gives you concrete tools to avoid them in 2026. With a rising real estate market and interest rates that remain attractive, preparation is your best ally.
Mistake #1: Underestimating Closing Costs
Most first-time buyers focus solely on the down payment and the monthly mortgage payment. However, for a $450,000 purchase, closing costs total between $12,000 and $19,000. Without adequate preparation, these additional expenses can jeopardize your entire purchase project.
Cost breakdown for a $450,000 purchase
- Welcome tax (transfer duties): $5,250
- Notary fees: $1,500 – $2,500
- Pre-purchase inspection: $500 – $800
- Certificate of location: $1,000 – $2,000
- Title insurance: $300 – $500
- Municipal tax adjustments: $1,000 – $3,000
- Moving and minor repairs: $2,000 – $5,000
- Home insurance (first year): $800 – $1,500
Solution: Set aside a cushion of 3 to 5% of the purchase price to cover all closing costs. For a $450,000 purchase, that means $13,500 to $22,500 on top of your down payment. A mortgage broker can help you budget these amounts precisely.
Mistake #2: Skipping Mortgage Pre-Approval
Visiting properties without mortgage pre-approval is one of the most frequent mistakes. Pre-approval gives you three major advantages: it locks in an interest rate for 90 to 120 days, precisely defines your maximum budget, and significantly strengthens your purchase offer in the seller’s eyes.
Potential cost: Without pre-approval, a 0.25% rate increase on a $400,000 loan over 25 years costs $12,000 in additional interest. A financing denial after an accepted offer can also result in losing your deposit.
Solution: Get your pre-approval before starting visits. The process typically takes 24 to 48 hours and costs nothing. A mortgage broker can shop the best rates for you across multiple financial institutions.
Mistake #3: Skipping the Pre-Purchase Inspection
In a competitive market, some buyers waive the pre-purchase inspection to make their offer more attractive. This decision can be extremely costly. According to CMHC, undetected hidden defects cost homeowners an average of $20,000 to $80,000. The most common problems include cracked foundations, end-of-life roofing, defective plumbing and water infiltration issues.
OACIQ strongly recommends pre-purchase inspection, even though it is not legally mandatory. A certified inspector can detect major problems invisible to the naked eye and save you considerable expenses after the purchase.
Solution: Always include an inspection condition in your offer. The cost of an inspection ($500 to $800) is minimal compared to the risks. If the market is highly competitive, consider a pre-inspection before submitting your offer.
Mistake #4: Ignoring the FHSA and HBP
Not using government homeownership programs is a mistake that can cost up to $48,000 in missed savings. The FHSA (First Home Savings Account) allows contributions of up to $40,000 lifetime with tax-deductible contributions and tax-free withdrawals. The HBP (Home Buyers’ Plan) allows withdrawing up to $60,000 from your RRSP without immediate taxation.
Potential savings (per person)
- FHSA: $40,000 + returns + tax savings of $8,000 to $16,000
- HBP: $60,000 withdrawn from RRSP tax-free
- Couple: up to $200,000 mobilized for the down payment
Solution: Open an FHSA as soon as possible, even with a small amount. Contribute to your RRSP in anticipation of the HBP. Consult a financial planner to maximize the use of both programs.
Mistake #5: Making an Unconditional Offer
Facing the pressure of multiple offers, many first-time buyers remove all conditions from their purchase offer. The three essential conditions to protect are: the financing condition, the inspection condition and the title verification condition. Removing these protections exposes the buyer to major financial risks. A denied financing without a suspensive condition can result in losing your deposit of $5,000 to $25,000.
Solution: Discuss with your real estate broker the minimum conditions to maintain. An experienced broker can structure your offer to be competitive while preserving essential protections. Short deadlines (48 to 72 hours) for fulfilling conditions can make your offer more attractive without exposing you to risk.
Mistake #6: Neglecting Title Insurance
Title insurance protects against defects related to the title of ownership: encroachments, undisclosed easements, real estate fraud, errors in the chain of titles or unpaid municipal taxes. Without this protection, a title defect can cost between $5,000 and $50,000 in legal fees and loss of value. The cost of title insurance is modest: between $300 and $500 for lifetime protection.
Solution: Ask your notary to explain the benefits of title insurance. For an older property or a complex legal situation, this protection is particularly recommended. It is a minimal investment that can spare you considerable expenses.
Mistake #7: Buying Without a Real Estate Broker
A real estate broker is paid by the seller in the vast majority of transactions in Quebec. As a buyer, you benefit from the expertise of a professional at no direct cost. The broker negotiates on your behalf, verifies document compliance, identifies potential problems and guides you through each step of the transaction. According to OACIQ, buyers accompanied by a broker generally obtain a better price than those who buy alone.
Solution: Engage a real estate broker from the start of your project. A good broker knows the local market, has access to exclusive properties and can save you thousands of dollars in negotiation. On CourtiConnect, find a broker specializing in first-time buyers in your area.
