Buying your first home is exciting, expensive, and full of unfamiliar decisions — which makes it easy to slip up in ways that cost real money. The good news is that the most common first-time buyer mistakes are also the most preventable. Here are nine to watch for, and how to avoid each one.
- Forgetting closing costs (1.5%–4% of the price) is the most common budgeting mistake.
- Shopping before a pre-approval wastes time and weakens your offers.
- Skipping first-time buyer programs leaves tens of thousands of dollars on the table.
- Maxing out your budget ignores the stress test and leaves no cushion for rate changes.
- Waiving conditions like inspection and financing to win a bid can backfire badly.
Money and budgeting mistakes
The most painful mistakes are the financial ones, because they're hard to undo. Three stand out for first-time buyers:
- Forgetting closing costs. Beyond your down payment, budget 1.5%–4% of the price for land transfer tax, legal fees, title insurance and more. See closing costs in Ontario.
- Maxing out your budget. Just because you qualify for an amount doesn't mean you should spend it. Leave room for rate increases and life's surprises.
- Ignoring the stress test. You must qualify at the greater of your contract rate + 2% or 5.25% — plan around that, not just today's rate.
Process and timing mistakes
How you sequence the buying process matters as much as the numbers. These missteps slow you down or weaken your position:
- House-hunting before a pre-approval. Without one, you don't know your real budget — and sellers take your offer less seriously.
- Confusing pre-qualification with pre-approval. They're not the same. Learn the difference in pre-approval vs pre-qualification.
- Opening new credit before closing. A new car loan or credit card mid-purchase can derail your mortgage approval.
Leaving free money on the table
First-time buyers in Ontario have access to several programs worth tens of thousands of dollars combined. Not using them is one of the costliest oversights.
| Program | Worth |
|---|---|
| FHSA | Save up to $40,000, tax-free |
| RRSP Home Buyers' Plan | Up to $60,000 tax-free |
| Ontario LTT rebate | Up to $4,000 |
| Toronto LTT rebate | Up to $4,475 |
| GST rebate (new homes) | Up to $50,000 |
Mistake #7: skipping these incentives. See the full list in first-time home buyer programs in Canada and the new-build GST rebate.
Due-diligence mistakes
The final two mistakes happen at the offer stage, when emotions run high and competition is fierce:
- Waiving conditions to win. Dropping financing or inspection conditions can win a bidding war — and leave you stuck with a home you can't finance or that has hidden problems.
- Skipping the home inspection. An inspection costs $300–$600 and can reveal issues worth many times that. It's cheap insurance on the biggest purchase of your life.
