Buying your first home is one of the biggest financial decisions you'll ever make, and most of the stress around it comes from not knowing what order things actually happen in. This is the complete, current guide — every step, in order, with the real 2026 numbers for qualifying, budgeting and closing, across London, St. Thomas and the Kitchener-Waterloo-Cambridge triangle.

548 490 4577The step-by-step process
| Step | What Happens | Why It Matters |
|---|---|---|
| 1. Check your credit | Pull your credit report and score before doing anything else | A higher score can mean a meaningfully better rate and access to more lenders |
| 2. Get pre-approved | A mortgage broker or lender confirms what you actually qualify for | You shop with a real number instead of a guess, and sellers take your offer seriously |
| 3. Budget beyond the down payment | Add closing costs, moving costs, and ongoing carrying costs | The down payment is rarely the only number that matters |
| 4. House hunt with a buyer's agent | Tour homes, compare pockets, narrow down what actually fits | A seller's agent doesn't represent your interests — your own agent does |
| 5. Make an offer | Price, conditions (financing, inspection), and closing date, submitted together | The terms matter as much as the price in a competitive situation |
| 6. Home inspection | A licensed inspector checks the property's condition | Catches costly problems before they become your problem |
| 7. Finalize financing | Your lender confirms the mortgage based on the accepted offer | The last checkpoint before you're financially committed |
| 8. Close with a lawyer | Funds transfer, documents sign, keys change hands | Typically 30–90 days after your offer is accepted |
How much do you actually need to qualify?
This is where a lot of first-time buyer advice online is out of date. Here's what actually applies in 2026:
- Minimum down payment: 5% on the first $500,000 of the purchase price, and 10% on the portion between $500,000 and $1.5 million
- Mortgage stress test: you need to qualify at either your contract rate plus 2%, or 5.25%, whichever is higher — not the rate you'll actually pay
- GDS (Gross Debt Service): your housing costs — mortgage, property tax, heating, half of any condo fees — generally can't exceed 39% of your gross income
- TDS (Total Debt Service): GDS plus all other debt payments generally can't exceed 44% of your gross income
- CMHC mortgage default insurance is required on any purchase with less than 20% down, and is required by law on homes up to $1.5 million
The 30-year amortization change most guides haven't caught up to
As of the federal government's 2024 expansion, first-time buyers can now access 30-year amortizations on insured mortgages (under 20% down) on both new and resale homes — not just new construction, which was the original, narrower rule. Stretching payments over 30 years instead of 25 lowers your monthly payment, which directly lowers your GDS and TDS ratios and can meaningfully change what you qualify for. Confirm current eligibility with your mortgage broker, since program details are periodically reviewed.
Credit score: what actually moves the needle
In Canada, a score above 660 generally opens up mainstream lender options, and above 700 typically gets you the best available rates — but the score itself is only part of the picture; lenders also weigh your income stability and existing debt load. The single biggest mistake at this stage: taking on new debt (a car loan, a new credit card, financing furniture) between your pre-approval and your closing date. That can change your qualifying numbers enough to jeopardize financing you already thought was locked in.
Budgeting beyond the purchase price
Closing costs in Ontario typically run 1.5% to 4% of the purchase price — legal fees, title insurance, home inspection, and land transfer tax, though first-time buyers get a provincial land transfer tax refund of up to $4,000. On a $500,000 home, budget realistically for $7,500 to $20,000 in closing costs on top of your down payment. My full closing costs checklist breaks down every line item so nothing surprises you in the final weeks.
Down payment help you might be missing
Beyond your own savings, first-time buyers in this region have real programs available — the FHSA, the RRSP Home Buyers' Plan, and forgivable municipal down payment loans specific to London-Middlesex, Waterloo Region, and St. Thomas-Elgin. My full breakdown of down payment assistance programs covers exact amounts and eligibility for each.
Where to actually look across the region
London, St. Thomas and the Kitchener-Waterloo-Cambridge triangle each offer very different entry points for a first-time buyer — from White Oaks and East London on the affordable end, to Miller's Pond's new construction in St. Thomas, to Eastbridge in Waterloo for families priced out of pricier pockets. Rather than repeat that breakdown here, my dedicated first-time buyer guides for London & St. Thomas and Kitchener-Waterloo go pocket by pocket for each region.
The mistakes that cost first-time buyers the most
Skipping pre-approval, waiving conditions without understanding the risk, and underestimating closing costs are three of the ten mistakes I see most often — my full list covers all ten with what each one actually costs you.
Working with the right agent
A buyer's agent should be working for your interests specifically, not the seller's — my guide on choosing the right agent covers the exact red flags to watch for before you commit to anyone.
Frequently asked questions
How much money do I actually need saved to buy my first home?
At minimum, your down payment (5% on the first $500,000) plus closing costs (1.5–4% of the purchase price). On a $500,000 home, that's roughly $32,500 to $45,000 all-in, before accounting for moving costs or immediate repairs.
Is my credit score good enough to buy a home?
A score above 660 generally opens up mainstream lending options, and above 700 typically qualifies you for the best rates — but a mortgage broker can confirm exactly what you qualify for with your specific score and income, since lenders weigh several factors together.
What's the biggest first-time buyer mistake?
Touring homes before getting a real mortgage pre-approval — it leads to falling for a home you can't finance, or underestimating your own budget and missing homes you could actually afford.
Do I need 20% down to buy my first home?
No — the minimum is 5% on the first $500,000 of the purchase price. Putting down less than 20% requires CMHC mortgage default insurance, which adds a premium to your mortgage but doesn't require a large upfront down payment.
Should I use the seller's agent to save money?
No — a seller's agent represents the seller's interests, not yours, even if they're technically willing to work with you. A buyer's agent working exclusively for you costs you nothing extra in most transactions, since the seller typically pays both sides of the commission.
