The first-time-buyer refund is capped at $4,000, which here covers only 17% of the tax; a first-time buyer still owes $18,964.
All told, the minimum cash to close at this price — before legal fees, title insurance and adjustments — is about $130,412. Check other prices in the land transfer tax calculator.

The $1,324,472 figure is Oakville’s average price for August 2026 (the latest we have sourced), from Oakville average selling price, TRREB Market Watch.
Our Oakville guide works through the 3 questions that decide most files here:
- In Oakville, the mortgage-insurance ceiling is the normal case, not the edge case. Most Ontario markets brush the $1.5-million mortgage-insurance ceiling occasionally.
- Halton closing costs and the independent legal review on larger Oakville files. Oakville is in Halton Region, so a purchase here pays Ontario land transfer tax only — no municipal land transfer tax of the kind the City of Toronto charges on top, which would roughly double the bill and is payable in cash on closing.
- An illustrative Oakville file: the offer that crossed the line. This is an illustrative composite built from the rules above — not a specific client, and not a promised outcome.
How Oakville neighbourhoods change the file
In 3 of these 7 Oakville pockets the deciding rule is the $1,500,000 insurance ceiling — above it, 20% down is the legal minimum rather than a choice.
Old Oakville
Heritage detached near the harbourHeritage designation restricts alterations and narrows the appraiser's comparable set, and values sit well above the $1.5M insured ceiling — so 20% down is the legal minimum and the appraisal carries the file.
Glen Abbey
1980s–90s executive detachedConsistent vintage and a large sample of similar homes make appraisals predictable, which matters because most of this stock is uninsurable and the lender is relying on value rather than default insurance.
West Oak Trails
2000s detached and townhouse subdivisionNewer stock sitting closer to the $1.5M insurability line than the rest of the town, so whether default insurance is even available on an owner-occupied purchase is a per-property question here. Freehold towns with a common-elements fee still carry that fee into your ratios.
Joshua Creek
Executive detached (large newer homes)Reliably above the insured ceiling: conventional financing only, 20% down as a legal floor, and tighter debt-service review on the larger loan amounts these prices imply.
Bronte
Mixed — waterfront condo and older detachedThe harbour condo stock is a corporation review, where reserve fund and rental share move the lender list. The older detached behind it is an appraisal file, often straddling the $1.5M line.
River Oaks
1990s detached and townhouseMid-band family stock with deep owner tenure, which makes refinance and HELOC work a large share of local volume. Every take-out stops at 80% loan-to-value.
Clearview
Established detached, mature lotsLow-turnover pocket where long ownership has built substantial equity. Prices near the insured ceiling mean the practical question on a purchase is whether the file is conventional-only from the start.
