Looking for a mortgage broker in Vaughan?

The average Vaughan detached home has crossed the insured mortgage cap

This is the number that should shape your Vaughan plan. In TRREB's September 2026 Market Watch the average detached home in Vaughan sold for $1,599,218 — above the $1.5 million insured mortgage cap. Above that cap, mortgage default insurance is unavailable at any price. Not expensive. Unavailable. Which means 20% down is the legal minimum, and on an average-priced Vaughan detached home that is roughly $319,844.

It also means your mortgage is uninsured, and uninsured mortgages at federally regulated lenders must pass the stress test: you have to qualify at the greater of your contract rate plus 2% or 5.25%. That requirement was unchanged as of 29 January 2026. On a file this size the stress test, not the down payment, is very often the binding constraint — plenty of Vaughan buyers have the cash and fall short on the qualifying calculation.

The flip side is that there is no insurance premium to pay, and no Ontario PST on a premium to find at closing. You also have more latitude on amortization than an insured file permits. It is a different structure, not simply a harder one.

The rest of Vaughan's market sits on the other side of the line. Condo apartments averaged $548,958, condo townhouses $747,688, attached townhouses $992,857 and semi-detached homes $1,024,654 — all insurable, all on the tiered minimum of 5% of the first $500,000 plus 10% above it. The gap between a Vaughan semi and a Vaughan detached is not just price; it is two different sets of rules.

Vaughan's new-build supply unlocks something most buyers miss

Vaughan has absorbed more new construction than almost anywhere in the GTA — high-rise around the Vaughan Metropolitan Centre, and a steady pipeline of new freehold in Kleinburg, Patterson and the northern edges. If you are buying one of those, there is a rule worth knowing.

On an insured mortgage, a 30-year amortization is available if either at least one borrower is a first-time buyer or the property is newly built. It is either/or, and the second branch is the one Vaughan buyers overlook. A repeat buyer — someone who already owns, or has owned, a home — purchasing a brand-new Vaughan townhouse or condo qualifies for the 30-year amortization on the strength of the property being new. I see this missed on new-build files constantly, and it directly affects what you qualify for.

The conditions: it applies to high-ratio owner-occupied purchases only, so it does not extend to a rental property, and it requires the mortgage to be insured — which means the price must be under $1.5 million. On a new Vaughan detached home above the cap, the 30-year insured option is simply not on the table. CMHC also adds a 0.20% premium surcharge when a first-time buyer takes the 30 years; a repeat buyer qualifying via the new-build branch is not subject to that surcharge.

New-build financing has its own mechanics regardless. Your purchase price was set in an agreement signed earlier; the appraisal happens near completion; interim occupancy and final closing are separate events with separate costs; and development levies and adjustments arrive at the end. Get the pre-approval done properly and revisit it as completion approaches, because lender rate holds and your own circumstances both move.

Land transfer tax in Vaughan: no municipal tax, and a $4,000 provincial refund

Vaughan is in York Region, outside the City of Toronto, so you pay the Ontario provincial land transfer tax only. There is no municipal land transfer tax in Vaughan, or anywhere else in York Region — not in Markham, not in Richmond Hill. Toronto is the only municipality in Ontario that charges its own.

That boundary is Steeles Avenue, and it is worth understanding if you are also looking at North York. A buyer comparing a house on the north side of Steeles with one on the south side is comparing two different closing-cost regimes on streets that look identical. The Toronto side carries a second land transfer tax; the Vaughan side does not.

First-time buyers in Vaughan claim the Ontario provincial refund of up to $4,000, and the province charges no land transfer tax on the first $368,000 of the price. You cannot claim the Toronto municipal rebate of up to $4,475 here — but you are not paying the municipal tax either.

To qualify: at least 18 years old; occupy the home as your principal residence within nine months of the transfer; never have owned a home or any interest in one anywhere in the world; your spouse must never have owned a home anywhere in the world while married to you; and you must be a Canadian citizen or permanent resident, or become one within 18 months of the transfer. Apply within 18 months of registration.

Renewals, switches and equity in Vaughan

Vaughan homeowners who bought before the last run-up hold a lot of equity, and most lenders cap a refinance at 80% of the appraised value as standard practice — that is the ceiling on what you can access, whether through a refinance, a HELOC, or consolidating higher-interest debt into one secured payment. A refinance is always stress-tested at the greater of your contract rate plus 2% or 5.25%.

At renewal you have a useful exemption. OSFI does not expect lenders to apply the minimum qualifying rate to an uninsured straight switch — same loan amount, same remaining amortization, no new money. That took effect on 21 November 2024, and it means you can often move your mortgage to a better-fitting lender without re-qualifying under the stress test. Add to the balance or change the amortization and it is no longer a straight switch. The switching page explains what survives the test and what does not.

Breaking a term early usually costs the higher of three months' interest or the interest rate differential. Which of those applies, and how large the differential is, depends on your lender's calculation method and the wording of your contract — there is no dependable shortcut. Send me your commitment and I will read it before quoting you anything.
