Most first-time buyers budget for the down payment. Almost none of them budget properly for what comes after — the pile of closing costs that shows up in the weeks before you get your keys, and the neighbourhood-specific surprises that don't show up on any lender's worksheet.

Here's where we see people get caught, street by street.

Mistake #1: Thinking the Down Payment Is the Finish Line

The down payment is the biggest number, but it's not the only one. Between land transfer tax, legal fees, title insurance, appraisal costs, home inspection fees, and adjustments at closing (property tax, utilities, sometimes prepaid items the seller is owed back), most buyers need another 1.5% to 4% of the purchase price in cash on top of their down payment. On a $900,000 home, that's $13,500 to $36,000 that has nothing to do with your mortgage.

If you're putting down less than 20%, add mortgage default insurance to the list. CMHC premiums currently run from about 2.8% of the mortgage amount (15–19.99% down) up to 4.0% (5–9.99% down) — and that premium usually gets rolled into your mortgage, which means you're financing it, not paying it in cash, but it still raises your monthly payment.

Mistake #2: Getting Toronto Rules Confused With Vaughan Rules

We hear this one constantly. Buyers who've done their homework — sometimes too much of it on generic, Toronto-focused websites — show up expecting a municipal land transfer tax on top of the provincial one. Vaughan doesn't charge a municipal land transfer tax. Toronto does. If you're buying in Woodbridge, Maple, Vellore Village, or Kleinburg, you're only on the hook for the Ontario provincial land transfer tax, and as a first-time buyer you may qualify for a rebate of up to $4,000 against it. Knowing which set of rules actually applies to your purchase is worth real money — don't let a generic calculator built for a Toronto condo tell you what your Vaughan closing costs look like.

Mistake #3: Skipping the Inspection on an “Obviously Fine” Woodbridge Home

Woodbridge has some of the most established streets in the area, and that's exactly the problem — buyers see a well-kept exterior and assume the mechanicals behind the walls have kept pace. They haven't always. Original wiring, aging roofs nearing the end of their life, and older sump pump setups are common in homes that otherwise show beautifully. A home inspection on an established Woodbridge property isn't a formality — it's how you find out whether “move-in ready” is a description or a listing photo.

Mistake #4: Not Budgeting for the Extras That Come With Newer Construction in Maple

Maple's newer pockets — closer to Rutherford Road and up around the Block 27 development lands — come with their own version of this mistake, just pointed the other way. Buyers assume newer means fewer surprises, then get hit at closing with development levy adjustments, Tarion new home warranty enrollment costs, or HST considerations that resale buyers never have to think about. New construction has real advantages, but “newer” doesn't mean “cheaper to close.” It means a different list of costs, not a shorter one.

Mistake #5: Forgetting Your Property Tax Bill Isn't Final Yet

This one catches Vellore Village buyers more than most, because so much of the community was built out recently. When you buy new or relatively new construction, your first property tax bill is often based on a preliminary assessment — sometimes just the land, before the home's full value gets reassessed. That number can jump noticeably in year two once MPAC catches up. Budgeting off your first tax bill instead of asking what the reassessed number is likely to look like is a mistake we see cost people real monthly cash flow, a year after they've already moved in.

We cover this reassessment timing in more detail in our Vellore Village pricing breakdown.

Mistake #6: Waiving Conditions on a Kleinburg Property Without Testing the Well and Septic

Kleinburg's estate and rural properties come with a system most first-time buyers have never dealt with: private well water and septic, instead of municipal services. Skipping a well flow test or septic inspection to make an offer more competitive is one of the more expensive mistakes we see, because well and septic repairs or replacements aren't a small line item — they can run into the tens of thousands of dollars, and they're not something a standard home inspection always covers in depth. If a property is on well and septic, that inspection isn't optional, no matter how good the rest of the offer looks.

The Common Thread

Every one of these mistakes comes from the same place: applying generic advice to a specific property, in a specific neighbourhood, with its own quirks. What closes cleanly in Woodbridge doesn't necessarily apply in Kleinburg, and what a Toronto buyer needs to know isn't what a Vaughan buyer needs to know.

If you're a first-time buyer and want the real list of what closing will actually cost you — for your specific property, not a generic average — reach out. We'll walk you through it before you write the offer, not after.
