Don't get blindsided at closing. We reveal the extra fees you need to budget for, from levies to Tarion warranty fees.

The sticker price is $600,000. So you budget $600,000, right? Wrong.

One of the biggest mistakes first-time pre-con buyers make is forgetting about "Closing Costs." Unlike resale homes, pre-construction units come with a unique set of fees. Let's break them down so you aren't surprised.

1. Development Levies

These are fees the city charges developers to build infrastructure (roads, parks, schools). Developers often pass these on to you.
Pro Tip: Always ask for these to be Capped in your agreement. A good agent can negotiate a cap (e.g., $10,000 max instead of an open-ended bill).

2. Tarion Warranty Enrollment

Every new home in Ontario needs a warranty. The enrollment fee is based on the purchase price and can range from $1,000 to over $2,000. It's mandatory, so budget for it.

3. HST (The Tricky Part)

If you're buying to live in the unit, the HST is usually included in the price. If you're an investor renting it out, you have to pay the HST rebate upfront (approx $24,000) at closing. Don't panic—you get this back from the government after you lease the unit, but you need the cash flow to close.

Standard for any property, but don't forget the Land Transfer Tax (double if you are in Toronto proper!).

Knowledge is power. When we review contracts for our clients, our #1 goal is minimizing these surprises.
