7 Mistakes to Avoid When Buying Pre-Construction Condos in the GTA (2025 Guide)

Buying a pre-construction condo in the Greater Toronto Area (GTA) can be an exciting way to enter the market or invest in real estate. With sleek modern finishes, attractive pricing plans, and the promise of brand-new living spaces, it's no wonder many buyers are drawn in.

But behind the glossy brochures and model suites lie important details that every buyer must understand. Here's your ultimate guide to avoiding the most common and costly mistakes when buying pre-construction condos in 2025.

1. Not Understanding the Total Cost

Many buyers focus only on the base price. But in reality, you’ll be paying more than that.

Additional costs include:

• Development charges

• Utility connection fees

• Legal fees

• Occupancy fees (aka “phantom rent”)

• HST (if it's an investment)

📌 Tip: Always ask for a full cost breakdown from the builder and work with a lawyer who specializes in pre-construction.

2. Ignoring the 10-Day Cooling-Off Period

In Ontario, you get a 10-day cooling-off period after signing the Agreement of Purchase and Sale.

This is your legal window to:

• Have a lawyer review the contract

• Ensure financing is pre-approved

• Walk away without penalty if you change your mind

📌 Tip: Use this time wisely. Many regret not reading the fine print until it's too late.

3. Skipping the Fine Print in the Builder's Agreement

Pre-construction contracts are heavily tilted in the builder’s favour. Delays, layout changes, or even cancellations can be allowed.

Common red flags to watch for:

• Closing dates with wide flexibility

• Builder’s right to change square footage or design

• High assignment fees (if you want to sell before closing)

📌 Tip: Have your real estate lawyer review every clause before your 10-day period ends.

4. Overlooking the Developer’s Reputation

Not all builders are equal. Some have a track record of delayed deliveries, poor quality, or even lawsuits.

📌 Tip: Always research:

• Online reviews and forums

• Past project timelines

• Tarion Warranty coverage

• Their standing with the Home Construction Regulatory Authority (HCRA)

5. Not Getting Pre-Approved or Misunderstanding Financing

Just because you can afford the deposit structure doesn’t mean the bank will finance the full mortgage later.

📌 Tip: Speak with a mortgage broker who understands pre-construction lending. Lock in pre-approvals and understand what happens if rates increase by the time of closing.

6. Forgetting to Budget for Interim Occupancy

In condos, you might get the keys before you officially own the unit. This is called interim occupancy, and during this period, you’ll pay monthly fees to the builder.

These fees do not go toward your mortgage.

📌 Tip: Budget for 3–9 months of occupancy costs, depending on the building and phase.

7. Choosing the Wrong Unit or Floor Plan

Buyers often get emotionally swayed by the showroom experience and rush into picking a unit.

📌 Tip: Focus on:

• Resale value (views, layout, location in the building)

• Square footage efficiency

• Natural light and flow

A good realtor will guide you toward units that are easier to sell or rent later — even if they're not the flashiest.
