Buying a pre-construction home isn’t like purchasing an existing property where you can move in within 30-60 days. The pre-construction timeline spans months or even years, with multiple phases, deposit milestones, and potential delays that can catch unprepared buyers off guard.
Understanding this timeline is crucial for setting realistic expectations, planning your finances, and making informed decisions throughout the process.
The Complete Pre-Construction Timeline: 5 Essential Phases
Phase 1: Launch and Pre-Sales Period (Months 1-3)

The journey begins before most buyers even know a development exists. Builders often start with VIP launches and pre-sales events designed to generate early interest and secure committed buyers.
What Happens During Launch:
- Builder releases marketing materials, floor plans, and pricing
- VIP access offered to previous customers, real estate agents, and select investors
- Early bird incentives and promotional pricing available
- Model homes or sales centers open to the public
Why VIP Launches Matter: Getting VIP access can save you thousands of dollars and give you first choice of premium units, floors, and orientations. Many of the best units sell during this phase, often before public launch.
Timeline Reality Check: Popular developments can sell 50-70% of units during pre-sales, leaving limited options for general public launches.
Phase 2: Reservation and Deposit Collection (Months 1-6)
Once you’ve selected your unit, the reservation process begins. This phase involves securing your chosen property through a series of deposits and paperwork.
Typical Deposit Structure:
- Initial reservation: $5,000-$25,000 (refundable for 10 days in Ontario)
- 30-day deposit: 5% of purchase price
- Additional deposits: 5-15% spread over 6-18 months
- Final deposit: Before occupancy
Key Documents You’ll Receive:
- Purchase agreement and disclosure statement
- Builder’s warranty information
- Development timeline estimates
- Customization options and upgrade pricing
Pro Tip: Always review deposit schedules carefully. Missing a deposit deadline can result in losing your unit and forfeiting previous payments.
Phase 3: Purchase Agreement and Planning (Months 2-12)
After your initial reservation, you’ll have time to finalize your purchase agreement, review all documentation, and make customization decisions.
Critical Steps in This Phase:
- Legal review period: 10 days in Ontario to review all documents with a lawyer
- Customization selections: Flooring, cabinetry, fixtures, and upgrade options
- Mortgage pre-approval: Secure financing based on completion timeline
- Final agreement signing: Legally binding commitment to purchase
Important Considerations:
- Upgrade costs can add 10-30% to your base purchase price
- Mortgage rates may change between signing and occupancy
- Development plans can be modified during this phase
Phase 4: Construction Period (12-36 Months)
The longest phase of the timeline, construction can take anywhere from 12 months for townhomes to 36+ months for high-rise condominiums.
What to Expect During Construction:
- Regular progress updates from the builder
- Opportunities for site visits and inspections
- Potential timeline adjustments and delay notifications
- Pre-occupancy inspections and walk-throughs
Construction Milestones:
- Foundation and framing: 3-8 months
- Interior and mechanical systems: 6-12 months
- Finishing and landscaping: 2-6 months
- Final inspections and approvals: 1-3 months
Managing Expectations: Weather delays, permit issues, labor shortages, and supply chain disruptions can extend timelines by 6-12 months or more.
Phase 5: Occupancy and Final Closing (Months 24-48)
The final phase involves two distinct events that many buyers confuse: interim occupancy and final closing.
Understanding Occupancy vs. Final Closing
Interim Occupancy (For Condominiums)
What It Is: You can move into your unit, but you don’t legally own it yet. This typically occurs when your individual unit is complete, but the entire building isn’t finished.
What You’ll Pay:
- Occupancy fees: Monthly payments covering mortgage interest, maintenance fees, and property taxes
- Utilities and services: Hydro, internet, parking, and other monthly expenses
- No mortgage payments: Your official mortgage doesn’t start until final closing
Duration: Interim occupancy can last 6-18 months, depending on building completion and municipal approvals.
Final Closing
What It Is: Legal ownership transfers to you, and you receive the deed to your property.
What Happens:
- Your mortgage officially begins
- Legal title transfers to your name
- You receive keys and full ownership rights
- Warranty periods begin
Final Costs: Legal fees, land transfer taxes, utility connections, and final adjustments for property taxes and deposits.
Common Delays and How to Plan for Them
Typical Delay Causes
Weather-Related Delays: Harsh winters, excessive rain, or extreme temperatures can halt construction for weeks or months.
Permit and Approval Delays: Municipal approvals, zoning changes, and inspection schedules can add months to timelines.
Labor and Material Shortages: Skilled worker shortages and supply chain disruptions have become increasingly common.
Financial or Legal Issues: Builder financial problems or legal disputes can cause significant delays or project cancellations.
Planning for Delays: Essential Strategies
Financial Preparation:
- Maintain flexible rental arrangements with month-to-month leases
- Budget for extended interim occupancy periods
- Keep emergency funds for unexpected costs
Timeline Buffers:
- Add 6-12 months to builder estimates for planning purposes
- Avoid scheduling major life events around projected completion dates
- Consider temporary housing options if current lease expires early
Legal Protection:
- Review delay clauses in your purchase agreement
- Understand your rights regarding extended delays
- Know when you can legally withdraw from the purchase
Red Flags: When to Be Concerned
Project-Related Warning Signs:
- Construction stops for extended periods without explanation
- Builder misses multiple timeline updates
- Sales center closes unexpectedly
- Significant design changes without buyer consultation
Financial Red Flags:
- Builder requests additional deposits beyond the original schedule
- Difficulty reaching builder representatives
- Reports of other buyers having payment or communication issues
Making the Timeline Work for You
For First-Time Buyers
Use the extended timeline to improve your financial position, build credit, and save for additional costs like furniture and moving expenses.
For Investors
The long timeline allows you to research rental markets, plan property management, and potentially sell the assignment if market conditions change.
For Families
Plan major life events, school changes, and family growth around realistic completion timelines with generous buffers.
