How Construction Mortgages Work

A construction mortgage is a specialized financing product designed for building new homes. Unlike a standard mortgage where you receive all the funds at once, construction mortgages release money in stages called "draws" as your home is built.

This type of mortgage is more complex than a traditional purchase mortgage because the lender needs to monitor construction progress and protect their investment throughout the building process.

Two Types of Construction Financing

Construction-to-Permanent:

One mortgage that converts to a permanent mortgage once construction is complete

Stand-Alone Construction:

Separate construction loan that must be refinanced into a traditional mortgage later

The Construction Draw Process

Your mortgage funds are released in stages as construction milestones are reached:

Typical Draw Schedule

1
Initial Draw (15-20%)
Upon signing and starting foundation
2
Foundation Complete (25%)
When foundation and basement are finished
3
Framing Complete (25%)
When structure and roof are done
4
Lock-Up (20%)
Windows, doors installed, exterior complete
5
Final Draw (10-15%)
Upon completion and occupancy

Down Payment Requirements

Construction mortgages typically require larger down payments because lenders see more risk in the building process:

  • 20% minimum for homes under $1 million
  • 20%+ for million-dollar+ properties (may need more)
  • Self-build may require 25-30% down payment

Key Differences from Regular Mortgages

Interest During Construction

You typically pay interest only on funds drawn, not the full amount. This keeps costs lower during the building phase.

Progress Inspections

Lenders send appraisers to verify construction progress before each draw release.

Longer Timeline

Construction mortgages have longer approval and draw processes than traditional mortgages.

Builder Approval

Lenders may vet your builder's credentials, financial stability, and past projects.

GST/HST New Housing Rebate

Don't forget about the GST/HST new housing rebate! If you're building a new home, you may be eligible to recover some of the GST/HST paid:

  • Rebate amount: Up to $24,000 for homes priced under $450,000
  • Your builder often handles the application on your behalf
  • Budget for GST - It adds 5% (GST) or up to 15% (GST+HST) to your total construction cost
