What documentation is required for mortgage approval in new construction?

Thorough loan documentation is essential, providing a clear record of credit decision factors and supporting lender risk management [osfi-b20-baseline, Loan documentation].

This enables independent audits by FRFIs (federally-regulated financial institutions) and OSFI (Office of the Superintendent of Financial Institutions).

Key Points

  • Your lender needs to keep detailed records to show they followed the rules when approving your mortgage.

  • You'll need to provide documents like proof of income, details about your debts, your down payment, the purchase agreement, and home insurance information.

  • If you have any credit issues, be prepared to explain how you're managing them and why you can still afford the mortgage.

  • If your mortgage is insured, the lender will keep a record confirming the insurance company's commitment.

  • Your lender may ask for updated information about your finances or the property, especially if something changes during the construction process.
