• Appraisal of the property

• Confirmation of down payment source
• Home insurance

Conditional Mortgage Approval: What You Need to Know

The Impact of the OSFI Stress Test

Appraisal and Inspection

Down Payment and Source of Funds

Your lender will want to confirm that your down payment comes from legitimate sources. Be prepared to provide documentation such as bank statements, investment account summaries, or a gift letter if the funds are coming from a family member.

Home Insurance

Lenders require proof of home insurance before closing. Shop around for the best rates and ensure you have adequate coverage for your needs. Remember that mortgage default insurance (CMHC, Genworth, Canada Guaranty) is required for down payments less than 20%.

Legal Review
