At what down payment threshold does a homebuyer no longer require mortgage default insurance in Canada?
Correct Answer
B) 20% of purchase price
Mortgage default insurance is mandatory for all mortgages with less than 20% down payment. Once a buyer puts down 20% or more, they have a conventional mortgage that does not require default insurance.
Why This Is the Correct Answer
Option B is correct because federal mortgage insurance regulations mandate that all mortgages with loan-to-value ratios exceeding 80% (down payments less than 20%) must carry mortgage default insurance. Once a borrower provides a 20% down payment, they achieve an 80% loan-to-value ratio, qualifying for a conventional mortgage that does not require default insurance. This threshold is consistently applied across all federally regulated lenders and mortgage insurers in Canada.
Why the Other Options Are Wrong
Option A: 15% of purchase price
15% is insufficient to avoid mortgage default insurance requirements. At 15% down, the loan-to-value ratio is 85%, which exceeds the 80% threshold where insurance becomes mandatory. Borrowers would still need to pay insurance premiums.
Option C: 25% of purchase price
25% exceeds the minimum requirement to avoid mortgage default insurance. While a 25% down payment certainly eliminates the need for insurance, it's not the threshold where insurance is no longer required - that occurs at the lower 20% level.
Option D: 30% of purchase price
30% is well above the threshold for avoiding mortgage default insurance. This represents unnecessary capital deployment, as insurance requirements are eliminated at the much lower 20% down payment level.
Deep Analysis of This Mortgage & Real Estate Finance Question
Mortgage default insurance is a critical component of Canada's housing finance system, designed to protect lenders against borrower default while enabling homeownership with smaller down payments. The 20% threshold represents the dividing line between high-ratio mortgages (requiring insurance) and conventional mortgages (no insurance required). This threshold is established by federal regulations and enforced by mortgage insurers like CMHC, Genworth, and Canada Guaranty. The 20% rule reflects actuarial data showing that borrowers with larger equity stakes have significantly lower default rates. This concept directly impacts affordability, as insurance premiums can add thousands to the total mortgage cost. Understanding this threshold is essential for real estate professionals advising clients on financing options and calculating total acquisition costs.
Background Knowledge for Mortgage & Real Estate Finance
Mortgage default insurance protects lenders when borrowers default, enabling them to offer mortgages with down payments as low as 5%. In Canada, three providers offer this insurance: CMHC (government), Genworth, and Canada Guaranty (private). Insurance is mandatory for all high-ratio mortgages (loan-to-value above 80%). The premium ranges from 0.6% to 4.5% of the mortgage amount, depending on down payment size and amortization period. This system balances homeownership accessibility with lender risk management, supporting Canada's housing market stability.
Memory Technique
The 80/20 RuleRemember '80/20 Vision' - when you have 20% down, you get 80% financing with clear vision (no insurance fog). Just like the Pareto Principle, 20% down payment eliminates 80% of the insurance headache.
When you see mortgage insurance questions, immediately think '80/20 Vision.' If the down payment is 20% or more, you have clear vision - no insurance required. Less than 20% means foggy vision - insurance needed.
Exam Tip for Mortgage & Real Estate Finance
Look for the 20% threshold in mortgage insurance questions. Any down payment of 20% or higher means conventional mortgage with no insurance required. Below 20% always requires insurance.
Real World Application in Mortgage & Real Estate Finance
Sarah is purchasing a $500,000 home and has saved $100,000 for a down payment (20%). Her mortgage broker explains that because she meets the 20% threshold, she qualifies for a conventional mortgage without default insurance, saving her approximately $19,000 in insurance premiums. If she had only $95,000 (19% down), she would need insurance, adding significant cost to her mortgage.
Common Mistakes to Avoid on Mortgage & Real Estate Finance Questions
- •Confusing the 20% down payment threshold with other mortgage qualification ratios
