How do B-20 guidelines impact the loan-to-value (LTV) ratio for uninsured mortgages issued by federally regulated institutions?

Question: How do B-20 guidelines impact the loan-to-value (LTV) ratio for uninsured mortgages issued by federally regulated institutions?

Answer options: ✅ They require lenders to use more conservative LTVs primarily through enhanced affordability assessments, rather than direct LTV caps.

• They mandate a maximum LTV of 65% for all uninsured mortgages.
• They have no impact on LTV ratios; only on debt service ratios.
• They stipulate that LTV calculations must include future property value forecasts.

Correct answer: They require lenders to use more conservative LTVs primarily through enhanced affordability assessments, rather than direct LTV caps.

Explanation: While B-20 guidelines don't set a direct maximum LTV for uninsured mortgages like they do for insured ones, the stress test requirements inherently lead to more conservative lending. By making it harder for borrowers to qualify for larger loans based on affordability, it indirectly impacts the practical maximum LTV borrowers can achieve, pushing lenders towards more prudent risk management through robust income and debt servicing assessments.
