## Answer
Home Equity Lines of Credit (HELOCs) can be integrated into shared equity mortgages, offering borrowers flexible fund access. However, these products demand careful management due to the potential for amplified consumer debt. Consider the risk/reward tradeoff:

## Institutional highlights
- You need to be able to repay your home equity line of credit (HELOC) in full.
- OSFI guidelines do not specify a 65% maximum LTV for HELOCs; typical maximum combined LTV (including HELOC) is 80% for insured mortgages and up to 85% or more for uninsured, but no fixed 65% HELOC cap is mandated.
- The bank might lower your HELOC limit if your home's value goes down.
- No specific regulatory requirement mandates banks to keep average HELOC LTV below a fixed threshold; rather, OSFI B-20 guidelines regulate total mortgage and HELOC combined LTV and borrower qualification.
