HELOC stands for Home Equity Line of Credit, also commonly referred to as a secure line of credit.
This credit facility operates in the same way as any existing unsecured line of credit you may have. The difference is by providing collateral of your home equity, the rate premium applied above prime drops from 2-5% down to 0.5%, giving you a lower cost of borrowing.
At present, the Bank of Canada prime is 3.95% resulting in a 4.45% net cost of borrowing, charged at interest only.
HELOC's can be obtained up to 80% of the value of your house, less any existing mortgages owing. For example, if your home is worth $500,000, the allowable equity at 80% max is $400,000. If you presently owe $300,000 on your mortgage, the available equity in your home that you can provide in seeking a secure line of credit is $100,000.
