A secured line of credit is set up against a property you own and works like a large checking account with funds available to access at any time. Interest only accrues on the funds you actually use, and you can make a minimum interest payment or a larger payment to pay it down faster.
An advanceable line of credit is a dynamic facility that allows you to roll the balance into a mortgage at any time. As you pay down principal on your mortgage, the limit on the line of credit automatically increases by the same amount without requiring you to requalify, building capital for future investments or emergencies.
An interest-only payment on a line of credit is often lower than a principal and interest mortgage payment. For example, using $50,000 from a secured line of credit at 2.95% results in an interest-only payment of approximately $123 per month, whereas a $50,000 mortgage at 2% would cost about $185 per month.
Rates on lines of credit are typically higher than mortgage rates, and if a property has no mortgage, the maximum you can access through a bank is 65% of the value rather than 80%. You must also still qualify for a secured line of credit using the same rules and process as a mortgage qualification.
