Home equity is the portion of a property's market value that belongs to the owner outright — the difference between the property's current value and the total balance owed against it.
Equity builds two ways: the property's market value rising over time, and the borrower paying down the mortgage principal with each payment. It's the foundation behind a loan-to-value calculation, since LTV is really just measuring how much of the property's value is still owed against versus how much equity the owner holds.
Not all of a homeowner's equity is available to borrow against. Under OSFI's guidelines, a standard refinance is generally capped at 80% loan-to-value, while the HELOC portion of a readvanceable mortgage is capped lower, at 65% LTV. Products like an equity take-out refinance or a reverse mortgage exist specifically to let homeowners access built-up equity without selling.
Refinance capped at 80% LTV: OSFI's guidelines generally limit a standard mortgage refinance to 80% loan-to-value, meaning at least 20% of a property's value must remain as equity.
HELOC portion capped lower, at 65% LTV: the revolving HELOC component of a readvanceable mortgage is limited to 65% loan-to-value, even though the combined mortgage-plus-HELOC can go up to 80%.
Equity underpins LTV: equity and loan-to-value are two ways of describing the same relationship between a property's value and what's owed against it.
Multiple ways to access it: an equity take-out refinance, a HELOC, or a reverse mortgage all let a homeowner convert built-up equity into cash without selling the property.
A homeowner checks their current position:
$700,000 − $420,000 = $280,000. Not all of this is necessarily borrowable, since refinance and HELOC limits cap how much can be accessed.
