Loan-to-value (LTV)

The mortgage as a percentage of the property's value, which decides your insurance, your pricing tier and how much you can borrow.

Also called LTV.

LTV is the mortgage amount divided by the lower of the purchase price and the appraised value. A $400,000 mortgage on a $500,000 home is 80% LTV.

Almost every rule in Canadian mortgage lending is set as an LTV limit. Above 80%, the mortgage must be default-insured. A refinance is capped at 80%. A standalone HELOC is capped at 65%, or 80% combined with an amortizing portion. Insurance premium bands step at 80%, 85%, 90% and 95%.

Because the ratio uses the lower of price and appraised value, a low appraisal raises your LTV. That can push you into a more expensive band or out of a product entirely.

Moving across an LTV threshold is often worth more than shopping for a better rate. The difference between 80.5% and 79.9% can be a whole pricing tier.
