Mortgage terms, in plain English.
Whether you're buying your first home, renewing, or refinancing — these are the words you'll hear from agents and lenders, explained without the jargon.
A
A Lender
LendersA federally regulated bank, credit union, or trust company that issues prime mortgages to borrowers who meet OSFI's stress-test rules.
Accelerated Payments
Mortgage basicsBi-weekly or weekly payments calculated as half (or a quarter) of the monthly amount — pays the mortgage off ~3 years early.
Adjustable-Rate Mortgage
Mortgage productsA variable-rate mortgage where your payment changes when prime moves — different from a fixed-payment VRM where the payment stays put.
Amortization
Mortgage basicsThe total length of time it takes to fully pay off your mortgage if you make every scheduled payment without changes.
Appraisal Fee
Costs & feesFee for a third-party valuation of the property. Typically $300–$500. Required by the lender on most uninsured deals.
B
C
Closing Costs
BuyingOne-time fees and taxes payable on closing day, typically 1.5–4% of the purchase price.
CMHC Insurance
InsuranceMandatory default insurance when your down payment is under 20%. Protects the lender. Provided by CMHC, Sagen, or Canada Guaranty.
Commission
Costs & feesThe fee a mortgage agent earns. Paid by the lender on most A Lender deals; sometimes by the borrower on B Lender or private deals.
Conventional Mortgage
Mortgage productsA mortgage where the borrower has at least 20% down, so no default insurance is required.
Credit Bureau
CreditAn organisation that compiles your credit history and produces your credit report. In Canada: Equifax and TransUnion.
Credit Score
CreditA 300–900 summary of your credit history. Lender minimums vary: B Lenders near 500, A and insured deals near 600, preferring 680+.
D
Debt Service Ratio
QualificationThe percentage of your gross income that goes to debt payments — the foundation of mortgage qualification math.
Discharge Fee
PenaltiesThe administrative fee a lender charges to remove their mortgage registration from title when you pay off the loan or switch lenders.
Down Payment
BuyingThe cash portion you pay upfront. Minimum 5% on the first $500,000 and 10% on the portion above. 20%+ avoids CMHC insurance.
F
First Home Savings Account
BuyingA federal savings vehicle for first-time homebuyers: contributions are tax-deductible like RRSP, withdrawals are tax-free like TFSA.
Fixed-Rate Mortgage
Mortgage productsA mortgage where the interest rate stays the same for the entire term, so your payment never changes mid-term.
G
GDS / TDS Ratio
QualificationTwo debt-service ratios lenders use to qualify you. GDS = housing costs ÷ income; TDS = housing + all other debts ÷ income.
Gifted Down Payment
BuyingA down payment funded partially or fully by a gift from immediate family — common in Canada, but the gift letter must follow strict rules.
GST HST New Housing Rebate
Costs & feesA federal (and sometimes provincial) rebate of part of the GST/HST paid on a newly built or substantially renovated home.
H
High-Ratio Mortgage
Mortgage productsA mortgage where the down payment is less than 20% of the purchase price. Default insurance is required.
Home Equity Line of Credit
Mortgage productsA revolving credit facility secured against your home equity. Interest-only payments, prime-plus rate, drawn and repaid as needed.
I
Interest Adjustment Period
Costs & feesThe few-day gap between funding day and your first regular mortgage payment — interest is prorated by days.
Interest Rate Differential (IRD)
PenaltiesA penalty calculation used when you break a fixed-rate mortgage early. Often much higher than three months' interest.
L
M
Mortgage Broker
RolesA licensed professional who shops your mortgage application across multiple lenders and presents you with options.
Mortgage Broker Fee
Costs & feesA fee the borrower pays the mortgage agent on B Lender, private, or specialty deals. Always disclosed in writing before signing.
Mortgage Funding
BuyingThe day the lender wires the mortgage to your lawyer, who completes the purchase and transfers ownership to your name.
Mortgage Renewal
Mortgage basicsRe-signing your mortgage at the end of the term, either with the same lender at their offered rate or by switching to a different lender.
Mortgage Term
Mortgage basicsYour contract length with one lender at one rate — typically 1 to 5 years. Different from amortization (total payoff window).
Mortgage Trigger Rate
Mortgage productsOn a fixed-payment variable mortgage, the rate at which the regular payment no longer covers monthly interest. Lender then requires action.
O
P
Portable Mortgage
Mortgage basicsA feature that lets you move your existing mortgage rate and term to a new property when you sell and buy at the same time.
Pre-approval
BuyingA lender's conditional commitment to lend you up to a specific amount at a specific rate, typically valid for 90–120 days.
Prepayment Penalty
PenaltiesThe fee charged when you pay off, refinance, or break your mortgage before the term ends.
Prepayment Privilege
Mortgage basicsYour right to pay extra principal each year without penalty — typically 10–20% of the original balance plus a payment-amount increase.
