What are the key lending metrics I should be aware of?
The metrics lenders care about at renewal are GDS (<39%), TDS (<44%), Beacon score (680+ for prime), and LTV — not your lump-sum payment history.
Key Points
Lenders assess your (/glossary/loan-to-value) (LTV) ratio, which compares your mortgage amount to your home's appraised value.
Be prepared to show your lender where your down payment came from.
Lenders use Gross Debt Service (GDS) and Total Debt Service (TDS) ratios to determine how much of your income goes toward housing costs and total debt.
Amortization period affects your monthly payment and total interest paid over the life of the mortgage.
