What this means if you're buying in Newmarket
Market conditions shape the negotiation; your income, debts and the stress test decide what you can actually borrow. Most purchases here fall comfortably under the insured cap, which makes the sliding-scale down payment genuinely useful: 5% of the first $500,000 plus 10% of the balance means a million-dollar purchase needs $75,000 rather than $200,000. If you are buying with less than 20% down, remember the insurance premium is added to the mortgage rather than paid up front, and factor that into the payment you are budgeting for rather than being surprised by it at signing.
