Ajax is a first-purchase market, and the tiered minimum is the number that matters
Ajax's July 2026 average selling price was $907,336, comfortably below the $1.5-million ceiling above which mortgage default insurance is unavailable — which means the full insured toolkit is open here. The minimum down payment is tiered, not a flat 5%: 5% on the first $500,000 plus 10% on the balance, which at the local average works out to roughly $65,734. The default-insurance premium is then financed onto the mortgage rather than paid in cash, so the smaller cash outlay buys a slightly higher monthly payment. Two further levers are specific to a first purchase and worth using in combination. A 30-year amortization is available to first-time buyers and on new-build purchases on insured mortgages, which lowers the monthly payment that the stress test is applied against and can meaningfully raise the qualifying amount. And the down payment itself can be assembled tax-efficiently: the FHSA offers up to $40,000 of lifetime contribution room with tax-deductible contributions, and the RRSP Home Buyers' Plan permits a withdrawal repaid over 15 years — the two can be used together. What none of these change is the stress test itself, which qualifies you at the greater of your contract rate plus two percentage points or 5.25%. Our affordability calculator runs your own numbers against it.
