Private mortgage lending in Markham

The July 2026 average detached sale here was $1,507,841 — within a rounding error of the $1.5-million ceiling above which CMHC, Sagen and Canada Guaranty insurance is simply unavailable. The all-types average was $1,131,324, well below it. That means a Markham detached search is a search across a cliff edge: at $1,480,000 the tiered minimum down payment applies — 5% on the first $500,000 plus 10% on the balance, about $123,000 — while at $1,520,000 default insurance cannot be purchased at all and the minimum is a full 20%, roughly $304,000. A $40,000 difference in price can be a $180,000 difference in cash required at closing. Crossing the line also removes the 30-year amortization available on insured mortgages to first-time buyers and new-build purchasers, so the payment the stress test is applied against rises on the same loan. None of this is a reason to avoid Markham detached; it is a reason to decide in advance which side of the ceiling your budget is on, and to treat the ceiling — not your pre-approval amount — as the number that governs the negotiation. Unionville and Cathedraltown will more often sit above it; the Highway 7 condo corridor and the townhome stock sit clearly below.

First, interim occupancy: you can take possession months before the building registers, paying an occupancy fee to the builder during that window that builds no equity and is not a mortgage payment. Second, the final-closing appraisal: your price was agreed years ago, but the lender values the unit as at closing day. If the appraisal comes in lower, the lender lends against the lower figure and the shortfall is cash you provide on top of your deposits. Third, assignments — selling your contract before closing — which carry HST, assignment-clause and lender considerations that a resale never does, and which not every lender will finance for the incoming buyer. The habit worth forming is to treat the purchase agreement, not the final closing, as the moment for the financing conversation. Deposit structure, the likely occupancy period, whether the builder's timeline can outlast a rate hold, and what happens if the appraisal disappoints are all knowable at signing and expensive to discover at closing. Our pre-construction mortgage page covers the sequence in detail.

A buyer is pre-approved with about $130,000 available for a down payment and closing costs, shopping detached homes in the low $1.4-millions where the tiered insured minimum comfortably fits. Competition pushes the accepted price just past $1.5 million. Because default insurance is unavailable above that line, the minimum down payment jumps from roughly 8.7% to a full 20% — a swing of well over $150,000 that has to appear in cash before closing, from savings, a gift, or an existing property. The pre-approval did not fail; the product did, because a different set of rules now applies to the same borrower. What prevents it is knowing the ceiling before the bidding starts and treating it as a hard budget constraint rather than a technicality. Given that Markham's detached average sat at $1,507,841 in July 2026, this is the ordinary case in this market rather than an unlucky one. Every real file is assessed on its own facts.
