The financing difference that catches buyers off guard
With a resale home, financing is straightforward: you get a pre-approval, make an offer, the lender appraises the specific property, and you close in weeks with a firm mortgage at a locked rate. What you sign for is what you get.
Pre-construction is fundamentally different because your closing might be years away, and no lender will firmly commit a mortgage rate that far into the future. You'll typically get a pre-approval at purchase, but the binding mortgage — the actual rate and final qualifying — is set close to completion. That means your rate could be higher (or lower) by then, and just as importantly, your qualifying could change: if your income, the rules, or rates have shifted by completion, the amount you can borrow may differ from what you assumed when you signed. One upside: if your purchase is insured, buyers of newly built homes can use a 30-year amortization (Department of Finance Canada). Still, qualifying risk is the single biggest pre-construction risk, and it's why a financing plan matters from day one — see our pre-construction mortgage guide.
