Does a mortgage pre-approval affect your credit score? The short answer
Yes — but far less than most people fear. A full, verified mortgage pre-approval involves a hard credit inquiry, and a single hard inquiry can lower your score by a small amount for a short time. That’s the honest answer. The important context is that this dip is minor and temporary, that an early estimate can often be done with no impact at all, and that how you shop for a mortgage matters more to your credit than the pre-approval itself.
So the fear that getting pre-approved will ‘wreck’ the score you need to qualify is mostly a myth. For a typical buyer, one mortgage inquiry is a small, recoverable factor — dwarfed by things like missed payments or high card balances. The rest of this page explains the mechanics: hard versus soft pulls, the single-inquiry advantage of using a broker, and Canada’s rate-shopping window.
