A quoted rate from one bank in May does not tell you what a credit union or a mortgage broker was offering the same week, since the spread between lenders on a given day can run wider than most buyers expect.
The number that matters for your file is the rate hold on your own pre-approval letter, typically good for 90 to 120 days, not a headline figure from a rate comparison site.
A mortgage broker working live files can tell you what is actually being offered this week far better than any archived figure. Get your hand-reviewed valuation from Joel Dyck.
