Key takeaways
- →Approval isn't the finish line — most lenders reserve the right to re-verify credit and employment closer to funding, and a spike in utilization or a new account can surface there.
- →A big pre-closing purchase changes two things at once: the credit picture at re-pull, and the debt-service ratios (GDS/TDS) the file was originally approved against.
- →This is one of the easiest problems to prevent and one of the hardest to fix once it happens — the fix is a conversation before the purchase, not a scramble after.
- →New inquiries and new balances both count — even a purchase with a promotional 0% rate still shows up as new debt on the bureau.
Every experienced broker has a version of this story: a file sails through approval, and then the client finances a new car, a large appliance, or a wedding on a store card before the deal funds — and the numbers underwriting approved no longer match the file at closing.
It's one of the most preventable problems in the whole process, and one of the most common, because clients genuinely don't connect “the mortgage is approved” with “the file can still change before it funds.”
01 · Why do clients keep making major purchases right before closing?
From a client's point of view, approval feels like the finish line — the hard part is over, so a new couch or a car to replace the one that just died feels unrelated to a deal that's already been approved. Nobody tells them otherwise unless the broker specifically does.
02 · What do lenders actually re-check between approval and funding?
Practice varies by lender, but many will re-verify credit, employment, or both closer to the funding date, particularly on longer closings, and virtually all reserve the contractual right to do so even when they don't always exercise it. A fresh credit pull that shows a new account, a new inquiry, or a meaningfully higher balance than what the file was approved against can trigger a re-review of the deal.
03 · What actually changes on the file when utilization spikes before closing?
Two things move at once. First, the credit score itself can drop, since utilization is one of the more heavily weighted factors in most scoring models. Second — often more consequential — the new payment obligation changes the GDS/TDS ratios the file was originally qualified against, which can push a borderline file outside the lender's or insurer's approved ratios entirely, independent of what happens to the score.
04 · How should a broker actually prevent this before it happens?
The single most effective step is telling every client, at the point of approval — not at the point of closing — not to open new credit, finance a major purchase, cosign for anyone, or make any large, unexplained withdrawal or deposit before the deal funds. Putting this in writing, a short, plain-language note at conditional approval, gives the client something concrete to refer back to when they're standing in a furniture showroom weighing a 0%-financing offer.
Approval isn't the finish line
Give every client the “don't finance anything” conversation — before it's too late.
Treadstone's fulfillment associates build the pre-closing client checklist into every file, so a last-minute purchase doesn't become a last-minute crisis.
05 · What should a broker do if a client makes a major purchase anyway?
Tell the lender proactively rather than hoping it doesn't surface at re-pull — a lender who hears about it from the broker, with the new payment already factored back into the ratios, is in a very different position than one who discovers it independently at funding. It may still work, particularly on a file with room in the ratios; it's the surprise, not necessarily the purchase itself, that causes the worst outcomes.
