A mortgage approval can still fall apart after an accepted offer if your debts, job, documents, or the property itself change or fail verification before funding. The approval is conditional until the lender has confirmed income, down payment, and the home’s value and condition — and re-checked that nothing material has changed. The safest approach between offer and closing is simple: change nothing financial without asking first. See how long a pre-approval lasts — and what voids it.
Can new debt really undo an approval?
Yes. A new car loan, furniture financed for the new home, or a large credit card balance raises your debt ratios, and lenders can re-check credit before funding. If the new payment pushes your ratios past the approval limits, the lender can reduce the mortgage or decline the file.
This includes co-signing for someone else and taking a “pay later” plan at checkout. If a purchase cannot wait until after closing, ask before you buy — sometimes the answer is fine, and sometimes waiting two weeks saves the house. If your credit needs work before underwriting, see rebuilding credit so the approval survives underwriting.
What happens if you change jobs after approval?
Employment is verified, sometimes again close to funding. Leaving a job, moving from salary to self-employment or contract work, or starting a new role with a probationary period can all trigger a re-assessment, even if the new income is higher.
A planned move within the same field, with confirmed permanent employment, is often workable — but only if the lender knows early and has the new offer letter and any confirmation it needs. Surprises are the problem, not change itself. Tell your broker the day a job change is even being considered. Remember, your approval was granted under the stress test your approval was actually granted under.
Can the property itself cause a problem?
Yes. The appraisal may come in below the purchase price, leaving a gap you must cover in cash or renegotiate. The lender or insurer may also flag condition or use issues — major structural concerns, certain heating or plumbing problems, or a property that does not match how it was described in the application.
That is why financing conditions exist: they give time for the lender and insurer to fully approve both you and the property before you are firmly committed. Removing conditions before that confirmation is complete is one of the riskiest moves a buyer can make. See the offer conditions that protect you while financing firms up.

How do document gaps delay or kill funding?
Lenders fund on documents, not intentions. Gaps in the down payment paper trail, an unexplained large deposit, expired income documents, or a gift letter that does not match the actual transfer can all hold a file at the final stage, when there is no time left to fix things calmly.
Keep every statement complete, including blank-looking pages if the lender asks for all pages, and send documents exactly as requested rather than cropped or partial. The First Home Guide for Edmonton lists the documents buyers are asked for most often, and a Mortgage Renewal Check style review of your file before conditions expire catches most gaps early.
What is the safest rule between offer and closing?
Freeze the picture you were approved on: no new debt, no job changes without a conversation, no large unexplained money movements, and no missed payments on anything. Keep your broker and realtor informed of anything that might change, however small it seems.
Approvals rarely fail because a lender changed its mind. They fail because the file changed.
