Underwriters review mortgage applications to verify income, assets, debt, and credit history, ensuring the loan meets guidelines for approval. They validate property appraisals, confirm employment, and issue conditions for final approval, ultimately deciding whether to accept, suspend, or deny the loan before issuing a "clear to close".
Capacity. When trying to determine whether you have the means to pay off the loan, the underwriter will review your employment, income, debt and assets. They'll look at your savings, checking, 401k and IRA accounts, tax returns and other records of income, as well as your debt-to-income ratio.
Lying to your lender
If you rounded up or fudged a few numbers based on what you hope you will have by closing time, a discrepancy will pop up and the lender will ask for clarification. If you can't come up with proof of funds your application may get delayed or denied.
Credit reports showing late payments, collections, or significant derogatory events—such as bankruptcies or foreclosures—can signal financial mismanagement and complicate underwriting.
The lender verifies your income, checks your credit, and gives you a conditional approval letter that you can use when making offers. Underwriting happens after you've made an offer and submitted a full loan application. It's a detailed review that determines whether the lender will officially approve your mortgage.
Common reasons for mortgage denial include missing information on your loan application and not meeting minimum mortgage requirements. If your loan is denied in underwriting, you can double-check your paperwork, talk to your lender, explore other loan programs or find a cosigner.

Let's look at common reasons homes under contract fail to close and what to do to prevent this from happening to you.

Mortgage Approvals & Debts
Your total debt load plays a crucial role in determining whether you qualify for a mortgage and how much you can borrow. A high level of debt can either reduce the amount a lender is willing to offer or lead to outright rejection.
Understanding Mortgage Affordability in Canada
For insured mortgages in Canada, CMHC recommends a maximum GDS ratio of 39%. For a $90,000 salary (which breaks down to $7,500 per month), this means your housing costs shouldn't exceed $2,925 per month.
A mortgage application can be declined at almost any stage of the process – but this is highly unlikely after mortgage offer – and you can also be declined whether you're buying your first home, purchasing an investment property, moving home, or remortgaging.
Key Takeaways. Mortgages can fall through even after preapproval if finances change before closing. Big purchases or new credit can raise your debt ratio and lower your credit score. Employment changes may delay or deny final loan approval.
Your mortgage offer cannot be withdrawn after completion as the funds have already transferred. If you have a change in circumstances after completion, such as loss of income or redundancy, it's important to inform your lender as they should have options to support you and help you manage your monthly payments.
