Yes, a mortgage can absolutely fall through during underwriting, even after a pre-approval. Underwriting is the final, detailed verification of your finances and the property, with roughly 1 in 10 applications being denied at this stage. Common causes include new debts, employment changes, low appraisals, or issues with documentation.
So, how often does an underwriter deny a loan? In 2023, about 9.4% of all home purchase applications were denied, according to data from the Consumer Financial Protection Bureau. That means just under 1 in 10 mortgage applications didn't make it past underwriting. Denial rates vary by loan type, though.
Even if you've been preapproved, you're not guaranteed a mortgage. Underwriting is the final and most detailed review stage—and changes to your finances or documentation issues can still result in a denial.
A mortgage underwriter may decline your application due to your income not meeting lending policy rules. For example, if a large proportion of your income is made up of non-guaranteed sources, the underwriter may cap the proportion of this they use in their affordability calculations.
Any missing data in the application form such as a signature, a figure, or a document, can prevent the underwriting process from moving along. An application with complete information is essential to begin a loan approval process.
Credit reports showing late payments, collections, or significant derogatory events—such as bankruptcies or foreclosures—can signal financial mismanagement and complicate underwriting.
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.
The underwriter determines your ability to repay the loan, looking at financial stability, and the value of any collateral noted. After completing the assessment, the underwriter will approve, deny, or suspend your application dependent on additional information.
The 3-7-3 Rule in mortgages isn't a loan type but a federal timeline from the TILA-RESPA Integrated Disclosure (TRID) rule, ensuring borrower protection by mandating disclosures within 3 business days of application, a 7-business-day wait between the initial Loan Estimate and closing, and another 3-day wait if significant changes (like APR) occur, giving borrowers time to review costs before committing to a loan.
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.
Credit score is the most important factor in determining mortgage approval, but your income and debt levels, as well as the size of the loan vs. the home's value, are also major factors.
Yes, you can likely get a $50,000 loan with a 700 credit score, as this falls into the "good" credit range (670-739) that unlocks better rates, but approval also hinges on your income, debt-to-income (DTI) ratio (ideally below 36%), and overall credit history, with lenders looking for stability and repayment ability, so prequalifying with multiple lenders helps compare terms.
Putting down 20% of the home's purchase price is a traditional down payment option. For a $400,000 home, a 20% down payment would be $80,000. This option may help you avoid private mortgage insurance (PMI) and can lead to more favorable loan terms.
Yes. Even after you've been pre-approved, underwriters may do a final check on your bank statements for a mortgage before closing. If they spot any last-minute red flags — like a massive withdrawal, new debt, or a sudden job change — you could lose your approval.
The 3 C's of underwriting, primarily used in lending, are Credit, Capacity, and Collateral, which underwriters assess to evaluate a borrower's risk by examining their credit history (Credit), ability to repay from income (Capacity), and the value of the asset securing the loan (Collateral). For surety bonds, the "C's" can shift to Character, Capacity, and Capital, focusing on trustworthiness, ability to perform, and financial strength.
Risky spending habits
But frequent and large transactions to betting shops or gambling sites can be a major red flag. It suggests risky spending habits, which may raise concerns on whether you'll prioritise mortgage repayments.
