5 Hidden Red Flags That Can Damage Your Mortgage Approval (It’s Not Just Credit Score)

Josh Perez • December 11, 2025

When most people think about getting denied for a mortgage, they assume the problem is a low credit score.
But in today’s lending environment, five lesser-known red flags are far more likely to derail your approval.

As a mortgage professional, I review hundreds of files every year — and these are the issues I see quietly hurting clients the most.


1. Payday Loans (Even Tiny Ones)

Even a short-term or small payday loan leaves a mark on your credit report.
To lenders, it signals financial strain or cash-flow pressure.


Why it matters:
Payday loan history can make lenders question your ability to manage monthly mortgage payments, even if everything else looks strong.


2. Gambling or Sports Betting Activity

If your bank statements show frequent betting charges, lenders may see it as a risk factor.


Why it matters:
It’s not about judging you — it’s about stability. Betting transactions can make lenders unsure about long-term money management habits.


3. Unpaid Taxes (Owing CRA)

This one is huge. Any outstanding balance with the CRA is treated seriously.


Why it matters:
Lenders know the government always gets paid first.
If CRA debt shows up, they’ll question whether your mortgage will truly be a priority.


4. Frequent Bank Overdrafts

Even with strong income, dipping into the negative too often can raise concerns.


Why it matters:
Overdraft patterns suggest inconsistent cash flow or a lack of financial cushion.
Lenders look closely at 90 days of banking — and overdrafts stand out.


5. Co-Signing Loans for Someone Else

You may not be making the payments… but lenders treat that debt as if you are.


Why it matters:
Co-signed loans directly reduce your borrowing power and lower your maximum approval amount.


If One of These Red Flags Applies to You… Don’t Panic

Having these on your file doesn’t mean you can’t get approved.
It simply means we need a strategy.


I help clients build personalized action plans to strengthen their file, improve their approval odds, and position them to purchase sooner.

If the title of this article caught your attention, chances are your family is growing. Congratulations. If you’re thinking now is the right time to move into a home that better fits your growing family—but you’re unsure how parental leave affects your ability to qualify for a mortgage—you’re in the right place. Here’s the good news. Qualifying for a mortgage while on parental leave is possible when it’s done correctly. When you work with an independent mortgage professional, lenders can often qualify you based on your return-to-work income , as long as you can provide documentation confirming you have guaranteed employment waiting for you. A word of caution If you walk into a bank branch and disclose that you’re currently on parental leave, there’s a chance the bank will only allow you to qualify using your parental leave income. That can significantly reduce your borrowing power. Parental leave income is typically limited to 55% of your previous earnings, up to a weekly maximum. Qualifying on that amount alone can restrict your options and impact the type of home you can purchase. Why lender choice matters One of the biggest advantages of working with an independent mortgage professional is choice . You’re not limited to one lender’s rules or products. Some lenders will allow you to qualify using 100% of your confirmed return-to-work income , which can make a meaningful difference in your approval amount and overall options. What you’ll need to qualify Most lenders will require an employment letter that includes: Employer name (preferably on company letterhead) Your job title Original start date (to confirm probation has been completed) Confirmed return-to-work date Guaranteed salary upon return Lenders want reassurance that your income will resume once parental leave ends. You may also be asked to provide income history from the past couple of years, which is standard for most mortgage applications. One important note Whether or not you actually return to work after parental leave is entirely your decision. From a mortgage perspective, qualification is based on having a confirmed position available to you at the time of approval. If you have questions about qualifying for a mortgage while on parental leave—or anything mortgage-related—please connect anytime. I’d be happy to walk you through your options and help you plan with confidence.
