You just won a bidding war in Oakville. You celebrated with a nice dinner and told the kids which bedrooms are theirs. Then the bank calls and says the house isn’t worth what you paid. This is the reality of the 2026 spring market where prices are moving faster than the paperwork can keep up.

We’ve been helping GTA families through these exact moments since 1988, so don’t panic yet. We know how to bridge that gap without losing your deposit or your sanity.

What is a low mortgage appraisal?
When you buy a home in Richmond Hill or Vaughan, your lender hires a professional appraiser. This person’s job is to tell the bank what the house is actually worth. They aren’t looking at how much you love the kitchen or the fact that there were twelve other offers on the table. They look at facts, square footage, and what the house next door sold for three months ago.
If you agreed to pay $1.2 million but the appraiser says it’s only worth $1.1 million, you have a $100,000 problem. The bank will only lend you a percentage of the $1.1 million valuation. That leftover $100,000 is what we call a mortgage shortfall. You’re responsible for finding that extra cash before closing day. It doesn’t matter if you already have a pre-approval. The final loan is always tied to the property value, not just your credit score.
Why the GTA bidding wars cause an appraisal gap Canada
The 2026 spring market is moving at a breakneck pace. TRREB reported a 6.2% month-over-month increase in average GTA home prices in March 2026. When prices jump that fast, appraisers struggle to justify the new numbers. The Appraisal Institute of Canada (AIC) notes that appraisals are based on historical sold data. This data can trail real-time bidding war prices by several weeks. By the time you win a house in Hamilton or Milton, the “comparable” sales the appraiser is using are already outdated.
CREA data shows the GTA sales-to-new-listings ratio hit 65% in April 2026. This level is historically associated with price-appraisal disconnects. There are too many buyers chasing too few houses in places like Ajax and Oshawa. This competition pushes prices up, but the appraiser is stuck looking in the rearview mirror. They see what happened in February while you’re paying May prices. This creates the dreaded appraisal gap Canada buyers are currently fighting.
The Math of the Shortfall
Let’s look at how this actually hits your wallet. If you’re putting 20% down, you might think a small dip in appraisal doesn’t matter. But the bank calculates your loan-to-value (LTV) ratio based on the lower number. You can see how the numbers shift in the table below.
| Scenario Details | Expected (Offer Price) | Actual (Low Appraisal) |
|---|---|---|
| Purchase Price | $1,000,000 | $1,000,000 |
| Appraised Value | $1,000,000 | $940,000 |
| Max Loan (80% LTV) | $800,000 | $752,000 |
| Required Down Payment | $200,000 | $248,000 |
| Cash Gap to Fill | $0 | $48,000 |
In this example, a $60,000 drop in appraisal results in a $48,000 cash shortfall. You need that money on top of your original down payment. If you’re already stretching your budget for a home in Whitby or Burlington, that extra fifty grand might not be sitting in your sock drawer.
The OSFI LTI cap: Why you can’t just borrow more
In the old days, if an appraisal came in low, we might have been able to just tweak the mortgage amount. But OSFI’s 2026 Loan-to-Income (LTI) caps changed the game. Lenders are now strictly limited on how many high-ratio loans they can carry that exceed 4.5 times a borrower’s annual income. This means if you’re already at your max borrowing limit, the bank literally cannot give you more money to cover the gap.
And it gets tougher. You also have to deal with the mortgage stress test which qualifies you at a much higher rate than you’ll actually pay. Between the LTI caps and the stress test, your wiggle room is almost zero. This is why having a broker who understands what you need to know now about market shifts is vital. We don’t just look at the rate. We look at the total capacity of the lender to actually fund your deal when things go sideways.
How to fix a low mortgage appraisal and close your deal
So, you’re staring at a shortfall. What’s next? First, we can challenge the appraisal. If we can find better comparable sales in Toronto or Markham that the appraiser missed, we might get the number bumped up. It’s a long shot, but we’ve done it before. We’ve been in Brampton since 1988, and we’ve seen every trick in the book.
If a value change isn’t happening, we look at your down payment. You might need to pull from your RRSP under the Home Buyers’ Plan or ask for a gifted down payment from a family member. But if the big banks are being stubborn because of those LTI caps, we look at other options. Sometimes a B-Lender Mortgage is the best path forward. These lenders are often more flexible with their valuations and aren’t always bound by the same rigid LTI restrictions as the Big Five banks.
But remember, these are temporary fixes. You want to get into the house first. Once you’re in, we can look at your long-term strategy, especially when it comes time for renewing your mortgage. Our goal is to make sure you don’t lose your deposit. Losing a $50,000 deposit because you couldn’t close is way worse than paying a slightly higher rate for a year or two.

Frequently Asked Questions
Can I use a different appraiser if the first one is low?
Usually, the lender chooses the appraisal company, and you can’t just pick your own. However, we can sometimes move your file to a different lender who uses a different appraisal firm. This can result in a fresh perspective and potentially a higher valuation for your property.
What happens to my deposit if I can’t cover the appraisal gap?
If you can’t secure financing because of an appraisal shortfall and you didn’t have a financing condition, you risk losing your entire deposit. Additionally, the seller could sue you for the difference if they end up selling the house for less than your original offer. This is why having a solid backup plan is essential.
Do LTI caps apply to all lenders in Canada?
The OSFI LTI caps primarily apply to federally regulated financial institutions like the big banks. Many credit unions and alternative lenders are provincially regulated and may have more flexibility. We use our 40+ lender relationships to find these alternatives when the big banks say no.
Should I always include a financing condition in a bidding war?
In a perfect world, yes, but in a hot GTA market, a financing condition often means your offer gets tossed in the trash. If you choose to go firm, you must be confident in your ability to cover a potential low mortgage appraisal with extra cash or alternative lending options. We help you assess that risk before you submit your bid.
