# How to Handle a Low Appraisal in Canada: Proven Strategies for 2026 Buyers > A low property appraisal can derail your mortgage approval — but it doesn't have to. This guide explains exactly what Canadian homebuyers and homeowners can do when an appraisal comes in below the purchase price in 2026: how to challenge the valuation, close the appraisal gap, understand your rights under OSFI (Office of the Superintendent of Financial Institutions) Guideline B-20, and navigate CMHC (Canada Mortgage and Housing Corporation) insured versus uninsured mortgage rules.

This guide walks you through every practical option available to Canadian buyers in 2026: from disputing comparable sales used by the appraiser, to increasing your down payment to bridge the gap, to requesting a second appraisal under your lender's review process. Whether you're buying your first home or refinancing, understanding how appraisals affect your loan-to-value (LTV) ratio — the percentage of the property's appraised value you're borrowing — is essential to protecting your purchase and your finances. - Know your appraisal gap options: if the appraised value is lower than the purchase price, you can increase your down payment to cover the shortfall, renegotiate the purchase price with the seller, or request a formal appraisal review — all before walking away from the deal. - Challenge inaccurate valuations with evidence: appraisers rely on comparable sales (comps), and if outdated or mismatched properties were used, you have the right to submit a rebuttal with stronger comps to your lender for reconsideration. - Understand how LTV (loan-to-value) ratio affects your mortgage: LTV is calculated using the appraised value, not the purchase price. A low appraisal raises your effective LTV, which can push you above the 80% threshold that triggers mandatory CMHC default insurance on insured mortgages (not uninsured). LTV = (mortgage amount ÷ appraised value) × 100. - Insured vs. uninsured mortgages respond differently to low appraisals: for CMHC-insured mortgages (less than 20% down), the appraised value caps your eligible loan amount directly. For uninsured mortgages, a low appraisal may require you to top up your down payment to stay within your federally regulated financial institution's (FRFI's) maximum LTV limits under OSFI Guideline B-20. - A realistic appraisal protects your long-term investment: overpaying relative to appraised value means your home equity starts lower than expected, which can limit your refinancing options and increase your financial exposure if property values soften. ## Strategy & FAQ This guide equips mortgage brokers with the regulatory framework and client-facing strategies needed to resolve low appraisal situations efficiently in 2026. It covers FRFI-specific appraisal override procedures under OSFI Guideline B-20, including when a lender may accept a second appraisal, how to document a formal appraisal dispute with comparable sales evidence, and the distinction between how low appraisals are handled for CMHC-insured versus uninsured mortgage files. Brokers will also find guidance on recalculating LTV after a revised appraisal, advising clients on down payment top-up strategies, and identifying when escalating to an alternative lender or monoline is the most practical path to closing. ### What happens if my property is appraised lower than my offer price? The lender will base your mortgage amount on the *appraised* value, so you'll need to cover the difference. FRFIs base mortgage amounts on your ability to repay and the property's value as security. Thorough property assessments mitigate risks, so FRFIs have valuation policies to protect themselves. - Lenders use different ways to figure out your home's value, balancing risk and cost. - Figuring out value can include a home visit, a professional appraisal, or using computer programs. - Your lender should have a way to double-check if the home's value seems off. - The home's value should match what similar homes are selling for and how much the bank could get if they had to sell it. ### Can I challenge a low appraisal? Yes, you can request a review or provide additional information to support a higher property value. FRFIs must have a framework to review and challenge valuation assumptions, so provide supporting documentation and comparable sales data. - Your lender should have a process to double-check the appraiser's work if the valuation seems off. - The appraiser your lender uses needs to be properly qualified to make sure they know what they're doing. - The appraisal needs to be done carefully and without influence from the lending decision. ### How does a low appraisal affect my loan-to-value (LTV) ratio and down payment? A lower appraisal increases your LTV ratio, potentially requiring a larger down payment. Your LTV ratio is your mortgage amount divided by the appraised property value. (LTV = mortgage amount ÷ appraised value × 100.) FRFIs adjust property value for LTV calculations and use conservative approaches in rapidly increasing markets. - Your lender looks at location, property type, and current market to determine your home's value for your mortgage. - If home prices are rising quickly in your area, your lender might use a more careful estimate of your home's value. - Your down payment needs to come from your own savings to ensure you can afford your mortgage. ### How do reverse mortgages handle low property values? Reverse mortgages are non-recourse loans with no term, so values are appraised independently and conservatively. FRFIs appraise the properties at regular intervals and monitor major urban centers for valuation trends. - To make sure your home's value is accurate, appraisals can't include guesses about future price increases. - Your lender should regularly check your home's value to make sure it reflects current market conditions. - Lenders must carefully review your mortgage application, including how long you plan to live there and potential changes to interest rates, to ensure you can afford your mortgage. ## Sources - Property appraisals — https://www.osfi-bsif.gc.ca/en/guidance/guidance-library/residential-mortgage-underwriting-practices-procedures-guideline-2017#2.4.2 - Property value used for the LTV ratio — https://www.osfi-bsif.gc.ca/en/guidance/guidance-library/residential-mortgage-underwriting-practices-procedures-guideline-2017 - Footnotes — https://www.osfi-bsif.gc.ca/en/guidance/guidance-library/capital-adequacy-requirements-car-guideline-2026
