Appraisal Shortfall Guide for Ontario Realtors

An appraisal shortfall occurs when the value accepted for lending purposes is lower than the purchase economics the buyer expected. AIC explains that when a home is bought, the amount of mortgage available can be based on appraised value and that paying materially more than appraised value may mean the borrower cannot obtain the full loan amount anticipated.

The practical result is not always a dollar-for-dollar increase in down payment; the impact depends on the lender, mortgage-insurance structure and loan-to-value limits. But the core problem is consistent: the lender will not automatically finance a price simply because the buyer agreed to pay it.

Appraisals are evidence-based opinions of market value prepared for a specific client, often the lender. AIC notes that the lender or insurer decides whether an appraisal is required and what scope is appropriate. A shortfall can arise when recent comparable sales do not support the bid, the market moved rapidly, the property is unusual, renovations are difficult to quantify, the property has legal or physical characteristics affecting marketability, or the appraisal scope reveals facts not apparent in the listing.

An appraisal is not designed to validate a negotiation outcome. The appraiser's duty is to the appraisal assignment and intended user, not to the buyer, seller or Realtor's target price.

A Realtor can help the process by making accurate property information easy to verify: complete MLS data, permitted improvements where known, relevant recent comparable sales, leases where rental income is material, floor plans and details of features that may not be obvious. AIC encourages clear property details and access information early while preserving appraiser independence.

Do not pressure the appraiser toward a number or present selective information as though the appraiser is required to accept it. If factual errors are suspected, route a reconsideration request through the lender or mortgage professional using objective evidence.

Potential responses may include increasing the buyer's cash contribution, revisiting price with the seller, correcting factual appraisal errors, obtaining a second appraisal where the lender permits it, changing lender strategy, or restructuring the mortgage. Each option has timing, cost and qualification consequences.

If the purchase is still conditional, the Realtor and buyer should review the contract and legal options before any deadline. If the purchase is firm, involve the buyer's lawyer immediately because inability to fund can become a contractual default issue.

Before a buyer bids materially above recent comparable evidence, ask the mortgage professional to model a lower-value scenario. The useful question is: if lending value is $25,000, $50,000 or $100,000 below the price, what additional cash might be required and does the buyer actually have it after closing costs?

That scenario planning turns appraisal risk from a surprise into an explicit offer decision.
