Why Your Home's Selling Price, Appraised Value and Tax Assessment Are Different
One home can have a $795,000 asking price, a $750,000 bank appraisal and a $715,000 municipal assessment—all without a mathematical mistake.
That can surprise buyers, homeowners and builders. If the property is the same, shouldn't it have one clear value? The answer is that different numbers measure different things: an asking price is a marketing decision, a sold price is a transaction, an appraisal supports valuation for financing, and a municipal assessment is calculated under legislation for property taxation.
At Kapish Learning Center, brought to you by Kapish Homes, we want readers to recognize what each number means before relying on it. Understanding the difference helps you negotiate realistically, respond to appraisal gaps, evaluate upgrades and explain why the cost of construction does not automatically become resale value.
Part One — Four numbers, four different questions
One property. Four figures. None automatically replaces the others.
A home has no single universal number that answers every financial question. Asking price is a seller's position; sale price records the agreed transaction; an appraisal supports a valuation for a defined purpose; and a municipal assessment allocates property taxes under a legislated process.
An asking price is an invitation to negotiate, not proof of market value.
The sold price records a particular agreement at a particular time, subject to its circumstances.
Each performs a different valuation exercise for a different purpose and reference date.
Part Two — The advertised and the negotiated
Asking price and selling price are not synonyms.
An asking price is the amount a seller markets the home for. It may reflect recent comparable listings and sales, the property's features, negotiation strategy, available inventory and the seller's preferred timing. It can be below, at or above what the market ultimately supports. A carefully presented new build may command attention, but its list price is still a proposal.
The actual selling price is what a buyer and seller agree to in the completed transaction. It depends on the offers available, financing and inspection conditions, timing, included items and other negotiated terms. It is a historical transaction fact, though it is not guaranteed to equal a neutral market-value estimate.
For example, a seller may list a property at $795,000, then accept $770,000 after comparing current buyer interest and competing homes. That does not necessarily mean the original list price was deceptive, nor does it establish the value of every similar home. A buyer considering the property should compare recent sold prices, not just the prices currently displayed online.
Part Three — Valuation for financing
What does a professional home appraisal actually examine?
Comparable homes help anchor the estimate.
A professional appraisal is an opinion of a property’s value as of a particular date, for a defined purpose. A lender may require one for a purchase, refinance or other credit decision. CMHC explains that an appraisal can consider the property’s physical and functional characteristics, recent comparable sales and current local market conditions.
Comparable sales are rarely identical. An appraiser may examine location, living area, lot size, age, condition, construction quality, garage, basement development and other amenities. Adjustments help account for differences between the subject home and the selected comparables. The result is an evidence-based estimate—not a guarantee of the future selling price.
Appraisals can also vary over time as mortgage conditions, inventory and comparable transactions change. A well-documented upgrade may support value if buyers in that submarket are willing to pay for it, but a costly or highly personal selection does not automatically receive a dollar-for-dollar adjustment.
Part Four — Municipal assessment for taxation
Edmonton's assessed value has an earlier reference date.
A tax assessment is not a live asking-price calculator.
Edmonton uses mass appraisal to estimate property values annually for taxation. Rather than appraising every home individually for a sale that day, the City analyzes large groups of properties using sales records and attributes such as size, year built, garage, basement finish, condition and neighbourhood.
For a 2026 property assessment, the market valuation date is July 1, 2025, while the property’s physical condition is considered as of December 31, 2025. A home marketed or financed in October 2026 is being considered at a different point in time. Market changes, new construction and updates to records help explain why its tax assessment may not match a present-day deal.
The assessed value is intended to represent market value at the legislated date; it is not inherently an undervaluation or an instruction for what a seller must charge today. Edmonton also issues supplementary assessments where new construction adds taxable value during the current taxation year.
Part Five — Value versus tax bill
Your assessment helps calculate property tax, but it is not the tax bill.
Edmonton issues assessment notices and tax notices separately. The annual assessment notice states the value used for municipal taxation. The later tax notice shows the amount owing, including municipal and provincial education property-tax components and any applicable special charges.
Residential property tax is based on the taxable assessed value and the tax rates adopted for that tax year. Those rates can change with municipal budgets, provincial education requisitions and shifts in the assessment base. Therefore, a higher assessment does not always translate to an identical percentage increase in tax; what matters is both the property’s change relative to other properties and the adopted rates.
Review your property's details in Edmonton’s assessment resources or MyProperty account. If the assessed data includes the wrong square footage, garage or completion status, contact the City promptly. Formal review windows and deadlines apply; disputing an assessment does not suspend the requirement to pay property taxes by the due date.
Part Six — When the lender sees a different number
An appraisal gap can affect a mortgage, even with an accepted offer.
An accepted price does not guarantee the lender will finance it.
Suppose a buyer negotiates a $770,000 purchase, while the lender’s appraisal comes in at $750,000. The agreement may still be valid, but the lender may calculate the available loan using its supported value and underwriting policies. This can create a financing shortfall that must be resolved before closing.
The $20,000 difference is the appraisal gap in this hypothetical example. It is not necessarily the precise extra cash required: the result depends on the permitted loan-to-value ratio, mortgage-insurance rules, down payment and lender criteria. Options might include revisiting the purchase terms, adding qualifying funds or arranging acceptable financing with the lender.
Mortgage pre-approval alone is not a guarantee that a particular property will satisfy final lending requirements. The Real Estate Council of Alberta cautions that low appraisals can create funding challenges and encourages buyers to understand the risks of unconditional offers.
Part Seven — Refinancing and home equity
The appraisal can matter again after you have moved in.
A homeowner refinancing a mortgage may expect the bank to use the asking price of similar listings or the amount spent on renovations. Instead, the lender may establish an updated property value using its own valuation process, including an appraisal where required. Available borrowing depends on the recognized value, mortgage balance, qualifying income, credit and loan-to-value rules.
For instance, putting $60,000 into a kitchen and bathroom does not automatically increase the bank’s value by $60,000. Some improvements may improve marketability, comfort and buyer appeal without producing matching resale gains. Others may bring an outdated home closer to the local standard and have meaningful market impact.
If a family renovates mainly for daily enjoyment, financial return may be secondary. If an investor or builder is planning a project primarily around resale or refinancing, conservative comparable-sale evidence is essential. This is especially important for specialized upgrades, unusual floor plans and premium finishes in neighbourhoods where typical buyers may not pay the full replacement cost.
Part Eight — Building economics
Why higher construction cost does not promise higher resale value.
Cost creates the home; the market determines what buyers pay.
The cost of building includes land, site preparation, permits, foundation, labour, materials, mechanical systems, financing, overhead and many finishing decisions. A custom home can cost more because of difficult ground conditions, architectural complexity or very specific selections. These expenses are real, but prospective buyers do not automatically reimburse them.
In the resale market, buyers compare available alternatives. They may value a legal suite, an efficient floor plan, location, a larger garage or high-quality windows, but not every dollar spent is visible, necessary or meaningful to them. Local comparable homes establish practical limits on what the market may support.
For a smaller builder, the lesson is to evaluate the expected selling price independently from the project cost estimate. That means analyzing comparable completed sales, realistic financing and selling expenses, carrying costs and contingency before assuming an attractive margin.
Part Nine — Before trusting a property number
Eight questions that make valuation discussions clearer.
Is this asking, sold, appraised or assessed value?
Identify whose number it is, what decision it supports and the date it applies to.
Which comparable sales support the estimate?
Ask how size, lot, location, age, condition and features compare to recent sold properties.
When was the property assessed?
Edmonton's municipal assessment uses previous-year valuation and condition dates.
Does the assessment record describe the home correctly?
Confirm basement development, garage, finished area and property characteristics.
Will a lender require an appraisal?
Discuss financing conditions and the possibility of an appraisal lower than the purchase price.
Are upgrades reflected in comparable buyer demand?
Separate improvement costs from what similar homes actually sell for in this location.
Could new construction change the tax bill?
Ask about supplementary assessments and municipal property-tax timing.
What is the all-in financial outcome?
Account for purchase or build cost, mortgage terms, GST if applicable, selling costs and market risk.
