The Hidden Problem with Relying on the Sale Price in Estate Valuations

In many estate files, it seems like the simplest solution:

“Just use the sale price.”

After all, what better evidence of value could there be than what someone actually paid?

The property was exposed to the market. A buyer made an offer. The deal closed.

It feels definitive.

But in estate valuation, relying on the sale price can quietly introduce risk —the kind that often surfaces later, when it is much harder to correct.

Because in many cases, the sale price answers the wrong question.

Sale Price vs. Fair Market Value: Not Always the Same

For tax reporting purposes, the Canada Revenue Agency requires that real estate be valued at its fair market value as of the date of death.

That’s a very specific standard.

It assumes:

• A willing buyer and seller

• Neither under pressure

• Full exposure to the market

• Reasonable knowledge of the property

A sale price, however, reflects what happened at one moment in time under specific conditions.

And those conditions are not always aligned with fair market value at the required date.

The Timing Gap: When Months Change the Story

One of the biggest issues is timing.

In most estates:

• The date of death occurs first

• The property is listed later

• The sale happens even later

In a changing market, even a few months can make a meaningful difference.

• Rising market → sale price may be higher than date-of-death value

• Declining market → sale price may be lower

Without proper analysis, using the sale price can unintentionally:

• Overstate value

• Understate value

• Trigger tax or beneficiary disputes

The sale price reflects when the deal happened — not necessarily when the value needs to be determined.

The Conditions of Sale: What the Price Doesn’t Tell You

A sale price is not just a number —it is the result of a negotiation.

And not all negotiations happen under ideal conditions.

Factors that can influence sale price include:

• Urgency from the executor to sell quickly

• Limited marketing exposure

• Multiple offers driving price upward

• Poor listing strategy or timing

• Property condition at time of sale

These factors can distort the result.

A high price does not always mean the property was worth more. A low price does not always mean it was worth less.

It simply reflects what happened in that specific transaction.

The Renovation Effect: When the Property Changes After Death

Another hidden issue arises when the property is improved before sale.

Executors may:

• Renovate kitchens or bathrooms

• Repair deferred maintenance

• Stage or enhance presentation

These changes can significantly increase the eventual sale price.

But the critical question becomes:

Was the property worth that amount at the date of death, or only after improvements?

Without properly separating these timelines, the sale price can create a misleading benchmark.

The Risk of “Hindsight Bias”

Relying on the sale price introduces a subtle but powerful problem:

Hindsight bias.

Once the sale price is known, it becomes difficult to ignore.

It influences perception.

• If the sale price is higher → earlier valuations may seem “too low”

• If the sale price is lower → earlier valuations may seem “too high”

But a proper valuation must be based on:

• What was known at the valuation date

• Market data available at that time

—not what happened later.

A defensible appraisal separates evidence from outcome.

When Sale Price Triggers Challenges

Many estate disputes begin with a simple question:

“If it sold for this, why wasn’t it valued at that?”

This can come from:

• Beneficiaries questioning fairness

• Accountants reviewing tax filings

• The Canada Revenue Agency during a review

If the valuation relies heavily on the sale price without proper explanation, it can appear:

• Arbitrary

• Unsupported

• Retrospectively adjusted

That is often when challenges gain traction.

What a Defensible Approach Looks Like

A well-prepared estate appraisal does not ignore the sale price.

But it treats it carefully — as one data point, not the foundation.

It:

• Anchors the value to the correct valuation date

• Uses comparable sales from the relevant period

• Reconstructs market conditions at that time

• Explains any differences between valuation and eventual sale

• Documents property condition at the valuation date

This approach answers the right question:

“What was the property worth at that specific point in time — independent of what happened later?”

Why Some Files Become Difficult

When sale price is used incorrectly, common problems emerge:

• Confusion between market value and transaction outcome

• Lack of support for retrospective valuation

• Inability to explain differences between valuation and sale

• Increased risk of CRA scrutiny

• Heightened potential for beneficiary disputes

These issues often do not appear immediately.

They surface later — when the file is reviewed or challenged.

Final Thought: The Sale Price Feels Certain — But It Can Mislead

The sale price is powerful because it feels real.

But estate valuation is not about what happened eventually.

It is about what was supportable at the required date, under the right conditions.

When that distinction is overlooked, even a seemingly straightforward file can become complicated.

When it is handled properly, the valuation becomes far more difficult to challenge — regardless of the sale outcome.

Need an Estate Appraisal That Can Stand on Its Own — Not Just the Sale Price?

In estate matters, the strength of the valuation is not in the number alone —it is in how well that number can be supported, explained, and defended.

A properly prepared appraisal ensures that the value holds up even when the sale price tells a different story.
