The Hidden Risk of Using a Realtor Opinion Instead of a Formal Estate Appraisal

In many estate files, executors initially ask a simple question:

“Do we really need a formal appraisal, or can we just use a realtor’s opinion of value?”

At first glance, relying on a realtor opinion may seem practical:

• it is often faster,

• less expensive,

• and easier to obtain.

But in contested estate matters, the hidden risks of relying solely on a realtor opinion can become significant — particularly when:

• beneficiaries disagree,

• CRA reviews the file,

• or the property value is challenged years later.

For estate lawyers, this distinction is critically important because not all valuation documents are designed for the same purpose.

And when the wrong valuation tool is used in the wrong context, the estate can quickly become vulnerable to disputes.

Why Realtor Opinions Are Common in Estate Files

Realtors frequently provide:

• comparative market analyses (CMAs),

• listing guidance,

• and general opinions about current market conditions.

These opinions can be useful for:

• pricing strategy,

• understanding buyer demand,

• and preparing a property for sale.

In cooperative estate matters with minimal risk of dispute, this may initially appear sufficient.

The problem arises when the valuation later becomes:

• legally scrutinized,

• questioned by beneficiaries,

• or reviewed by CRA.

That is when the limitations of informal valuation evidence often become much more significant.

Realtor Opinions and Formal Appraisals Serve Different Purposes

One of the biggest misconceptions in estate administration is believing:

“A realtor opinion and a formal appraisal are basically the same thing.”

In reality, they are typically prepared for very different purposes.

A realtor opinion often focuses on:

• current listing strategy,

• buyer psychology,

• pricing competitiveness,

• and marketability.

A formal estate appraisal, however, may involve:

• retrospective market analysis,

• date-of-death valuation,

• comparable sales adjustments,

• defensible methodology,

• and legally relevant valuation standards.

The difference becomes especially important in:

• probate matters,

• CRA reviews,

• litigation-sensitive files,

• and disputed estates.

Retrospective Estate Values Are Often the Most Difficult

Many estate files require valuation as of:

• the date of death,

• a historical transfer date,

• or another legally relevant retrospective date.

This is very different from estimating what a property might list for today.

Retrospective appraisals require reconstruction of:

• historical market conditions,

• buyer behaviour at the time,

• comparable sales from the relevant period,

• and market trends affecting value at that date.

In rapidly changing GTA markets, even a few months may materially affect value conclusions.

This is one reason retrospective valuations are often heavily scrutinized when disputes emerge.

Beneficiaries Often Challenge Informal Valuation Evidence

In many contested estates, beneficiaries eventually begin comparing:

• online estimates,

• neighboring sales,

• current listing prices,

• realtor opinions,

• and retrospective appraisals.

Once different values begin circulating, conflict can escalate quickly.

Beneficiaries may question:

• whether the estate property was undervalued,

• whether the sale process was fair,

• or whether the executor obtained proper valuation evidence.

If the estate relied primarily on an informal opinion, beneficiaries may argue:

the valuation process itself was insufficient.

At that point, the estate may need:

• a formal retrospective appraisal anyway,

• often after conflict has already intensified.

CRA Reviews Can Create Additional Exposure

One of the hidden risks executors often overlook is that estate values may still be questioned years later.

When CRA reviews a file, the focus is usually not simply:

“What number was reported?”

The more important question becomes:

“How was that number determined?”

CRA may examine:

• comparable sales support,

• retrospective market analysis,

• valuation methodology,

• effective dates,

• and overall defensibility.

Informal opinions prepared primarily for listing guidance may not always contain the level of analysis needed for:

• retrospective tax review,

• reassessment disputes,

• or litigation-sensitive matters.

Sale Price Alone Does Not Always Solve the Problem

Executors sometimes assume:

“If the property eventually sold, then the sale price proves the value.”

But in many estate disputes, beneficiaries continue challenging the value even after the sale closes.

They may argue:

• the property was underpriced,

• the market changed,

• the home sold too quickly,

• or the valuation date was different from the eventual sale date.

This is especially common in:

• appreciating markets,

• delayed estate administrations,

• and emotionally charged family disputes.

The key legal question often becomes:

“What was the fair market value at the legally relevant date?”

—not simply what the property later sold for.

Courts Usually Focus on Methodology and Defensibility

Courts generally understand that valuation is not an exact science.

Two professionals may reasonably disagree.

The key issue is often whether:

• the methodology was appropriate,

• comparable sales were properly analyzed,

• adjustments were supported,

• and the valuation process itself was defensible.

A strong formal appraisal typically provides:

• detailed market analysis,

• transparent reasoning,

• retrospective support when necessary,

• and logical reconciliation of value conclusions.

The goal is not proving the number was “perfect.”

The goal is demonstrating that the process behind the valuation was credible and supportable.

Why This Matters for Estate Lawyers

Weak valuation evidence can lead to:

• beneficiary disputes,

• delayed estate administration,

• competing appraisals,

• CRA reassessments,

• executor liability concerns,

• and increased legal costs.

A defensible retrospective appraisal may help:

• support executor decision-making,

• reduce speculation,

• strengthen tax reporting,

• improve defensibility,

• and narrow disputes before they escalate.

In many estate matters, the quality of the valuation evidence directly affects how smoothly the estate administration proceeds.

Final Thoughts

Realtor opinions can provide useful market insight.

But estate lawyers must often evaluate whether:

• the assignment requires pricing guidance,

  
  

  or:

• defensible valuation evidence capable of withstanding scrutiny later.

Because the hidden risk is not necessarily the opinion itself.

The real risk is discovering years later — after beneficiaries or CRA begin asking difficult questions — that the valuation evidence was never designed for that level of scrutiny in the first place.

For estate lawyers, obtaining the right type of valuation from the beginning can often help prevent:

• larger disputes,

• delayed administration,

• and expensive challenges later on.
