Trust Property Appraisals Done Wrong Cost Heirs Thousands

Real estate is often the most valuable asset in an estate. While valuing a property might seem straightforward, an appraisal can fail to capture its full market value. This is especially true for trust properties that have been held for decades.

When a family home has not sold in 60 years, an appraiser may have limited recent transaction history for the property itself. That can lead to a valuation that falls below what the property could command in the current market. If the property later sells for more than its estate value, the difference can create a higher taxable capital gain.

A submarket specialist can identify the local factors that influence value and provide a useful benchmark before the estate appraisal is finalized. That additional perspective can help the estate establish a more accurate value and potentially reduce unnecessary tax exposure.

What Trustees Get Wrong Before the Appraisal Is Filed

When a parent dies and a child becomes trustee, the instinct is to follow the accountant's checklist. Get the property appraised, establish the estate's value, then call a real estate agent.

Following the accountant's advice makes sense. However, that checklist may put things in the wrong order for some trust properties. The financial consequences may not become apparent until the property sells.

The appraisal supports the property's fair market value for tax purposes. If the property later sells for significantly more than its established basis, the difference may create a taxable capital gain. That risk increases when the initial appraisal falls well below the property's true market value.

The fix is simple but time-sensitive: before the estate appraisal is finalized, consult someone who knows what the property is worth in today's market.

A Case Where the Numbers Tell the Story

A longtime family friend came to me after their parents had passed. The home had not been on the market in 60 years. An appraiser had already been brought in and the number generated, but the estate hadn't finalized it yet.

One question settled the direction: had they committed to that appraisal yet? They hadn't, and that brief window before finalization changed the entire outcome.

I brought in an appraiser who specialized in the specific submarket, referred through a land use attorney who knew the property and the client. The result shifted the entire outcome of the estate settlement.

"The appraisal came in at six hundred thousand. I knew someone who did a lot of appraising in the area. He appraised it at seven fifty, and I ended up selling it for seven seventy-five. If you do the real estate cost of that transaction, it netted them about seventy-five thousand more than the original appraisal suggested. And it was appraised at time of death at seven fifty, so it had no taxable event to the estate." – Scott Union, Broker Associate, Compass – Union West RE Group

Trust Properties Often Get Undervalued by the First Appraiser

The reasons a first appraisal comes in low on a long-held trust property are predictable once you know what to look for. General appraisers who rely on county records and broad comparable sales data often miss the nuances that drive value in tightly defined luxury submarkets.

A property in the Rancho Santa Fe Covenant, a bluff-adjacent lot in La Jolla, or a parcel in Del Mar demands carefully selected comparable sales. Broad regional comps often fail to capture their unique value. Those comps must account for orientation, lot usability, and school district access. These factors rarely surface in automated valuations or broad regional data pulls.

A home that hasn't transacted in decades also has no recent sales history to anchor the appraiser's analysis. The appraiser is working from what sold nearby, not from what this specific property would generate in a properly managed, network-driven sale. Those are two different numbers, and the gap between them is exactly where the estate's tax exposure lives.

In markets like Rancho Santa Fe and Del Mar, differences of over $100,000 between a general appraisal and a submarket specialist's figure are not unusual. The California State Board of Equalization notes that estate property valuations must reflect fair market value at the date of death. The responsibility for ensuring that accuracy falls on whoever ordered the appraisal.

How to Protect the Estate Before the Appraisal Is Set

The trustee's job is to protect the beneficiaries, and that includes protecting them from a low estate appraisal that creates an unnecessary tax burden. What many don't realize is that trustees have significant latitude.

The estate is not obligated to accept the first number that comes in. Commissioning a second appraisal from a local market specialist is standard estate administration practice.

The sequence that best serves the estate starts before the appraisal is finalized. Bring in a broker with genuine local expertise to prepare a current market analysis based on recent, relevant transactions. If that analysis differs significantly from the appraiser's figure, commission a second appraisal from someone who specializes in that submarket.

"I said, don't finalize it. Because the appraised value your appraiser came up with is wrong. If that's what you set the estate at, and I sell it for a million dollars more, you're going to be taxed on that. So before you set that value, let me do a market analysis. Tell you what that value should be. Then perhaps consult a different appraiser, one more specialized in that area." – Scott Union, Broker Associate, Compass – Union West RE Group

Not sure whether an estate appraisal reflects true local market value? Reach out to the team at Compass – Union West RE Group before that number is filed. A market analysis at this stage costs nothing and may protect the estate from a significant and entirely avoidable tax event.

What a Well-Grounded Appraisal Does for the Sale Itself

Beyond the tax benefit, an estate appraisal that reflects genuine market value gives the sale itself a stronger foundation. The broker and the buyer negotiate from a confirmed, specialist-verified figure. There is no ambiguity about whether the asking price is defensible.

Understanding the Uniform Standards of Professional Appraisal Practice (USPAP) is useful context here. USPAP requires appraisers to use the most relevant comparable sales data available. When an appraiser lacks local transaction history, meeting that standard becomes more difficult. The estate's attorney or trustee can raise the issue before the appraisal is filed.

FAQs About Trust Property Appraisals

What is a stepped-up basis and why does it matter for an estate sale?

When a property owner dies, heirs typically receive a stepped-up cost basis equal to the property's fair market value at the date of death. This resets the baseline for calculating capital gains. If the property then sells at or near that stepped-up value, the taxable gain is minimal. An undervalued estate appraisal sets that baseline too low and exposes the estate to avoidable tax on the difference.

Can a trustee challenge an appraisal that has already been completed?

Yes, as long as the appraisal has not been filed or finalized with the estate. Trustees have a fiduciary duty to protect beneficiaries, which includes ensuring the property is accurately valued. Commissioning a second appraisal from a local market expert is a standard and legitimate step.

How much can two appraisals differ on the same property?

On long-held trust properties in tightly defined luxury submarkets, the spread can be significant. A general appraiser working from broad regional comps may miss relevant factors. These factors include lot orientation, school district access, or buyer demand specific to that neighborhood. Differences of $100,000 to $200,000 or more are not uncommon in markets like Rancho Santa Fe, La Jolla, and Del Mar.

When should a trustee call a real estate broker during the estate process?

Bring in a local broker before the estate appraisal is finalized. A broker with deep local market knowledge can run a current market analysis that gives the estate's appraiser a more accurate benchmark. Calling the broker after the appraisal is already filed eliminates the window to correct a low number without triggering a taxable gain.

Does hiring a second appraiser look suspicious to the IRS?

No. Getting a second appraisal is a recognized and accepted practice in estate administration. A well-documented second appraisal from a qualified specialist strengthens the estate's position. The goal is accuracy, and the IRS treats that as responsible estate management.

Do these same appraisal issues arise in Napa Valley or other second-home markets?

Yes. The same dynamics apply in any tightly defined luxury submarket where general appraisers may lack the local transaction history to value a property accurately. The principle is consistent: a broker with genuine market fluency, consulted before the trust property appraisal is finalized, can identify a significant discrepancy. I touched on related valuation and build-cost dynamics in a post comparing the value of ground-up construction to renovation.

What happens if the estate accepts a low appraisal and then sells for significantly more?

The difference between the filed estate value and the sale price becomes a taxable capital gain to the estate. Depending on the size of the spread and the applicable tax rate, that gap can cost beneficiaries tens of thousands of dollars in taxes. The problem is that once the number is filed, correcting it requires a formal challenge. That is slower, more expensive, and less certain than getting it right before filing.
