When a person passes away, their real estate is valued at its Fair Market Value on the date of their death. This value is not what they paid for it, nor is it the local tax assessment. It is the price a willing buyer would pay a willing seller on that specific day.
The primary conflict in this process comes from a federal tax rule: Internal Revenue Code (IRC) § 1014. This law creates a massive tax benefit for heirs called the “step-up in basis,” which resets the property’s cost basis to its value at death. This rule creates a direct financial conflict: a lower valuation may reduce estate tax, but it forces heirs to pay much higher capital gains taxes later.
This single issue is a major source of family tension. A study found that nearly 70% of families lose a portion of their inheritance due to fights over the estate. Understanding how valuation works is the key to preventing these costly disputes.

Decoding the Process: Who’s Involved and What Rules They Follow
To understand how property is valued, you first need to know the key players involved. You also need to know the fundamental concepts that govern their decisions. Think of it as a game with specific roles and a clear rulebook.
The Key Players on the Field
- The Executor (or Administrator): This is the person in charge of managing the estate. They have a fiduciary duty, which is the highest legal standard of care. This means they must act in the best interest of the estate and all its beneficiaries, not just themselves.
- The Beneficiaries (or Heirs): These are the people who will inherit the property. They have a legal right to be kept informed about the estate’s administration. This includes the right to see the property appraisal.
- The Probate Court: This is the legal body that oversees the estate settlement process. The court ensures the executor follows the law and the terms of the will. In some states, like California, the court appoints its own appraiser, called a “probate referee.”
- The Internal Revenue Service (IRS): The IRS is the federal agency that collects taxes. It sets the rules for what qualifies as a valid appraisal. It also defines the standards, like “Fair Market Value,” that everyone must follow.
- The Certified Appraiser: This is a state-licensed professional who provides an unbiased opinion of a property’s value. They are not real estate agents. They are neutral experts whose job is to determine the value based on facts and standardized methods.
The Rulebook: Core Concepts You Must Understand
These are the foundational rules that control every aspect of estate property valuation. Getting these right is critical.
What is Fair Market Value (FMV)?
The IRS has a very specific definition for the value that must be used. Fair Market Value (FMV) is “the price at which the property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or sell and both having reasonable knowledge of the relevant facts”.
This means the value is an objective estimate of what the property would sell for on the open market. It also considers the property’s “highest and best use.” For example, a small house on a large lot in a commercial zone might be valued for its potential as a site for a new store, not just as a house.
Why is the Date of Death So Important?
A property’s value is fixed on a specific day: the date the owner passed away. This is called a “date of death appraisal.” It is a retrospective valuation, meaning an appraiser looks back in time to determine what the market conditions and property value were on that historical date.
Federal law provides one major exception: the Alternate Valuation Date. Under IRC § 2032, the executor can choose to value the property six months after the date of death. This option is only allowed if it lowers both the total value of the estate and the amount of estate tax owed.
How the “Step-Up in Basis” Saves Heirs a Fortune
This is the single most important concept for beneficiaries to understand. A property’s “cost basis” is usually what was originally paid for it. When you sell a property, you pay capital gains tax on the profit, which is the sale price minus the cost basis.
However, IRC § 1014 changes the rule for inherited property. The property’s cost basis is “stepped up” to its Fair Market Value on the owner’s date of death. This erases all the taxable gain that accumulated during the deceased’s lifetime.
- Example: Your father bought a house in 1980 for $100,000 (his cost basis). When he passes away, the house is worth $700,000 (the Fair Market Value). Your new “stepped-up” cost basis is now $700,000.
- If you sell the house a year later for $725,000, you only pay capital gains tax on the $25,000 of profit. Without the step-up, you would have paid tax on $625,000 of profit.
This huge tax benefit depends entirely on a formal, defensible appraisal. Without it, the IRS could argue the basis is the original purchase price, or even zero.
A Special Note for Community Property States
In most states, only the deceased person’s share of a jointly owned property gets a step-up in basis. However, in community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin), the surviving spouse gets a “double step-up.” This means the entire value of the jointly owned property is stepped up, providing an even greater tax advantage.
Choosing Your Method: The Official Ways to Value Property
An executor must choose a method to determine the property’s Fair Market Value. The method you choose determines whether the IRS and the court will accept the value.
The Gold Standard: Why a Professional Appraisal is Non-Negotiable
This is the most accurate, reliable, and legally required method for tax and court purposes. A state-licensed appraiser provides an unbiased opinion of value. These professionals must follow the Uniform Standards of Professional Appraisal Practice (USPAP), which are the ethical and performance standards for their industry.
Appraisers use three main approaches:
- Sales Comparison Approach: This is the most common method for homes. The appraiser finds recent sales of similar nearby properties (“comps”) and makes dollar adjustments to account for differences.
- Cost Approach: This method is used for unique properties with few comps, like a custom-built home. It calculates value by adding the land value to the cost of building a replacement, then subtracting depreciation.
- Income Approach: This is for properties that generate income, like an apartment building. The value is based on the property’s ability to produce income.
The Quick Estimate: A Real Estate Agent’s Opinion
An executor can ask a real estate agent for a Comparative Market Analysis (CMA). The agent estimates a likely selling price based on their knowledge of the local market. This is often fast and free, but it is not an appraisal. The IRS and probate courts will not accept a CMA as official proof of value.
The Common Trap: Why Tax Assessed Value Can Cost You a Fortune
Many people use the value from the local property tax bill because it is easy and free. This is a major error. The IRS explicitly says not to use the tax assessed value. Tax assessments are for calculating property taxes, not market value, and are often outdated. Using a low tax assessment will destroy the step-up in basis benefit.
| Method | Best Use & Defensibility |
| Professional Appraisal | This is the only method accepted by the IRS and probate courts for official valuation. It provides the highest legal defensibility. |
| Real Estate Agent’s Opinion | Useful for informal planning or initial discussions between heirs. It has low legal defensibility and is not for tax filings. |
| Tax Assessed Value | This method is not accepted by the IRS or courts and should never be used for estate valuation. It offers no legal defensibility. |

Valuation in Action: Three Real-World Scenarios
Abstract rules become clear when you see them in action. Here are three common scenarios that executors and beneficiaries face.
Scenario 1: The Family Home Buyout
A mother passes away, leaving her home to her three children equally. One child, Sarah, wants to keep the home and buy out her two siblings, Tom and Lisa. The valuation is the key to a fair deal.
| Valuation Choice | Financial Outcome for Heirs |
| Low Appraisal ($750,000): Sarah hires an appraiser who values the home on the low end. | Sarah benefits greatly. She only needs to pay her siblings $500,000 total. Tom and Lisa each receive $16,667 less than they should have. |
| Accurate Appraisal ($800,000): The executor hires a neutral, certified appraiser. | The outcome is fair for everyone. Sarah pays $533,333 for the other two shares. Tom and Lisa each receive their fair share, preventing a family fight. |

Scenario 2: The Fixer-Upper Property
A father leaves his son a rental property that is in poor condition. It has a leaky roof and an outdated kitchen. The son plans to fix it up and sell it.
| Appraisal Approach | Tax Impact |
| “As-Is” Valuation: The appraiser values the property in its current, poor condition at $300,000. | This becomes the son’s stepped-up basis. He spends $50,000 on repairs and sells it for $450,000. His taxable gain is $100,000. |
| “Subject-To-Repairs” Valuation: The appraiser estimates what the property would be worth if repairs were done: $400,000. | This value is not used for the step-up basis, which must be the “as-is” value. However, it helps the son decide if the renovations are a good investment. |
Scenario 3: The Family Farm and a Powerful Tax Break
A family has owned a farm for generations. Its value for development is $3 million, but its value for farming is only $1 million. The $3 million value would trigger a huge estate tax, forcing the children to sell the farm.
| Valuation Strategy | Tax Consequence |
| Standard Fair Market Value: The farm is valued at $3 million. | This creates a massive estate tax liability that the family cannot afford. They are forced to sell the farm to developers. |
| IRC § 2032A Special Use Valuation: The executor elects to value the farm based on its agricultural use at $1 million. | This dramatically reduces the estate tax. The family can keep the farm, but they must continue farming it for 10 years or pay back the saved taxes. |

Red Flags and Pitfalls: 5 Costly Valuation Mistakes to Avoid
Getting the valuation wrong can have severe financial and legal consequences. Here are the most common mistakes executors and beneficiaries make.
- Using the County Tax Assessment. This is the #1 mistake. The tax assessor’s value is not Fair Market Value. Using this low number will result in a much higher capital gains tax bill when the property is sold.
- Intentionally Seeking a Low Value. Some people think a lower value is always better to avoid taxes. They save a small amount on probate fees but create a massive, unnecessary income tax liability for the heirs down the road.
- Hiring the Wrong Person. A real estate agent’s CMA is not an appraisal. You must hire a state-licensed or certified appraiser with experience in date-of-death valuations.
- Waiting Too Long. The appraisal needs to determine the value on the date of death. The longer you wait, the harder it is for an appraiser to find historical market data, and the more expensive the appraisal becomes.
- Failing to Document the Property’s Condition. The appraisal should reflect the property’s condition on the date of death. Take photos and make notes of any issues to support the valuation, especially if it’s lower than expected.
The High vs. Low Valuation Dilemma: Pros and Cons
The central conflict in estate valuation is choosing between a high or low appraisal. Each strategy has significant trade-offs for the estate and the beneficiaries. Understanding these is key to making an informed decision.
| Strategy | Pros & Cons |
| Seeking a Higher Valuation | Pro: Maximizes the “step-up in basis” for heirs, which dramatically reduces or eliminates their future capital gains tax when they sell the property. Con: Increases the Gross Estate value, which could trigger or increase an immediate estate tax liability for the estate to pay. |
| Seeking a Lower Valuation | Pro: Reduces the Gross Estate value, which can lower or eliminate an immediate estate tax bill. It can also lower probate court fees, which are sometimes based on the estate’s value. Con: Creates a lower “step-up in basis” for heirs, exposing them to a much larger capital gains tax bill when they eventually sell the property. |

The Executor’s Playbook: Your Step-by-Step Guide
As an executor, you have a fiduciary duty to get this right. Follow this checklist to manage the process correctly and protect yourself from liability.
- Step 1: Secure the Property and Gather Documents. Immediately secure the property by changing locks and checking insurance. Gather key documents: the death certificate, will, property deed, and recent tax statements.
- Step 2: Hire a Qualified Appraiser. You need a state-certified appraiser who specializes in retrospective “date-of-death” appraisals. Ask your estate attorney for a referral or consult professional organizations like the American Society of Appraisers (ASA).
- Step 3: Prepare for the Appraiser’s Visit. Provide the appraiser with copies of the documents you gathered. Create a list of any significant improvements made to the property. Ensure they have safe and complete access to the entire property.
- Step 4: Review the Final Appraisal Report. You must receive a formal, written report. A verbal estimate is not enough. The report must include the date-of-death value, a property description, the valuation method used, and the appraiser’s signature and license number.
- Step 5: File the Inventory with the Probate Court. The appraisal value is used on the official estate inventory form that you file with the court. In California, for example, this is Form DE-160 (Inventory and Appraisal).
- Step 6: Communicate the Results to All Beneficiaries. Transparency is your best defense against disputes. Proactively send a complete copy of the appraisal report to every beneficiary. This shows you are acting in good faith.
Facing the IRS: A Simple Guide to Form 706 for Real Estate
If the estate is large enough to require filing a federal estate tax return, you will use IRS Form 706. The real estate valuation is a critical part of this form.
- Schedule A – Real Estate: This is where you list every piece of real property the decedent owned.
- Line Item Details: For each property, you must provide a full description, the name of the appraiser, and the value on the date of death. You must attach a copy of the written appraisal to the return.
- Valuation Elections: On the main form, you must check “Yes” or “No” for two key elections:
- Line 1 (Alternate Valuation): You check “Yes” here if you are electing to value the assets six months after the date of death.
- Line 2 (Special Use Valuation): You check “Yes” here if you are electing to use the special valuation for a qualified farm under IRC § 2032A.
Protecting Your Inheritance: A Beneficiary’s Guide
As a beneficiary, you are not powerless. You have legal rights and can take steps to ensure the valuation is fair and accurate.
Do’s and Don’ts for Beneficiaries
| Do’s | Don’ts |
| Do formally request a copy of the estate inventory and the full appraisal report. You have a legal right to this information. | Don’t immediately assume the executor is acting in bad faith. Clear communication can resolve most issues. |
| Do review the appraisal carefully. Look for errors, outdated comps, or anything that seems incorrect. | Don’t rely on Zillow or online estimates. They are not appraisals and have no legal standing. |
| Do hire your own certified appraiser for a second opinion if you have a valid reason to believe the valuation is wrong. | Don’t wait to voice your concerns. Deadlines in probate are strict. Raise issues early and in writing. |
| Do communicate with the executor respectfully and in writing. Documenting your questions creates a clear record. | Don’t start a family war over minor disagreements. Consider the emotional and financial cost of a legal battle. |
| Do consult with your own estate attorney to understand your rights and options. | Don’t make threats or accusations. Approach the issue with facts, such as a competing appraisal report. |

How to Formally Challenge an Appraisal
If you believe a valuation is wrong, there is a formal process to follow.
- Grounds for a Challenge: You must have a valid reason. Common grounds include a conflict of interest, the use of flawed data, or the omission of key features.
- Start with the Executor: Present your concerns to the executor in writing, along with your evidence, like a second appraisal. Often, the issue can be resolved at this stage.
- Mediation: If direct talks fail, suggest mediation. A neutral third-party mediator helps all parties negotiate a solution. This is much cheaper and faster than going to court.
- Petition the Probate Court: As a last resort, you can file a formal objection with the probate court. You will present your evidence, and a judge will make a final ruling on the property’s value.
Frequently Asked Questions (FAQs)
Q: Do I need an appraisal if the estate is small and won’t owe any estate tax? A: Yes, it is highly recommended. The appraisal officially documents the “step-up in basis.” Without it, you could pay thousands in unnecessary capital gains taxes when you sell the property.
Q: How much does an estate appraisal cost? A: No, the cost is a flat fee, typically between $400 and $1,500 for a standard home. Appraisers who charge a percentage of the property’s value are violating ethical standards.
Q: Can I just use the Zillow or Redfin estimate for the value? A: No. Online estimates are not appraisals and are not legally defensible. The IRS and probate courts require an appraisal from a licensed professional.
Q: How long does the appraisal process take? A: No, the on-site inspection is quick, but the research and report writing take time. The entire process typically takes one to two weeks for a standard property.
Q: What if the inherited property is in a different state? A: Yes, you must hire an appraiser who is licensed and certified in the state where the property is located. Real estate laws and markets are state-specific.
Q: Can the executor use the sale price as the value if the house sells quickly? A: Yes, in many cases. If the property is sold in a fair transaction within six months to a year of death, the IRS will generally accept the gross sale price as its Fair Market Value.
