When a property owner dies in Arizona and their real estate passes through probate, one of the first practical tasks for the personal representative (executor) is establishing the property's value. That value determines the estate's assets for court filing, creditor claims, tax liability, and equitable distribution to heirs.
This guide explains when a licensed appraisal is required, what the Maricopa County Superior Court expects, and how to get one done quickly without delaying the estate administration timeline.
When Is a Licensed Appraisal Required in Arizona Probate?
Under Arizona Revised Statutes Title 14 (Probate Code), the personal representative is required to prepare an inventory of estate assets, including real property, within 90 days of appointment. While Arizona law doesn't always mandate a formal licensed appraisal for the probate inventory itself, several situations make one effectively required:
- The estate includes federal estate tax liability. If the gross estate exceeds the federal exemption ($13.61M in 2024, $13.99M in 2025), IRS Form 706 requires a qualified appraisal attached to the return. The IRS rejects broker price opinions and Zillow estimates.
- A beneficiary disputes the value. When heirs disagree about what a property is worth, a licensed appraisal is the only defensible number that can resolve — or withstand — that dispute.
- The property will be sold during probate. The Maricopa County Superior Court may require a licensed appraisal to confirm the sale price is reasonable before approving the transaction.
- A surviving spouse claims an elective share. Property values must be established on the date of death to calculate the elective share accurately.
- A conservator or guardian is managing the estate. Court-supervised conservatorships regularly require licensed appraisals to account for real property assets.
Even when not strictly required, most experienced estate attorneys order one anyway — a defensible, licensed value eliminates the single most common source of heir disputes.
The Date-of-Death Distinction
Probate appraisals are almost always retrospective — meaning the appraiser is valuing the property as of a past date (the date of death), not today's market. This is sometimes called a "date-of-death appraisal" or "retrospective appraisal."
The distinction matters enormously in a market like the Phoenix Metro, where values have moved significantly over the past two to three years. A property the deceased owned that's worth $450,000 today may have been worth $390,000 eighteen months ago. The estate tax liability — and the heirs' stepped-up basis — is based on the date-of-death value, not today's value.
A licensed appraiser can perform a retrospective appraisal for any date in the past by using comparable sales that were available as of that date and applying market conditions that existed at that time. This is standard practice — not unusual — and the report carries the same USPAP compliance as a current-date appraisal.
What the Maricopa County Probate Court Expects
For estates administered through the Maricopa County Superior Court Probate Division (201 W. Jefferson, Phoenix), the court does not prescribe a specific appraisal format — but it does expect values to be defensible and professionally supported. In practice, this means:
- A report prepared by a state-licensed or certified appraiser (not an agent, broker, or online estimate)
- A clear statement of the effective date (the date-of-death or other relevant date)
- Comparable sales analysis supporting the value conclusion
- A USPAP-compliant certification signed by the appraiser
Desktop appraisals (which don't require an interior inspection) are generally acceptable for probate purposes in Arizona, particularly for properties where the interior condition is documented or known. For properties in significantly distressed condition, a full interior inspection may be warranted to document condition adjustments.
The Step-Up in Basis: Why It Matters to Heirs
Beyond probate administration, there's a compelling financial reason heirs care deeply about the date-of-death value: the step-up in basis.
When an heir inherits real property, their cost basis for future capital gains tax purposes is "stepped up" to the fair market value on the date of death — not what the deceased originally paid for it. If a parent paid $120,000 for a home in 1992 and it's worth $510,000 when they pass, the heir's basis is $510,000. If they sell immediately, they owe no capital gains tax.
This means a high-quality date-of-death appraisal isn't just a legal formality — it's direct financial protection for the heirs. An unsupported or under-valued date-of-death figure can cost a family tens of thousands of dollars in unnecessary capital gains taxes years later.
Timeline: How Quickly Can You Get a Probate Appraisal?
Estate timelines are rarely flexible. Court hearings, IRS filing deadlines, creditor notice periods, and distribution schedules don't wait for appraisers. Traditional full appraisals with interior inspections can take 2–3 weeks from order to delivery.
A licensed desktop appraisal for probate purposes — where the property is residential and public records + MLS data are sufficient — can typically be delivered within 24 hours. For attorneys managing tight estate timelines, that turnaround is often the difference between hitting a filing window and missing it.
What to Provide When Ordering a Probate Appraisal
To get the most accurate report in the fastest time, provide:
- The date of death — exact date for the retrospective effective date
- Property address and APN if available
- Intended use — estate tax return, court inventory, heir distribution, or property sale
- Known property condition at time of death — any deferred maintenance, remodels, or damage worth noting
- Any unusual features — pool, casita, large lot, commercial-adjacent — that might affect comparable selection
What It Costs
A licensed probate appraisal from Next Day Desktop Valuations is $175 flat — that covers a full USPAP-compliant report with retrospective effective date analysis, comparable sales, market conditions, and a signed certification. Rush delivery (same business day) is available for an additional $75.
For context: a single heir dispute over an unsupported property value can cost $5,000–$25,000 in attorney fees to resolve. A $175 report that establishes a defensible number from day one is cheap insurance.
