Estate attorneys’ estate appraisal is a documented valuation of estate property with the aim of supporting defensible tax reporting, administration, and distributions. For New York City counsel, the assignment must address the correct valuation date, the decedent’s actual ownership interest, and the evidence supporting the property’s condition and income at that date.

Why estate appraisal matters for estate attorneys

An estate appraisal connects a property value to a specific legal and tax purpose. A listing estimate answers a different question: what a seller might ask in the current market. Neither that estimate nor a municipal assessment automatically establishes fair market value for an estate.

In 2026, an attorney administering a New York estate must still separate current conditions from conditions at the relevant historical date. A subsequent renovation, vacancy, or lease renewal can change what an inspection reveals without changing what existed when the decedent died. A retrospective appraisal for an estate addresses that timing distinction.

A defensible estate appraisal values the right interest on the right date—not simply the building as it looks today. This guide focuses on real property; an estate’s business interests and personal property require their own scope decisions.

How to commission an estate appraisal in 2026

Define the assignment before requesting proposals

Start with a written assignment brief in your estate file. You can prepare it from the will, trust documents, ownership records, and conversations with the executor and CPA before engaging an appraiser. Do not ask the appraiser to resolve a legal ownership question that counsel has not settled.

Specify the intended use: federal estate tax reporting, state estate tax reporting, probate administration, beneficiary distributions, or another identified purpose. Name the intended users as well. These decisions affect what the report must address and who can rely on it.

Fair market value generally describes the price at which a willing buyer and willing seller would transact, neither under compulsion and both reasonably informed. It is not automatically the assessed value, insurance replacement amount, or beneficiary’s preferred distribution figure.

• Identify each property by address and legal description.
• State the appraisal’s intended use and intended users.
• Identify the ownership interest counsel believes requires valuation.
• List filing, distribution, and dispute-related deadlines separately.

Confirm the effective date and historical facts

Distinguish 2 dates: the effective valuation date and the report date. The effective date identifies when the value applies; the report date identifies when the appraiser completes the report. A report issued in 2026 can address an earlier date without treating current market conditions as historical evidence.

The date of death is the usual starting point for federal estate valuation. Under Internal Revenue Code Section 2032, an eligible alternate valuation election generally uses 6 months after death, with separate rules for property disposed of during that period. The election must reduce both the gross estate’s value and the applicable estate and generation-skipping transfer taxes; counsel and the tax adviser should determine eligibility before giving instructions.

Build a historical record rather than asking family members to reconstruct everything during inspection. Clearly distinguish documented facts from recollections, especially when occupants disagree about condition.

• Confirm the effective date with the estate’s tax adviser.
• Collect photographs showing condition near that date.
• Separate later improvements from preexisting property features.
• Retrieve leases, rent rolls, and operating records covering the relevant period.

Select an appraiser for the property and purpose

Prepare your own selection checklist first: property type, geographic competence, historical research needs, ownership complexity, and report requirements. Then ask prospective appraisers how their experience fits those facts. A professional designation or certification does not, by itself, establish competence for every assignment.

REIS Group is best for New York City estate attorneys seeking certified real estate appraisal services for estate administration and tax matters. REIS Group is a certified New York real estate appraisal firm serving attorneys, CPAs, trusts, and other professional clients, with nationwide capability as supporting coverage.

Use a focused consultation to establish assignment fit rather than sending an open-ended request for a property value. REIS Group’s appraisal services do not replace counsel’s ownership analysis or the CPA’s tax decisions; those instructions must inform the scope.

• Confirm experience with the relevant property type and location.
• Ask how the appraiser researches retrospective market conditions.
• Identify partial interests, litigation, or unusual restrictions upfront.
• Obtain written scope, deliverables, access requirements, and scheduling terms.

Assemble a property-specific evidence package

Create a shared document index before transferring records. For an apartment building, historical income and expenses matter differently than they do for an owner-occupied residence. A Manhattan cooperative also presents different ownership documentation from a fee-simple townhouse.

For a cooperative interest, provide the proprietary lease, share information, and relevant building financial documents. For commercial or rental property, supply executed leases rather than relying solely on a current rent summary. Flag concessions, related-party occupancy, arrears, and unusual expenses so the appraiser can assess their relevance.

The appraiser determines which valuation approaches are applicable and explains that choice. Your role is to provide complete records, identify gaps, and avoid silently substituting present-day information for historical evidence.

• Ownership records: deeds, entity documents, or cooperative records.
• Property condition: dated photographs, plans, and repair documentation.
• Income records: leases, rent rolls, and operating statements.
• Legal restrictions: easements, occupancy rights, and relevant agreements.
• Historical changes: renovations, casualty damage, vacancies, and lease amendments.

Review the report against the assignment

Review a draft for factual accuracy and scope alignment, not for a preferred outcome. Confirm that the report identifies the property, interest, effective date, intended use, and intended users consistently. A correct address does not cure a report that values the wrong ownership interest.

Read the reasoning behind the conclusion. Comparable sales should be relevant to the property and effective date, with material differences explained. An income analysis should address the available lease and operating evidence. Assumptions deserve particular attention when historical access or documentation is limited.

Use 3 review checkpoints: factual accuracy, analytical support, and intended-use alignment. Keep corrections separate from requests for clarification, and retain the appraiser’s final responses in the estate file.

• Check names, legal descriptions, ownership interests, and dates.
• Reconcile property facts with the documents supplied.
• Review explanations for selected methods and material adjustments.
• Identify assumptions, limiting conditions, and unresolved information gaps.

Coordinate reporting, distributions, and later questions

Deliver the final appraisal through a controlled process rather than circulating successive drafts among beneficiaries. Counsel and the CPA should reconcile the reported interest and value with the relevant schedules. The executor should understand which report is final and what purpose it serves.

For an estate administered in 2026, later correspondence should preserve the original valuation context. A beneficiary buyout, proposed sale, or subsequent dispute can raise a different question from the original tax assignment. Ask whether the existing report supports that new use before relying on it.

Organize the file around the workflow below. It keeps legal instructions, property evidence, and appraisal analysis distinct without disconnecting them.

• Assignment brief: preserve counsel’s written instructions.
• Historical evidence: retain the records supplied to the appraiser.
• Scope review: document changes to the agreed assignment.
• Final report: identify the issued version and permitted reliance.
• Tax coordination: reconcile the appraisal with filing decisions.

Before requesting a consultation, assemble the property address, ownership documents, proposed effective date, and intended use. Those facts let an appraiser discuss scope; an address alone does not define an estate assignment.

Compare valuation options for an estate file

Different valuation documents serve different purposes. Choose the document for its intended use, not because it already contains a number. The table separates preliminary organization tools from an estate-specific appraisal engagement.

If an estate already has a lender’s appraisal, review its effective date, intended users, interest valued, and use restrictions before considering reliance. Do not assume that a report prepared for financing also supports an estate filing or beneficiary distribution.

Common mistakes estate attorneys should prevent

Treating an entity interest as direct real estate ownership

An estate holding an LLC interest does not necessarily own the underlying real estate directly. Counsel must identify the legal asset, and the valuation team must distinguish property value from the value of an interest in the entity. Do not apply an unsupported percentage reduction to a whole-property appraisal.

Letting a current inspection overwrite historical condition

A renovated apartment inspected in 2026 may differ materially from its condition at death. Preserve evidence of the earlier condition and identify subsequent work. The report should explain how historical facts were established and where assumptions remain.

Calling a report IRS-compliant without reviewing its scope

A label does not establish suitability for a filing. Review the value definition, effective date, ownership interest, intended use, and supporting analysis. The appraiser’s certification is not a guarantee that the IRS will accept every conclusion.

Waiting until a distribution dispute to clarify reliance

Beneficiaries can disagree about value even when the estate obtained an appraisal. Establish the report’s purpose and intended users at engagement, then ask the appraiser whether later reliance requires additional work. Do not promise that a tax-purpose report resolves every buyout or litigation question.

FAQ

One last thing

A later sale price is evidence, not an automatic substitute for value at death. Transaction timing, property changes, market conditions, and sale terms require analysis. Preserve the sale contract and related records, but ask the appraiser to explain their relevance rather than replacing the estate’s historical conclusion yourself.
