Westchester Estate & Date-of-Death Appraisals: Guide for Executors & Attorneys

When a Westchester estate opens — for Surrogate’s Court inventory, Form 706, stepped-up basis, or heir buyouts — counsel and executors need a number that survives tax, court, and beneficiary scrutiny. A Zillow screenshot, a listing agent’s CMA, or a leftover refinance appraisal rarely does. What estate counsel typically order is a private, USPAP-compliant appraisal scoped for estate use: an independent market-value opinion with a stated effective date (often the date of death), intended users, and transparent comparable selection grounded in closed sales, inventory, DOM, and sale-to-list evidence.

This briefing is for attorneys, executors, and trustees handling Westchester probate and estate-tax valuations. It covers why a certified private appraisal is the right tool, date-of-death versus current value, retrospective evidence, Form 706 and stepped-up basis use cases, engagement-letter terms that prevent later fights, and how town-level comps in Westchester actually work.

A Westchester estate appraisal answers a practical question: what would a willing buyer pay a willing seller for this residential interest under market conditions as of the agreed effective date — usually the date of death — so counsel can inventory the estate, report fair market value, and set basis with a defensible paper trail.

Why Estate Counsel Order a Private USPAP Appraisal

Probate and estate-tax disputes stall when the file rests on the wrong product. Westchester counsel who want a defensible FMV baseline usually reject shortcuts for the same reasons they do in divorce and gift work:

• CMAs bracket a listing price for marketing. They are not independent appraisal opinions with USPAP certifications and intended-user statements counsel can attach to a Form 706 schedule or Surrogate’s inventory.
• AVMs do not inspect condition, do not reconstruct market conditions as of a past date of death, and do not document extraordinary assumptions common when the house has sat vacant or been staged for sale after death.
• Lender appraisals are written for underwriting under GSE or investor guidelines, often with a lending effective date and intended users limited to the lender/client — not the executor, counsel, or IRS.

Reusing a refinance appraisal for date-of-death value is a frequent source of dispute when the IRS, opposing beneficiaries, or Surrogate’s Court notice the wrong intended use, missing retrospective analysis, or a date that does not match the date of death.

Date of Death vs Current Market Value

Most Westchester estate engagements require value as of the date of death, not “today’s” market. That is a retrospective assignment: the appraiser reconstructs market conditions, inventory, and closed sales as of that date, even though the inspection often occurs months later. Current value is a different opinion — useful for a near-term sale, heir buyout, or refinance — but it is not a substitute for Form 706 FMV or stepped-up basis when the tax effective date is the date of death.

Counsel should decide early whether the engagement calls for:

1. Date-of-death value — retrospective USPAP opinion for inventory, Form 706, and stepped-up basis.
2. Current market value — for listing strategy, heir buyout, or near-term disposition.
3. Alternate valuation date (AVD) — when the estate elects AVD under IRC §2032 and needs value six months after death (or disposition date if earlier). Deep dive: alternate valuation date appraisals.
4. Dual dates — when counsel need both date-of-death and current (or AVD) figures — two opinions, clearly labeled, with matched scopes.

Mixing a current CMA with a date-of-death tax schedule is a common dispute trigger. Align the effective date in the engagement letter first; the Form 706 and basis worksheets follow.

Form 706, Stepped-Up Basis & Probate Inventory

Westchester estates use private appraisals for several overlapping legal and tax jobs. The report should name the intended use so the opinion plugs into the right schedule:

• Form 706 / estate tax — fair market value of residential real property as of the date of death (or AVD). See also qualified appraiser requirements for IRS estate reporting.
• Stepped-up basis — heirs and fiduciaries often need a defensible date-of-death FMV to reset basis for a later sale; capital-gains planning then ties to that figure. Service page: capital gains appraisal; Insights: step-up in basis for high-net-worth estates.
• Surrogate’s Court / probate inventory — estate inventory and accounting often require an independent value for the residential asset, especially when heirs disagree or the property will be distributed in kind.
• Heir buyouts and partition — when one beneficiary keeps the house, counsel convert appraised FMV into equity after liens — similar buyout math to divorce, but with estate intended use.

Retrospective Evidence in Westchester Markets

A retrospective Westchester appraisal is not a guess backward from today’s asking prices. The appraiser builds a market snapshot as of the effective date using:

• Closed sales that would have been available to a buyer as of the date of death (with attention to contract vs. closing timing)
• Active and pending inventory levels as of that date
• Days on market and sale-to-list ratios in the competitive set
• Volume trends — not lifestyle or demographic claims
• Subject condition as of the effective date, with extraordinary assumptions stated when the house has since been renovated, cleared, or damaged

Westchester comps are town- and segment-specific. A Scarsdale colonial does not price like a Peekskill ranch; a Bronxville co-op is not interchangeable with a Rye fee-simple home; Larchmont, Mamaroneck, New Rochelle, White Plains, Chappaqua, Bedford, and the Rivertowns each have their own competitive sets. Countywide medians are context only. Market-strength language in the report should stay on measurable indicators — prices, inventory, DOM, sale-to-list, and volume — never schools, crime, “quiet/safe neighborhood,” walkability, or demographic characterizations.

Engagement Terms Attorneys & Executors Care About

Clear scoping prevents most estate-appraisal fights before they start. At minimum, the engagement letter (or appraisal order) for a Westchester estate matter should specify:

1. Effective date — date of death, alternate valuation date, current date, or dual dates.
2. Property identification — address, municipality/town, tax map / block-lot, and ownership type (fee-simple, co-op shares, condo).
3. Intended use — Form 706 / estate tax, stepped-up basis, Surrogate’s inventory, heir buyout, or litigation support.
4. Intended users — named counsel, executor/trustee, and whether the report may be shared with the IRS, Surrogate’s Court, co-counsel, or beneficiaries.
5. Scope of inspection — interior/exterior, or exterior-only with stated limitations when access or contents delay entry.
6. Hypothetical conditions / extraordinary assumptions — e.g., condition as of date of death; post-death renovations ignored or analyzed; vacant vs. occupied; personal property excluded.
7. Fee, retainer, and payment responsibility — estate, counsel escrow, or named fiduciary; turnaround when Surrogate or tax deadlines are tight.

Counsel who treat the engagement letter as a checklist — not boilerplate — get reports that plug directly into Form 706 schedules and basis worksheets.

Final Thoughts

Westchester estate valuations succeed when counsel and executors start from a shared, defensible market value as of the right effective date — not from competing CMAs or AVMs. A private USPAP appraisal names the date of death (or AVD/current), intended users, and intended use; selects comps inside the right Westchester competitive set using price, inventory, DOM, and sale-to-list evidence; documents retrospective market conditions; and gives fiduciaries a number they can file, report, and defend. Align the question in the engagement letter first; the inventory, Form 706, and basis math follow.
