Selling an Inherited Home on Long Island? Why You May Need a Date of Death Appraisal

Inheriting a home can create a complex mix of legal, financial, and practical decisions. For many families on Long Island, one of the biggest questions is simple: What do we do with the house?

Some heirs choose to keep the property. Others transfer ownership among family members. But in many estates, the decision is to sell the inherited home.

Before listing the property, executors and heirs should understand a key valuation issue. The home's selling price today is not necessarily the value that matters for estate and tax purposes.

In many cases, the relevant figure is the property's fair market value as of the previous owner's date of death.

That is where a professional date-of-death appraisal can be extremely important.

Selling Price and Date of Death Value Are Two Different Numbers

Imagine a parent passed away in March 2023, and the family is preparing to sell the Long Island home in 2026.

The property might be worth $850,000 today, but it may have been worth about $700,000 on the date of death.

Those are two completely different valuations, each serving a different purpose.

A real estate agent may help determine an appropriate current listing price, whereas a date-of-death appraisal looks backward to determine what the property was worth on a specific historical date.

This type of valuation is called a retrospective appraisal.

For a more detailed explanation of how historical valuations are conducted, see:

Why the Date of Death Value Can Matter When You Sell

When real estate is inherited, the property's tax basis may be adjusted based upon its fair market value at the owner's death.

This is commonly called the step-up in basis.

For example, suppose a parent purchased a Long Island home decades ago for $175,000. At the time of death, the property was worth $725,000. Several years later, the heirs sell it for $800,000.

The original $175,000 purchase price may not be the starting point used when determining the taxable gain on the inherited property. Instead, the property's value at the date of death may become important when establishing the new basis.

The difference can be substantial.

Because every estate and tax situation is different, heirs should discuss the applicable tax treatment with an attorney or CPA. The appraiser's role is to provide a credible and independently supported opinion of the property's fair market value as of the required date.

Do Not Wait Until After the House Is Sold

One of the most common situations I encounter involves heirs who have already sold an inherited property and later learn from their accountant or attorney that they need a date-of-death appraisal.

Fortunately, a retrospective appraisal can often still be conducted.

However, obtaining the appraisal before the property is renovated, emptied, altered, or sold can make it easier to document its condition at the time of death.

Consider what can happen between the date of death and the eventual sale:

The house may be cleaned out.
Kitchens or bathrooms may be renovated.
Roofing, windows, or mechanical systems may be replaced.
Interior painting and flooring may be completed.
Landscaping may be improved.
Deferred maintenance may be corrected.
The home may be professionally staged.
The property may eventually be sold to a new owner who makes additional improvements.

The appraisal must reflect the property as it existed on the Date of Death, not how it looks after those changes.

The more information available about the home's historical condition, the better the appraiser can reconstruct the property as of the retrospective effective date.

What If the Inherited House Has Already Been Renovated?

This is very common.

An executor may decide that spending $50,000 or $100,000 to renovate an inherited home will make it easier to sell. The renovations could substantially increase the property's appeal and selling price.

However, those improvements generally should not simply be treated as if they existed on the Date of Death.

For example, if a dated kitchen existed at the time of the owner's passing but a new kitchen was installed two years later, the retrospective appraisal should reflect the earlier kitchen.

An appraiser may review available information, including prior MLS photographs, family photographs, inspection reports, permits, previous appraisals, contractor invoices, and information provided by parties familiar with the property.

This is one reason why historical property documentation can be extremely valuable.

The Sale Price Does Not Automatically Establish the Date of Death Value

Executors sometimes assume that if the house was eventually sold for $900,000, its date-of-death value must also have been approximately $900,000.

That is not necessarily true.

Market conditions on Long Island can change significantly over a relatively short period.

Between the date of death and the eventual sale, there may have been changes to:

Mortgage interest rates
Housing inventory
Buyer demand
Median home prices
Property condition
Renovations
Seasonal market conditions
Neighborhood demand

A sale that occurs months or years after the required valuation date must therefore be analyzed carefully rather than automatically treated as the historical market value.

The objective of a retrospective appraisal is to recreate the market as it existed on the effective date.

Should You Get the Appraisal Before Listing the Inherited Home?

If you know that a Date of Death value will be needed for the estate, there can be advantages to completing the appraisal while the property remains under the family's control.

The appraiser can document the home's size, layout, condition, amenities, and overall characteristics before any changes are made.

This can be especially helpful for older Long Island homes where there may be:

Deferred maintenance
Finished basements
Converted garages
Additions
Accessory apartments
Older kitchens and bathrooms
Unpermitted improvements
Significant renovation needs
Unique waterfront or location influences

The appraisal can then establish retrospective value using market data relevant to the Date of Death.

If the family also wants help understanding the property's current value before selling, that is a separate valuation question. In some situations, both a Date of Death value and a current market value may be useful.

An Estate Appraisal Is Different From a Realtor's CMA

A real estate agent's Comparative Market Analysis can be extremely useful when deciding how best to market a property for sale.

A professional estate appraisal serves a distinct purpose.

An appraisal is an independent opinion of value developed under professional appraisal standards and supported by market evidence.

Estate appraisals may be used by executors, administrators, attorneys, accountants, and beneficiaries to document property value for estate administration, tax reporting, or other legal purposes.

DMA Appraisers provides Estate Appraisal Services throughout Nassau County, Suffolk County, and Long Island, including date-of-death and retrospective valuations.

What If Several Heirs Inherit the Property?

An independent appraisal can also help when multiple beneficiaries are involved.

One heir may want to sell the property, while another wants to keep it. In other cases, one family member may want to purchase the other heirs' interests.

Having an independent opinion of market value can provide a neutral starting point for those discussions.

The appropriate valuation date depends on the appraisal's purpose. A Date of Death appraisal establishes historical value, whereas a current appraisal reflects today's market.

Sometimes an estate may need both.

What If the Date of Death Was Several Years Ago?

A Date of Death appraisal does not necessarily need to be ordered immediately after someone passes away.

Retrospective appraisals can often be completed years afterward.

The appraiser researches sales, listings, and market conditions around the historical effective date rather than relying on the current market.

For example, an appraisal completed in 2026 might determine the value of a Massapequa, Garden City, Huntington, Port Washington, or Smithtown home in 2020, 2018, or another prior year.

The availability and quality of historical information become increasingly important as the effective date moves further into the past.

What If the Home Has Already Been Sold and You No Longer Have Access?

If an inherited home has already been sold and the estate no longer has access to the property, a desktop retrospective appraisal may still be possible. In these situations, the appraiser may rely on public records, prior MLS listings and photographs, tax records, deeds, permits, prior appraisal information, historical aerial imagery, and other reliable documentation to reconstruct the property's characteristics and condition as of the Date of Death.

A desktop appraisal does not include a current interior inspection, so the amount and quality of historical information matter even more. This can be a practical option for executors, heirs, attorneys, and accountants who discover after the sale that they need a Date of Death value for estate administration or tax purposes.

Before Selling an Inherited Long Island Home, Ask These Questions

If you are an executor, administrator, or beneficiary preparing to sell inherited real estate, consider discussing the following with your attorney or accountant:

Do we need to establish the home's fair market value as of the Date of Death?
Will we need the valuation to establish the property's tax basis?
Should we complete the appraisal before renovations?
Do we also need a current appraisal before listing or distributing the property?
Do multiple beneficiaries benefit from an independent valuation?

Obtaining answers early can prevent families from trying to reconstruct the property's condition and historical market value years after the sale.

Frequently Asked Questions

Do I need a Date of Death appraisal before selling an inherited home?

Not every estate requires the same documentation. However, you may need a Date of Death appraisal to establish the property's historical fair market value for estate administration, tax basis, capital gains calculations, or other legal and financial purposes. Your CPA or estate attorney can determine whether you need one.

Can a Realtor determine the Date of Death value?

A Realtor can provide useful market information and a CMA, especially when preparing a home for sale. When a formal, independently supported retrospective valuation is required for estate, legal, or tax purposes, a professional real estate appraisal may be more appropriate.

Can the appraisal be completed after the inherited home is sold?

Yes. A retrospective appraisal can often be completed after a property has already been sold. The appraiser researches historical market data and available information on the property's condition as of the Date of Death.

What happens if the house was renovated after the owner's death?

The appraisal should reflect the property as it existed on the Date of Death. Identify any improvements completed afterward so the retrospective valuation does not incorrectly attribute those renovations to the earlier property condition.

Can an appraisal provide both the Date of Death value and today's value?

Yes. Depending on the intended use, an appraiser may be engaged to provide separate opinions of value for the historical Date of Death and the property's current market value.

How far back can a Date of Death appraisal extend?

Retrospective appraisals can often be completed many years after the effective date, when adequate historical property and market information is available. Each assignment depends on the property, the effective date, and the available data.
