Selling an Inherited NYC Property

The stepped-up basis rule under IRS Section 1014 is one of the most valuable tax benefits available to heirs of NYC real estate, and it is one of the most frequently misunderstood. A co-op purchased in Washington Heights for $60,000 in 1985 that is worth $650,000 today passes to heirs with a basis of $650,000, not $60,000. In my experience working with estate sales across Upper Manhattan and all five boroughs, heirs who understand this rule before listing often save six-figure tax liabilities simply by timing the sale correctly and documenting the date-of-death appraisal properly. This guide covers everything heirs and executors need to know about selling an inherited NYC property.

Nothing in this guide constitutes legal or tax advice. Estate sales involve overlapping decisions in estate law, tax law, and real estate contract law. Every decision should involve your estate attorney and CPA working alongside the listing agent.

Understanding Stepped-Up Basis (IRS Section 1014)

When someone inherits property, they receive a new cost basis equal to the fair market value of the property on the decedent's date of death. This is called a "stepped-up" basis because the property's value has typically increased since the original purchase, and the basis steps up to that higher current value. The practical effect: decades of appreciation that would have been taxable as capital gain if the original owner had sold during their lifetime are permanently excluded from taxation at death.

How the Stepped-Up Basis Is Calculated

The stepped-up basis must be supported by a certified appraisal conducted as of the date of death. This appraisal is also required for estate tax purposes and for documenting the estate's value in the probate proceeding. Your estate attorney will arrange or request this appraisal as part of the standard estate administration process. Consult your CPA on the alternate valuation date election (6 months after death), which may result in a higher or lower basis depending on market movement.

NY Probate: The Process and Timeline

Probate in New York is administered by the Surrogate's Court in the county where the decedent resided. The process begins when the Executor named in the will files a petition for probate, presents the original will, and requests issuance of Letters Testamentary, which are the legal documents authorizing the Executor to act on behalf of the estate.

Standard Probate Timeline in NYC

• Month 1: File petition with Surrogate's Court, submit original will, notify all interested parties (distributees, creditors)
• Months 2 to 3: Surrogate's Court processes paperwork, issues citation to interested parties who must be served notice
• Months 3 to 5: Return date on citation; if uncontested, court moves toward issuing Letters Testamentary
• Months 4 to 8: Letters Testamentary typically issued for uncontested estates; contested estates can take 18 months or more
• After Letters: Executor has authority to list, contract, and close the sale of estate real property

The listing can be placed and offers received before Letters are issued, using a contract contingency that conditions closing on the issuance of Letters Testamentary. This approach can reduce the total time from death to closing by 2 to 3 months in some cases. Your estate attorney determines whether a contingency-based listing is appropriate for your specific estate.

Executor Responsibilities in a Property Sale

The Executor of the estate is the legal representative with authority to sell estate real property. The Executor's duties in a property sale include:

• Obtaining a date-of-death appraisal to establish value for estate tax and capital gains purposes
• Maintaining the property (insurance, utilities, maintenance fees, real estate taxes) until sale closes
• Obtaining Letters Testamentary before executing the contract of sale or appearing at closing on behalf of the estate
• Signing the contract of sale and transfer documents in the capacity of "Executor of the Estate of [Decedent Name]"
• Distributing net proceeds per the will's terms and the estate tax requirements after closing

The Executor is a fiduciary and must act in the best interests of all beneficiaries, not just their own interests. If an Executor is also a beneficiary, and acts in a way that advantages themselves over other beneficiaries, the other beneficiaries can petition the Surrogate's Court for relief. Your estate attorney advises the Executor on fiduciary duties throughout the transaction.

Selling During Probate vs. After Letters Testamentary

The decision to list before or after Letters Testamentary depends on market conditions, the estate's financial needs, and the complexity of the probate proceeding.

Multiple Heirs and Beneficiary Disagreements

When two or more beneficiaries inherit an interest in the same NYC property and disagree about whether to sell, the legal resolution depends on how the property is held:

• Property held in trust: The trustee has authority to sell per the trust's terms. Beneficiaries who disagree with the trustee's decision must petition the Surrogate's Court.
• Property held as tenants in common: Any co-owner can file a partition action under RPAPL Article 9 to compel a sale or a buyout. Partition sales typically produce lower prices than cooperative sales because of the compressed timeline and the involvement of a court-appointed referee.
• Property distributed to a single beneficiary: That beneficiary has sole authority to sell. Other beneficiaries who believe the distribution was improper must contest in Surrogate's Court.
• Intestacy (no will): All distributees (heirs at law) must consent to a sale, or the Administrator must obtain court authorization.

When multiple heirs are involved and all agree to sell, I request written authorization from all parties, typically in a form prepared by the estate attorney, before accepting the listing. This prevents conflicting instructions mid-transaction.

HDFC Co-op Inheritance Rules

HDFC (Housing Development Fund Corporation) co-operatives in NYC operate under income-restricted rules that affect not only sales to buyers but also transfers to heirs. HDFC buildings were created to provide affordable homeownership to income-qualifying residents. When an HDFC shareholder dies, the rules governing who can inherit the shares and proprietary lease vary by building and are governed by the individual HDFC's by-laws and proprietary lease.

Common HDFC inheritance provisions include:

• Qualified successor occupants: Many HDFC by-laws allow shares to transfer to a spouse, domestic partner, or other qualifying family member who has lived in the unit as a primary residence and meets the income qualification, typically set at 80% or 120% of NYC Area Median Income (AMI)
• Income qualification for heirs: If the heir does not meet the HDFC's income threshold, they typically cannot retain the unit and must sell within a defined period (often 6 to 12 months)
• Sale price caps: Some HDFC buildings impose resale price restrictions that limit the sale price to a formula based on the original purchase price plus annual appreciation caps. These restrictions exist in the proprietary lease and run with the shares
• Unsold shares: If no qualifying heir wants to keep the unit, the estate must sell through the co-op's standard process, subject to board approval of the buyer and any applicable price caps

HDFC rules are building-specific. I work with the estate attorney and the HDFC's managing agent to determine the exact rules governing a specific building before advising on listing strategy. Consult your estate attorney before making any assumptions about an HDFC inheritance.

Market-Rate Co-op Inheritance and Board Approval

For market-rate co-ops, the proprietary lease typically contains a "permitted transfer" provision that allows shares to pass to qualifying family members without board approval, within a defined period after death, often 1 to 2 years. This provision is intended to give heirs time to decide whether to keep or sell the unit.

If the heir qualifies as a permitted occupant under the lease and occupies the unit as a primary residence within the required period, the shares transfer without board review. If the heir does not occupy or does not qualify, or if the estate sells to a third-party buyer, the board approval process applies in full: financial package, interview, and board vote.

In my experience with estate co-op sales in Upper Manhattan, building management is generally cooperative when the Executor communicates early and clearly. Providing a copy of the Letters Testamentary and the estate attorney's contact information to the managing agent at the outset speeds up document production and avoids delays when the buyer's attorney requests the co-op package.

NY and Federal Estate Tax: When It Applies

Whether the estate owes tax is a question for your estate attorney and CPA. The key thresholds for 2026:

NYS has a "cliff" provision: if the estate value exceeds the NYS exemption by more than 5%, the exemption is phased out entirely and the full estate value is taxed. This makes the NYS estate tax particularly aggressive for estates in the $7 to $8 million range. Your estate attorney and CPA can model whether estate tax is payable and whether the sale timing affects the tax calculation. Consult a CPA before closing on all tax matters.

FIRPTA: Foreign Heirs and the 15% Withholding Rule

When an heir or beneficiary who is a non-U.S. person (foreign national or non-resident alien) receives an interest in NYC real property and sells it, the Foreign Investment in Real Property Tax Act (FIRPTA) requires the buyer to withhold 15% of the gross sale price and remit it to the IRS at closing. This withholding applies whether the foreign heir sells directly or whether the estate sells with the proceeds going to a foreign beneficiary.

Key FIRPTA points for estate sales:

• The withholding obligation falls on the buyer, but it reduces the net proceeds to the seller/estate
• A foreign heir or beneficiary can apply for a reduced withholding certificate from the IRS (Form 8288-B) to reduce withholding below 15% if the actual capital gain is lower than 15% of the sale price
• FIRPTA withholding is a prepayment of federal tax, not an additional tax. The heir files a U.S. tax return and receives a refund of any withholding that exceeds actual tax owed
• Estate tax treaties between the U.S. and other countries may affect the analysis

If any heir or beneficiary involved in the transaction is not a U.S. person, notify your estate attorney and the real estate closing attorney immediately. FIRPTA compliance must be structured before the contract is signed, not at closing. Consult your estate attorney and a CPA with international tax experience for guidance specific to the heir's tax situation.

Pre-Sale Appraisal and Documentation Checklist

Heirs and executors who prepare a complete documentation package before listing move significantly faster through the contract and due diligence process. For inherited NYC property, assemble the following before contacting a listing agent:
