A Roslyn sale follows New York law like any other, but three local facts shape it. The permit file for your house sits with whichever government runs the building department for your address. Your property taxes come from more than one office on more than one calendar. And the State transfer tax, which the seller owes by law, is normally paid at the closing table.

Pricing is covered in the North Shore home value guide, and choosing who represents you in how to choose a listing agent in Roslyn.

What Are the Steps to Sell a House in Roslyn, NY?

A Roslyn sale moves through nine steps, and in practice neither side is bound until the attorneys have negotiated the contract and both parties have signed it.

Step	What happens	Who handles it
1. Prepare	Request your building department file; gather tax bills, survey and deed; price from closed sales.	You and your listing agent
2. List	You receive New York’s agency disclosure form before signing a listing agreement (Real Property Law 443).	Listing agent
3. Accept an offer	Price, down payment, mortgage terms and target closing date go to both attorneys.	Agents, then attorneys
4. Disclose	The Property Condition Disclosure Statement goes to the buyer before the buyer signs; add the federal lead disclosure for a pre-1978 home.	You, with your attorney
5. Contract	Your attorney drafts, the buyer’s attorney negotiates, the buyer signs and pays the down payment into escrow, then you sign.	Both attorneys
6. Mortgage commitment	The buyer’s lender appraises and issues a written commitment.	Buyer and lender
7. Title search	The title company searches liens, permits and certificates of occupancy.	Buyer’s title company
8. Closing	You sign the deed and transfer tax return, your mortgage is paid off, and taxes are adjusted.	Attorneys and title closer
9. After closing	Your lender arranges to record the satisfaction of your mortgage within 30 days.	Your lender

Steps 2, 4 and 9 rest on Real Property Law 443 and 462, the US EPA lead rule and RPAPL 1921. The other steps describe common Long Island practice as of October 2026.

How Long Does It Take to Sell a House in Nassau County?

From an accepted offer to closing, a Roslyn-area sale commonly takes about two to three months. No government office publishes an official figure, so the spans below are the team’s working practice, not a rule.

Stage	Common span	What stretches it
Accepted offer to signed contract	About one to two weeks	Inspection findings, attorney negotiation
Contract to mortgage commitment	About three to six weeks	The appraisal, the buyer’s documents
Commitment to closing	About two to four weeks	Title objections, open permits, a missing certificate of occupancy, co-op board review
Accepted offer to closing	About two to three months	Any of the above

The Scout Residential Team’s practice on the North Shore as of October 2026; not a published statistic.

In the team’s experience, the two things that most often push a Roslyn-area closing date are an open permit and a missing certificate of occupancy. Both are fixable before you list.

Do You Need a Lawyer to Sell a House in New York?

In practice, yes. On Long Island the seller’s attorney drafts the contract of sale, the buyer’s attorney negotiates it, and attorneys run the closing. Your agent negotiates price and terms but does not give legal advice: the agency disclosure form under Real Property Law 443 tells consumers, “If you need legal, tax or other advice, consult with a professional in that field.”

The accepted offer is not the contract. The binding document is the contract your attorney drafts, which sets the down payment, the mortgage contingency, the closing date and who keeps any pending tax refund. The buyer usually signs first and delivers the down payment, commonly 10 percent, which your attorney holds in escrow; the contract binds once you sign and it is delivered. Your attorney also prepares the deed and the transfer tax return, Form TP-584, and orders your payoff.

What Does a New York Seller Have to Disclose?

A New York seller of a house with one to four dwelling units must complete, sign and deliver the Property Condition Disclosure Statement to the buyer or the buyer’s agent before the buyer signs a binding contract, under Real Property Law section 462. A copy signed by both sides is attached to the contract, and the parties may still agree to a sale “as is.”

What Changed on March 20, 2024

Until March 20, 2024, a seller could skip the form and give the buyer a $500 credit instead. Chapter 484 of the Laws of 2023, signed September 22, 2023, deleted that credit from Real Property Law section 465 effective March 20, 2024, and added flood questions. Section 465 now makes a seller liable for the buyer’s actual damages for a willful failure to meet the article’s requirements.

What the Form Asks That Matters in Roslyn

• Question 9: are there certificates of occupancy related to the property, and if not, why.
• Questions 10 to 17: FEMA flood zones, flood insurance, elevation certificates, flood claims and disaster assistance.
• Question 36: the type of sewage system and, for a cesspool or septic system, its age and the date it was last pumped.

You answer from actual knowledge and need not inspect the house or search public records, but if you learn something before closing that makes an answer materially inaccurate, you must deliver a revised statement as soon as practicable. Condominium units and co-op apartments are not covered, and Real Property Law section 463 exempts certain transfers, among them a transfer by a fiduciary administering an estate or trust and a transfer between co-owners.

For most housing built before 1978, the US EPA lead disclosure rule adds a second step: give the buyer the EPA’s lead hazard pamphlet, disclose any known lead-based paint, include a lead warning statement, and allow a 10-day inspection period, which the parties may change in writing.

Do You Need a Certificate of Occupancy to Sell a House in Nassau County?

In practice, yes. The disclosure form asks about certificates of occupancy and the buyer’s title company searches the building department file, so every structure and finished space should be covered by a certificate of occupancy or completion before you go to contract. The Village of North Hills says a permit without its certificate “is considered an ‘open permit’ and it may affect your ability to sell your residence.”

Who Holds the Permit File for Your Address?

Inside each Roslyn-area village in the table below, the village holds the permit file. The Town of North Hempstead building department covers only the Town’s unincorporated areas, such as Roslyn Heights. A Roslyn mailing address does not tell you which applies; your tax bills do, because incorporated villages collect their own village taxes. The towns, villages and hamlets guide explains the map.

Place	Government	Who holds the permit and certificate file
Village of Roslyn	Incorporated village	Village Building Department, 1200 Old Northern Blvd., (516) 621-1961 ext. 106
Roslyn Estates	Incorporated village	Village of Roslyn Estates, 25 The Tulips, (516) 621-3541
Roslyn Harbor	Incorporated village	Village Building Department, 500 Motts Cove Road South, (516) 621-0368
East Hills	Incorporated village	Village Building Department, Village Hall, 209 Harbor Hill Road, (516) 621-5600
Flower Hill	Incorporated village	Village Building Department, 1 Bonnie Heights Road, Manhasset, (516) 627-5000
North Hills	Incorporated village	Village Building Department, One Shelter Rock Road, (516) 627-3690
Roslyn Heights	Unincorporated, Town-governed	Town of North Hempstead building department, (516) 869-6311 or 311; records through the MyToNH portal

How to Find and Fix Open Permits Before a Buyer Does

The buyer’s title company usually orders municipal searches from the building department that holds your file, so anything open surfaces during the contract period. Request your file before you list and compare it room by room with the house. The Village of Roslyn requires a certificate of occupancy or completion within thirty days of finishing permitted work, holds the owner responsible for it, may require an updated survey, and lists finished basements and attics among work that needs a permit; exterior work in its Historic District needs the Historic District Board’s approval. The Village of Roslyn Harbor issues permits to “Maintain and Legalize Any Building, Structure or Space Constructed or Installed Without a Permit.” If your house predates certificates of occupancy, ask the building department what it issues for an older structure. The Town’s Receiver of Taxes also notes that improvements, including unreported work done before a sale, can raise assessed value beyond the 6 percent cap.

What Are a Seller’s Closing Costs in Nassau County?

A Nassau County seller owes the New York State transfer tax by law and, by contract or custom, pays the commission, the seller’s attorney, the mortgage payoff and its satisfaction recording, and the tax adjustment. The buyer, not the seller, pays the mansion tax.

Cost	Who pays	Rate or rule, as of October 2026
NYS transfer tax (Tax Law 1402)	Seller by law; the buyer if the contract says so, or if the seller does not pay or is exempt	$2 for each $500 of the price or fraction of $500 ($4 per $1,000), on Form TP-584 within 15 days of deed delivery
Mansion tax (Tax Law 1402-a)	Buyer by law; the seller only if the buyer does not pay or is exempt	1 percent of the price on a residential sale of $1 million or more
Commission	As set in your listing agreement	Fully negotiable and not set by law
Seller’s attorney	You	Negotiable; no official rate is published
Mortgage payoff and satisfaction	You; the recording customarily falls to the seller	County Clerk schedule for a satisfaction: $40 recording fee, $300 per block, $5 per page
Property tax adjustment	A credit or a charge to you	Set by the levy periods and the closing date
Nonresident estimated income tax	Sellers who are not New York residents	Form IT-2663 (IT-2664 for a co-op) unless an exemption applies

Who Pays the Transfer Tax in New York?

The seller. The NYS Department of Taxation and Finance says the base tax is “paid by the grantor (seller).” The buyer pays it only if the contract of sale says so, or if the seller does not pay or is exempt. The higher supplemental rates apply to property in New York City, not in Nassau County.

Who Pays the Mansion Tax?

The buyer. The 1 percent tax under Tax Law 1402-a applies to a residential sale of $1 million or more and “shall be paid by the grantee.” The seller pays only if the buyer does not or is exempt.

How Are Nassau County Property Taxes Split at Closing?

Each tax half covers a fixed six-month period, and the attorneys credit or charge you for the days on either side of the closing date. In the Town of North Hempstead the Receiver of Taxes bills and collects County, Town, school and special district taxes. The school tax year runs July 1 to June 30; the general tax year runs January 1 to December 31.

Tax half	Due, then last day without penalty	Period it covers
First-half school tax, 2026-2027	October 1, 2026; November 10, 2026	July 1 to December 31
First-half general tax, 2027	January 1, 2027; February 10, 2027	January 1 to June 30
Second-half school tax, 2026-2027	April 1, 2027; May 10, 2027	January 1 to June 30
Second-half general tax, 2027	July 1, 2027; August 10, 2027	July 1 to December 31

Village taxes are separate: incorporated villages collect their own, may use assessed values that differ from the County roll, and set their own dates. The Village of Roslyn’s taxes are due June 1, payable without penalty through July 1. Exemptions such as STAR generally do not transfer at closing, and when an exemption is removed after a sale the County may add prorated restored taxes to a later bill, up to two years later.

Can You Sell a House While a Nassau County Tax Grievance Is Pending?

Yes, but a reduction often lands after you have sold. The Assessment Review Commission, an independent County agency, takes applications from January 4 to March 1, 2027. ARC says a filing in that window affects the October 2028 school bill and the January 2029 general bill, with determinations by March 31, 2028.

ARC’s forms add three facts. A buyer under contract can file as a “Contract Vendee.” An owner who settles warrants the property has not been sold or placed under contract since filing, except as disclosed to ARC in writing. And the County Treasurer refunds overpaid taxes to the applicant. Tell your attorney about a pending grievance at listing so the contract says who keeps any refund. The Village of Roslyn holds its own grievance day, the third Tuesday in February, for the village tax.

Selling a Co-op or Condominium in the Roslyn Area

A co-op or condominium sale follows most of the same steps, with three differences. The Property Condition Disclosure Statement does not apply. The mansion tax does, at $1 million or more. And a co-op sale typically needs the board’s approval under the building’s own proprietary lease and bylaws, so ask the managing agent for the board package requirements at listing; in our practice the board review is often the longest stage of a co-op sale.
