A residential real estate transaction in New York follows the same general arc whether the property is a Brooklyn brownstone, a Manhattan co-op, a Queens two-family, or a single-family house in Great Neck — but the details diverge in ways that matter financially. New York City’s five boroughs and Nassau County, where Great Neck sits, are governed by the same state laws: the same attorney-state framework, the same state transfer tax, the same mansion tax on purchases of $1 million or more. Below that shared foundation, however, the local tax structures, recording systems, and market dynamics are meaningfully different. A seller in Manhattan pays the NYC Real Property Transfer Tax on top of the state transfer tax. A seller in Great Neck does not. A buyer in Great Neck navigating Nassau County’s property tax assessment system faces a process that has no equivalent in the five boroughs. The closing-cost math, the diligence checklist, and the practical considerations differ by location even when the underlying legal framework is the same.
This guide covers buying and selling property in both NYC’s five boroughs and Great Neck / Nassau County, with a focus on the legal and transactional realities rather than market statistics or pricing trends. It is written by a New York City closing attorney whose firm represents buyers and sellers across the metropolitan area, including clients purchasing or selling in Great Neck and surrounding Nassau County communities. The firm provides bilingual English and Farsi representation — relevant for the significant Persian community in Great Neck, and available to any client who prefers it. Yazdi Law is based in Manhattan and serves Long Island clients; the firm does not maintain a Great Neck office.

New York Is an Attorney-State: Why That Matters Everywhere from Manhattan to Great Neck
New York requires substantive attorney involvement on both sides of a residential real estate transaction. This is true in all five boroughs and equally true in Nassau County. Unlike states where title companies or escrow agents run the closing process, New York’s structure assigns the core transactional work to the attorneys: the seller’s attorney drafts the contract of sale and prepares all transfer documents; the buyer’s attorney reviews and negotiates the contract, coordinates due diligence and title, and represents the buyer at closing. Title insurance is provided by a separate title company, which issues its own policy but does not perform the legal work.
This attorney-state framework means that buyers and sellers in Great Neck engage counsel in the same structural way as buyers and sellers in Manhattan or Brooklyn. The attorney fees are comparable. The contract negotiation process follows the same pattern. The difference is not in whether attorneys are involved — they are, in both locations — but in the local tax, recording, and regulatory details that the attorneys handle on behalf of their clients.

The Five Boroughs: What Buyers and Sellers Should Know
Manhattan, Brooklyn, Queens, the Bronx, and Staten Island — Shared NYC Rules
All five boroughs operate under a common set of New York City rules that distinguish NYC real estate from the rest of the state. The NYC Real Property Transfer Tax (RPTT) applies to every residential sale in the five boroughs: 1% on sales under $500,000 and 1.425% on sales of $500,000 or more. This is in addition to the NY State transfer tax of 0.4%. The RPTT is a city-level tax that does not exist outside New York City — a distinction that matters when comparing closing costs between NYC and Nassau County.
ACRIS (the Automated City Register Information System) serves as the universal public records system across all five boroughs, providing free access to recorded deeds, mortgages, liens, and other property documents. Co-operative apartments dominate Manhattan’s housing stock and are common in parts of Brooklyn and Queens — a building type that carries its own legal framework involving board approval, share transfers, and proprietary leases rather than deeds.
Each borough has its own character. Manhattan’s residential market is heavily co-op and condo, with single-family homes rare outside a few neighborhoods. Brooklyn offers a mix of brownstones, co-ops, condos, and multi-family buildings. Queens has more single-family and two-family homes alongside co-op and condo developments, and remains one of the more accessible entry points for buyers in the city. The Bronx has an expanding inventory of new condo construction alongside established co-op and multi-family stock. Staten Island’s housing stock is predominantly single-family homes, with a suburban feel that is closer in character to parts of Long Island than to the other boroughs.
NYC Closing Costs at a Glance
Buyer closing costs in NYC typically total 3–6% of the purchase price, driven by mortgage recording tax, title insurance, mansion tax (on purchases over $1 million), attorney fees, and lender-related charges. Seller closing costs typically total 8–10% of the sale price, with brokerage commissions accounting for the largest component, followed by the RPTT and state transfer tax. For a comprehensive breakdown of buyer and seller costs with current figures and official source links, see our 2026 resource guide for buying and selling residential property in New York. The figures cited there were current as of that guide’s publication date; verify at the NY State Department of Taxation and Finance and the NYC Department of Finance before relying on any specific calculation.
Great Neck and Nassau County: A Different Set of Rules
Where Great Neck Fits
Great Neck is not a single municipality. It is a cluster of villages — including Great Neck, Great Neck Estates, Great Neck Plaza, Kensington, Kings Point, Thomaston, Saddle Rock, and Russell Gardens — plus unincorporated areas, all within the Town of North Hempstead in Nassau County, on Long Island’s North Shore. The Great Neck school district is one of the primary unifying features and one of the area’s strongest draws for buyers: it consistently ranks among the top public school systems in New York State.
The Long Island Rail Road connects Great Neck to Penn Station in approximately 35 minutes, making it a well-established commuter community for Manhattan workers. The housing stock skews toward single-family homes, with a range from modest colonials to substantial waterfront properties. Some co-ops and condos exist near the LIRR station and along the commercial corridors. Great Neck is also home to a large and long-established Iranian-American community, a fact that is relevant both for buyers seeking that community and for the availability of Farsi-speaking professional services in the area.
How Nassau County Transactions Differ from NYC
The most significant financial difference between a Nassau County transaction and an NYC transaction is the absence of the NYC RPTT. The city transfer tax of 1%–1.425% simply does not apply in Nassau County. On a $1.5 million sale, that represents a savings of roughly $21,000 for the seller compared to a sale at the same price in NYC. The NY State transfer tax of 0.4% still applies, and the mansion tax still applies statewide to residential purchases of $1 million or more — verify current brackets at the NY State Department of Taxation and Finance.
Nassau County has its own mortgage recording tax structure, which differs from NYC’s. The mortgage recording tax in Nassau County is generally lower than in the five boroughs, though the exact rate depends on the loan amount and property type. Recording of deeds and mortgages is handled through the Nassau County Clerk’s office, not through ACRIS. The recording process and fee schedule are different from NYC, and attorneys practicing in Nassau County are familiar with the county-specific requirements.
Property taxes in Nassau County deserve particular attention. Nassau’s property tax system operates differently from NYC’s, with assessments administered at the county level and taxes levied by multiple overlapping jurisdictions — county, town, school district, and village. The school district component is typically the largest. Nassau County has undergone significant assessment changes in recent years, and the assessment grievance process — administered through the Nassau County Assessment Review Commission (ARC) — is a routine part of property ownership in the county. Buyers should review the property’s current assessment and recent tax history, and sellers should be prepared to answer questions about whether the assessment has been grieved and what the current tax burden reflects relative to market value.
The school district is a major value driver in Great Neck real estate. The Great Neck Union Free School District’s reputation directly affects property values, and buyers should understand that the school tax component of the annual property tax bill is substantial. For buyers comparing a Queens home to a Great Neck home at a similar price point, the property tax difference can be significant, and the school district quality is often the reason.
Co-op, Condo, or House in Great Neck
Great Neck’s housing market is dominated by single-family homes, which is a fundamental difference from NYC’s co-op- and condo-heavy inventory. Buying a house involves a conventional real property purchase: the buyer receives a deed in fee simple, there is no board approval, and the owner has full autonomy over the property subject to local zoning and any applicable homeowner association rules. A property survey is standard for house purchases and identifies boundaries, easements, encroachments, and any structural encroachments. Title insurance covers the property itself as real property, not shares in a corporation. Oil tank disclosures are a consideration in older Long Island homes — underground oil tanks, if present, can create environmental liability and should be identified during the inspection phase.
Where co-ops exist in Great Neck — primarily in buildings near the LIRR station — the board approval process applies as it does in NYC co-ops, though the process in smaller suburban co-op buildings is often less formal than in large Manhattan buildings. The purchase is still a share transaction with a proprietary lease, and the buyer’s attorney must review the building’s financials, offering plan, and proprietary lease in the same manner as for a NYC co-op purchase.
Buying: The Process Step by Step (NYC and Great Neck)
The buying process in New York follows the same general stages whether the property is in the five boroughs or in Nassau County: offer, attorney-reviewed contract, due diligence and financing, and closing. What changes between locations is the specific diligence involved and the cost structure at closing.
The process begins when a buyer makes an offer, which in New York is typically non-binding until the contract of sale is executed by both parties. Once the seller accepts the offer, both sides engage their attorneys. The seller’s attorney drafts the contract; the buyer’s attorney reviews and negotiates it. The contract phase typically takes 5 to 10 business days and is the most legally significant phase of the transaction. Earnest money deposits in New York are typically 10% of the purchase price, held in escrow by the seller’s attorney — substantially higher than the 1–3% customary in most other states.
After contract execution, the buyer’s attorney orders a title search and the buyer pursues mortgage financing. For NYC co-op or condo purchases, building-level due diligence includes review of financial statements, board minutes, and the offering plan. For a Great Neck house purchase, the emphasis shifts to a physical inspection of the property, a survey, and review of the certificate of occupancy and any permits. Environmental considerations — particularly oil tanks and lead paint in pre-1978 homes — are part of the standard Long Island diligence checklist. The CFPB’s homebuying resources provide useful general guidance on mortgage disclosures and the financing timeline.
At closing, the buyer signs all transfer and financing documents, pays the balance of the purchase price and closing costs, and receives the deed (or, for co-ops, the share certificate and proprietary lease). In NYC, closings are typically held at an attorney’s or title company’s office in Manhattan. In Nassau County, closings are often held at the title company’s local office. For a detailed walkthrough of each stage, see our complete resource guide for buying and selling in New York.
Selling: The Process Step by Step (NYC and Great Neck)
The selling process similarly follows a shared structure. The seller engages a listing agent and a seller’s attorney, ideally before the property goes on the market. Document preparation — assembling the deed, prior title policy, tax records, mortgage payoff information, and any building documents — is best completed before listing to avoid delays once an offer is accepted.
After accepting an offer, the seller’s attorney drafts the contract of sale and coordinates with the buyer’s attorney through the negotiation phase. The seller must respond to due diligence requests, resolve any title objections, and obtain mortgage payoff letters. New York sellers of one-to-four-family residential properties must provide a Property Condition Disclosure Statement under Real Property Law Article 14 or credit the buyer $500 at closing.
At closing, the seller’s attorney prepares the deed, transfer tax returns, and all required affidavits. The key difference between an NYC closing and a Nassau County closing on the seller’s side is the transfer tax exposure: an NYC seller pays both the state transfer tax (0.4%) and the NYC RPTT (1%–1.425%), while a Nassau County seller pays only the state transfer tax. For sellers of properties acquired below current market value, capital gains exposure is a consideration in both locations — IRS Publication 523 covers the primary residence exclusion and gain calculations. Non-U.S.-citizen sellers are subject to FIRPTA withholding in all jurisdictions.
The Persian / Iranian-American Community and Great Neck Real Estate
Great Neck is home to one of the largest Iranian-American communities in the northeastern United States. The community has deep roots in the area, with families established across the Great Neck villages for decades. Persian cultural institutions, businesses, restaurants, and community organizations are part of the daily fabric of Great Neck life. For buyers from the Persian diaspora, the presence of this community is often a primary reason for choosing Great Neck — the schools, the commute to Manhattan, and the ability to raise a family within a familiar cultural context.
In a real estate transaction, language matters. A purchase contract, mortgage commitment letter, title report, and closing statement are complex documents with terms that carry specific legal consequences. For Farsi-speaking buyers and sellers, working with an attorney who can discuss these documents in their preferred language reduces the risk of misunderstanding a contingency deadline, a financing condition, or a contractual obligation. This is not a matter of translation convenience — it is a practical safeguard in a transaction where the earnest money deposit alone is typically 10% of the purchase price.
Certain transactional patterns that arise in the Persian community — family financing arrangements, gift funds from relatives for down payments, multi-generational purchases where parents and children co-purchase a home — require specific documentation to satisfy mortgage lender requirements. Gift letters, source-of-funds documentation, and co-borrower structuring must be handled correctly to avoid delays at the underwriting stage. An attorney familiar with these patterns can coordinate with the lender and ensure that the documentation satisfies both legal and lender requirements from the outset. Yazdi Law provides bilingual English and Farsi representation for buyers and sellers across NYC and Long Island — see our Iranian attorney services page for more about how we serve the Persian community.
A Note on the 2026 Market (Dated Context)
As of June 2026, the New York metropolitan real estate market reflects an interest-rate environment that has evolved significantly over the past several years, with inventory levels and buyer demand varying by neighborhood and property type. This post does not include specific price data or market predictions because those figures change month to month and would make the legal and procedural information here appear dated. Buyers and sellers should consult their real estate agent and current market data from reliable sources for pricing context relevant to a specific transaction.
When to Hire a Real Estate Attorney in NYC or Long Island
Because New York is an attorney-state, the question is not whether to retain counsel but when to engage and what value counsel provides at each stage. The answer, for both buyers and sellers, is before signing the contract. The contract of sale is the central document of a New York residential transaction, and once it is executed, the terms are binding. Engaging an attorney after contract execution limits the attorney’s ability to negotiate terms that protect the client’s interests.
Attorney involvement matters most in several specific contexts: co-op purchases, where building-level due diligence and board application strategy are critical; properties with title clouds or prior unpermitted work, where the attorney must identify and resolve issues before closing; Nassau County transactions where the property tax assessment may be out of line with market value and a grievance may be warranted; foreign buyers navigating FIRPTA and financing issues; and multi-generational or family-financed purchases where gift documentation and co-borrower structuring require careful coordination with the lender. Bilingual English and Farsi representation is available for clients who prefer it.
Our real estate practice handles purchases and sales across the five boroughs and Long Island, including Nassau County. For residential closings specifically — including flat-fee structures and what to expect at each stage — see our residential closings page. The attorneys at Yazdi Law work with both buyers and sellers, and the firm’s approach emphasizes direct attorney communication throughout the transaction.
