Homes for Sale in Nassau County: A Complete Buyer's Guide to the Market

Nassau County is a seller's market that has been running hot for several years, and September 2026 is no exception. Median single-family home prices in Nassau County currently sit in the range of $750,000 to $800,000, depending on the area and property type, with many communities well above that figure. Inventory remains tight relative to demand, which continues to push prices upward and keep days on market short.

Prices and Inventory in September 2026

Condos and co-ops in Nassau County offer a lower entry point, with units in communities like Lynbrook, Valley Stream, and Rockville Centre starting in the mid-$300,000s and ranging up through the $500,000s for updated units near the LIRR. Detached single-family homes under $600,000 do exist in areas like Elmont, Uniondale, and parts of Hempstead, but competition for those listings is intense. Buyers who are pre-approved and ready to move quickly have a real advantage in this price band.

At the upper end, villages like Roslyn, Old Westbury, and Muttontown feature estates and large colonials priced from $1.5 million into the multi-millions, often on lots of one acre or more. The range across Nassau County is genuinely wide, which means there is housing stock for many different budgets, though the days of finding a move-in-ready Cape Cod under $500,000 near a train station are largely behind us.

How Nassau County Compares to Regional Trends

Nassau County's price appreciation is consistent with broader Northeast trends. According to reporting on Q3 2025 data, the Northeast saw the strongest price gains of any region in the country, with the national median single-family home price reaching $426,800 at that time. Nassau County's median sits well above that national figure, reflecting the premium that proximity to New York City commands. You can read more about those regional trends in this Inman report on Q3 2025 home price gains.

Nationally, inventory has been recovering in some markets, with active listings surpassing 820,000 in mid-2026, but Nassau County has not followed that trend as dramatically. Local supply remains constrained because Nassau County is essentially built out. There is very little undeveloped land left for new construction, so buyers are competing for a fixed pool of resale homes. That structural reality keeps prices supported even when national inventory loosens.

2. Housing Stock and Neighborhoods Across Nassau County

Nassau County covers roughly 453 square miles and contains three towns, two cities, and 64 incorporated villages, which means the housing stock varies considerably from one community to the next. Understanding the physical differences between areas helps buyers narrow their search before they start scheduling showings. The county divides broadly into the South Shore, the North Shore, and the mid-county communities that run through the Hempstead Plain.

The South Shore Communities

The South Shore stretches from Lawrence and Woodmere in the west through Oceanside, Baldwin, and Freeport, continuing east toward Merrick, Bellmore, and Wantagh. Homes here tend to be post-World War II construction: split-levels, ranches, and expanded Cape Cods on lots ranging from 40-by-100 feet up to quarter-acre parcels. Many communities back up to the bays and waterways that lead to Jones Beach Island, and boating is a practical part of daily life for residents with waterfront or canal-adjacent properties.

Freeport has a working waterfront with commercial marinas and the Nautical Mile, a stretch of seafood restaurants and fish markets along Woodcleft Canal. Wantagh sits adjacent to Jones Beach State Park, one of the most visited state parks in the country, with ocean beaches, a concert venue, and bike paths along the causeway. Homes in these South Shore communities currently range from roughly $550,000 for a modest ranch to over $1 million for a waterfront property with a dock.

The North Shore Communities

The North Shore along Long Island Sound includes Great Neck, Manhasset, Port Washington, Roslyn, Glen Cove, and Sea Cliff, among others. This stretch of Nassau County is characterized by older homes, many dating to the early twentieth century, on larger and more varied lots. You will find Tudor revivals, Colonials, and Victorian-era homes alongside mid-century contemporaries. The terrain is hilly compared to the flat Hempstead Plain, and many properties have water views over Manhasset Bay, Little Neck Bay, or Hempstead Harbor.

Great Neck is one of the more densely developed North Shore communities, with a walkable village center, multiple LIRR stations, and a mix of co-ops, condos, and single-family homes. Port Washington offers a compact downtown near the harbor, with ferry service to Connecticut operating from nearby communities. Prices on the North Shore generally run higher than the South Shore, with single-family homes in Manhasset and Roslyn Heights commonly listed between $900,000 and $2 million.

Mid-County and the Hempstead Plain

The central spine of Nassau County, running through Garden City, Mineola, New Hyde Park, Floral Park, and Westbury, sits on the flat glacial outwash plain that defines much of Long Island's interior. Garden City is one of the most architecturally distinctive communities in the county, laid out in the late nineteenth century as a planned community with wide, tree-lined streets, large Victorians, and a strong sense of civic design. The Nassau County Museum of Art is located in nearby Roslyn Harbor, and the Cradle of Aviation Museum in Garden City documents Long Island's role in aviation history.

Mineola and New Hyde Park offer smaller lots and more modest homes at lower price points, with strong LIRR access that makes them practical for commuters. Floral Park, which straddles the Nassau-Queens border, has a tight-knit village feel with Tudor and Colonial Revival homes from the 1920s and 1930s. Westbury and Carle Place are more mixed-use, with residential streets sitting alongside commercial corridors and easy access to the Meadowbrook and Wantagh parkways.

3. Commuting from Nassau County to New York City

Commute access is one of the defining factors in Nassau County real estate, and it directly influences pricing. Homes within walking distance of an LIRR station consistently command a premium over comparable homes that require a car to reach the train. Understanding the commute landscape before you search helps you make a more informed decision about where to focus.

Long Island Rail Road Routes and Travel Times

The LIRR runs multiple branches through Nassau County, with Penn Station and Grand Central Madison in Midtown Manhattan as the primary Manhattan terminals. Travel times from Nassau County stations to Penn Station vary considerably. Floral Park and New Hyde Park are roughly 30 to 35 minutes by express train. Mineola and Garden City run about 35 to 40 minutes. Hicksville, a major transfer hub on the Main Line, is approximately 45 to 50 minutes. Stations farther east, like Wantagh or Bellmore, add another 10 to 15 minutes on top of that.

The Port Washington Branch serves the North Shore communities of Great Neck, Manhasset, and Port Washington, with express trains reaching Penn Station in roughly 35 to 50 minutes depending on the station. The Far Rockaway and Long Beach branches serve the southwestern corner of Nassau County, with Long Beach to Penn Station taking approximately 55 minutes on a local train. Monthly LIRR passes from Nassau County stations currently range from roughly $230 to $320 depending on the zone.

Driving and Other Options

Driving into Manhattan from Nassau County is possible but unpredictable. The Long Island Expressway (I-495), the Northern State Parkway, and the Southern State Parkway all funnel traffic into Queens and Brooklyn. During peak hours, a drive from Garden City to Midtown can take anywhere from 50 minutes to well over 90 minutes. Many Nassau County residents use a hybrid approach: driving to a park-and-ride lot near an LIRR station and taking the train from there.

For commuters working in other parts of Long Island rather than the city, Nassau County is also well-positioned. Major employment centers like the Mitchel Field area in Uniondale (home to Nassau University Medical Center and NYCB Live arena), the Hauppauge Industrial Park in Suffolk County, and the various hospital campuses throughout the county are all accessible by car within 20 to 45 minutes from most Nassau addresses.

4. The Buying Process in Nassau County: What to Expect

Buying a home in Nassau County follows New York State contract law, which differs from many other states in meaningful ways. Attorneys are required in New York real estate transactions, and the contract is not binding until both parties have signed and attorneys have exchanged fully executed copies. That review period, sometimes called the attorney review period, typically takes five to ten business days after an offer is accepted.

Getting Pre-Approved and Making Offers

In Nassau County's competitive market, a pre-approval letter from a lender is essentially required before a listing agent will take your offer seriously. Many sellers, especially those listing in the $700,000 to $1 million range, receive multiple offers within the first week. Buyers who are pre-approved with a local lender familiar with Nassau County transactions tend to move through the process more smoothly than those using out-of-area lenders who are less familiar with New York closing timelines.

Offer letters in Nassau County typically include the purchase price, proposed closing date, and any contingencies such as mortgage, inspection, or appraisal. Waiving contingencies is increasingly common in competitive bidding situations, though buyers should weigh that decision carefully with their attorney and agent. Wilson Vernelly of Corcoran SRG Residential has guided many buyers through exactly these negotiations and can help you structure an offer that is competitive without taking on unnecessary risk.

Closing Costs and Transfer Taxes in New York

Closing costs in Nassau County are higher than the national average, and buyers should budget accordingly. On a $750,000 purchase, total closing costs for a buyer using a mortgage typically fall between $18,000 and $28,000, depending on lender fees, title insurance, and whether the property is subject to New York's mansion tax.

New York State's mansion tax applies to any residential purchase of $1 million or more, starting at 1% of the total purchase price and rising on a graduated scale for higher-priced properties. On a $1.2 million purchase, that tax alone adds $12,000 to the buyer's costs. New York also charges a mortgage recording tax, which in Nassau County runs approximately 1.05% of the loan amount for loans under $500,000 and 1.3% for loans above that threshold. These are costs that many buyers relocating from other states do not anticipate.

Property Taxes and STAR Exemptions

Property taxes in Nassau County are among the highest in the United States, and they are a critical part of any affordability calculation. Annual property tax bills on a single-family home in Nassau County commonly range from $10,000 to $20,000, with many communities in the $12,000 to $16,000 band for a median-priced home. Taxes vary by school district, special district charges (water, fire, sanitation), and the assessed value set by the Nassau County Department of Assessment.

New York's School Tax Relief (STAR) program offers a partial exemption on school taxes for owner-occupied primary residences. The Basic STAR exemption is available to homeowners with household income under $500,000, while the Enhanced STAR is available to homeowners 65 and older meeting income thresholds. For a newly purchased home, buyers register for STAR through the New York State Department of Taxation and Finance rather than through the local assessor. The savings range from roughly $300 to over $1,000 annually depending on the program and the school district.

Nassau County also has a formal property tax grievance process that allows homeowners to challenge their assessed value annually. Many Nassau County homeowners file grievances regularly, and a significant percentage receive reductions. Your real estate attorney or a tax certiorari firm can walk you through this process after closing.

5. What Else to Know Before You Search for Homes for Sale in Nassau County

Beyond prices and commutes, a few other practical factors shape the Nassau County buying experience in ways that matter once you are living there. Nassau County is served by a patchwork of incorporated villages, each with its own building department, code enforcement, and permit requirements. If you are buying a home and plan to renovate, permits must be pulled through the village or town where the property sits, not through Nassau County itself. This can affect timelines and costs for projects ranging from adding a deck to converting a garage.

Flood Zones and Insurance Considerations

A meaningful portion of Nassau County's housing stock sits in FEMA-designated flood zones, particularly along the South Shore bays, the barrier island communities, and low-lying areas near tidal waterways. Homes in Special Flood Hazard Areas (SFHA) require flood insurance if financed with a federally backed mortgage, and annual premiums can range from a few hundred dollars for elevated homes to several thousand dollars for properties with lower base flood elevations. Always check the FEMA Flood Map Service Center for any property you are seriously considering, and ask the listing agent for the current flood insurance certificate if one exists.

Oil Heat and Underground Tanks

A large percentage of Nassau County homes built before the 1980s were originally heated with oil, and many still are. Some of those homes have underground oil storage tanks (USTs) that were abandoned in place when the heating system was converted to gas. An abandoned underground tank that has leaked can create an environmental liability that is expensive to remediate and can complicate financing. A good home inspector will flag any signs of a former UST, and buyers should ask sellers directly about tank history as part of due diligence.

Parks, Beaches, and Public Amenities

Nassau County residents have access to an extensive network of parks and recreational facilities through the Nassau County Department of Parks, Recreation and Museums. The county operates Eisenhower Park in East Meadow, a 930-acre facility with golf courses, tennis courts, an aquatic center, and athletic fields. Nickerson Beach Park in Lido Beach offers ocean swimming, camping, and cabana rentals. The Nassau Veterans Memorial Coliseum in Uniondale hosts concerts and events. County residents pay discounted rates for many of these facilities with a Nassau County resident card.

Beyond county parks, many incorporated villages maintain their own parks and beaches that are restricted to village residents. If access to a specific beach or park is important to you, verify whether the property you are considering falls within that village's boundaries. In some cases, a home one block outside a village line means no access to that village's beach, even if the home is physically adjacent to it.

The broader Northeast housing market context supports the durability of Nassau County prices. National data from the NAR showed that home prices increased in 73% of metro areas in the fourth quarter of 2025, and the New York metro area was among the markets sustaining gains. For buyers, that means waiting for prices to fall significantly is not a strategy that has paid off in this market.
