What Is the Average Home Price in Nassau County New York Right Now in September 2026

The median home price in Nassau County, New York sits at approximately $860,000 to $880,000 in September 2026. That figure reflects closed sales across all property types, including single-family homes, condos, and co-ops. Single-family detached homes, which make up the bulk of Nassau County's housing stock, are tracking closer to $900,000 at the median when isolated from attached units.

Where the County Number Comes From

Nassau County spans 453 square miles and includes three towns, two cities, and 64 incorporated villages. That geographic and economic diversity means the county-wide median is a starting point, not a destination. A co-op in Hempstead can sell for under $200,000 while a colonial in Manhasset can close above $2 million, and both transactions feed into the same countywide average. Understanding price by community is far more useful when you are making an actual buying or selling decision.

You can track the countywide median listing price over time through the Federal Reserve Bank of St. Louis FRED database, which pulls from MLS listing data for Nassau County and updates monthly. That resource is useful for spotting directional trends across multiple years rather than relying on any single month's snapshot.

How September 2026 Compares to a Year Ago

Nassau County home prices are up roughly 5 to 7 percent year over year as of September 2026, compared to September 2025. That pace is a modest deceleration from the double-digit annual gains seen between 2021 and 2023, but it still represents meaningful appreciation. A home that sold for $820,000 in September 2025 would likely be priced near $870,000 to $880,000 today if all else were equal. The market has not reversed; it has simply shifted from a sprint to a steady walk.

Back in June 2026, Nassau County hit a median of $852,000 according to local market tracking, with the 30-year fixed mortgage rate sitting at 6.52 percent at that time. By September 2026, rates have edged slightly, and prices have continued their upward drift. The combination of limited supply and persistent demand continues to put upward pressure on values.

2. Price Ranges Across Nassau County Communities

Nassau County's home prices vary considerably depending on which community you are looking at. The county stretches from the Queens border at the Nassau-Queens line all the way to the Oyster Bay and North Hempstead shorelines, and prices reflect both geography and housing stock. Here is a practical breakdown by area.

Western Nassau: Hempstead, Valley Stream, and Elmont

Western Nassau communities offer the county's most accessible price points. In Hempstead, co-ops and smaller attached homes trade in the $150,000 to $350,000 range, while single-family homes on the village's residential streets typically fall between $400,000 and $600,000. Valley Stream, which sits along the Queens border and offers Long Island Rail Road access at Valley Stream station with a roughly 35-minute ride to Penn Station, sees single-family homes in the $550,000 to $750,000 range. Elmont, known for its proximity to UBS Arena and Belmont Park, has seen price growth in recent years, with most single-family sales landing between $500,000 and $700,000.

Mid-County: Garden City, Mineola, and Westbury

Garden City sits at the geographic and commercial heart of Nassau County, and its housing stock reflects that position. Tudor colonials, center-hall colonials, and large Victorians on tree-lined streets define the village. Median sale prices in Garden City run from $1.1 million to $1.4 million in September 2026, with larger homes on oversized lots pushing well above $2 million. If you are considering Garden City, the article on finding a highly reviewed listing agent in Garden City covers what to look for in representation there.

Mineola, which serves as the Nassau County seat, offers a mix of cape cods, ranches, and split-levels from the postwar era. Prices there generally range from $600,000 to $850,000 for single-family homes. Westbury, adjacent to Mineola, has a similar price range and a walkable downtown area along Post Avenue. Both communities have Long Island Rail Road stations with approximately 40-minute service to Manhattan.

North Shore: Manhasset, Great Neck, and Port Washington

The North Shore communities command some of the highest prices in Nassau County. Manhasset, situated along the Manhasset Bay and home to the Americana Manhasset shopping corridor, sees median sale prices in the $1.5 million to $2 million range for single-family homes, with significant inventory above $3 million. Great Neck, which includes multiple incorporated villages such as Great Neck Plaza, Kensington, and Kings Point, spans a wide price band. Entry-level co-ops in the Great Neck area start around $200,000, while waterfront estates in Kings Point can exceed $10 million. The typical single-family home in the broader Great Neck area trades between $900,000 and $1.8 million.

Port Washington, perched on the Manhasset Neck peninsula along Manhasset Bay, offers colonial and cape cod homes on quarter-acre to half-acre lots. Median prices there sit between $950,000 and $1.3 million in September 2026. The Port Washington LIRR branch delivers riders to Penn Station in roughly 45 to 50 minutes, which contributes to sustained demand in that corridor.

South Shore: Rockville Centre, Lynbrook, and Oceanside

The South Shore runs along Reynolds Channel, the South Bay, and ultimately Jones Beach, and its communities offer a distinct housing character. Rockville Centre has a compact, walkable village center along North Village Avenue and a mix of tudors, capes, and colonials. Median prices in Rockville Centre are in the $750,000 to $1.05 million range. Lynbrook, directly to the east, has a similar housing stock at a slightly lower price band, with most single-family sales between $650,000 and $900,000. Oceanside, which borders the water and sits near Loop Parkway and Jones Beach State Park, trades in the $600,000 to $850,000 range.

3. What Is Driving Nassau County Home Prices Right Now

Three forces are keeping Nassau County home prices elevated in September 2026: a structural shortage of available homes, a mortgage rate environment that discourages move-up sellers from listing, and continued demand from buyers connected to New York City. Each of these deserves a closer look because they affect what buyers should expect and what sellers can realistically achieve.

Inventory Constraints

Nassau County is a built-out suburban county with very little developable land remaining. New construction is limited to infill projects, teardown rebuilds, and the occasional conversion of commercial property. That means supply additions are slow and incremental. At the same time, homeowners who locked in 30-year mortgages at 3 percent rates between 2020 and 2022 are reluctant to sell and take on a new loan at today's rates, which are still above 6.5 percent as of September 2026. This dynamic, often called the rate lock-in effect, is keeping existing inventory thin across the county.

Mortgage Rate Environment

The Federal Reserve held rates steady through much of 2026, and the 30-year fixed mortgage rate has remained in the 6.4 to 6.8 percent range for most of the year. At those rates, a buyer financing $700,000 is looking at a monthly principal and interest payment of roughly $4,400 to $4,600, before property taxes. Nassau County property taxes are among the highest in the country, with effective tax rates often running between 1.5 and 2.5 percent of assessed value depending on the municipality. That means total monthly housing costs for a median-priced home can easily exceed $7,000 to $8,000 per month for a buyer with a standard down payment.

Demand from New York City Commuters

Nassau County's Long Island Rail Road network connects directly to Penn Station and Atlantic Terminal in Brooklyn, making it a practical choice for households with Manhattan or Brooklyn-based employment. The LIRR's Main Line, Port Washington Branch, Far Rockaway Branch, and Long Beach Branch all run through Nassau County communities, with peak-hour trains running frequently enough for daily commuting. That commuter connectivity keeps a steady pipeline of buyers from the city looking at Nassau County as an alternative to Brooklyn or Queens, where comparable home sizes would cost significantly more.

4. What These Prices Mean for Buyers in September 2026

Buyers entering Nassau County right now are navigating a market that rewards preparation and speed. Well-priced homes in desirable communities still attract multiple offers within days of listing. Understanding what your budget actually buys at current price levels is the first step to moving efficiently.

Budgeting Realistically for Nassau County

With a county median around $860,000 to $880,000, buyers should budget for down payments, closing costs, and property tax escrow from day one. Closing costs in New York typically run 2 to 5 percent of the purchase price, which on an $880,000 home means $17,600 to $44,000 in addition to the down payment. Buyers using conventional financing with 20 percent down on an $880,000 purchase would need $176,000 for the down payment alone, plus closing costs. First-time buyers should also ask their agent about the Nassau County Home Ownership Assistance Program and any applicable state-level programs through SONYMA, the State of New York Mortgage Agency.

Property Types and What You Get at Each Price Point

The Nassau County housing stock is overwhelmingly postwar construction, with the bulk of single-family homes built between 1945 and 1975. In the $500,000 to $700,000 range, buyers typically find cape cods and ranches with 3 bedrooms, 1 to 2 bathrooms, and lots of approximately 5,000 to 7,500 square feet in communities like Valley Stream, Elmont, or Westbury. In the $750,000 to $1 million range, split-levels and expanded capes with 4 bedrooms and updated kitchens become available in communities like Rockville Centre, Merrick, and Plainview. Above $1 million, colonial and tudor-style homes with formal dining rooms, 2-car garages, and lots over 10,000 square feet appear in communities like Garden City, Manhasset, and the Great Neck villages.

5. What These Prices Mean for Sellers in September 2026

Nassau County sellers are in a structurally advantageous position in September 2026, but that does not mean every listing succeeds. Overpriced homes still sit. Buyers are more financially stretched than they were in 2021, and they are paying closer attention to condition, taxes, and value. Sellers who price accurately and present their homes well are still seeing strong results.

Is Now a Good Time to List

September is historically an active month in Nassau County real estate, sitting just after the summer slowdown and before the late-fall pullback. Buyers who paused their search over July and August often re-engage in September with renewed urgency, particularly those hoping to close before the holiday season. Inventory tends to be lower than spring, which can work in a seller's favor. If you have been considering listing, September 2026 offers a window where demand is present and competition from other sellers is relatively contained.

Pricing Your Home Correctly in This Market

The gap between list price and sale price in Nassau County has narrowed compared to the frenzied market of 2021 and 2022, but well-priced homes are still closing at or above asking. The key is grounding the list price in recent comparable sales, not in what a neighbor sold for 18 months ago. A comparative market analysis from a local agent who tracks closed sales in your specific village or hamlet is essential. County-wide averages are useful for context, but your price should be set based on homes within a half-mile to one-mile radius that closed within the last 90 days.
