Long Island Real Estate Market Update: June 2026

Inventory is rising slightly, prices are still climbing, and homes across Nassau and Suffolk counties continue to sell above asking price. Here is what the numbers mean for you this summer.

Where the Long Island Market Stands This June

Every June brings a moment to step back and take stock of where the Long Island real estate market actually is, not where headlines say it should be, but where the data says it is. As we move into the heart of summer 2026, the story is one of persistent strength. Prices are up across both Nassau and Suffolk counties, homes are still selling above asking price, and closed sales are outpacing last year's totals. If you were expecting the market to have cooled into something more balanced by now, the numbers tell a different story.

That said, there are genuine shifts worth paying attention to. New listings are trickling in at a modestly higher rate than a year ago, and the inventory decline that defined 2023 and 2024 has not reversed, but it has begun to stabilize in Nassau. Suffolk is still seeing a meaningful year-over-year drop in available homes, which is keeping upward pressure on prices in that county. Across Long Island as a whole, buyers are still competing for a limited pool of single-family homes, and the market reflects that reality in both the sale-to-list ratios and the pace at which homes are moving.

As a Long Island real estate agent working in this market every day, I want to give you a clear, honest picture of what these numbers mean whether you are thinking about selling, actively searching for a home, or simply keeping an eye on the market. Let's walk through the data county by county and then put it all together.

Nassau County Housing Market: June 2026

Nassau County's single-family market in June 2026 reflects a market that has found a kind of disciplined rhythm. The median sale price has climbed to $875,000, a 2.9 percent increase compared to June 2025. That is a measured, sustainable rate of appreciation rather than the sharp double-digit jumps that characterized earlier years in this cycle. Closed sales came in at 743, up 1.5 percent year-over-year, which tells us that despite affordability pressures, transactions are still completing at a healthy rate. New listings rose 5 percent to 1,241, a meaningful uptick that hints at more sellers finding the confidence or the motivation to come to market this summer.

Two figures stand out in Nassau County's June report. First, the days on market has held steady at 42 days with no change from a year ago. That stability suggests the market has settled into a pace that both sellers and buyers have largely come to expect. Homes priced correctly are not sitting, and homes priced aggressively are not flying off the shelf in days either. It is a more deliberate market than 2022, but it is far from slow. Second, the sale-to-list ratio of 101.3 percent is a concrete reminder that buyers are still paying above asking price on average. That number does not happen in a soft market. It happens when demand is outrunning available supply, which is exactly what a 5.5 percent year-over-year decline in available homes confirms.

The slight increase in new listings is an encouraging sign for buyers who have been waiting for more options. However, with available inventory still declining and the sale-to-list ratio firmly above 100 percent, Nassau County remains a seller's market in June 2026. More listings are entering the pipeline, but they are being absorbed by demand before they can meaningfully shift the balance of power at the negotiating table.

Suffolk County Housing Market: June 2026

Suffolk County is posting some of the more striking numbers on Long Island this month. The median sale price reached $750,000 in June 2026, representing a 7.1 percent increase year-over-year. That is more than double Nassau's rate of appreciation, which reflects how much of the demand pressure in Suffolk has compressed into a market where available inventory has declined sharply. Closed sales of 963 are up 3.7 percent from a year ago, and new listings of 1,507 have barely budged, rising just 0.1 percent year-over-year. The gap between the slight increase in new listings and the volume of buyers actively pursuing homes in Suffolk is what is driving that strong price appreciation.

Suffolk's sale-to-list ratio of 101.8 percent is actually higher than Nassau's this month, which underscores the competitive nature of the market across the county's broader geography. When available inventory has dropped 11.6 percent year-over-year and new listings are essentially flat, there is simply not enough supply to ease the competitive dynamic that pushes final sale prices past asking. Days on market at 44 is close to Nassau's pace, confirming that well-positioned homes across Long Island are moving at a similar rhythm regardless of which county they sit in.

The 7.1 percent price appreciation figure in Suffolk deserves context. It is not a sign of a market running out of control. It is a direct mathematical response to the supply and demand imbalance reflected in the inventory data. Until new listing activity accelerates meaningfully in Suffolk County, buyers should expect to continue facing competitive conditions, and sellers should understand that the market is working in their favor right now more than the headline numbers might suggest.

The Long Island Single-Family Market at a Glance

When you combine Nassau and Suffolk counties, the picture of the Long Island single-family market in June 2026 comes into sharper focus. Across the island, there were approximately 5,311 single-family homes available, a decline of roughly 8.6 percent compared to June 2025. Total closed sales came in at approximately 1,706 transactions for the month, and new listings added up to roughly 2,748 across both counties. These figures represent a market that is active and moving, but one where the foundation of tight supply has not been disrupted.

The combined inventory decline of 8.6 percent year-over-year is one of the most important numbers in this entire report. New listings are up marginally when you combine both counties, but they are not accumulating into inventory because demand is absorbing them. Homes are closing, buyers are active, and the gap between available supply and buyer interest remains wide enough to keep both sale-to-list ratios above 100 percent in each county. For Long Island as a regional housing market, June 2026 reads as a continuation of the seller-favored conditions that have defined this market for the better part of three years.

Buyer Demand Remains Active

One of the questions I hear most often right now is whether buyer demand has softened in the face of interest rates and affordability challenges. The closed sales data for June 2026 gives the clearest possible answer: no, it has not. Nassau County closed 743 single-family sales, up 1.5 percent from a year ago. Suffolk closed 963, up 3.7 percent. These are not the numbers of a market where buyers have stepped to the sidelines. These are the numbers of a market where buyers are competing, adjusting their budgets, leaning on various financing strategies, and ultimately completing transactions.

The sale-to-list ratios in both counties reinforce this point. A ratio of 101.3 percent in Nassau and 101.8 percent in Suffolk means that the average home on Long Island is selling for more than what the seller originally asked. That does not happen without motivated, competing buyers in the room. While individual neighborhoods and specific price points will always have their own dynamics, the county-level data for June 2026 shows demand that is not only present but capable of pushing prices past asking. That is meaningful context for anyone trying to understand where this market truly stands heading into the second half of 2026.

Single-Family Homes Are Not the Entire Story

The data presented in this report focuses on single-family homes, which represent the largest and most closely watched segment of the Long Island housing market. But it is worth acknowledging that condominiums and co-operatives represent a significant portion of the total housing stock across Nassau and Suffolk counties, particularly in more densely developed communities and along major corridors. The OneKey MLS June 2026 data referenced here covers single-family residential properties, so the specific figures for condos and co-ops fall outside the scope of this particular report.

What I can say from experience in this market is that the same supply and demand dynamics affecting single-family homes generally create ripple effects across attached housing as well. When single-family inventory is tight and prices are rising, buyers who may have originally targeted a single-family home often expand their search to include condominiums and co-ops, which puts additional competitive pressure on those segments too. If you are specifically interested in the condo or co-op market in a particular Nassau or Suffolk community, reach out directly and I can pull the relevant data for your search.

What the June 2026 Market Means for Long Island Sellers

Pricing Strategy Matters More Than Ever

The sale-to-list ratios of 101.3 percent in Nassau and 101.8 percent in Suffolk are encouraging, but they come with an important caveat: those averages reflect homes that were priced correctly from the start. Homes that come to market overpriced are sitting longer and often ending up with price reductions that attract less competitive offers. The 42-to-44-day average days on market suggests buyers are thoughtful and doing their research. Pricing your home at a level that reflects current comparable sales, not wishful thinking, is still the single most important decision you will make as a seller in this market.

Inventory Is Still Working in Your Favor

With available single-family inventory down 5.5 percent in Nassau and 11.6 percent in Suffolk year-over-year, the competitive environment that benefits sellers has not evaporated. Buyers are still looking at a relatively limited pool of homes, which means a well-prepared, properly priced listing is likely to attract genuine interest. If you have been waiting for the right window to sell, the June 2026 data suggests that window is open. Inventory levels this low historically correlate with seller-favorable negotiating dynamics, and both counties are displaying those characteristics right now.

Preparation and Presentation Still Drive Results

Even in a market where homes are selling above asking price on average, presentation matters. Buyers who are spending $750,000 or $875,000 or more have high expectations, and they have access to every listing on the market through their phones. Homes that are well-staged, professionally photographed, and move-in ready consistently outperform homes that are not. The days on market figure of 42 to 44 days reflects an average that includes homes that needed price corrections. Sellers who invest in proper preparation tend to see faster, stronger results, and in this market, that combination of speed and price is absolutely attainable.

More Competition Is Coming to Market

The 5 percent increase in new listings in Nassau County is a signal worth noting. It does not represent a flood of new inventory, but it does suggest that more sellers are coming off the sidelines. If that trend accelerates into the second half of 2026, buyers will have incrementally more choices, which could moderate some of the competitive pressure that has benefited sellers. This is not a reason to panic, but it is a reason to move with some urgency if you are planning to list. The market conditions of June 2026 are favorable, and waiting too long to list always carries the risk of entering a slightly more competitive seller environment.

What the June 2026 Market Means for Long Island Buyers

Competition Is Real but Not Insurmountable

The sale-to-list ratios and inventory declines in this report confirm that buyers are operating in a genuinely competitive environment. But competitive does not mean impossible. Buyers who are pre-approved, working with an experienced local agent, and prepared to move decisively on the right home are still closing transactions every month across Long Island. The 1,706 combined closed sales in June 2026 represent 1,706 buyers who succeeded in this market. The key is having a clear strategy, a realistic budget, and the professional support to execute quickly when the right property becomes available.

Know Your Numbers Before You Start

In a market where homes regularly sell above asking price, buyers who have not been pre-approved or who have not clearly defined their maximum budget are at a structural disadvantage. When competing offers are involved, the ability to respond within hours rather than days is often the difference between getting the home and losing it. Getting fully pre-approved, understanding your ceiling, and having a conversation with your agent about realistic offer strategies before you tour your first home are not optional steps in this market. They are the foundation of a successful search.

Patience and Selectivity Are Assets

The days on market of 42 to 44 days tells us that not every home sells in the first week. Some listings sit, either because they are priced too high, need work, or simply have not found their right match yet. Buyers who stay patient, keep their search criteria focused, and avoid the trap of making emotional overbids on properties that do not truly fit their needs tend to find better outcomes. There will be homes in this market that attract fierce competition, and there will be homes that have been sitting for three or four weeks where a well-crafted offer has room to negotiate. Knowing the difference is where a knowledgeable local agent adds real value.

Expanding Your Geographic Search Can Open Doors

Long Island is not one uniform market. It is a collection of distinct communities, each with its own price points, inventory levels, and competitive dynamics. Suffolk County's median sale price of $750,000 is meaningfully lower than Nassau's $875,000, and within each county there is significant variation from community to community. Buyers who are flexible about their target geography, while still staying within commuting or lifestyle parameters that make sense for their lives, often find that expanding their search radius by even a few miles opens up meaningfully more options at a price point they can afford. A local agent who knows the nuances across multiple communities can be an invaluable guide in identifying where the best opportunities are right now.

Is Long Island Still a Seller's Market?

Based on the June 2026 data, the answer is yes. Both counties are showing declining available inventory year-over-year, sale-to-list ratios above 100 percent, rising median sale prices, and growing closed sales volumes. These four factors together constitute the defining characteristics of a seller's market, and all four are present across Nassau and Suffolk this month. There are signs that the extreme imbalance of 2022 has moderated into something more functional, with days on market stabilizing and the rate of price growth in Nassau sitting at a measured 2.9 percent. But moderation is not reversal. Long Island sellers still hold significant leverage in June 2026, and buyers are operating in an environment that requires preparation, realism, and professional guidance to navigate successfully.

Whether that balance shifts further toward buyers in the second half of 2026 will depend largely on how inventory trends evolve. If new listings continue to edge higher and the absorption rate slows even slightly, conditions could gradually become more balanced. But based on what the data shows right now, Long Island remains a seller's market, and the numbers support that conclusion clearly.

Frequently Asked Questions

What is the median home price on Long Island in June 2026?

Based on OneKey MLS data for June 2026, the median sale price for single-family homes in Nassau County is $875,000, up 2.9 percent year-over-year. In Suffolk County, the median sale price is $750,000, up 7.1 percent year-over-year. These figures reflect single-family residential transactions and do not include condominiums or co-operative apartments.

How long are homes sitting on the market on Long Island right now?

In June 2026, the average days on market for single-family homes is 42 days in Nassau County and 44 days in Suffolk County. Nassau's figure is unchanged from a year ago, indicating a stable and consistent pace for the market. Homes that are priced accurately and well-prepared tend to move faster than the average, while overpriced or unprepared listings account for much of the upper end of that range.

Are homes selling above asking price on Long Island?

Yes. The sale-to-list price ratio is 101.3 percent in Nassau County and 101.8 percent in Suffolk County as of June 2026. This means the average single-family home is selling for more than its original list price. This is a direct reflection of the competitive supply and demand conditions present in both counties, where available inventory has declined year-over-year while closed sales volumes have increased.

Is now a good time to sell a home on Long Island?

The June 2026 market data points to conditions that favor sellers. Inventory is down year-over-year in both Nassau and Suffolk counties, homes are selling above asking price on average, and closed sales are up compared to June 2025. That combination represents genuine seller leverage in the market. As always, the best time to sell depends on your individual circumstances, timeline, and financial goals, and a conversation with a local agent can help you determine whether June or another point in 2026 makes the most sense for your situation.

Is Long Island's real estate market expected to slow down in 2026?

Based on the June 2026 data, there are no signs of a significant slowdown. Prices are rising, sales are up, and inventory remains below year-ago levels. Nassau County is showing a modest increase in new listings, which could incrementally improve conditions for buyers as the year progresses, but the structural supply shortage across Long Island has not resolved. Predicting market direction with certainty is always difficult, but the current indicators do not suggest the kind of correction that would substantially shift the market away from seller-favorable conditions in the near term.
