Your monthly look at Uniondale home prices, inventory and recent sales, using September 2026 data from Realtors Property Resource® (RPR) and a 12-month review of OneKey® MLS closed sales.
If you are buying or selling a home in Uniondale this fall, the September 2026 numbers point to a market that is still firmly tilted toward sellers. RPR classifies Uniondale as a seller’s market: there were just 2.22 months of inventory, the median sold price rose to $640,000, and the typical home closed at 102.6% of its list price. At the same time, the homes that closed in September had spent longer on the market than in August, so not every listing is moving at the same speed.
Uniondale is a small market, so a handful of sales can swing the monthly figures. That is why this report also includes a 12-month look at 85 closed sales alongside RPR’s monthly data. Below, we break down what the numbers mean for buyers and sellers and feature 20 recently sold homes from across Uniondale — including sales on Northern Parkway, Southern Parkway, Barry Place, Henry Street and Warwick Street.

What the September 2026 Numbers Mean for Uniondale
Home prices: a strong month and a steady 12-month trend
The median sold price in Uniondale was $640,000 in September, up 12.3% from August. With only 11 sales in the month, that jump partly reflects which homes happened to close, so it helps to look at the broader value picture as well. RPR’s median estimated property value for Uniondale stands at $662,450, up 2.1% month over month and up 4.2% over the past 12 months. That longer trend is usually a better gauge of where homeowner equity is heading than any single month of closings.

Inventory: very tight, and tighter than last month
Uniondale had 2.22 months of inventory in September, down 36.6% from the prior month and down 31.7% from a year earlier. In practical terms, if no new homes came to market, the current supply would sell out in a little over two months — well within the range generally associated with sellers holding the advantage. There were 20 active listings (down 28.6% month over month) with a median list price of $729.5K, and 12 new listings came to market during the month (down 7.7%) at a median list price of $745K.

Days on market: closed sales took longer, new contracts came faster
Homes that sold in September had a median of 64 days in RPR, up 88.2% from August. Earlier in the pipeline the picture is quicker: the full pending pool showed a median of 26 days (down 39.5%), and new pending listings went under contract in a median of 30 days (up 3.4%). Active listings showed a median of 36 days. In short, several of September’s closings had been on the market for a while, but homes going under contract now are moving at a brisker pace.

Price per square foot and home size
Sold homes closed at a median of $576 per square foot, up 27.4% month over month. Active listings are asking a median of $468 per square foot (down 6.8%) for a median of 1,600 square feet of living area, while new listings came in at $464 per square foot and a median of 1,552 square feet. The gap between sold and active price per foot is another sign that September’s small group of closings leaned toward homes that commanded strong prices for their size.

Sales activity and pending contracts
A total of 11 homes sold in September, up 57.1% from August, for a total dollar volume of $7.43 million (up 71%). Looking ahead, 14 new pending listings (up 16.7%) and 32 total pending listings (up 14.3%) suggest a healthy flow of closings in the coming weeks. The median list price of pending homes was $679K, up 3.3%. RPR’s public-records sales section did not have enough activity in Uniondale this month to report, so the figures above come from listing data.

| Sold | 11 (↑57.1%) | $640K sold (↑12.3%) | $576 (↑27.4%) | 64 (↑88.2%) | $7.43M (↑71%) |

Uniondale Closed Sales Snapshot (Nov 2025 – Oct 2026)
To smooth out the month-to-month swings in a small market, we also looked at 85 closed sales recorded in OneKey® MLS between November 3, 2025 and October 23, 2026. Over that 12-month period the median sold price was $688,000, with sales ranging from $450,000 to $1,257,000. Most of the activity sat in the middle of the market: 36 sales closed between $600,000 and $699,999 and 30 between $700,000 and $799,999. The median home closed at 101.3% of its original list price after a median of 34 days on market.
These 12-month figures differ from RPR’s September snapshot (for example, a $688,000 median versus $640,000) because they cover a full year of sales rather than a single month. Both are accurate for their own scope. For buyers, the 12-month data shows where most Uniondale homes actually trade; for sellers, it confirms that homes have consistently sold close to or above their asking prices over the past year.

What This Market Means for Uniondale Buyers
- Expect competition on well-priced homes. With sold homes closing at a median of 102.6% of list price in September, buyers should be prepared for offers at or above asking on the most appealing listings.
- Have financing ready before you shop. Only 20 homes were active in September and inventory fell 36.6% in a month, so a mortgage pre-approval helps you act quickly when the right home appears.
- Focus on the $600K–$799K range. Over the past 12 months, 66 of 85 Uniondale closings fell in this band, so that is where you will see the most choice and the most comparable sales.
- Review recent comparables before offering. Active listings carry a $729.5K median list price, above September’s $640,000 median sold price. Recent sales are the best guide to where a specific home is likely to trade.
What This Market Means for Uniondale Sellers
- Conditions favor sellers. RPR rates Uniondale a seller’s market, and just 2.22 months of supply keeps buyers competing for a small number of homes.
- Equity has grown. The median estimated value is $662,450, up 4.2% over the past 12 months. A current home valuation can show what that means for your property.
- Pricing still matters. September’s sold homes had a median of 64 days in RPR, up sharply from August. Homes priced in line with recent sales tend to go under contract faster.
- Low competition from other listings. With active listings down 28.6% month over month, a well-prepared home can stand out this season.
