"Building Up, Pricing Out: How Long Island's New Developments Are Pushing Property Values into the Stratosphere"

If you're waiting for Long Island home prices to "cool off," you might want to grab a beach chair—this is going to take a while. June 2025 just dropped its latest housing market data, and spoiler alert: unless you’ve got a secret inheritance or a side hustle that prints money, you're going to feel it.

The Numbers Don't Lie (But They Do Laugh at Your 2020 Zillow Estimates)

According to the most recent stats, the median sales price jumped to $958,000, up a shocking 17% from June 2024. The average sale price nudged up to $921,400, a 2% increase. On the flip side, the number of days homes sit on the market dropped from 48 to 36, meaning buyers are swiping right fast.

Translation? Long Island real estate is not just holding—it’s flexing.

The Inventory Squeeze: Fewer Homes, More Elbows

We’re down to 39 active listings, down 22% year-over-year, while sold listings more than tripled (from 7 to 25). That’s like showing up to a buffet only to find three mini bagels and a slice of lox—and fifteen people already in line.

So what’s driving all this madness? In one word: development. In five more: "Shiny new homes and amenities."

New Builds, Old Problems... with a Modern Price Tag

From Merrick to the outskirts of Suffolk County, new developments are springing up like someone whispered “school district” and “walkable” in the same sentence. And these aren’t your average vinyl-sided, builder-grade ranches. We're talking modern floor plans, smart-home tech, EV charger-ready garages—the works.

But every new neighborhood means a bump in value across the board. It also means older homes nearby suddenly look like "fixer-uppers" even if they were totally fine a year ago. That’s gentrification, baby—Long Island style.

Sellers, Don’t Get Cocky. Buyers, Don’t Blink.

Sure, sellers are riding the high of a 102.1% sale-to-list ratio, but that doesn’t mean you can skip landscaping or leave your outdated backsplash unaddressed. Buyers are still picky—and now they have VR tours to pick you apart before they even walk in.

Buyers, meanwhile, need to be armed with more than just pre-approvals. Try prayer, caffeine, and a very patient agent. The average mortgage rate dipped to 6.01%, which isn’t low, but it’s at least better than the trauma-inducing 7+% we saw not long ago.

Market Dynamics at Play: It’s Not Just About the Homes

This surge isn’t happening in a vacuum. Improved infrastructure, zoning adjustments (gasp—yes, some towns are finally cooperating), and post-COVID lifestyle shifts are fueling this growth. People want space, community, and less grind—but they’re still willing to pay top dollar to stay close to the LIRR, good schools, or even just a halfway-decent deli.

Top Tier Takes: Merrick’s Million-Dollar Moment

Check out Merrick's top 10 sales from June—all over a million, with the highest ringing in at $1.29M. These homes aren't just well-located—they’re Instagram-ready, move-in ready, and clearly priced like someone might be ready to sell if the price is just right.

Bottom Line: Buy, Sell, or Watch From the Sidelines, This Market Has a Mind of Its Own

You can’t predict the market, but you can understand the trends—and right now, the trend is up. Developments are attracting new buyers, pushing prices higher, and squeezing inventory tighter than parking at Jones Beach on the Fourth of July.

CTA: Thinking about selling before another shiny new neighborhood shows up next door? Or buying before prices leap another 17%? Call Dean Miller—because Zillow doesn’t negotiate, and your cousin from Queens isn’t a real estate expert just because he watched five episodes of Selling Sunset.

Let’s figure out your next move… before Long Island makes it for you.
