For almost a decade, Long Island homeowners have benefited from an incredibly tight, low-inventory housing market. Buyers outnumbered available homes, leading to bidding wars, over-asking offers, waived contingencies, and record-high sale prices. But in late 2024 and throughout 2025, something began shifting beneath the surface — and the effects are becoming clearer every month.

Inventory is rising again.
Not dramatically. Not in a way that crashes prices. But enough to meaningfully change the psychology of buyers, the strategies sellers must use, and the kind of results homeowners can expect over the next 6–12 months.

As we approach the end of 2025 and head toward the 2026 market cycle, Long Island is officially transitioning away from the extreme seller’s market we’ve known… into something more balanced, more competitive, and more sensitive to pricing.

This article breaks down what the inventory surge means, why it’s happening, and what homeowners should do before conditions shift again.

1. Yes — Inventory Is Rising. Here’s What That Means.

For years, Long Island’s biggest market issue was the same:
there simply weren’t enough homes for sale.

In 2023–2024, Nassau and Suffolk County inventory sat between 1.5–2 months of supply — historically low and far below the 5–6 months that define a balanced market.

But 2025 has changed the story.

More homeowners are listing
Fewer buyers are rushing to overpay
Mortgage rates aren’t dropping as hoped
Days on market (DOM) are slowly increasing
Price reductions are returning
Buyers have more choices than they’ve had in years

Put simply:
When inventory rises, buyers gain leverage — and sellers have to work harder.

2. Why Inventory Is Rising Right Now

There are several reasons inventory has begun to grow again, especially across Long Island:

A) “Rate Lock” Is Fading

From 2021–2023, homeowners with 2.5%–3.5% mortgages refused to move. Many still don’t want to lose their low-rate loan, but life events are happening anyway:

growing families
downsizing
job relocations
inheriting property
divorce
needing to unlock equity

Homeowners who “waited” are finally listing — adding supply.

B) Mortgage Rates Aren’t Falling As Low As Expected

Buyers had been waiting for rates to drop into the 4’s.
Instead, they’re holding closer to the mid-6s.

This “rate disappointment” is:

keeping some buyers cautious
reducing bidding-war intensity
increasing the time buyers take before making an offer

When buyers move slower, inventory grows.

C) Local Investor Activity Is Cooling

Long Island investors are more selective today because:

cash flow is tighter
prices are high
competition has cooled
regulations are unpredictable
insurance costs are rising

Investors once scooped up every fixer-upper — now they’re being picky.

That leaves more inventory on the market.

D) Baby Boomers Are Selling

Older Long Island homeowners are cashing out in growing numbers:

moving south
downsizing
settling estates
avoiding rising taxes

Boomers held onto homes for a long time, but that trend has reversed.

E) New York City Ripple Effects

Political changes in Manhattan — including fear around rent policies, tax shifts, and new leadership — have some NYC owners selling early or relocating to the suburbs.

As NYC supply rises, some buyers who would’ve fled to Long Island are re-evaluating.

This adds to our inventory.

3. What Rising Inventory Means for Home Values in 2025–2026

Rising inventory does not mean a crash is coming.

But it does mean the days of:

20 offers
$100,000 over asking
no contingencies
homes selling in 48 hours

…are fading.

Here’s what homeowners should expect:

A) Prices Are Stabilizing, Not Dropping

Long Island demand is still strong.
Inventory is rising — but from historically low levels.

So instead of falling, prices are:

flattening out.

Not skyrocketing.
Not declining sharply.
Just stabilizing.

For most homeowners, that means your home’s value is near its peak, but appreciation has slowed down.

B) Buyers Are Becoming More Selective

When buyers have options, they behave differently:

They wait.
They negotiate harder.
They inspect everything.
They ask for concessions.
They skip homes needing work.

In 2021, even a dated home would sell instantly.
In 2025, condition matters again.

C) As-Is Homes Are Losing the Most Leverage

This is one of the biggest shifts in the 2025 market.

Homes that are:

outdated
cluttered
in probate
needing repairs
tenant-occupied
poorly maintained

…are staying on the market significantly longer than move-in-ready homes.

When buyers have more choices, they avoid headaches.

This is hugely important for homeowners who:

inherited a property
are overwhelmed
can’t afford repairs
need to sell fast
want a predictable closing

These sellers must price more strategically than in past years.

D) Price Reductions Are Becoming Normal Again

Reducing price felt taboo from 2021–2023.

But with rising inventory, price reductions are returning — not because sellers are desperate, but because the market is normalizing.

Expect:

more listings adjusting their price after 2–3 weeks
buyers sending lower offers
fewer waived contingencies
higher negotiation pressure

In a rising-inventory market, you must price with the market, not against it.

4. The Big Question: Should You Sell Now or Wait Until Spring 2026?

Homeowners always ask:

“Should I list now — or wait for the spring market?”

This year, the answer is different.

For many years, waiting for spring was the best move.

But in a rising-inventory environment?

Waiting could mean more competition.

Here’s why:

A) More Homes Hit the Market in Spring

Spring 2026 will have:

more listings
more price competition
more inventory pressure
more choices for buyers

If you list now, you’re ahead of that wave.

B) Winter Buyers Are More Serious

Winter buyers are:

motivated
job relocating
family planning
serious about finding a home

There may be fewer buyers, but the ones shopping are real.

C) Prices Are Strong Right Now

Values are stable — and near all-time highs.

But if inventory continues rising into 2026, price stabilization could turn into price softening.

Selling sooner removes that risk.

D) Market Psychology Is Changing

Buyers in 2021–2022 had FOMO.
Buyers in 2025 have options.

That’s a major shift.

Waiting may mean:

more negotiation
longer days on market
more concessions
tougher inspections

Selling now avoids the peak competition cycle.

5. How the Inventory Surge Affects Nassau vs Suffolk

Inventory isn’t rising evenly across Long Island.

Here’s a more localized breakdown:

Nassau County

Faster-paced
Higher-priced
Lower days on market
Limited new construction
Buyer demand still very strong

Inventory is rising, but Nassau remains extremely competitive in:

Garden City
Rockville Centre
Merrick
Massapequa
Mineola
Floral Park

Older homes needing updates are the segment slowing down.

Suffolk County

Suffolk inventory is rising faster because:

more land
more listings
more estate sales
more aging homes
more sellers relocating south

Areas seeing the largest inventory growth include:

Islip
Brookhaven
Smithtown
Riverhead

Move-in-ready homes still sell quickly, but anything needing work faces new competition.

6. What Homeowners Should Do Right Now

If you’re thinking about selling in the next 6–12 months, the rising inventory trend is extremely important.

Here’s what smart homeowners should do now:

A) Get a Professional Price Analysis (Not Just a Zestimate)

In a rising-inventory environment, you must:

price accurately
avoid overpricing
attract early activity

Overpricing kills momentum in today’s market.

B) Improve What You Can — Don’t Renovate Everything

Buyers in 2025 prefer move-in-ready homes.
But homeowners shouldn’t overspend.

The biggest ROI improvements right now are:

paint
flooring
lighting
landscaping
decluttering

Not major kitchens.
Not full bathrooms.
Not large renovations.

C) Consider Selling As-Is If You’re Overwhelmed

For homeowners dealing with:

inherited property
probate
relocation
divorce
major repairs
too many belongings

Selling as-is in today’s market can still be successful — but pricing strategy matters 10x more than in 2021–2023.

D) Pre-Inspection Can Save You Money

With buyers negotiating harder, a pre-inspection:

reduces surprises
prevents buyer panic
helps set realistic expectations
protects your net

This is especially helpful with older homes.

E) Time Your Listing Strategically

The best weeks to list heading into winter are:

Week before Thanksgiving (motivated buyers)
First two weeks of December (surprising strong demand)
January 2nd–15th (new-year relocations)

The worst weeks for fresh listings are:

Christmas Week
Last week of December

7. Predictions Going into 2026

Based on the current data and trends, here’s what’s most likely in 2026:

A) Inventory Will Continue Rising Slowly

Not a flood — but steady growth.

Each quarter = more listings than last year.

B) Prices Will Level Off

Expect slight fluctuations depending on town and condition:

Move-in-ready homes → still strong
Outdated homes → more price pressure
Luxury homes → softer demand
Fixer-uppers → more negotiation
Estates & probates → longer timelines

C) Days on Market Will Increase

What once sold in 3 days may take:

14 days
21 days
even 30–40 days

This is normal.
This is healthy.
This is a real estate cycle returning to balance.

D) Buyers Will Regain Confidence

As inventory grows, buyers:

feel less urgency
get more negotiating power
worry less about missing out
take longer to choose

This doesn’t crash prices — it normalizes them.

E) Sellers Must Be More Strategic Than Before

2021 required no strategy.
2025–2026 requires:

pricing skill
marketing
preparation
timing
negotiation expertise

The good news is:
Long Island is still one of the strongest, most stable markets in the country.

Values remain high.
Demand remains strong.
Inventory remains relatively tight.

But the days of “list it and watch the frenzy” are over — and being strategic is the difference between getting an average result and maximizing your sale.

8. Final Thoughts: What This Means for You as a Long Island Homeowner

The real estate market is changing — not crashing.

Inventory is rising — not exploding.

Prices are stabilizing — not collapsing.

But these shifts matter, because psychology drives real estate, and when buyers gain options, sellers must gain strategy.

If you’re planning to sell in the next:

3 months
6 months
12 months

…these inventory trends will directly impact your pricing power and your final sale result.

The best thing you can do is get clarity now.
