For twenty years, most Merrick sellers signed almost nothing before contract. Their attorneys handed the buyer a $500 credit at closing, and the Property Condition Disclosure Statement stayed blank in a drawer. That habit ended on March 20, 2024, and the Merrick market has spent the year since absorbing what it means.
The change looks technical on paper. In practice it moved the point of maximum negotiating pressure from post-inspection back to pre-contract, and Merrick's mid-century housing stock plus its South Shore geography give the amended form more to work with than in most Nassau towns.
The Merrick thesis for 2026: friction that used to appear at inspection now appears before the contract is even drafted, and Merrick sellers who prepare for that shift keep leverage that sellers who ignore it hand to the buyer's attorney.
What Actually Changed On March 20, 2024
The state's amended Property Condition Disclosure Act did three things at once. It removed the $500 credit option that downstate seller attorneys had defaulted to for two decades. It expanded the form from 48 questions to 56. And it added a full section on flood history and flood insurance drawn from FEMA's current maps.
The elimination of the credit is the headline. The amended PCDS took effect on March 20, 2024, includes language requiring the disclosure of issues related to flooding and removed the $500 credit if sellers fail or refuse to provide the PCDS, and sellers no longer have the option of providing the $500 credit in lieu of the PCDS. This is a significant change in real estate transactions, particularly in downstate New York where almost no seller ever provides the PCDS.
Behind that shift is a piece of case law most sellers have never heard of. Completion of the Disclosure provides a document that can be used against the seller in a suit under a common law theory such as one alleging fraud or negligent misrepresentation; the Disclosure is certified by the seller giving it certain evidentiary value, and by completing the Disclosure the seller may be giving the purchaser an advantage in subsequent litigation. That reasoning is why, mainly in downstate New York, seller's attorneys long recommended their seller-clients not complete or deliver the PCDS and simply opt to provide the purchaser with the $500 credit. The workaround is gone. The certification stays with the file.
The flood section is where the form got Merrick-specific. Property sellers are now obligated to disclose whether the property is in a FEMA-designated 100-year or 500-year floodplain, whether it is obligated to comply with federal flood insurance requirements, and if the property has any history of procurement of flood insurance. Sellers north of Merrick Road answer those questions with mostly clean records. Sellers in South Merrick near the canals answer them with paperwork trails that a buyer's attorney will read closely during the standard New York attorney review window.
The Timing Shift That Matters
The Merrick sale timeline has not changed. Correctly priced Nassau County homes in desirable school districts are routinely going into contract within one to three weeks of listing in 2026, and the full transaction timeline from accepted offer through attorney review, inspection, mortgage commitment, and closing typically runs 60 to 90 days in Nassau County, longer than many other markets due to the attorney review process and the volume of steps involved in a Long Island closing.
What changed is where the friction lives inside that 60 to 90 days. Before the amendment, a Merrick seller could stay quiet until the buyer's inspector wrote up the report, then negotiate credits against specific findings. After the amendment, the seller has already answered 56 written questions before the buyer's attorney signs anything. Those answers, and the "unknown" boxes checked next to them, set the tone for every credit discussion that follows.
The market backdrop makes that tone-setting more consequential. Merrick homes have been transacting at strong prices with a shrinking margin for surprise. Nassau County's single-family median closed sale reached $890,000 in May 2026, up 9.9% from $810,000 a year earlier, according to OneKey MLS. Merrick's own snapshot in June 2026 showed a median list around $969,000 at roughly $492 per square foot with median days on market near 33. A well-prepped Merrick listing still commands leverage. A listing with disclosure ambiguity forfeits some of that leverage before the first showing.
Old Oil Tanks, New Documentation Demands
Merrick's housing stock includes a substantial share of homes built between the 1940s and the 1960s, when heating oil was standard. Many of those homes have since converted to gas. What sits underground varies. The question the amended PCDS forces is whether the seller can prove the story.
When you convert to gas heat in your home, besides removing the old oil burner and boiler, you must also give thought to how you're going to decommission your old oil tank that may be buried beneath the ground. It's not just a recommendation, it's the law. Even if your oil tank was emptied and the fill pipes were plugged before the conversion, it's likely there remains a little oil or sludge, and over time the tank will start to decompose and what's left on the inside will leak out.
Nassau County keeps the paper trail. When abandonment is done properly, the homeowner receives a certificate, and in Nassau County the Department of Health also gets a certificate that is kept on file. That single document is what separates a smooth Merrick closing from a stalled one. Two things happen when a seller cannot produce it:
- The lender's underwriting slows or stops. Most mortgage companies will never approve a mortgage on a home with a buried oil tank, and more and more insurance companies are unwilling to issue homeowner's insurance policies for properties that have an underground oil tank.
- The buyer's inspector finds the physical tells. Capped fill pipes, abandoned copper lines, or a random-looking pipe near the foundation all count as evidence a tank exists. Once evidence surfaces without a certificate, negotiations pivot from price to remediation, and remediation opens the door to soil testing.
Long Island contractors including Domino's Oil Tank Service and GreenSeal Oil Tank Service perform abandonment and removal under NYSDEC procedures. The right time to pull the certificate, or to arrange abandonment, is before the listing photos go up. Waiting until the buyer's inspector asks the question moves the conversation to the buyer's timeline and the buyer's price.
Cesspools, Sewers, And The Grant Nobody Mentions
Most of Merrick sits on public sewer, which resolves the wastewater question quickly. Pockets on private systems still exist, and a seller who assumes without checking loses the same way the tank-uncertain seller loses.
Two facts matter here. First, the New York State Department of Environmental Conservation has determined that conventional septic systems and cesspools on Long Island are considered failing since they are neither designed, nor capable of removing significant amounts of nitrogen. That definition is a paperwork problem before it is an engineering problem. Second, Nassau County offers real money to fix it. The Septic Environmental Program to Improve Cleanliness, administered by the Nassau County Soil and Water Conservation District, provides grant funding of up to $20,000 to eligible homeowners, not-for-profits, and small businesses to replace conventional septic systems and cesspools with nitrogen-reducing innovative and alternative onsite wastewater treatment systems. Launched in May of 2021, the S.E.P.T.I.C. program is administered by the Nassau County Soil and Water Conservation District on behalf of Nassau County, has been awarded over $8 million to fund approximately 400 upgrades, of which 186 had been installed as of July 30, 2025.
The strategic point for a Merrick seller is not the grant amount. It is that a buyer's attorney who sees an unresolved cesspool question on the PCDS knows the grant exists too, and can price the eventual replacement into their credit request whether or not the seller ever applies.
What A Prepared Merrick Listing Looks Like Now
The pre-list checklist has quietly grown. It is no longer enough to stage the living room and price against last month's comps. A Merrick seller preparing to answer 56 questions in writing works from a different list:
- Pull the Nassau County Department of Health tank abandonment certificate, or confirm in writing that no underground tank ever existed on the parcel.
- Locate any prior flood insurance policy declarations, FEMA elevation certificate, and record of past claims. South Merrick sellers in particular should map their parcel against FEMA's current flood insurance rate maps before the PCDS is drafted.
- Confirm sewer connection status through Nassau County tax records. If the property is on cesspool or septic, decide whether S.E.P.T.I.C. grant work happens before listing or gets disclosed as-is.
- Gather permits and certificates of occupancy for finished basements, extensions, and any renovation that touched load-bearing walls. Merrick's Cape and expanded ranch stock is full of legal-but-undocumented work.
- Reconcile the Nassau County property tax assessment with any prior grievance history. Nassau County property taxes are among the highest in the nation, buyers will factor this into their monthly payment calculations immediately, and knowing tax grievance history, STAR exemption status, and tax class designation gives your agent the tools to address objections before they kill a deal.
Every item on that list either closes a PCDS question with a document or gives the listing agent something concrete to say when the buyer's attorney raises it. That is what pre-contract leverage looks like in Merrick right now.
FAQ
Does the amended PCDS apply to co-ops or condos in Merrick? No. Residential real estate under the law means a 1-4 family dwelling used or intended to be used as a residence; unimproved land, condos, coops and HOA sales are not covered.
What if the property is being sold from an estate? The sale of a residence by the estate of a deceased owner is exempted from the delivery of a PCDS. That exemption does not eliminate common-law disclosure obligations, and it does not help the executor if a buried tank surfaces after closing.
Can a seller answer "unknown" to most questions? Legally, yes. The property disclosure must be based on the seller's actual knowledge, without imposing an affirmative duty to investigate the property. Practically, a Merrick PCDS full of "unknown" answers signals to the buyer's attorney that the seller either did not prepare or is hiding something. Either read costs the seller money during attorney review.
Does the mansion tax affect a Merrick sale? Above $1 million, yes. If your sale price exceeds $1 million, an additional mansion tax applies, and though this is technically paid by the buyer, it often enters negotiations. With Merrick's median list running near $969,000 in mid-2026, a growing share of Merrick sales cross that threshold, and it becomes another line item the buyer's attorney weighs against every open PCDS answer.
