Hear From Our Clients
Seaford’s 11783 ZIP code contains two fundamentally different real estate markets, and the spread between them can run into the hundreds of thousands of dollars. South Seaford’s canal-front streets along Seaford Creek and Island Creek come with private docks, FEMA flood zone designations, mandatory flood insurance, and direct access to South Oyster Bay. The inland neighborhoods north of Sunrise Highway are a different story entirely — post-WWII Cape Cods and raised ranches, quieter streets, and a buyer pool that’s largely driven by school district quality and LIRR commuter access.
If you’re selling in Seaford, getting that distinction right means the difference between a listing that moves in 17 days and one that sits. If you’re buying, it means understanding what you’re actually paying for — and what it’s going to cost you to own it year after year, flood insurance premiums included.
Working with us means you get honest pricing, not a blended median applied to a market that doesn’t work that way. It means your offer strategy reflects what’s actually happening on the specific street you’re targeting in Seaford, not just what Nassau County looked like last quarter. And it means when something comes up — an inspection issue, a flood zone disclosure, a permit question with the Town of Hempstead — you have someone who’s already seen it before.
Lisa Caputo Sells Long Island is a licensed Broker Associate and Certified Buyer Broker operating under Signature Premier Properties — Long Island’s fastest-growing independent real estate firm, with 20-plus offices across Nassau and Suffolk counties. I’ve been working the Nassau County market for over 15 years, full time. Not as a side project, not between other jobs — this is my career, and it shows in how I work.
I’m based in Bethpage, which sits directly north of Seaford on the Seaford-Oyster Bay Expressway. That’s not a coincidence — it’s the same corridor, the same market, and the same buyer pool I work with every day. I know what a canal-front home in South Seaford actually requires at the closing table, and I know what a family comparing the Seaford Union Free School District to Wantagh’s needs to hear to make a real decision.
My clients consistently describe the same experience: I pick up the phone, I tell the truth about pricing, and I don’t disappear after the contract is signed. That’s not a promise — it’s what the reviews say, repeatedly, in their own words.
Whether you’re buying or selling in Seaford, the first step is a real conversation — not a pitch. If you’re a homeowner thinking about listing, I’ll walk you through a complimentary comparative market evaluation that looks at what homes have actually sold for in Seaford, not just what’s currently listed. With median sale prices around $730,000 and year-over-year appreciation running at 8.5%, many Seaford homeowners haven’t looked at their equity in years. That conversation alone is worth the call.
If you’re buying in Seaford, the process starts with understanding exactly what you’re looking for and where in Seaford you’re looking for it. North of Sunrise Highway or south of it matters — a lot. I’ll walk you through what flood zone designations mean for South Seaford properties, what flood insurance will actually cost, and what to expect from an inspection on a home that was built in 1952. These aren’t details you want to learn after you’re under contract.
From there, I handle the offer strategy, the negotiation, and the coordination with attorneys, inspectors, and any contractors who need to weigh in. I have a referral network I’ve built over 15 years — people I personally stand behind — which matters especially in a market where aging oil heating systems and older electrical panels are common. The Seaford market moves fast. In November 2025, homes were selling in an average of 17 days. You need someone who can move with it.

We handle both sides of the transaction — buying and selling — across Seaford’s full range of property types. That includes the canal-front waterfront homes in South Seaford that require flood zone navigation and dock permit awareness, the post-WWII Cape Cods and ranches that make up the majority of the inland housing stock, and everything in between. As a Certified Buyer Broker, I carry a formal designation in buyer representation — meaning if you’re purchasing in Seaford, my job is specifically to advocate for you, not to split my attention between both sides of the deal.
For sellers in Seaford, we provide a complimentary market evaluation with no obligation. We’ll give you an honest read on pricing — not the number designed to win your listing, but the number that will actually move the home. In a market as small and as fast as Seaford, overpricing doesn’t just slow things down; it makes your listing visible in a way you don’t want it to be.
Beyond the transaction itself, we connect clients with a vetted network of Nassau County attorneys, home inspectors, contractors, and insurance agents. For Seaford specifically, that means people who understand what they’re looking at when they walk through a home built in 1950, and agents who can quote flood insurance accurately for a property sitting at 9.8 feet above sea level. These are the details that determine whether a deal closes cleanly or falls apart in the final week.
South Seaford’s canal-front properties are genuinely appealing — private docks, direct access to South Oyster Bay, and a lifestyle that’s hard to replicate anywhere else on the South Shore. But they come with real financial considerations that buyers need to understand before they fall in love with a listing. Much of South Seaford sits within FEMA AE flood zones, which means flood insurance isn’t optional — it’s required by most lenders, and it’s an ongoing annual cost that needs to be factored into your true cost of ownership.
Beyond the insurance question, waterfront properties in Seaford often involve bulkhead conditions, dock permits, and elevated mechanical systems — all of which should be examined closely during the inspection process. An elevation certificate is typically required for accurate flood insurance quoting, and not every inspector is equally equipped to evaluate these specific factors. Working with an agent who understands what to look for — and who has a referral network of inspectors and contractors familiar with South Shore waterfront properties — is the difference between a smooth closing and a costly surprise.
Seaford is a small market — roughly 5,200 housing units across just 2.61 square miles, with the overwhelming majority being owner-occupied single-family homes. That means inventory is limited at any given time, and when a well-priced home comes to market in Seaford, it moves. As of November 2025, homes in Seaford were selling in an average of 17 days, down from 24 days the prior year. That’s a meaningful acceleration in a market this size.
The median sale price in Seaford was approximately $730,000 as of late 2025, up 8.5% year-over-year. For buyers, that combination — fast absorption, rising prices, and thin inventory — means preparation matters more than patience. You need financing in order, a clear sense of what you’re looking for and where in Seaford you’re looking for it, and an agent who can move quickly when the right home appears. For sellers, the data suggests that correctly priced homes are finding buyers without extended market time, but overpriced listings in a market this small become visible quickly.
Yes, meaningfully. The Seaford Union Free School District is one of the primary reasons family buyers choose Seaford over neighboring communities like Wantagh and Massapequa, and that demand is reflected in pricing. The district maintains a 10:1 student-to-teacher ratio, spends roughly $31,424 per student annually, and posts strong state test proficiency scores — 73% in math and 69% in reading. For buyers with school-age children, those numbers carry real weight.
What this means practically is that homes zoned for the Seaford Union Free School District tend to attract a motivated buyer segment that is specifically choosing Seaford for the schools, not just settling for it. That sustained demand helps support values even when broader market conditions soften. If you’re selling a home in Seaford’s district, that’s a legitimate marketing point. If you’re buying and comparing Seaford to Wantagh or Massapequa, the school district question deserves an honest, specific conversation — not a generic endorsement.
A Certified Buyer Broker (CBB) holds a formal designation specifically in buyer representation. It’s not just a license to facilitate transactions — it’s training focused on advocating for the buyer’s interests throughout the process. That distinction matters more than it might sound, especially in a market like Seaford where transactions often involve complexity that a generalist agent may not be equipped to handle.
In practical terms, it means your agent is specifically working to get you the best outcome on price, terms, and conditions — not managing a dual relationship between buyer and seller. For Seaford buyers navigating flood zone disclosures, aging housing stock, or the nuances of a canal-front purchase, having someone in your corner with formal buyer-advocacy training makes the inspection negotiation, the attorney review, and the final walk-through a different experience. Post-August 2024, buyers are also required to sign a written buyer representation agreement before touring homes, so understanding exactly what your agent’s role is — and what they’re committed to — matters from the very first conversation.
The majority of Seaford’s housing stock was built in the late 1940s and 1950s, during the post-World War II suburban expansion that followed the opening of Sunrise Highway and the GI Bill housing boom. That means a significant portion of the homes buyers are looking at in Seaford are 65 to 75 years old. The bones of these Cape Cods and raised ranches are often solid, but aging systems are common — oil heating, older electrical panels, and roofing that may be at or near end-of-life are typical findings on inspection reports in this area.
That doesn’t mean these homes aren’t worth buying — many of them are well-maintained and represent real value in a strong school district with excellent commuter access. But it does mean the inspection process deserves serious attention, not a formality. A thorough inspector who understands what to look for in this era of construction, and a contractor who can give you realistic quotes on an oil-to-gas conversion or a roof replacement, are both worth having in your corner before you go under contract. My referral network includes exactly these kinds of vendors, and they’re people I’ve worked with long enough to trust.
The honest answer is that the public tools — Zillow, Redfin, online estimators — give you a starting point, but Seaford’s internal market variation makes them unreliable for precise pricing. A canal-front home in South Seaford with dock access and bay views commands a fundamentally different premium than a Cape Cod on a quiet inland street north of Sunrise Highway, even within the same ZIP code. Applying a single median to a market with that much internal range will either leave money on the table or price you out of the buyer pool.
A comparative market analysis — which we provide at no cost and with no obligation — looks at what homes have actually sold for on comparable streets in Seaford, in comparable condition, within a realistic time window. It accounts for the flood zone factor for South Seaford properties, the school district premium that family buyers are specifically paying for, and the commuter access value that the Seaford LIRR station and the Seaford-Oyster Bay Expressway bring to the table. With year-over-year appreciation running at 8.5% as of late 2025, many Seaford homeowners who haven’t looked at their numbers recently may be sitting on more equity than they realize. That conversation costs nothing and commits you to nothing.
