Rex Heuermann House: His $500,000 Massapequa Park, New York Ranch

Picture a quiet suburban street on Long Island where nothing seems out of the ordinary — until you learn the story behind one particular home. If you have ever followed true crime news, you likely know about Rex Heuermann House.

His house sits in Massapequa Park, a modest 1,323 square-foot red ranch built in 1956 with six rooms, one bathroom, and a full basement that later became central to one of New York’s most chilling investigations. He purchased the property in 1994 for $170,000 — the same year he launched his architecture firm in New York City. From the outside it looked ordinary, hiding a far darker story. 🏚️

Rex Heuermann House Location

• Full Address:105 First Avenue, Massapequa Park, NY 11762

The Rex Heuermann House Located on the South Shore of Long Island by its red-shingled exterior and white storm door, the house sits just north of Michigan Avenue. This quiet suburban residence gained international notoriety in 2023 when it became a primary site for the Gilgo Beach forensic investigation, drawing global attention to this otherwise peaceful Nassau County neighborhood.

Rex Heuermann House Tour

Hi, I’m Stefano Schiavon from Rivon Home. I have to be honest — when my colleague Marcus, a crime reporter covering Long Island, suggested we check out Rex Heuermann House, I wasn’t sure what to expect. We drove from the city on a gray Tuesday morning, and as we turned onto First Avenue, the house came into view. It’s smaller than you imagine — a quiet red ranch among neat neighboring homes.

Standing outside, there was an eerie stillness. Marcus pointed out the cluttered porch, a woodworking bench, and the dug-up backyard where police had searched with cadaver dogs and ground-penetrating radar. I thought to myself — this is the work of a man who designed major New York buildings for 30 years, yet here it sits, deceptively ordinary.

Inside Rex Heuermann House: Interior and Other Features

The interior remained largely unchanged since the 1950s in Rex Heuermann House, with investigators meticulously searching for evidence of potential crimes committed within its walls.

Grand Entrance

Walking up to the front door at Rex Heuermann House, you are greeted by a plain white storm door — no grand foyer, no architectural statement. For a man who spent his career designing spaces for others, his own entrance is strikingly bare.You step directly into a small, tight living area with low ceilings that feel even lower given the weight of what happened here. The porch outside is stacked with cut wood from his woodworking hobby.

There are no chandeliers, no marble flooring, no design details worth noting. It is a 1950s Long Island ranch — untouched and unrenovated for decades.This desert estate in Ivins, Utah, is a sprawling 9,000-square-foot “concrete fortress” that served as the secluded site for the crimes of Jodi Hildebrandt and Ruby Franke.

Bedrooms

Rex Heuermann House follows a classic six-room ranch layout, which means the bedrooms are compact and purely functional. Small windows, basic finishes, and standard closets define each room. There is no master suite in any meaningful sense — no walk-in closet, no attached bathroom, no luxury touches.

The rooms feel like time stood still somewhere around 1975. For a household that included a wife and two children for many years, the space must have felt tight. Nothing about these rooms reflects the professional life of a successful Manhattan architect.

Bathrooms

There is only one bathroom in the entire Rex Heuermann House — and I mean one. No marble countertops, no rainfall showerhead, no double vanity. Just a tub, a toilet, and a sink.

For context, this is a man who spent over 35 years consulting on high-end construction projects across New York City, including facilities for major organizations. The bathroom tells you everything about how Rex chose to live at home versus how he worked professionally. The contrast is honestly striking. 🛁

Living Spaces

The total living space of 1,323 square feet means every room is doing double duty. The living area opens directly into the dining space with no formal separation. There is no home theater, no game room, no spa, and no entertainment space of any kind.

Furniture is simple and well-worn. The whole layout feels like a snapshot of mid-century suburban life, frozen in place. You walk through it and feel the decades — not as charm, but as neglect. For a property owned by an architect, the lack of any design investment is what stands out most.

Kitchen

The kitchen is small, dated, and purely utilitarian in Rex Heuermann House. Basic countertops, older appliances, and a layout designed for one person cooking at a time — that is what you find here. There is no kitchen island, no open-plan flow, no modern upgrade of any kind.

It is the kind of kitchen that makes you wonder how a family lived and cooked here for decades without ever updating a single thing. The contrast between the high-end Manhattan kitchens Rex was likely consulted on professionally and his own home kitchen is almost impossible to ignore.

The Basement

This is the room in the whole Rex Heuermann House everyone wants to know about, and I have to tell you — it earns its reputation. The basement is the most significant space in the entire house. During a 12-day search by Suffolk County police, New York State police, and the FBI, authorities discovered a steel vault in the basement containing 279 pistols and long guns.

The basement also served as Rex’s personal woodworking workshop where he built furniture. A second search in May 2024 focused again on the basement as the primary area of interest for investigators. This is not a wine cellar or a home gym — it is the dark center of this entire story. 😳

Security and Privacy

There is no gated entry here, no surveillance system, and no landscaping buffer to speak of. Rex Heuermann House sits completely open on a quiet residential street. Since Rex’s arrest, the property regularly draws visitors and true crime enthusiasts who stop to photograph the house from the sidewalk.

During the active investigation period, a police officer was stationed outside to manage media and public access. The irony is that a house with no security became one of the most watched properties in Nassau County.

How Much Is Rex Heuermann’s House Current Price?

Rex purchased this property for $170,000 in 1994. Given its current state of disrepair and the notoriety surrounding it, market estimates place the land value today somewhere between $400,000 and $500,000 — and that value is primarily for the lot itself, not the structure.

Real estate analysts believe the most likely outcome is that the house gets torn down entirely and replaced with a new starter home. The dark history of the property may reduce buyer interest from traditional homebuyers, though true crime tourism has already brought a steady stream of foot traffic to the block. 💰

Rex owns a timeshare unit in Las Vegas at 5499 W Tropicana Avenue, Apartment 1012. This property was flagged during the investigation as Las Vegas authorities began reviewing whether Rex had any connection to unresolved local cases. The unit is a standard timeshare-style apartment — not a luxury residence by any measure.

South Carolina Property — Remote Area, SC

Rex had reportedly planned to retire in a remote area of South Carolina, where his brother currently lives. This property was purchased as a retirement plan for Rex and his wife. Following his arrest in 2023, his estranged wife Asa Ellerup and their children relocated to South Carolina, and this property appears to have become their primary residence after leaving Massapequa Park.

Manhattan Office — 385 Fifth Avenue, New York, NY

Rex was the founder and president of RH Consultants and Associates, Inc., an architectural consulting firm based at 385 Fifth Avenue in Midtown Manhattan. While not a residential property, this office was a significant professional asset representing nearly 30 years of his career. As of 2023, the firm has been permanently closed and his assets are under scrutiny as part of the ongoing legal proceedings.

Where Does Rex Live Now– How He Get Arrested.

Rex Heuermann remains incarcerated at the Suffolk County Jail, where he has been held without bail since his arrest in July 2023. His capture followed a major breakthrough when investigators linked his DNA from a discarded pizza crust to a hair found on one of the victims.

He currently faces charges for the murders of seven women, spanning over three decades of alleged crimes. While he maintains his innocence and awaits a trial scheduled for late 2026, his family has relocated to South Carolina to seek privacy and rebuild their lives away from the intense media scrutiny in New York.

Rex Heuermann Net Worth: How Much Money Does He Have?

Rex built his career as an architecture consultant over more than 35 years, and by most accounts had accumulated meaningful wealth before his arrest. Estimates vary widely — ranging from $1.5 million to $7 million depending on the source.

At the time of his arrest, records showed he and his wife owed $81,500 in personal income tax and approximately $209,000 in additional taxes to the IRS. After accounting for all known liabilities, his net worth is currently estimated to be close to $1.5 million. His firm is permanently closed and his financial accounts remain frozen pending the outcome of the legal proceedings.

Conclusion

Taking you through the house linked to Rex Heuermann House has been one of the most unusual walkthroughs I’ve ever done — and I’ve seen a lot of homes. This isn’t a story about luxury or inspiration. It’s a stark reminder of how a modest 1,323-square-foot ranch in New York became one of the most infamous properties in the country.

From the worn floors to the cluttered exterior and unsettling details inside, every part of the house tells a story far beyond architecture. Yet from a design perspective, it’s interesting — many of my clients are drawn to classic 1950s Long Island ranch layouts. With the right vision, even a home with simple bones like this can be transformed into something warm, functional, and beautiful — much like the grounded, practical charm you see in the Parker Schnabel house.
