Rex Heuermann’s Net Worth: How Rich is the Suspected Serial Killer?

Born on September 13, 1963, to Dolores and Theodore “Theo” Heuermann as one of their five children, Rex Andrew Heuermann’s early years were reportedly far from normal. That’s because he not only had a bizarrely close relationship with his allegedly controlling mother but was also traumatized by his reportedly abusive father until the latter passed away in 1975. It is believed that his childhood shaped who he eventually became – an alleged serial killer – yet, as per Netflix’s ‘Gone Girls: The Long Island Serial Killer,’ he was also a hardworking family man.

How Did Rex Heuermann Earn His Money?

It was back when Rex Heuermann was growing up in the residential community of Massapequa Park, Long Island, that he understood the significance of ambition and perseverance. That’s because, as the son of a homemaker and a World War II Air Force veteran from a big family, he was quite young when different kinds of responsibilities started being placed on him. This ultimately even led him to begin working as a teenager, and he took complete advantage of hailing from the expansive, densely populated land that extends into the wondrous Atlantic Ocean.

In fact, young Rex primarily worked in the Parks Department at Jones Beach in Nassau County or as a Ranger in similar beach areas, resulting in him knowing the ins and outs of the island. Though, he seemingly also dedicated a lot of his time to serving in these positions and simply exploring his hometown owing to the fact he didn’t really have a social life — he was allegedly “everybody’s punching bag” in high school. However, things changed once he graduated from Berner High School and enrolled at the New York Institute of Technology for his Bachelor’s before finally kickstarting his career as an architecture consultant in Manhattan in 1987.

According to reports, Rex worked at a few different organizations before establishing his own architecture consultancy firm, called RH Consultants and Associates, in 1994 at 385 Fifth Avenue. That’s around the same time the rather newly divorced yet determined entrepreneur also bought his childhood home from his mother for $170,000, only to never leave — that’s where he settled with his second wife (now ex) and their two kids. Yet, it’s imperative to note that this architect wasn’t the kind who drew up plans for new constructions, massive skyscrapers, or dream houses; instead, he was more of an expediter as well as a troubleshooter who helped people get past red tape.

From what we can tell, Rex dedicated every bit of himself to RH Consultants and Associates, which is how the company thrived under even the worst economic circumstances and had an office right in the luxurious heart of Manhattan. As time passed, even his daughter, Victoria Heuermann, joined the business to help him further expand their scope, only for everything to turn upside down with his July 2023 arrest for allegedly being the Long Island Serial Killer. After all, once he was taken into custody on three charges of first-degree murder with suspicion of at least 8 more – he has since been indicted on four additional first-degree murder charges – the organization had to close its doors for good.

Rex Heuermann’s Net Worth

Considering Rex’s successful career as an architecture consultant over a period of more than 35 years, it goes without saying that he had likely managed to accumulate significant wealth for himself and his family prior to his arrest. The average income of someone in his position in Manhattan was reportedly $60,000 in the 1990s, $80,000 in the 2000s, $110,000 in the 2010s, and around $140,000 in the early 2020s, so of course, he was more than comfortable. He undeniably had operational expenses like rent, salaries, marketing, etc, along with his personal expenses as a family man, but the fact he already owned his own home and carefully invested definitely helped him a lot as time passed.

In fact, as per reports, Rex has an expansive property portfolio that spans three states and is currently worth around $1 million. Apart from his Massapequa Park home in Long Island, where his second ex-wife and kids still reside, he has a 2-bed, 2-bath condo in Las Vegas, Nevada, as well as a plot of land in Chester, South Carolina. He had bought the latter with plans to retire there so as to be closer to one of his brothers, whereas he and his second ex-wife, Asa Ellerup, had purchased the Vegas apartment together in 2005. As if that’s not enough, Rex had even invested both time as well as money to build a firearm collection worth hundreds and thousands of dollars – he had over 300 pieces at one point.

The authorities have since seized all his weapons, which he kept in the basement of his never-renovated home, and have likely even frozen all his bank accounts owing to the criminal charges against him. However, they can not touch his properties, except to obviously search them if they have a proper warrant, because the now 61-year-old allegedly didn’t commit any offenses there. We should also mention that according to records at the time of Rex’s arrest, he and his wife owed $81,5000 in personal income tax as well as around $209,000 in other taxes to the IRS. Therefore, while his combined assets could be worth well above two million dollars, we also have to take into account his liabilities. After considering all that, we estimate Rex Heuermann’s net worth to be close to $1.5 million.
