Real estate expert Ryan Serhant warns of self-destructive mistake homebuyers make to save a dollar

Isaac Newton famously said, "what goes up must come down."

According to celebrity real estate icon Ryan Serhant, Newton's law of gravity applies just as well to the housing market.

Serhant, who's helming Netflix's new NYC-based real estate show, "Owning Manhattan," addressed current market woes in an interview with Fox News Digital — explaining the ebbs and flows of the challenging housing landscape and revealing the one thing people looking to buy real estate do wrong.

"Housing is defined by three things and three things only: supply, demand and interest rates. So, when you have a rapid rise in interest rates, everyone's going to call the end of the housing market. And when you have a rapid decline in interest rates, everyone's going to call the boom. Markets go up, markets go down," he explained.

CELEBRITY REAL ESTATE AGENT SHARES 'RICH AND FAMOUS' CLIENTELE'S WILD REQUESTS

"I'm biased, but the No. 1 mistake most clients make is not using an experienced real estate agent," Serhant revealed at the blue carpet event for his new show, streaming now.

"You wouldn't operate on yourself. You wouldn't represent yourself in court, right? So use a professional. They're there for a reason," the real estate expert urged. "It's all about that price point at the end of the day, so use somebody who wakes up and breathes real estate. Don't try to save a dollar, because you will cut your nose to spite your face every single time."

"People need a place to live. And we're here to help them find it," he added.

4 KEY STRATEGIES FOR HOMEBUYERS IN TODAY'S CHALLENGING MARKET

Serhant spoke to Fox News Digital about why he believes ‘Owning Manhattan’ is especially "relatable" to interested homebuyers amid current market uncertainty.

THE LEAST AFFORDABLE CITIES FOR POTENTIAL HOMEBUYERS

"I think [it's] an aspirational show. It's not just about .01% homes. It shows those, but it shows everything. We show real estate across price points, and we show the ups and downs of entrepreneurship," he explained.

"The cast of agents that work with me on the show… [it] follows about 12 of them. Half of them are veterans. They've been in the business, and they're trying to keep their perch. The other half are brand new," he continued. "If you want to sell real estate to your city, you're signing up for no salary, no benefits, and you're signing up for a business where over 85% of the people that get into it quit in the first year. There's a churn because it's incredibly, incredibly difficult. So you're going to be able to watch that in a way that you don't see on ‘Selling Sunset’ or the buying shows, or even ‘Million Dollar Listing,’ which I think is exciting for people. You'll be able to relate more to this one."

"I think the American dream for homeownership has not changed; I think the dreams have changed."

- Ryan Serhant, founder of SERHANT.

Despite average mortgage interest rates hovering around 7%, in a landscape where New York City home prices cost roughly $785,000 on average, Serhant told Fox News Digital he believes the American Dream of homeownership hasn't changed.

If anything, he explained, it's only "gotten bigger."

"I think the American dream for homeownership has not changed; I think the dreams have changed. I think people have different types of dreams now. They have multiple dreams. They're not thinking about just their primary home with a fence for their kids. They're now having dreams about, you know what? Maybe I'll rent, because I want to have a second home in New York City."
