Finding a house in a city that never sleeps is kind of a nightmare right now. You look at Zillow, find a place you love, and—poof—it’s gone before you even finish your coffee. Honestly, the Las Vegas market has a way of chewing up casual buyers. That’s why people look for names like Mark Sivek Las Vegas realtor when they want someone who actually knows where the bodies are buried—metaphorically speaking, of course.
Mark Sivek isn't some new kid on the block with a fresh license and a shiny Instagram filter. He’s been in the weeds of Southern Nevada real estate for nearly three decades. We’re talking about a guy who started in 1997, right before the city went through its massive 2000s boom, the subsequent 2008 crash, and the wild pandemic-era surge. He’s seen the valley change from a gambling oasis to a professional sports hub. But being a veteran in this town comes with its own set of twists and turns.
The Reality of Working with Mark Sivek Las Vegas Realtor
If you’re hunting for a home in Henderson or Summerlin, you’ve probably seen his name pop up on Realty ONE Group listings. Sivek has built a reputation as a "deal maker" rather than just a guy who opens doors and shows you where the kitchen is. Back in the day, during the high-rise boom, he was known for helping buyers strategize their financing when things got messy. He’s basically the guy you call when the standard "30-year fixed and a prayer" approach isn't working.
Lately, his advice to buyers has been pretty blunt: stop trusting the big national websites. He’s gone on record with the Las Vegas Review-Journal explaining that sites like Zillow or Trulia are often lagging behind. By the time a "For Sale" sign hits your screen, the house might already be in escrow. His whole philosophy revolves around the local MLS—the Multiple Listing Service—and having an agent who is aggressive enough to call the listing agent before you even get in the car. He says it's simple: he who hesitates loses.
Experience That Goes Beyond Residential
A lot of people don't realize that Sivek’s background isn't just selling suburban three-bedroom houses. He’s managed over 25 million square feet of commercial real estate. That’s a massive amount of floor space. He’s also handled over 1,500 single-family homes in property management. This matters because it means he understands the "guts" of a property—the stuff that costs you money after you close—better than someone who just likes interior design.
His education is pretty solid, too. He grabbed a B.S. in Finance and Marketing from USC back in ’95. You can see that finance background in how he talks about "market velocity" and "inventory bottlenecks." He doesn't just tell you a house is pretty; he tells you if it’s a sound asset.
A Career Defined by Leadership and Controversy
You can't really talk about the current state of Mark Sivek Las Vegas realtor without acknowledging the elephant in the room. Real estate is a small world in Vegas, and leadership roles are everything. Sivek was a heavy hitter in the Las Vegas REALTORS (LVR) association for years. He served as the 2024 Vice President and was slated to be a director for the 2026 board.
Then things got complicated. In late 2025, Sivek found himself at the center of a massive social media firestorm. After the death of a prominent conservative figure, Sivek posted some incredibly incendiary comments on LinkedIn. He basically said the world was a better place without the individual and used some pretty colorful language to describe him.
The fallout was fast.

- The LVR President, George Kypreos, removed him from his leadership positions.
- He was fired from Realty ONE Group Las Vegas.
- He eventually issued an apology, but the damage to his "official" standing in the association was done.
It’s a classic case of how the digital age has changed the business. In the old days, a realtor’s private opinions stayed private. Now, one LinkedIn post can end a 20-year run in leadership. Does this affect his ability to sell a house? Probably not. But it definitely changed how he’s viewed in the corporate hallways of Nevada real estate.
What the Market Looks Like Right Now
So, if you’re looking at Mark Sivek for a deal in 2026, what are you actually walking into? The Las Vegas market is currently a weird mix of high demand and "sticker shock" inventory.
Henderson is still the crown jewel for families, and Summerlin South is where the luxury condos are moving. Sivek recently handled sales in the $500k to $1.2 million range—places like Pleasant Summit Drive and Cloud Tower Street. He’s active in the areas where people are actually moving, not just where the tourists go.
Why the "Expert" Tag Still Sticks
Despite the controversy, Sivek remains a "Top Agent" in the eyes of many industry publications. He founded 1st Priority Realty LLC years ago and grew it to over 50 agents. He’s the guy who started the "BE VOCAL SUPPORT LOCAL" campaign. He’s deeply entrenched in the Nevada Association of Realtors (NVAR) and has served on professional standards committees.
When you work with someone like this, you aren't just getting a salesperson. You’re getting someone who knows the legal contracts inside and out because he’s likely the one who helped write or enforce them in the past.
Actionable Steps for Vegas Home Buyers
If you’re trying to navigate the Las Vegas market and considering a veteran like Sivek, or anyone with that much experience, here is what you need to do:
- Get an MLS Feed Immediately: Don’t wait for the apps to update. Ask your agent for a direct portal. It’s the only way to see "Coming Soon" or "Back on Market" status in real-time.
- Verify the Listing Status: If you see a sign in a yard, don't assume it's available. As Sivek points out, signs stay up until escrow closes. Have your agent call the listing broker to find out if they are taking "backup offers."
- Look at the Management History: If you’re buying an investment property, ask about the rental history of the ZIP code. Vegas is a transient town; some areas have high turnover that can kill your ROI.
- Check the Ethics Record: Before signing an exclusive buyer's agreement, look at the agent's history with the local board. While personal opinions on social media are one thing, professional grievances are another.
Las Vegas real estate is a full-contact sport. Whether you’re looking for a high-rise condo or a quiet spot in the suburbs, the key is moving fast and having a guy who knows how to navigate the paperwork when things get messy.

To get started, you should pull a recent market report for your specific target neighborhood—like Enterprise or Summerlin South—to see the "days on market" average. This will tell you exactly how much time you have to make a decision once a house hits the MLS. You can also reach out to a local broker to set up an automated search that bypasses the lag of national real estate portals.
