Watch this Space

What can you learn about New York real estate from Mark’s latest videos? A lot. Here are three takeaways for buyers (and dreamers) from clips that people can’t stop watching:


Respect the soul of a building

In Greenpoint, a historic church was butchered. Mark’s stance?Restore history to remember history or buy a different building.” When you preserve a piece of the past, you’re investing in meaning, memory, and the character that never goes out of style.
 


Look beyond the square footage — what’s the story?

The Breakfast at Tiffany’s townhouse is deserving of her $15M price tag — it’s cinematic history, woven into decades of pop culture. Homes with stories carry weight and allure that a new build simply can’t match.

 


Value the lived-in wisdom.

One of Mark’s favorite interviews? A sharp, sassy New Yorker who’s been in her $45,000 Bank Street studio for nearly 60 years. Her line: “NYC is for the rich and the quick.” It’s proof that longevity, grit, and perspective are priceless in this city and sometimes the smallest spaces hold the biggest lessons.
 


Hot Spots

252 East 7th Street #1B — East Village, Manhattan — $550,000 
People overlook smaller spaces, but this one punches way above its weight. It’s not about square footage—it’s about soul. The built-ins, the parlor floor, the cabin feel in the East Village? That’s romance you can’t stage. This is for someone who sees space as storytelling.

 

21 South William Street #5D  — Financial District, Manhattan — $875,000 
A sun‑soaked 1‑bed, 1‑bath condo in the historic Block Hall building, featuring soaring 10′ ceilings, oversized windows, and a Juliet balcony with South/West views.
 
 

COMING SOON: 94 Bank Street — West Village, Manhattan A true West Village gem. Built in 1899, this Greek Revival rowhouse is loaded with quirks that give it soul — marble mantles, pocket doors, pine floors, even a sunlit garden off the kitchen. It’s the kind of home that feels more like a story than a listing.
 
 
 
 

Mark on the Mic

Mark joins Glennda Baker to talk about what it really means to build, sell, and storytell in real estate. From pivoting into development and pulling off $175M+ in transactions, to why history matters in every renovation, to what’s next for him — this one’s equal parts passion, fun, and big-picture perspective.
 
 
 

In the News: TikTok's ‘Brownstone Whisperer’

Before the cameras, Mark was literally ripping up 1800s floorboards—not for clicks, but to know what they cost to fix. That honesty—raw, ratty, and real—turned a renovation moment into TikTok stardom. Inman dives into Mark’s journey from DIY renovator to NYC’s go-to for rugged, soulful brownstone stories.
