Fact

I buy things that have rats in the cellar and holes in the roof — I look for the worst properties because that's where the value is.

Mark describes his strategy of buying dilapidated brownstones with significant damage, which allows him to add value through restoration.

transcript

Mark O'Brien: I usually buy things that have rats in the cellar and holes in the roof and water damage everywhere, mold, and problems. But this one, when I walked into it, I was like, 'This is cute.' It's 180 years old.

Mechanism

Time will kill every deal — the cost to carry a property through years of permitting and regulatory hurdles is the real challenge.

Mark explains that the permitting process for a landmarked brownstone can take years, and that carrying costs during that period are what destroy deal profitability.

transcript

Mark O'Brien: It's been two and a half years that I've been waiting for permits. It's landmark. It's a lot of work of architects, engineers getting soil bearing tests. They've got to break up the foundation down below. It's the cost to carry it. Time will kill every deal. And often it does.

Anecdote◆

Desperation drove me into real estate — I was completely overleveraged and had to make it work.

Mark explains that he got into real estate not from strategic planning, but from being overleveraged and desperate, having taken on a house he couldn't afford.

transcript

Mark O'Brien: I spoke to a guy about this recently and he was like, 'Well, how did you get into real estate? What was that thing that made you get into real estate?' And I said, 'Desperation.' I had two and a half kids. I was living in Greenwich, Connecticut in a house that I had no right to. I was completely overleveraged.

Claim◆

The business scores an 8 out of 30 — it doesn't make that much money for the work involved, can't run without Mark, and has a weak moat because anyone with enough capital could do it.

Sam scores Mark's business low: modest income relative to effort, poor scalability without Mark's direct involvement, and a thin competitive moat since deep-pocketed competitors exist.

transcript

Sam (host): In terms of money, this business was a pain in the butt and I don't think it made that much money. I'm going to give it a three. Second, machine — can it run without him? He's really the catalyst. I'm going to give it another three. And for moat — anyone with enough money could probably do it. I'm going to give it a two.

Data◆

On a 4.8 million dollar investment over three years, selling for 6.2 million, you make roughly $500,000 a year — but that's on a good year; on a bad year you can lose money.

Sam calculates that Mark's profit margin on a typical brownstone project yields about $500k/year, but he notes the business is cyclical and can lose money in bad years.

transcript

Sam (host): I think that he probably does something like $500,000 to a million dollars a year in income, but that's on a good year. On a bad year, he can lose money and it was just a lot of work for that amount of money.

Claim

The lifestyle scores a 21 out of 30 — high pride in the work, great coworkers, but limited freedom because projects consume weekends and demand constant attention.

Sam rates the lifestyle highly for pride in craftsmanship and enjoyment of the crew, but marks down freedom because Mark is always on call, even on weekends, dealing with regulations and project management.

transcript

Sam (host): For pride, he was very proud of what he was doing. I was actually proud for him. I'm going to give that one a nine. People, I met some of his co-workers, it was awesome. I'm going to give it a seven. And now, freedom — I'm going to give this one a five. He's always on the phone dealing with regulations. The lifestyle score gets a 21 out of 30.
