The final whistle hadn’t even faded when Manny Fisher bent over, hands on his knees, catching his breath and grinning at the same time. Tuesday evening pickup games at the rooftop pitch in Brickell had become something of a ritual — part stress release, part networking, all Miami. The city spread out below them in every direction, a postcard of glass towers, Art Deco rooftops, and the last copper light of a February sunset dissolving into Biscayne Bay.
He grabbed his water bottle and drifted toward the railing, the way you do when the view earns it. A man in his late fifties was already standing there — still in his cleats, a little winded, watching the city like he owned a piece of it.
As it turned out, he did.
“Hell of a game,” the man said, not looking over. “I haven’t played in three years. My knees are going to remind me of that tomorrow.”
Manny laughed. “Worth it though.” He extended his hand. “Manny Fisher.”
“Carlos Santiago.” A firm shake. “You play here often?”
“Every other Tuesday when I can manage it. You?”
“First time. I own the building across the street — the mixed-use on Brickell. One of my tenants told me about this place. I figured, why not.” He gestured vaguely at the pitch behind them. “Good to see what’s happening up here. I’m always thinking about my rooftop. What else you could do with it.”
Manny tilted his head with a familiar kind of interest. The kind that comes naturally when you spend your days thinking about how buildings can work harder for their owners. “What kind of building?”
“Mixed-use. About 110,000 square feet. Retail on the ground floor, office on two through five, residential on six through ten. Been in the family about eight years now.”
“Great asset class for this market,” Manny said. “You managing it yourself?”
“Mostly. I’ve got a small team. But I stay close to it.” Carlos turned to look at him. “What do you do?”
“Value-add real estate advisory. I work with owners — usually mid-size commercial and mixed-use — to find where their asset is underperforming. Sometimes that’s the physical plant, sometimes it’s the lease structure, sometimes it’s on the tax side.” He paused, then added with a half-smile, “Sometimes it’s all three.”
Carlos was quiet for a moment. “Tax side,” he repeated, as if the phrase had snagged on something. “I just got off the phone with my CPA last week. He’s been after me about something called cost segregation. I told him I’d look into it after tax season.”
Manny turned to face him fully now. “After tax season? Carlos, cost segregation is tax season. That’s exactly the conversation you should be having right now.”
Carlos leaned against the railing. “Alright. You’ve got me curious. What is it, exactly? My CPA explained it but I want to hear it in plain English.”
Manny settled in. This was a conversation he’d had many times — on job sites, in conference rooms, over coffee — but there was something about this particular rooftop, this particular city glowing below them, that made it feel worth taking his time with.
“The IRS says you depreciate a commercial building over 39 years. Straightforward, slow, predictable. Every year you’re taking roughly the same deduction. But here’s what most owners don’t realize — a building isn’t one asset. It’s hundreds of assets bundled together. The lighting system. The specialty plumbing. The flooring. The land improvements. Certain tenant improvements. Each of those components has a different useful life.”
“A cost seg study — done by engineers who specialize in exactly this — goes through your building piece by piece and reclassifies those components into shorter depreciation schedules. Five years, seven years, fifteen years instead of 39. And when you layer bonus depreciation on top of that, you’re not waiting decades for those deductions. You’re capturing them now.”
Carlos straightened. “How significant are we talking?”
“On a building your size, potentially very. Let’s say conservatively that $4 to $6 million of your asset gets reclassified into shorter-life components and qualifies for bonus depreciation. You could be looking at deductions in that range — and at a 37% federal rate, you’re talking about real money back in your pocket. Seven figures isn’t out of the question depending on how the study comes back.”
Carlos let out a low whistle. “And I’ve owned this building for eight years without doing this.”
“You’re not alone. But here’s the good news — that’s actually not a problem. The IRS allows what’s called a catch-up. Through a method change, you can claim all the depreciation you would have taken in prior years in a single tax year. No amended returns. One filing.” Manny paused to let that land. “So the clock not having started yet isn’t a penalty. It’s just deferred value sitting there waiting.”
They had moved away from the railing now, finding a couple of chairs near the edge of the pitch as the other players filtered out. Someone had brought out cold Presidente bottles and passed them around without asking. Miami operating as Miami.
“Okay,” Carlos said, leaning forward with his elbows on his knees. “So what do I need to know? What are the things I should be doing — and the things I need to avoid?”
Manny appreciated the question. It was the question of someone who was actually going to act on this, not just file it away.
“Let me walk you through both,” he said.
What You Want to Do
“First — and I can’t stress this enough — make sure the study is done by a qualified engineer. Not your bookkeeper, not a generalist CPA, not someone who offers it as an add-on service they learned from a webinar. This needs to be someone who can actually inspect the property, understands construction cost methodology, and can defend every line of that report if the IRS ever asks. Because that report is your armor.”
Carlos nodded slowly.
“Second, confirm that your tax situation actually supports it. You’re actively managing this asset, which puts you in a better position than a purely passive investor. But your CPA needs to look at your full income picture — other properties, other income sources, how your entity is structured — to confirm you can actually absorb and deploy these deductions in the year they hit.”
“Third, since you’ve owned the building for eight years, make sure your team looks seriously at that catch-up opportunity. That’s potentially years of accelerated depreciation you’ve been leaving on the table, and capturing it in one year can be a significant event on your return.”
“And here’s one that people consistently overlook — documentation. After the study is done, you keep everything. The full engineering report. The asset schedules. The cost allocation methodology. Construction contracts. Photos from the site inspection. Every supporting invoice. The IRS audit window on depreciation can stretch years out, and when they come — if they come — they don’t want your word for it. They want the paper trail. Organize it, share it with your CPA, make sure it’s integrated into your tax file and not sitting in someone’s email inbox.”
What You Want to Avoid
“Now the other side.” Manny took a sip of his beer. “Don’t use a provider who guarantees you a number before they’ve even seen the building. That’s not a study, that’s a sales pitch, and it won’t survive scrutiny. Legitimate cost seg is based on an actual physical inspection and a real analysis of your specific property. Anyone promising outcomes before they’ve done the work is selling you something that could come apart at the worst possible moment.”
“Don’t forget about depreciation recapture on the back end. Cost seg is a deferral strategy — it’s not making taxes disappear. When you eventually sell, the IRS recaptures that accelerated depreciation, up to 25% on real property. That’s not a reason to walk away from the strategy. It’s just a reason to plan your exit thoughtfully. A 1031 exchange, a long-term hold plan — these things need to be in conversation with each other.”
“And don’t treat the study as a one-time event. If you do significant capital work — new HVAC, tenant build-outs, a major renovation — those improvements may open up new reclassification opportunities. The study should live in your ecosystem, not gather dust in a drawer.”
“Most importantly,” Manny said, “don’t do this in a silo. Your CPA, the cost seg engineer, your attorney — they need to be coordinating. The strategy only performs at its ceiling when everyone’s working as a team.”
Carlos sat back and was quiet for a moment. Below them, the city hummed along, indifferent to the conversation happening above it. A building with 110,000 square feet of untapped tax strategy sitting right across the street.
“I’ve been leaving money on the table for eight years,” he said finally. It wasn’t quite a question.
“Potentially, yes. But the good news is you’re having this conversation in February, not April 16th.” Manny smiled. “There’s still time to do this properly.”
Carlos shook his head in the way people do when something both frustrates and energizes them at once. “I want to bring this to my CPA. He’s already been nudging me — I want to come to him with something more concrete.”
“That’s exactly the right move,” Manny said. “Here’s what I’ll do — I’ll send you a recap tonight. The key points we covered, the framework for thinking about it, the questions you should be bringing to your CPA so that conversation is actually productive and not just surface level.”
“I’d appreciate that.”
“And let’s do this — after you’ve had that conversation, let’s sit down together. You, me, and ideally your CPA in the room or on the call. We can get into the specifics of your asset and figure out whether a study makes sense, who the right provider would be, and what the realistic range of outcomes looks like for a building your size and age.”
Carlos extended his hand. “Tuesday work for you? That gives me the weekend to talk to my CPA.”
“Tuesday works.” Manny shook it. “Send me his contact information if you want me to reach out to him directly. Sometimes it helps to have the conversation at the same time.”
They sat for a few more minutes as the rooftop cleared out around them, two people who had come up here for a pickup game and left with something that might be worth considerably more than ninety minutes of exercise.
Later that evening, true to his word, Manny sent the following email. (Italic)

Subject: Cost Seg Recap — Good Conversation Tonight
Carlos —
Great meeting you up there. Here’s the quick recap I promised, organized so you can walk into your CPA conversation with a clear framework. Looking forward to Tuesday.
