Last week a client of mine — a Doral-based logistics company doing $14M in annual revenue — handed me a question that I'm hearing more and more in 2026:

"Carlos, my landlord just sent me a renewal at $44 a square foot. We've been here seven years. Should we just buy the building?"

The honest answer is: probably yes, and you should have asked me three years ago.

But that's the kind of question every Miami business owner needs to be asking right now. The market dynamics in commercial real estate have shifted hard since 2023 — rents are up, sublease vacancies are stabilizing, interest rates have settled into a more predictable range, and the tax code still rewards real estate ownership in ways your CPA may not have fully walked you through.

Let's break it down the way I would on a call with a client.

The Lease Side of the Equation

In 2026, asking rents for Class A office space in Miami's core submarkets — Brickell, Wynwood, Coral Gables, Doral — are running between $52 and $98 per square foot, full service. That's after a roughly 22% climb over the past three years. Pair that with annual escalations of 3–4% baked into most leases, and a ten-year lease on a 5,000-square-foot office in Brickell will cost your business north of $3.2M in rent alone. None of that creates equity. None of it offsets your taxes beyond a straight deduction. And at the end of the lease, you have exactly what you started with — a key card, a coffee machine, and a renewal letter.

For a fast-growing business that's certain about its space needs for the next 7+ years, leasing is almost always the more expensive long-term path.

The Buy Side of the Equation

Here's where it gets interesting. Let's use the same Doral example. A 5,000-square-foot office condo in a Class B+ Doral building is currently trading around $370–$425 per foot. Call it $2M acquisition. With an SBA 504 loan — which I suggest every Miami business owner explore — you're looking at 10% down ($200K), 40% covered by a long-term, fixed-rate CDC loan, and 50% covered by a conventional bank loan.

Your monthly debt service on that structure runs about $13,500–$15,000 in 2026 rate environments. Compare that to the $19,000–$24,000 monthly check you'd be writing your landlord for the equivalent leased space, and the cash-flow math starts to favor ownership immediately — sometimes from month one, almost always inside year three.

But the real magic isn't the cash flow. It's the tax structure.

The Self-Rental Move That Most CPAs Skip

This is where Miami business owners build serious wealth without working harder. The play looks like this:

You set up a separate LLC that owns the commercial property. Your operating business — the one your customers know — leases the space from that LLC. The rent flows out of your operating company (deductible business expense) and into your real estate LLC (where you can offset it with depreciation, mortgage interest, and operating expenses).

The money never really leaves your control. But the structure changes the tax character of those dollars in your favor. As I covered in my article 'Depreciation and 1031 Exchanges: The Miami Real Estate Tax Strategy Your CPA Hasn't Fully Explained,' depreciation alone can shelter 30–60% of your rental income on commercial property — and that's before you layer in cost segregation.

Cost Segregation: The Lever That Hits in Year One

A cost segregation study on a $2M commercial property in Miami can typically reclassify 18–28% of the building's value into 5, 7, and 15-year depreciation buckets — which means you can take massive deductions in year one rather than spreading them over 39 years.

For a Miami business owner in the 37% federal bracket, that often translates to $80,000–$140,000 in first-year tax savings on a $2M property. That's not a typo. That's the deduction that pays for the down payment.

Your CPA may not bring this up unless you ask. Engineering firms specializing in cost seg charge $4K–$8K for a study and the ROI is almost always 10x or better in year one alone.

When Buying Doesn't Make Sense

I'm not going to pretend ownership is right for everyone. Here are the situations where I tell clients to keep leasing:

1. Your headcount is growing more than 25% per year and you can't predict your space needs in 24 months.

2. You're in an industry that requires constant location moves (some retail, certain creative agencies).

3. You don't have the liquidity to put 10–20% down without straining operating cash flow.

4. You're planning to sell or merge the business within 3 years.

For everyone else, the math in 2026 favors ownership — particularly for Miami's professional services firms, medical practices, law firms, e-commerce operators, and family-run businesses where the owner intends to be there for the next decade.

The Trick Most Owners Miss: Buy More Than You Need

Here's a play I've helped several clients execute. Don't buy 5,000 square feet for your 5,000-square-foot business. Buy 8,000 and lease out the extra 3,000 to a complementary business. Now you have:

- Your operating space at "owner cost" (often below market)

- A passive income stream from your tenant covering 30–45% of your debt service

- A larger asset that appreciates on the full 8,000 feet

- A bigger depreciation base for tax purposes

Brickell, Coral Gables, Doral, and parts of Wynwood and Miami Design District have boutique office condo buildings perfect for this play.

Miami Market Snapshot — May 2026:

- Median sale price for Class B office in Doral: $382/sqft (up 6.4% YoY)

- Brickell Class A asking rents: $84–$98/sqft, full service (up 22% over 3 years)

- Office condo absorption in Coral Gables: ~340,000 sqft trailing 12 months

- SBA 504 average rate for May 2026: 6.91% — fixed, 25-year amortization

What I'd Tell My Best Friend

If you're a Miami business owner with stable revenue, predictable space needs, and a 7+ year time horizon — start the conversation now. Commercial inventory has loosened slightly in early 2026 versus the squeeze we saw in 2024, but the better deals tend to trade off-market through brokers who know which owners are ready to sell.

That's where someone like me earns their fee. I've helped Miami business owners walk into properties that never hit MLS, structured deals with seller financing to reduce the down payment, and run the numbers side-by-side against their lease so they can see exactly when ownership starts winning.

Your business is making someone wealthy with every rent check. The question is whether that someone is your landlord or you.

Frequently Asked Questions

Q: Should a Miami business owner buy or lease office space in 2026?

A: For businesses with stable revenue and 7+ year horizons, ownership typically wins by year three to five thanks to equity build-up, tax shields, and rent escalations being eliminated. Leasing still makes sense for high-growth or short-horizon businesses needing flexibility.

Q: What is an SBA 504 loan and why does it matter for Miami commercial real estate?

A: It's a federal loan program that lets owner-occupied businesses buy commercial property with just 10% down. The loan is split between a bank (50%) and a CDC (40%) at long-term, fixed rates — making ownership accessible to small and mid-sized Miami businesses without massive capital.

Q: Can I deduct depreciation on commercial real estate in Miami?

A: Yes. Commercial buildings depreciate over 39 years on a straight-line basis, but a cost segregation study can accelerate 18–28% of the value into 5, 7, and 15-year buckets — generating five- and six-figure first-year deductions for Miami business owners.

Q: How much office space should I buy if I want to also lease part of it out?

A: A common Miami strategy is to buy roughly 1.5x to 2x your current need. You occupy your portion at "owner cost" while leasing the surplus to a complementary tenant whose rent covers a meaningful share of your debt service. Boutique office condos in Brickell, Coral Gables, and Doral suit this model best.
