How Unchecked Operating Expenses Quietly Drain Your Bottom Line

I’ve sat in countless boardrooms with executives who are laser-focused on rent. They negotiate the base rate down to the penny, celebrate the “deal,” and move on. 

 

But here’s the truth: rent is only part of the story.

 

The silent killer for many companies isn’t the rent itself—it’s the operating expenses.

The Hidden Line Items That Add Up

Operating expenses—things like property taxes, insurance, utilities, repairs, and maintenance—don’t grab headlines. They sit quietly in the fine print of your lease and show up as monthly charges that rarely get challenged.

 

The problem? These costs often grow faster than expected. Over time, they can erode margins, throw off budgets, and create financial surprises that make your “great lease deal” a lot more expensive than you thought.

 

I’ve seen companies sign leases thinking they had predictability, only to find out later they’re covering capital improvements for the landlord, paying above-market management fees, or absorbing costs that should have been excluded. Individually, these might look like small numbers. Together, they can represent hundreds of thousands—sometimes millions—over the life of a lease.

 

Why Most Companies Miss It

Executives are busy running businesses. Very few have the time or desire to comb through a 100-page lease or compare historical expense statements line by line. Landlords know this, and that’s why operating expense clauses are rarely written in plain English.

 

It’s not that landlords are doing anything shifty—the system is simply designed to protect their interests unless you push back. And if no one’s watching closely, those small “standard” clauses quietly tip the scales.

 

How to Protect Your Company

The good news is this doesn’t have to happen. With the right strategy, you can take control of operating expenses before they drain your bottom line. Here are three practical steps:

 

  1. Negotiate exclusions up front. Don’t just focus on the rent. Make sure the lease clearly excludes things like capital improvements, landlord legal fees, and marketing costs.
  2. Demand transparency. Ask for detailed breakdowns of operating expenses each year, not just a lump-sum increase. If it feels unclear, it probably is.
  3. Audit and benchmark. Compare your expenses to similar buildings in the market, and make sure you have a tenant-friendly audit provision in your lease.

These aren’t theoretical ideas. These are strategies we’ve used with Fortune 500 companies, high-growth startups, and everything in between. The result? Millions of dollars saved simply by shining a light on overlooked expenses.

 

The Bigger Picture

Here’s what I want every executive to understand: real estate is rarely just about the rent. It’s about the total cost of occupancy—and operating expenses are a huge piece of that equation.

 

If you only focus on the base rent, you’re only focused on part of the story. But if you broaden your view, challenge the fine print, and hold landlords accountable, you create meaningful savings and protect your company’s profitability long-term.

 

That’s what great real estate strategy looks like—not just chasing the lowest rent, but uncovering the hidden costs that quietly drain your bottom line.

 

 

Frequently Asked Questions:

Q: What are operating expenses in a commercial lease?
A: Operating expenses are costs passed from the landlord to tenants to cover building operations. These can include property taxes, insurance, maintenance, utilities, and management fees.
Q: Why do operating expenses increase so much over time?
A: Many leases allow landlords to pass along rising property taxes, utilities, and even capital improvements. Without clear exclusions or regular review, these costs can escalate year over year and significantly impact your bottom line.
Q: How can I reduce or control operating expenses in my lease?
A: The best approach is proactive: negotiate exclusions before signing, request detailed annual expense statements, and benchmark your costs against similar properties. Negotiate favorable audit language which will help identify and challenge inappropriate charges.
