What Should You Know Before Buying a Commercial Property?

Buying a commercial property is easy to make look like a spreadsheet exercise. You have the purchase price, cap rate, rent roll, operating expenses, projected returns, and a stack of other numbers that can make a deal look very compelling. But a commercial property isn't just a collection of financial figures, and some of the most important questions you'll ask before buying one won't fit neatly into a spreadsheet.

The first question I want answered is simple: why does this property make sense?

That sounds obvious, but it's surprisingly easy to get distracted by an attractive basis or a strong-looking projected return. Before getting too deep into the underwriting, I want to understand the market, the tenants, the property's position within that market, and what could realistically change over the next several years. A property can look inexpensive because it is undervalued, but it can also look inexpensive because the market doesn't want what it has to offer.

That's where I start.

Know the Property

The physical condition of the property matters, and this is where traditional due diligence becomes critical. You need to understand the roof, HVAC, parking lot, structure, utilities, deferred maintenance, environmental conditions, access, and any major capital expenditures that could land on your balance sheet after closing.

The important distinction is between what the property costs today and what it will cost you to own it. A building with a lower purchase price isn't necessarily cheaper if you're immediately facing a major capital project, expensive repairs, or a long list of improvements needed to keep tenants happy.

The same applies to the existing leases. Understand who your tenants are, when their leases expire, what options they have, what they're paying, and what obligations you'll inherit as the new owner. A fully occupied property can look very different once you realize that several of its strongest tenants have upcoming renewal decisions.

Know the Market

Then zoom out.

What is happening around the property? Is the population growing or shrinking? What businesses are expanding nearby? What competing developments are planned? Are rents moving in a direction that supports your assumptions?

Most importantly, don't confuse current occupancy with current demand.

A property can be fully leased today and still be sitting in a market where tenants aren't particularly interested in expanding. Conversely, a property with some vacancy could be much more interesting if businesses are actively looking for space nearby and the existing supply isn't meeting that demand.

I pay close attention to what tenants are actually doing because their behavior can tell you something that historical property data can't. If multiple tenants are looking for locations in the same market, that is a different signal than simply seeing a population-growth projection on a demographic report.

Know Your Downside

Every investment has a story about how it works when everything goes according to plan. I want to know what happens when it doesn't.

What happens if a tenant leaves? What happens if leasing takes longer than expected? What happens if construction costs rise, financing changes, or the property needs more capital than anticipated? What happens if the rent growth in your underwriting never materializes?

You don't need to assume the worst-case scenario will happen, but you should understand what it would do to the investment if it did.

That's also why I think investors need to be honest about whether a deal fits their own strategy. A property can be objectively attractive and still be the wrong investment for you if it requires expertise, capital, time, or risk that you don't have available.

Know Why You're Buying It

Ultimately, I want to know what I'm buying beyond the building itself.

Am I buying reliable cash flow? A repositioning opportunity? Land with future development potential? A property in a market where tenant demand is growing? A chance to create something that doesn't exist yet?

If you can't explain the thesis in a few sentences, I think that's worth paying attention to.

The best acquisitions aren't necessarily the properties with the prettiest spreadsheets. They're the ones where the physical asset, financials, market conditions, tenant demand, and investment strategy all point in the same direction.

That's the real due diligence: not simply proving that the property is worth buying, but understanding why it should still be worth owning several years from now.

At Sytes, we're particularly interested in that last piece because tenant demand provides a different lens through which to evaluate real estate. Before buying a property, it is worth knowing not only what the property is today, but who might want to occupy it tomorrow.

The numbers tell you what you're buying.

The market tells you what it could become.
