Capital Expenditures (CapEx): The Bill That Shows Up After You Close

What it is

Capital expenditures — CapEx — are the big-ticket items that keep a building standing and functioning: a new roof, a parking lot overlay, an HVAC replacement, a facade or storefront upgrade. They're different from operating expenses like landscaping, trash, or pest control. Operating expenses happen every month. CapEx happens every several years, and when it lands, it's a real check — not a line item you can shrug off.

Every building has a CapEx clock running in the background, whether or not anyone's talking about it.

How it plays out in retail net lease

Here's how I explain it to clients. In a true net lease, the tenant typically covers taxes, insurance, and common area maintenance. That part is clean and easy to like. But roof and structural repairs are usually still the landlord's responsibility — even in deals marketed as "absolute net." Don't assume. Read the lease.

So the CapEx conversation in net lease isn't about whether these costs exist. They exist in every deal, every asset class. The real question is who's responsible for them, and when they're likely to come due.

I've watched buyers fall in love with a cap rate and never ask about roof age. Then two years in, they're staring at a bid for a full roof replacement and wondering why nobody warned them. Nobody hid it — nobody asked.

Retail boxes, strip centers, and QSR pads take a beating differently than office or industrial space does. Parking lots crack under weather and daily traffic. Flat retail roofs don't last forever. Rooftop HVAC units sit exposed to the elements and tend to need replacement sooner than people expect. None of this means retail is a bad asset class — it just means physical buildings cost money to keep physical. The mistake isn't that CapEx exists. The mistake is pretending it doesn't.

What to watch for

• Who actually pays for roof and structure — verify it in the lease, don't take "NNN" at face value
• The age of the roof, parking lot, and major mechanical systems — ask for maintenance records, not guesses
• Whether the seller can produce a reserve study, engineering report, or service history
• Remaining lease term measured against the age of the building's systems — a short lease paired with an aging roof is worth a real conversation
• Deferred maintenance quietly labeled "cosmetic" in the marketing package

How to use it to your advantage

Ask for the records upfront, before you're deep into a deal emotionally. A seller who can hand you a recent roof inspection, HVAC service history, or an active reserve fund is telling you they've run the property like a business. That's a good sign. A seller who gets vague or defensive when you ask about the roof is also telling you something.

Build a maintenance and replacement reserve into how you underwrite, even informally. I tell people not to just look at the cap rate on day one — look at what the building is going to ask of you in five or ten years. That's not pessimism. It's accounting for the whole picture instead of half of it.

Then use what you find as leverage. A roof near the end of its useful life is a legitimate reason to renegotiate price, ask for a seller credit, or adjust timing. It's a far better conversation to have before closing than after.

Best case, worst case

Best case:

• The property has newer systems, documented records, and a lease that shifts more of the ongoing burden to the tenant
• You walked in with eyes open, budgeted for the eventual replacement, and it never catches you off guard
• Well-maintained buildings tend to hold tenants and retain value more consistently over time

Worst case:

• A major system fails or needs replacement shortly after closing, and it wasn't priced into your purchase
• You're funding a significant repair out of pocket while debt service keeps going
• A short lease term collides with an aging building right as you're trying to negotiate renewal — from a weaker position
