Definition

Capital expenditures (CapEx) are dollars spent to acquire, upgrade, or significantly extend the useful life of a physical asset. In commercial real estate, CapEx covers things like a new roof, HVAC replacement, parking lot repave, facade renovation, or building addition. CapEx items are capitalized on the balance sheet and depreciated over time, not expensed against current income.

The opposite of CapEx is operating expense (OpEx), which covers day-to-day costs like cleaning, landscaping, utilities, and minor repairs.

Tyler's Take

CapEx is where most new CRE investors get wrecked. They run a beautiful pro forma, hit their cap rate, and forget that in year four the HVAC dies or the parking lot needs to be resealed. Neither of those shows up in your operating expenses. Both of them come out of your pocket.

The rule I give every CRE Accelerator member: budget for CapEx before you close, not after. A reasonable reserve for a stabilized commercial building in Nashville is $0.15-$0.35 per square foot per year for flex and industrial, $0.25-$0.50 for retail, and $0.40-$0.75 for office. Medical office and older buildings can run even higher. If your pro forma doesn't have a replacement reserve line, the broker is lying to you or the broker doesn't know what they're doing. Either way, fix it before you bid.

The second thing I tell people: CapEx isn't bad. CapEx is how you create value. A $200k facade and signage package on a tired 15,000 SF retail building can push rents from $16/SF to $22/SF, which at a 7% cap rate adds $1.28M of value. That's a 6.4x return on your CapEx dollars. The best value-add deals in Nashville are CapEx deals where the sponsor knows exactly which dollars produce which rent increases. Random CapEx is a cost. Strategic CapEx is a wealth machine.

CapEx vs. Repairs and Maintenance

The IRS line between CapEx and repairs is fuzzy, but here's how it usually breaks down:

Capital expenditure (capitalize and depreciate): new roof, new HVAC system, full parking lot repave, structural upgrades, major building addition, elevator replacement.

Repair and maintenance (expense immediately): patching a roof leak, HVAC service call, parking lot striping or crack-fill, paint touch-ups, replacing broken light fixtures, cleaning and pest control.

The general test: if the work extends the useful life or adds value, it's CapEx. If it just keeps the property running at its current state, it's a repair.

How CapEx is Depreciated

CapEx items get capitalized on the balance sheet and depreciated over their IRS-assigned useful life: building structure (39 years commercial, 27.5 years residential), roof/HVAC/plumbing/electrical (39 years, but often accelerated via cost segregation), personal property like signage and fixtures (5-7 years), and land improvements like parking, fencing, and landscaping (15 years).

Worked Example

I buy a 20,000 SF Nashville flex building for $2.5M. My underwriting assumes:

Annual CapEx reserve = $0.25/SF x 20,000 = $5,000/year

That $5,000 goes into a reserve account. In Year 4, the HVAC units on Building A give out and replacement costs $42,000. I've saved $20,000 over the four years. The remaining $22,000 comes out of operating cash flow or my own pocket. If I hadn't built a reserve at all, the full $42,000 would have been a hit in Year 4, which could have pushed that year's cash-on-cash return into negative territory.

Strategic CapEx example: Same building, but I spend $150,000 on a new facade, LED lighting, and signage. Market rents move from $14/SF to $16/SF. My NOI increases by roughly $40,000/year. At a 7% cap rate, that's $570,000 of value created on $150,000 of spend. That's why strategic CapEx is the foundation of value-add investing.

Common Mistakes

1. Zero CapEx reserve in the pro forma. I see this constantly on broker marketing packages. Always add a reserve before underwriting.

2. Classifying CapEx as OpEx. This inflates expenses, reduces NOI, and lowers the building's appraised value. Bad for you when you refinance or sell.

3. Ignoring deferred maintenance during DD. Always get a Property Condition Assessment (PCA) on acquisitions above $1M. A PCA will flag the big CapEx items coming in the next 5-10 years.

4. Not tracking CapEx separately for tax purposes. You need a clean fixed asset schedule to claim depreciation correctly and to support cost seg work.

Frequently Asked Questions

Is CapEx tax-deductible?
Not all at once. CapEx items are capitalized and depreciated over their useful life, which means you deduct a portion each year. This is different from repairs, which are fully deductible in the year you pay them.

What's a typical CapEx reserve for commercial real estate?
In Nashville, I use $0.15-$0.35/SF/year for flex and industrial, $0.25-$0.50 for retail, and $0.40-$0.75 for office. Older or more specialized buildings run higher.

Can CapEx be passed through to tenants?
In NNN leases, landlords can often pass through CapEx reimbursements through CAM charges, though many leases cap CapEx amortization. Always check the specific lease language.

What's the difference between CapEx and TI?
TI (tenant improvements) is a specific type of CapEx tied to a particular tenant's buildout. General CapEx covers the whole building. Both get capitalized, but TI usually depreciates over the lease term.
