Site Selection and Occupancy Cost: Why Cheap Rent Is Not Cheap Occupancy
Site selection conversations in franchising center on base rent. The franchisor's real estate team has target base rent ranges for the concept. The broker presents sites with varying rent per square foot. The franchisee evaluates options partly on rent. Everyone treats base rent as the primary occupancy cost variable.
Base rent is not occupancy cost. It is the most visible component of occupancy cost, but in a NNN lease, it is not the whole story. The NNN pass-throughs — CAM, taxes, insurance — add materially to the monthly cost, and their magnitude depends on the property, not just the market.
Sites that look cheaper on base rent often look less cheap when you model total occupancy cost.
The Components of Total Occupancy Cost
Total occupancy cost in a NNN lease has four pieces:
Base rent. Negotiated, fixed for the lease term (or with scheduled escalations). This is the number that gets attention during site selection.
CAM. The tenant's pro-rata share of common area maintenance costs. Varies by property age, condition, and management. Not visible in the broker conversation. Requires looking at prior reconciliations.
Real estate taxes. The tenant's pro-rata share of property taxes. Varies by jurisdiction and assessed value. Can change significantly if the property sells or if a reassessment event occurs.
Building insurance. The landlord's property insurance premium passed through to tenants. Generally the smallest NNN component but variable depending on the landlord's insurance program.
The sum of these four components is occupancy cost. The sum is what matters for store-level P&L. The site that costs more on base rent but less on NNN may have lower total occupancy cost than the site that looks like a deal.
Why Older, Lower-Rent Properties Often Have Higher NNN
There is a consistent pattern in commercial real estate that franchisees encounter without a framework to understand it: older properties with lower base rents often have higher CAM rates than newer, higher-rent properties.
The logic is straightforward. An aging strip center built in the 1990s has:
- An aging parking lot that requires more frequent maintenance and periodic resurfacing
- Aging HVAC and rooftop systems that generate larger repair events
- Older plumbing and lighting infrastructure that requires more upkeep
- A property management fee that may be higher per dollar of controllable expenses because the management burden is greater
A newer property built in 2018 has:
- A relatively new parking lot with a predictable maintenance cycle for the first 10 to 15 years
- Modern mechanical systems with better efficiency and lower near-term repair probability
- A property management fee applied to a lower controllable expense base
The result: the 1990s strip center may offer $24 per square foot base rent with CAM of $12 to $15 per square foot. The 2018 center may offer $34 per square foot base rent with CAM of $7 to $9 per square foot. Total occupancy cost at the older property: $36 to $39 per square foot. Total occupancy cost at the newer property: $41 to $43 per square foot.
The newer property costs more on base rent. It may cost less all-in. And it probably has fewer lease negotiation battles about whether a parking lot resurfacing is capital or maintenance.
How to Evaluate Sites on Total Occupancy Cost
The comparison methodology is the same whether you are evaluating two sites or ten:
Step 1: Get three years of actual CAM reconciliations for each property. Not estimates. Actual year-end reconciliations showing the total CAM pool, the individual line items, and what tenants paid. Landlords may or may not provide this, but asking is the right starting point. If a landlord declines to share historical reconciliations for a space you are considering leasing, that is information.
Step 2: Calculate the average annual CAM per square foot. Take the three-year average of actual CAM expense allocated to the tenant suite (or comparable suite in the same building) and divide by square footage. This is your CAM estimate.
Step 3: Add taxes and insurance. Request the prior year's property tax bill and calculate the per-square-foot cost at your anticipated pro-rata share. Add the insurance pass-through from the reconciliation.
Step 4: Add base rent. You now have a total occupancy cost per square foot for each site. Compare on that basis.
Step 5: Apply the occupancy cost ratio check. Divide total annual occupancy cost by your projected gross sales for the site. Is the ratio within a range consistent with healthy unit economics for your concept?
Lease Term Quality at Lower-Cost Sites
When a lower-rent site is actually the better total occupancy cost choice, confirm that the lease terms at that site provide adequate protection. Older properties with higher maintenance needs are also more likely to generate disputes about what constitutes maintenance vs. capital, and more likely to generate large CAM pools in years when the parking lot or roof is due for attention.
At a site where the CAM rate reflects genuine maintenance intensity, negotiate:
Explicit capital exclusion. The lease should clearly state that capital improvements and capital expenditures are excluded from CAM. At an older property, define what counts as capital (useful life extension) vs. repair (restoration to working condition).
Controllable expense cap. A cap on year-over-year increases in controllable CAM expenses limits your exposure if a major maintenance event drives a large pool increase. Typical caps run 3% to 5% annually.
Management fee cap with correct base. Ensure the cap is on controllable expenses, not gross revenues. At a lower-rent property, the management fee calculated as a percentage of gross revenues versus controllable expenses produces a more dramatic overcharge relative to what the cap intends.
Audit rights. A two- to three-year audit window with the right to request backup documentation. This is standard in most commercial leases, but confirm it is present and not shortened.
CAM as a Site Selection Factor
Adding CAM analysis to the site selection process takes work, but it is the same work you will be doing annually once you are in the space. The landlord's reconciliation history is the most direct signal of what your annual occupancy cost will actually look like.
A site where the landlord provides three years of reconciliations, the CAM pool is stable and well-documented, and the NNN components are in line with your model is a lower-risk occupancy commitment than a site where the landlord cannot or will not provide historical data and the CAM estimate on the term sheet is a single number with no history behind it.
Use CAMAudit to run the reconciliation history through detection checks before signing. If the prior tenants' reconciliations show management fee overcharges or capital items billed as maintenance, you are looking at a pattern, not a one-time event. That pattern will continue after you sign unless you negotiate specific lease protections to prevent it.
