How to Compare Industrial Lease Proposals Side by Side

In recent posts, we've spent a good deal of time on individual lease components—escalation clauses, yard space, mezzanines, and the like. But one question we get asked more than almost any other from business owners in Orange County goes something like this: "I've got two proposals in front of me. How do I actually compare them?" It sounds straightforward, but in our experience, this is exactly where tenants leave serious money on the table. A lease proposal is not a price tag. It's a financial model disguised as a one-page document, and if you don't know how to read it that way, you're essentially buying a car by looking only at the monthly payment while ignoring the interest rate, term length, and what happens when the transmission fails.

This guide is designed to give you the analytical framework we use every day when helping tenants evaluate competing offers. We'll walk through the key variables, show you real math, and help you build an apples-to-apples comparison that actually means something.

Start With Total Occupancy Cost, Not Base Rent

First and foremost, stop comparing base rent. We know that sounds counterintuitive—after all, it's the biggest number on the page—but base rent alone tells you almost nothing about which lease is a better deal. What you need to calculate is Total Occupancy Cost (TOC) over the full lease term. This means adding up every dollar you'll pay to occupy that building, from day one to the final month.

Let's take a quick look at a simplified example. Suppose you're comparing two 10,000 square foot industrial spaces in Anaheim. Proposal A comes in at $1.25 per square foot per month (NNN) on a 36-month term with 3% annual escalations. Proposal B is quoted at $1.35 per square foot per month (NNN) on a 60-month term with 2% annual escalations, but includes four months of free rent and a $25,000 tenant improvement allowance.

At first glance, Proposal A looks cheaper. But let's run the numbers.

Proposal A — 36-Month Total Cost:

• Months 1–12: $1.25 × 10,000 × 12 = $150,000
• Months 13–24: $1.2875 × 10,000 × 12 = $154,500
• Months 25–36: $1.3261 × 10,000 × 12 = $159,132
• Total Base Rent: $463,632
• No free rent, no TI allowance
• Net Total Cost: $463,632

Proposal B — 60-Month Total Cost:

• Months 1–4: $0 (free rent) = $0
• Months 5–12: $1.35 × 10,000 × 8 = $108,000
• Year 2: $1.377 × 10,000 × 12 = $165,240
• Year 3: $1.4045 × 10,000 × 12 = $168,540
• Year 4: $1.4326 × 10,000 × 12 = $171,912
• Year 5: $1.4612 × 10,000 × 12 = $175,344
• Total Base Rent: $789,036
• Less $25,000 TI allowance
• Net Total Cost: $764,036

Now, Proposal B is clearly more expensive over the full term—but it also covers 60 months versus 36. To compare fairly, you need to calculate the effective monthly cost for each. Proposal A runs roughly $12,878 per month. Proposal B runs roughly $12,734 per month after factoring in free rent and the TI allowance. Suddenly, Proposal B is actually the lower-cost option on a monthly basis, and it locks you in longer at a lower effective rate. That's the kind of insight that only shows up when you do the full math.

Normalize the Lease Structure Before You Compare

Secondly, lease proposals are rarely structured the same way, and landlords know this works in their favor. One proposal might be quoted on a gross basis (landlord pays operating expenses), while another is NNN (you pay property taxes, insurance, and maintenance). In Orange County industrial parks, NNN charges typically run anywhere from $0.15 to $0.40 per square foot per month depending on the age of the building, the property tax base, and whether the landlord recently refinanced or sold the asset—all of which can affect your pass-through costs significantly.

In our experience, a gross-to-NNN conversion error is one of the most common mistakes tenants make during lease comparison. If you're evaluating a $1.50 gross lease against a $1.20 NNN lease, you need to add the estimated NNN charges to the $1.20 figure before comparing. If NNN runs $0.28 per square foot in that submarket, your real cost is $1.48—effectively the same deal, with very different risk profiles. Under a gross lease, the landlord absorbs operating cost increases. Under NNN, those increases pass directly to you.

Evaluate the Non-Financial Terms as Financial Variables

Thirdly—and this is where most tenants completely drop the ball—the non-financial terms of a lease have real dollar value, and they belong in your comparison. We're talking about things like renewal option rights, early termination clauses, assignment and sublease rights, and co-tenancy provisions.

Consider renewal options. A lease that gives you two 3-year renewal options at a fixed rent cap of 95% of fair market value is worth real money in a market where rents trend upward over time. In contrast, a lease with no renewal option or one that resets fully to market rate leaves your business exposed at the end of the term. We've seen tenants in Fullerton and Garden Grove get effectively priced out of buildings they've operated in for over a decade simply because they didn't negotiate a meaningful renewal structure the first time around.

Similarly, an early termination clause—even with a penalty—gives your business flexibility that has genuine financial value if your headcount, equipment needs, or operational model changes during a multi-year term. Some follow the mantra that you should always take the shortest lease possible to preserve flexibility. Others prefer the security and concession advantages that come with a longer commitment. Both approaches have merit depending on your business trajectory, and the right answer lives in the details of each specific proposal.

Build a Side-by-Side Comparison Matrix

Once you've gathered all the variables—base rent, escalations, lease term, free rent, TI allowance, NNN charges, renewal options, and key non-financial terms—put everything into a side-by-side matrix. We recommend organizing it in three tiers: Year 1 effective cost, total cost over the full term, and qualitative factors ranked by importance to your operation.

For the qualitative tier, assign a dollar value or a weighted score to things like building clear height, dock doors versus grade-level access, power availability, parking ratio, and yard access. A 24-foot clear height versus a 28-foot clear height might mean the difference between single-stack and double-stack racking—and that operational difference could be worth $50,000 or more in shelving and logistics efficiency annually for the right user. Don't leave those variables floating in the air as vague preferences. Quantify them.

The Hidden Variable Most Tenants Ignore

Bottom line: the variable that consistently separates sophisticated tenants from reactive ones is landlord quality and building condition. Two proposals can look nearly identical on paper and deliver completely different experiences in practice. A landlord who is slow to respond to HVAC failures, roof leaks, or dock leveler breakdowns is costing your business money every single day those issues go unresolved. In our decades of experience working with landlords across Orange County, we've developed a clear sense of who operates professionally and who doesn't—and that intelligence is genuinely worth something when you're choosing between two otherwise comparable deals.

At absolute minimum, you should immediately consult with an experienced industrial tenant rep broker before signing any lease—ideally before you even respond to a proposal. The framework we've outlined here is a starting point, but the nuances of each negotiation, each landlord relationship, and each building's specific characteristics require professional eyes on the full picture. Give us a call and we'll walk through your proposals together, run the numbers, and help you make a decision you'll be confident in for years to come.
