Self-Build vs. Lease: A Cost Analyst’s Hard-Learned Lessons
In my first year (2017) as a procurement manager for a regional wireless carrier, I made the classic mistake: I assumed building our own towers would always be cheaper than leasing from a REIT like SBA Communications. I didn't verify the full lifecycle costs. Turned out I was wrong. Twice.
That error cost roughly $890,000 in redo expenses plus a 6-month delay on a network expansion project. Now I maintain our team’s due diligence checklist to prevent others from repeating my errors. Here’s what I’ve learned about SBA Communications, its lease pricing, and the S&P Global Ratings that matter.
What We’re Comparing: Building Your Own Tower vs. Leasing from SBA
Most buyers focus on the monthly lease price and completely miss the hidden costs of self-build: land acquisition, zoning approval, structural engineering, maintenance, and power backup. The question everyone asks is “What’s the lease rate?” The question they should ask is “What’s NOT included in that rate?”
I’ve learned to ask “what’s NOT included” before “what’s the price.” The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end. That’s the transparency trust principle.
Dimension 1: Upfront Capital vs. Operational Expense
Self-Build: You need $250,000–$400,000 per tower (land, permits, materials, labor). That’s cash out the door before you even attach an antenna.
SBA Lease: Zero upfront capital. Monthly rent covers the tower, maintenance, and often includes escalation clauses tied to CPI. As of Q4 2024, SBA’s average annual cash lease revenue per site was approximately $22,000 per tenant (based on their 10-K). For a multi-tenant tower, SBA collects from multiple carriers, but your lease is priced per tenant.
What I mean is that when you self-build, you’re tying up capital that could be used for spectrum licenses or customer acquisition. The “cheaper” option isn’t just about the sticker price—it’s about the opportunity cost.
Dimension 2: Time to Market
Self-Build: 12–18 months from site selection to commercial operation. I once ordered 5 towers with local zoning variances we couldn’t get. Checked it myself, approved it, processed it. We caught the error when the municipality denied permits. $200,000 wasted, credibility damaged.
SBA Lease: 3–6 months. SBA already owns the land, has zoning, and the tower is standing. You just need to install your equipment. The speed difference alone can shift a year’s revenue.
Is the premium option worth it? Sometimes. Depends on context. For dense urban coverage where speed is critical, leasing from SBA is a no-brainer. For rural macro sites with long timelines, self-build might still make sense.
Dimension 3: Flexibility and Scalability
Self-Build: You own the asset. You can modify it, exit it, or sell it. But you’re locked into one location. If the market shifts, you’re stuck with a tower that may not be leaseable to other carriers.
SBA Lease: You can adjust lease terms every 5–10 years, or walk away at the end of the term. SBA handles the maintenance and property taxes. But here’s something vendors won’t tell you: lease renewal negotiations can include rent increases of 10–15% if you need to expand capacity. The first quote is almost never the final price for ongoing relationships.
What most people don’t realize is that “standard turnaround” for lease negotiations often includes buffer time that SBA uses to manage its portfolio. The question isn’t whether you’ll get a renewal. It’s at what price.
Dimension 4: Credit Risk and Ratings
Self-Build: Your risk is your own balance sheet. If your company hits a rough patch, you still have to maintain those towers.
SBA Lease: You’re leasing from a company rated BBB- with stable outlook by S&P Global Ratings (as of January 2025). That’s investment grade. SBA’s large-scale portfolio with national coverage and long-term contracts with Verizon, T-Mobile, and Dish means they have predictable cash flows. A BBB- rating means they’re unlikely to go bankrupt and leave you without a tower.
But don’t assume a high rating means no risk. SBA’s debt is approximately 5.5x EBITDA (as of Q3 2024). That’s manageable, but interest rate hikes could pressure their ability to invest in new sites or lower rents.
“What most people don’t realize is that ‘investment grade’ doesn’t mean ‘no escalation.’ SBA has to keep pace with inflation, so your lease will likely have annual escalators of 2–3%.”
Which One Should You Choose?
After three years of studying SBA’s portfolio and making my own mistakes, here’s my scenario-based advice:
- Choose Self-Build if: You need a unique tower height or design that SBA can’t offer, you have 18+ months to deploy, and you can finance the capital expenditure without choking your growth. Also, if you plan to lease excess capacity to other carriers, you could become a mini-REIT yourself.
- Choose SBA Lease if: Speed is critical (3–6 months), you want to avoid upfront capital, or you lack internal expertise in tower maintenance. This is the choice for 80% of regional carriers I’ve worked with.
One exception: I’ve seen carriers assume “same specifications” meant identical performance across SBA and a self-build. Didn’t verify. Turned out each had slightly different loading capacity. Always ask for a structural analysis before signing.
Period.
The Bottom Line on Transparency
The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end. SBA’s lease agreements are fairly standard in the industry, but I’ve seen hidden costs like “roof site surcharges” or “generator maintenance fees” surprise buyers. I learned never to assume the proof represents the final product after receiving a batch that looked nothing like what we approved.
As of March 2025, SBA Communications remains a reliable partner for wireless carriers. The average lease price of ~$22,000/year per tenant is competitive when you factor in the avoided capital cost and the speed of deployment. But don’t take my word for it—check S&P Global Ratings’ latest report and run your own TCO model. And please, ask “what’s NOT included” before you ask “what’s the price.” Simple.
