Introduction: The Build vs. Lease Dilemma
When I first started evaluating tower site strategies for a mid-sized regional carrier, I assumed the lowest long-term cost was always the best choice. My thinking was simple: if you build your own tower, you own the asset. Eventually, the depreciation ends, and you're just collecting savings. Three budget overruns and one regulatory nightmare later, I learned a very different lesson.
In this article, I'm comparing two approaches: leasing tower space from a large REIT like SBA Communications, and self-constructing a tower from scratch. The comparison isn't about which is 'better' in a vacuum—it's about which fits specific operational realities, capital constraints, and risk tolerances. We'll look at three dimensions: balance sheet impact, operational speed, and business scale.
Balance Sheet Impact: Operating Lease vs. Capital Asset
The Assumption
I used to think building was a no-brainer for financial efficiency. The logic: lease payments are a permanent expense, while construction is a one-time cost followed by years of free use.
The Reality
When I crunch the numbers on a typical SBA Communications lease (based on their portfolio-wide average of $1,800–$2,200 per site per month for a rooftop or ground-based tower, per their 2024 filings), the picture gets more complex. Take a five-year lease term on a single site: that's roughly $108,000–$132,000 in total lease cost. Compare that to the $200,000–$350,000 we consistently see for a fully permitted, constructed, and zoned tower (our own internal project data, 2023–2024).
On paper, leasing seems more expensive. But here's where the balance sheet story changes: an operating lease like SBA's doesn't create a long-term asset or debt on your books. It's a service contract. For a carrier with a tight credit profile (like the one I worked with in early 2024—their debt-to-EBITDA was already pushing 4.5x), adding another $300k in construction loans wasn't an option without a downgrade risk. Moody's affirmed our credit rating in March 2024 (source: Moody's Investor Service), but only after we shifted to an asset-light model. A Moody's analyst specifically noted that the 'shift to operating leases reduces balance sheet risk and improves financial flexibility.' (Source: Moody's credit opinion, March 2024).
The twist: the lease looks worse on a cost-per-year basis, but if you factor in the capital cost, the risk of stranded assets (what if you need to relocate coverage?), and the credit rating implications, the lease actually wins for capital-constrained operators. Initial assumption turned upside down.
Operational Speed: The Real Cost of Delay
Time-to-Market
In my role coordinating site acquisition for a carrier, I handled 47 rush orders last year alone. Rush orders are our version of 'emergency service'—when a client's coverage deadline is 8 weeks away, and normal construction takes 12.
Here's a real example: In July 2024, a client needed a site operational for a major stadium event in 10 weeks. Self-construction timeline: 14–18 weeks (permitting alone took 6 weeks). SBA Communications already had a tower 0.3 miles away, with an existing lease agreement in place. We got the tenant equipment installed in 3 days. The lease cost was higher per month than what we'd budgeted for a build, but the alternative was a $150,000 penalty clause for missing the event coverage requirement.
The Data Point
Based on our internal data from 12 rush site deployments in 2024: SBA's existing inventory (approx. 40,000 towers nationwide per their Q4 2024 report, with a 12–18 month average occupancy ramp time) allowed deployment in 2–4 weeks, versus 14–22 weeks for self-build. When you're under a time constraint, there's no contest.
Honest limitation: This only works if SBA's tower is in the right location. In rural coverage areas, existing inventory is sparse. In those cases, self-construction or a partnership with a smaller tower company is the only option. I won't pretend SBA covers every gap—their strength is in dense metro and suburban corridors.
Business Scale: When Leasing Is Less Efficient
The Counterpoint
For a carrier with 500+ sites to deploy over a 3-year plan, the per-site lease cost adds up fast. At $25,000 per year in lease fees across 500 sites, that's $12.5 million annually—forever. A construction program of 500 towers at $275,000 each comes to $137.5 million. The break-even is around 11 years of leasing. If you're planning to operate the sites for 15+ years, building becomes the better long-term play.
But here's something I overlooked early on: you're betting on your own ability to maintain that portfolio. We lost a $2.5 million contract in 2023 because we tried to save $450k on self-maintenance instead of using SBA's included maintenance package. The client's service went down for 8 hours during a peak period, and they walked. The cost of that downtime? Priceless (but calculated at about $300k in lost revenue and a serious relationship hit).
Decision rule: If you're scaling beyond 100 sites and have the capital structure for it, self-construction makes sense. If you're under 50 sites or need to test a market, leasing from a partner like SBA is the pragmatic choice.
Conclusion: Scenario-Based Recommendations
There's no universal answer. Here's how I think about it now:
- If you're a carrier with <50 sites, tight budget, and need fast deployment: Lease from SBA. Their inventory and lease terms are designed for this scale. Don't build unless you have a specific strategic reason.
- If you're a carrier with 200+ sites and a 10-year horizon: Build your own. The lease fees will eat your budget, and you'll have the maintenance scale to justify the investment.
- If you're a carrier with 50–200 sites: This is the gray zone. Test with a lease for the first 20 sites. If the market responds, then build. The flexibility of lease-to-build conversion is a rare but valuable option—ask if SBA offers it.
One last thing: when I mention pricing (lease rates from SBA's 2024 filings, construction costs from our 2023–2024 projects), verify current rates. Costs shift with materials, interest rates, and local permitting. Always do your own diligence with the carrier's current lease schedule or a general contractor's quote.
