I Picked the Wrong Tower Partner Twice. Here’s My 5-Step Checklist for Choosing a Site Infrastructure Provider (2025 Edition)

Who This Checklist Is For (And the Mistake I Made)

If you’re a network operator or enterprise leasing wireless tower space, you’ve got options. SBA Communications, American Tower, Crown Castle—and a handful of smaller players. The natural instinct is to compare lease rates per site. I did that. Twice. And both times? I ended up paying way more than I saved.

My first big mistake was in 2021. I was responsible for securing rooftop sites for a regional carrier. I went with the lowest quote. Thought I was being clever. The lease was $200 cheaper per month than the SBA quote. But the hidden costs ate that saving in six months. The second time was in 2023—a small cell deployment. I ignored network design flexibility. That mistake cost us $3,200 in rework plus a two-week delay.

So here’s the checklist I use now. It’s a 5-step guide for evaluating any tower REIT—SBA Communications included. Use it before you sign a lease.

Step 1: Map Your Coverage Gap (Not Just the Lowest Price)

What to do: List the specific locations where you need coverage. Don't start with pricing. Start with where your subscribers are dropping calls or where your data speeds are crap.

The check: Can the provider cover those gaps with their existing portfolio? Or will you need to fund a new build?

I once approved a lease for a site that looked perfect on paper. Cheap, too. But the tower was 300 meters from where I actually needed coverage. The signal strength was marginal. We ended up spending $1,200 on a booster that barely helped. (Should mention: I should have done a drive test first.)

Step 2: Audit the Lease for 'Hidden' Cost Triggers

This is where most people screw up. The headline price per site is easy to compare. The real cost is in the clauses.

What to check:

• Escape clauses for the landlord: Can they kick you out with 90 days' notice? If so, your investment in equipment is at risk. SBA and other REITs usually have long-term leases (10-20 years) that give you stability. Smaller landlords might not.
• Escalation triggers: Are increases tied to CPI? A fixed percentage? A flat dollar amount? CPI-linked is generally safer. In 2022, a lease with a 3% flat escalation cost us $1,500 more than the CPI-linked alternative over 24 months.
• Modification fees: If you need to swap out a radio or antenna (and you will), what's the charge? Some contracts charge a flat fee. Others charge a percentage of the new equipment value. That can get ugly.

Step 3: Check the 'Network Design Flexibility' (The One Everyone Skips)

This is the step I missed in 2023. You don't just need a site. You need a site that can handle your future equipment.

What to ask:

• What’s the tower’s load capacity? If you plan to add 5G equipment later, can it handle the weight?
• Is there room for small cells or additional antennas? Or are you getting a single, fixed lease for one piece of gear?
• Can you co-locate with another carrier? If your lease forbids it, you're stuck.

I once signed a lease on a rooftop site that seemed ideal. Three months later, I needed to swap a radio for a slightly heavier model. The landlord hit me with a $2,000 engineering review fee. Plus a two-week delay. (Oh, and the small cell deployment I mentioned? The tower was at capacity. We had to build a new pole 50 meters away. That was the $3,200 mistake.)

Step 4: Run a Long-Term Total Cost of Ownership (TCO) Model

Don't compare year 1 costs. Compare years 1-10.

How to do it:

1. Start with the base lease rate.
2. Add the annual escalation (use CPI average of 3% if unknown).
3. Add the modification budget (plan for one modification every 24 months).
4. Add the expected admin and compliance fees for your market.
5. Compare total projected spend over 5 years.

Here’s the thing about SBA Communications (SBAC): their portfolio is national. They have investment-grade credit ratings (S&P affirmed them as of early 2025). That stability matters. A lease with a less stable landlord might be cheaper today, but if they default or sell the tower to a new owner—and the new owner doubles your rent—you're in a bad spot.

Step 5: Verify Their 'Support' Is Actually Supportive

Technical support isn't just about fixing a broken antenna. It’s about speed of response when you need to modify a site or get a lease amendment.

What to request:

• Ask for a contact person for site modifications. Not a general support line. A real person.
• Check their average time for lease amendments. I've seen quotes from 5 days to 6 weeks. The 6-week guys cost you money while you wait.
• Ask about their small cell deployment process. A standard SBA rooftop lease might get you a response in 3 business days. A smaller provider? Might be a month.

Wrapping Up (And the Mistake I Almost Made Again)

I almost went with the cheapest option again last quarter. I had my checklist. The cheap quote was $150 less per month than SBA's. But when I ran the TCO model and included the hidden risks (modification fees, stability, network design limits), the cheap option was actually $2,100 more over 5 years.

Bottom line: Use this checklist before you sign. And don't just compare the monthly rate. The total cost of a bad lease is way more than you think.

(Disclaimer: I'm a network deployment manager, not a financial advisor. The decision to lease a tower is yours based on your specific needs and budget. My checklist is based on mistakes I made in the field—your experience might differ, especially if you're working with smaller, local providers.)
