How to Use List Stacking to Find the Best Off-Market Self Storage Leads

In a crowded real estate space where good deals seem harder to come by every day, self-storage investing continues to stand out for its stability, scalability, and strong return on investment. But here’s the hard truth: most of the best opportunities never hit LoopNet, Crexi, or any broker email blast. They’re off-market. And if you want to win at self-storage investing, mastering the art of finding these hidden gems is essential.

At StorageLife, we specialize in teaching off-market strategies through our self-storage coaching program led by Cameron Barsanti, who has closed 17 deals using this exact playbook. One of our most powerful tools? List stacking.

This blog will walk you through what list stacking is, how to use it, and why it’s one of the highest-leverage strategies you can use to find quality off-market self-storage deals.

What Is List Stacking?

List stacking is the process of combining and filtering multiple data sources to prioritize leads that meet very specific investment criteria. Instead of calling or mailing to a giant, random list of self-storage owners, you strategically “stack” lists together to isolate high-quality, high-probability opportunities.

Think of it like putting multiple layers of filters on your lead pipeline until only the best, most likely-to-sell owners are left.

In the world of self-storage investing, this might mean stacking lists such as:

• Facilities with no website or outdated websites

• Mom-and-pop ownership (not part of REITs or big operators)

• Located in secondary or tertiary markets

• Properties over a certain larger square footage (trophy assets)

• Properties with low Google reviews or minimal online presence 

When you combine these filters, you start uncovering leads that most investors overlook—and that’s where the spread lives.

Why List Stacking Beats the Broker Game

Here’s the reality: if a deal is on a public listing site or with a self-storage broker list, it’s probably already been picked over. You’re now competing with dozens of other buyers, and cap rates are compressed.

But if you find a facility through list stacking and cold outreach, you’re talking directly to the owner. No broker fees. No bidding wars. Just you, the seller, and the opportunity to build rapport.

This is exactly how Cameron Barsanti and the StorageLife team have been able to scale a portfolio using a direct-to-seller approach.

As he often says:

"The lifeline of a self-storage investor hinges on one thing only, and that is the ability to find opportunity."

How to Start List Stacking (Step by Step)

If you want to learn how to start a self-storage business and go beyond surface-level education, list stacking is where your sourcing begins.

Here’s how to do it:

Step 1: Start With Your Core List

Begin with a general list of self-storage facilities. This can come from:

• Google Maps

• Data scraping tools (like OutScraper or GMap Extractor)

• Local property records

• Third-party providers like Reonomy, ListSource, or PropStream

Make sure your list includes:

• Facility name

• Owner name (if available)

• Address

• Website (if any)

• Number of units or square footage

• Google reviews

Step 2: Apply Filters

Now, layer in your filters. Here are a few that Cameron recommends:

• No website: High indicator of mom-and-pop ownership

• Low review count: Likely not optimized or marketed

• Rural or secondary market: Less competitive buyer pool

• Generic email (e.g., Gmail or Yahoo): Less likely to be institutional

• No property management software: Another signal of non-professional operators

This is your first stack.

Step 3: Rank by Priority

Take your stacked list and rank it:

• Tier 1: Trophy Assets – Large square footage, no website, mom-and-pop owner, growing market

• Tier 2: Solid Leads – Medium-sized, outdated website, potential upside

• Tier 3: Monitor – Facilities with some professionalization but still worth checking in

This allows your team or self-storage virtual assistants to focus efforts where they matter most.

Tools That Make List Stacking Easier

You don’t need to be a data scientist to get results. Here are some tools we use at StorageLife to streamline list stacking:

• Google Sheets or Airtable: For sorting, tagging, and filtering leads

• OutScraper or GMap Extractor: To pull data from Google Maps

• CallRail: For tracking and recording cold calls

• Mojo Dialer: Power dialer for cold outreach

• VA support: Our trained VAs handle skip tracing and call scheduling

With the right tools, even small teams can handle high-volume lead sorting and outreach.

Why Trophy Assets Matter

Cameron often emphasizes the importance of focusing on "trophy assets."

These are facilities that:

• Are 40,000+ square feet

• Operate without a website

• Are run by aging owners

• Have visible upside in pricing or operations

These are the facilities that don’t just offer solid cash flow, they build long-term wealth.

By using list stacking to identify and rank trophy assets, StorageLife students spend less time chasing dead leads and more time nurturing the relationships that matter.

Turning a List Into a Deal: The Follow-Up Game

Finding leads is step one. Closing deals? That comes down to relentless follow-up.

This is where most investors drop the ball. At StorageLife, we teach our members to:

• Follow up with top leads every 90 days (minimum)

• Build real rapport through calls, emails, and self-storage marketing letters

• Use consistent branding across all outreach

• Never assume a seller is uninterested until they sell to someone else

We’ve seen trophy asset owners respond after years of contact. It’s not uncommon. But if you don’t stay top-of-mind, you’ll never be the first person they think of when it’s time to sell.

Common Mistakes in List Stacking

If you're new to self-storage investing, watch out for these traps:

• Over-filtering: You want quality, not perfection. Too many filters might leave you with no leads.

• Failing to track: Without KPIs, it’s impossible to know what’s working.

• Lack of delegation: If you’re doing it all yourself, you’ll burn out. Train your VAs.

• Skipping the phone: Email and mail matter, but a phone call builds trust faster.

• One-and-done mindset: Follow-up is everything.

Why This Strategy Wins in Every Market

When the market is hot, direct-to-owner deals offer better spreads. When it’s cold, owners are more motivated. In every case, list stacking gives you leverage.

You’re not just reacting to what’s available - you’re creating your own opportunities.

This is how you:

• Get better self-storage cap rate by state

• Sidestep broker fees

• Understand how to analyze a self storage deal in context

• Control your deal flow instead of chasing it

Whether you're seeking your first facility or growing through self-storage syndication, list stacking is the foundation.

Final Thoughts: Stop Searching, Start Stacking

Your next great deal isn’t hiding. It’s buried in your own data.
