How to Invest in Industrial Outdoor Storage: Step-by-Step

By Tyler Cauble, Founder of The Cauble Group · ~10 min read · Updated May 2026

If you're brand new to industrial outdoor storage and want the asset class basics first — the four types, typical cap rates, market dynamics — start with our pillar guide on what is industrial outdoor storage. This article picks up where that guide leaves off: the actual step-by-step playbook for buying your first IOS deal.

You've decided IOS is the asset class. You've heard the cap rates are decent, the management is easy, and the demand is structural. Now you want to actually go buy one.

Here's the seven-step playbook I use whenever I'm helping investors close their first IOS deal:

The 7-Step IOS Investment Playbook

1. Pick a market you can drive in 90 minutes

2. Build a working underwriting model with real comps

3. Source deals (mostly off-market)

4. Line up financing before you write your first LOI

5. Tour properties and submit aggressive offers

6. Run real due diligence — especially zoning and environmental

7. Operate the asset (or hire it out right)

Most investors who fail at IOS fail because they skip steps 2, 4, or 6. The rest of this article walks through each step in the order you should actually execute them.

I cover the same framework in this hour-long workshop if you'd rather watch:

Why IOS Is a Solid First Industrial Investment

Before we get into the steps, a quick gut check: IOS is arguably the most beginner-friendly commercial real estate asset class. Here's why.

The math is simple. You don't have to underwrite tenant improvements, HVAC replacements, or roof reserves. There's almost no building. Your operating expenses are property taxes, insurance, security, basic maintenance (lights, fencing, paving repairs), and management. That's it.

The deals are smaller. You can buy a 2-3 acre IOS yard in many secondary markets for $500K to $2M. That's accessible with SBA financing or a small group of co-investors. Compare that to a Class A warehouse at $10M+ and the entry barrier is dramatically lower.

The cash flow is real. A well-purchased IOS deal can throw off 8-12% cash-on-cash returns in year one. With rent growth and management improvements, that often climbs to 15-20% by year three.

The downside is bounded. Worst case, you own a piece of industrial land in a logistics corridor. Land value tends to hold or appreciate, especially as cities zone out new IOS. Even if IOS demand softened, the land typically has alternative industrial uses.

Step 1: Pick a Market You Can Drive in 90 Minutes

Don't try to invest in IOS across 12 metros. Pick one — ideally within 90 minutes of where you live or work — and become the most knowledgeable IOS buyer in that market.

Three criteria for picking a market:

• Logistics infrastructure. A major port, intermodal rail terminal, interstate junction, or distribution corridor. This is what creates demand for trailer parking, container storage, and equipment yards.
• Active construction. Growing metros with single-family and commercial construction pipelines drive demand for equipment yards.
• Restrictive zoning trend. Markets where cities are actively tightening IOS zoning — meaning existing properties are becoming irreplaceable.

The top IOS markets in the country right now include the Inland Empire (CA), Dallas-Fort Worth, Atlanta, Houston, Phoenix, Nashville, Charlotte, Memphis, Indianapolis, and the New York / New Jersey port complex. But honestly, almost any growing metro with industrial infrastructure works.

Step 2: Build Your Underwriting Model

You need a model before you tour your first property. If you're underwriting on the fly while you're walking a yard, you'll fall in love with the wrong deal and pass on the right one.

The minimum your model needs:

• In-place NOI based on actual rent rolls (not the seller's pro forma)
• Market rent comparison showing what tenants would pay at today's market rates
• Operating expense breakdown including property taxes after the post-sale reassessment (this is critical and often skipped)
• Capital reserve for fencing, paving, lighting, and security upgrades
• Financing assumptions with realistic interest rates and DSCR
• Exit cap rate 50-100 bps higher than going-in cap (be conservative)
• Sensitivity table for vacancy, rent growth, and exit cap

If you don't have your own model, our free commercial real estate underwriting calculator handles all of this. Use it. Adjust the cap rate and operating expense assumptions to match IOS (lower opex than warehouses, similar cap rate range).

Step 3: Source Deals (Mostly Off-Market)

The good IOS deals are almost never on Crexi or LoopNet. The listed properties tend to be overpriced trophy assets or distressed deals that have been on the market for months. You need an off-market sourcing strategy.

Search by zoning, not asset class

Pull every industrial-zoned listing in your market. Read the descriptions. Look for keywords like "contractor's yard," "outside storage permitted," "industrial land," "I-2 zoning," or "fenced lot." These are IOS deals that aren't marketed as IOS.

Drive the corridors

Find your market's truck routes, rail corridors, and port-adjacent industrial pockets. Drive them. Note every fenced yard that looks owner-operated, under-managed, or has a weathered "For Sale by Owner" sign. Pull ownership from the county assessor's records. Send a letter. Make a call.

Build broker relationships

Industrial brokers who specialize in IOS are rare. Most industrial brokers only do warehouses. Find the ones who actually live in IOS, take them to lunch, and explain exactly what you're looking for (size, market, deal profile). They'll bring you off-market deals because the institutional buyers can't move fast enough on smaller properties.

Watch for distress signals

An IOS owner who's retiring, divorcing, or dealing with an estate is often a motivated seller. So is an owner whose primary trucking tenant just went out of business. Build a network of attorneys, accountants, and brokers who can tip you to these situations.

Step 4: Line Up Financing Before Your First LOI

This is where most first-time IOS investors stub their toe. They find a deal, write an LOI, get under contract — and then realize their bank doesn't lend on land-and-improvements without a building.

Best lender options for IOS:

• SBA 504 loans. Up to 90% LTV on owner-occupied IOS (if you're using part of the yard for your own business). 10% down with the rest financed over 25 years at competitive rates.
• Life insurance companies. Sometimes the best non-recourse option for stabilized IOS at $3M+. Lower leverage (60-65% LTV) but excellent rates and terms.
• Regional banks with industrial experience. Local banks that already lend on industrial real estate often have appetite for IOS. The relationship matters here.
• Private debt funds. For value-add or transitional IOS deals where conventional financing doesn't work. Higher rates but faster close.

Get pre-qualified before you start touring. Have your team in place: lender, attorney, environmental consultant, title company, and ideally a property manager you've vetted. The first deal takes the longest; by deal three, you'll have a process.

Step 5: Tour and Submit Aggressive Offers

When you find a deal that hits your underwriting box, be ready to move. Good IOS deals — especially off-market — get scooped up in days, not weeks.

On the tour, look for:

• Truck access. Can a 53-foot Class 8 tractor-trailer get in and out without backing across a major road? Drive it in your own truck first. If it feels tight in a pickup, it's unworkable for an 18-wheeler.
• Paving and drainage condition. Repaving 3 acres can run $200K+. Check for cracking, ponding, and runoff issues.
• Fencing. Chain link costs $30-$50 per linear foot. Wrought iron is 2-3x that. Note the condition.
• Power and water. If you have any service buildings or you're planning to add some, confirm utility capacity.
• Existing tenant quality. Walk the yard. Look at the equipment, the maintenance, the security. Are these the kind of tenants you want?

Make your offer based on your underwriting, not the asking price. If your number is below ask, explain why with hard data (comp rents, market cap rates, deferred maintenance). Most IOS sellers don't have other buyers at the table — they'll engage with a well-justified offer.

Step 6: Run Real Due Diligence (Especially Zoning + Environmental)

This is the make-or-break step. The DD on an IOS deal looks different from a warehouse or retail deal. Three things matter most:

Zoning verification

Get a written zoning verification letter from the city planner confirming that outdoor storage is a permitted use on the parcel. If the use is "legal non-conforming" (grandfathered), confirm exactly what events would extinguish the use — fire, vacancy, abandonment — and how long the vacancy clock runs. This is non-negotiable. Skip this and you could be buying a yard that the city can shut down in 5 years.

Phase I environmental study

Trucks leak. Equipment leaks. If the yard has operated for 20+ years, soil contamination is a real possibility. Always order a Phase I. If anything's flagged, order a Phase II (soil sampling). Remediation costs can range from $50K to seven figures depending on the contamination. Better to find out before closing.

Stormwater permit + drainage

Paved or graveled IOS yards generate significant stormwater runoff. Many jurisdictions have tightened stormwater requirements over the past 5 years. Bringing an older yard into compliance can cost $50K to $500K. Verify the current stormwater permit and whether any upgrades are required.

Tenant estoppels

If you're inheriting existing tenants, get signed estoppel certificates confirming lease terms, rent paid through date, and any disputes. Verbal handshakes from the seller mean nothing.

Step 7: Operate the Asset (or Hire It Out Right)

If you're hands-on and only have one yard, IOS is one of the easiest commercial properties to self-manage. You're collecting rent from 5-30 tenants, doing basic maintenance (light bulbs, paving touch-ups, occasional security calls), and gradually pushing rents to market.

If you have multiple yards or you're scaling, hire a property manager who specializes in industrial — NOT residential. Residential property managers will get eaten alive by trucking tenants. Look for managers who already handle IOS or industrial assets in your market.

The two operational priorities that drive returns:

• Annual rent increases. Build them into every new lease (3-4% per year minimum, or CPI). Push existing tenants toward market on renewal.
• Lease structure improvements. Convert month-to-month tenants to 1-3 year leases. Move from gross to NNN. Each conversion increases NOI and decreases your risk.

Common First-Deal Mistakes to Avoid

Five mistakes I see new IOS investors make over and over:

1. Trusting the seller's pro forma. Underwrite to in-place NOI, not what the seller says rents could be. Adjust to market rent in your own model — don't pay for it today.

2. Skipping the zoning verification letter. "The seller said it was legal" is not enough. Get it in writing from the city.

3. Underestimating property taxes post-sale. Assessors are catching up to IOS values. Use the post-sale assessment in your model, not the seller's old tax bill.

4. Forgetting environmental due diligence. Always Phase I. If flagged, Phase II. Lenders will require this anyway.

5. Hiring a residential property manager. Just don't. Trucking and equipment tenants need a manager who speaks their language.

Next Steps

If you've made it this far, you have the framework. Here's the order I'd take from here:

1. Read the IOS pillar guide for asset class fundamentals if you haven't yet.
2. Pick your market.
3. Use the free underwriting calculator to build your model.
4. Start sourcing deals (drive the corridors, build broker relationships, search by zoning).
5. When you find a deal, run it through DD and submit.
