How Much Is My Self-Storage Business Worth? A Guide for Spanish Operators

Spain’s self-storage industry has entered a period of accelerated transformation. Since 2019, the number of facilities across the country has more than doubled, driven by a confluence of structural and behavioral shifts: rising urban density, changing lifestyles, the growth of ecommerce, and increased demand for flexible storage solutions. As a result, self-storage has evolved from a niche product into a recognized, high-margin, real estate-backed investment category.

As a consequence of this growth in demand and operational maturity, institutional investors began to take serious notice. In an environment where traditional asset classes like office and retail have struggled with structural vacancy and evolving tenant expectations, self-storage emerged as a highly attractive alternative. It offers strong fundamentals, recurring cash flow, and inflation-protected pricing — features that align well with the objectives of real estate funds, family offices, and private equity platforms. Larger operators are also consolidating market share via acquisitions of smaller, independent operators. These buyers aren’t just interested in new developments — they are seeking existing, cash-flowing assets that can be brought under centralized platforms.

This has left many independent owners wondering:

“What could my self-storage business actually be worth?”

The answer is not always obvious. Whether you own your property or operate on a leasehold basis (as many in Spain do), valuations depend on a range of factors — not just financial performance, but also lease quality, location, and the investor’s own underwriting strategy. This article offers a practical, data-supported framework to help Spanish operators understand what drives value in today’s self-storage market — and how to prepare, even if a sale isn’t on the horizon.

Understanding What Investors Are Valuing

To understand how both real estate and business operations are valued in a self-storage investment, we need to consider several common valuation methods used by investors. Each approach offers a different lens — and which one gets applied depends on who the buyer is and what kind of asset you’re selling.

EBITDA Multiples

In the Spanish self-storage market, this is one of the most commonly used valuation tools. Rather than focusing on the property, it looks at the business itself — how profitable it is, how scalable it might be, and what kind of earnings it generates. EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It’s a clean way to measure your core operating performance, excluding financing and accounting differences.

If your facility produces €300,000 in EBITDA and the buyer applies an 8x multiple, your business might be valued at €2.4 million. This method is especially popular for leasehold businesses, or for buyers looking to build a branded platform. For freehold sites or assets with strong cash flow and branding, the multiple can climb even higher. Typical ranges for leasehold-based businesses in Spain tend to fall between 5x and 10x, while freehold assets — particularly those that are mature and stabilized — can reach 12x to 20x.

Cap Rate (Capitalization Rate)

Cap rates are the go-to method when a buyer is also acquiring the property itself. They express the relationship between your property’s net operating income (NOI) and its value:

Value = NOI / Cap Rate

Think of it this way: the cap rate is the return an investor expects to earn on the asset’s income. If your site generates €250,000 in NOI and the buyer applies a 6.25% cap rate, that implies a valuation of €4 million. The lower the cap rate, the higher the value — and the more confident the buyer is in your asset’s income stream. NOI here refers to rental income minus all operating costs, excluding financing and depreciation — essentially, your property’s real cash flow.

Cap rates are more common when the buyer is a real estate investor, and especially when the facility is stabilized and owned freehold. They’re influenced by location, market maturity, asset quality, and lease structure.

Discounted Cash Flow (DCF)

DCF is a more complex approach — but very useful for assets that are still ramping up, or have room to grow. Instead of focusing only on current income, DCF looks at future performance: what cash flows will the asset generate over the next 10–15 years, and what are those cash flows worth today?

This method is typically used by institutional buyers or developers who need to underwrite risk and potential. It’s more sensitive to assumptions (like how fast occupancy will rise, or what rents will look like in 5 years), but allows for detailed, scenario-based valuation. It’s ideal for facilities that are new, under expansion, or not yet stabilized.

Price per Net Lettable Area (€/m²)

This method is more of a shorthand — used early in conversations or for comparing broad market trends. It looks at the asset’s total rentable space and assigns a value per square metre. In Spain, freehold sites in core markets may trade for €1,500–2,200/m², while leasehold deals tend to range from €400–800/m², depending on lease quality and income.

It’s quick and easy — but it ignores things like profitability, lease terms, or ramp-up status. So while it’s helpful for rough benchmarking, serious buyers will always move on to a more income-based method.

With these tools in mind, let’s look at how ownership structure impacts valuation.

Leaseholds vs. Freeholds: What Investors Really See

In Spain, many self-storage businesses operate on leasehold terms — that is, the operator rents the space rather than owning it. This model has enabled fast growth in urban areas, where buying real estate outright is often cost-prohibitive. And while freehold assets are typically favored by institutional investors — who benefit from long-term control, capital appreciation, and refinancing options — well-structured leaseholds are still attractive under the right conditions.

Leaseholds play a critical role in the Spanish market. When structured correctly, they allow access to prime urban locations that would otherwise be too expensive to acquire, enable faster expansion across a city without tying up capital in real estate, and support high-margin operations, particularly in dense areas with strong pricing power. It’s worth noting that not all NOI is valued equally. A compact, high-performing site in central Madrid generating €150,000 in NOI may be more valuable than a larger site on the outskirts producing €250,000 — especially when long-term positioning and brand visibility are taken into account. But the key lies in the lease structure.

Institutional buyers have very specific requirements: they typically look for a minimum lease length of 15 years, with at least 10 years remaining at the time of sale; assignability, so the lease can be transferred to a new owner; predictable rent escalations and no major restrictions on operations or modifications; and ideally, an option to purchase the property in the future. If your site has only 4 or 5 years left on the lease and no renewal or purchase option, it will likely be non-investable for most professional buyers. The risk of eviction, rent hikes, or operating restrictions is simply too high, and it makes cash flow projections unreliable. These sites may be sellable to private buyers or operators, but not at institutional valuations.

How Lease Terms Affect Valuation — Even When Using EBITDA Multiples

While leasehold businesses are most commonly valued using EBITDA multiples in Spain, some investors still reference cap rates to benchmark risk — especially when comparing leasehold and freehold returns side by side.

The reasoning is simple: the shorter or weaker the lease, the greater the uncertainty about income continuity, rent terms, and operational control. That uncertainty leads investors to demand a higher return — whether expressed as a higher cap rate or a lower EBITDA multiple — which reduces the valuation.

So while cap rates may not be the primary method used for leasehold valuations, they can still be a helpful way to illustrate the impact of lease terms on perceived risk and pricing.

Example:

  • Freehold, Madrid, €200,000 NOI, 6.0% cap → €3.33 million
  • Leasehold, excellent terms, 10+ years remaining, option to buy, 8.0% cap → €2.5 million
  • Leasehold, weak lease, 5 years remaining, no purchase option, 9.5% cap → €2.1 million

These cap rates loosely translate to implied EBITDA multiples — with the strong leasehold falling somewhere around 8–10x, and the weaker lease closer to 6x or lower.

In short: lease quality has a direct and material impact on valuation — no matter which method is applied.

Know Your Value, Even If You’re Not Selling

Even if you have no intention of selling, understanding your business’s value helps you make smarter strategic decisions. Knowing how buyers evaluate your site — and what methods they’re likely to apply — gives you more control when negotiating, expanding, or optimizing your facility. It can guide you in:

Renegotiating your lease terms Planning site expansions or upgrades Benchmarking against future acquisition offers Preparing clean, investor-ready financials

Final Thoughts

Spain’s self-storage market is no longer an emerging niche — it’s a rapidly maturing investment class. Buyers are active, capital is available, and valuations are increasingly driven by professional standards. For smaller operators, this shift highlights the importance of understanding how their business is valued — not just to assess potential offers, but to confidently participate in a market that is increasingly shaped by larger, better-informed players.

Whether you’re considering a sale now or simply planning for the future, understanding what drives value — and how investors think — is essential.

With the right lease structure, operational performance, and occupancy profile, even a small facility can command strong interest and serious offers.

AI and the Future of Digital Marketing

A Quick Guide For Self-Storage Operators

The way people search for businesses is starting to change—and it’s not a subtle shift. AI tools like ChatGPT, Google Gemini, and DeepSeek are beginning to shape how customers ask for recommendations online. Instead of browsing a list of results or clicking on ads, users increasingly expect direct, curated suggestions. And when that happens, only a handful of businesses will be recommended.

For self-storage operators, this could change the rules of digital marketing. While Google Ads and SEO still matter today, there’s a clear need to prepare for a future in which your facility may need to earn a place in a single AI-generated answer, not just on a search results page.

This guide explains what’s happening, where we’re headed, and what you can start doing—this week—to make sure your business stays visible as AI-driven search becomes more mainstream. The goal isn’t only to gain the trust of AI tools—it’s also to train and educate them about your business, your services, and why you’re a relevant choice for the customers they’re helping.

What’s Changing

In a traditional search, a customer looking for storage in Valencia might type “self-storage Valencia” into Google. They’d see a mix of paid ads, a map with local listings, and some organic search results.

Now imagine someone asking an AI assistant: “Where’s the best self-storage facility near me?” Instead of showing a dozen options, the assistant gives one or two names. The AI isn’t just pulling from keywords—it’s weighing reviews, web presence, business relevance, and public signals.

This kind of search doesn’t reward whoever spends the most on ads. It rewards businesses that are credible, well-reviewed, and clearly described across the web.

Why You Can’t Just Pay for Placement (Yet)

As of now, you can’t buy visibility in ChatGPT or DeepSeek the way you can on Google. OpenAI, Google, and others are still figuring out how to introduce advertising into their AI models. That might change soon—but for now, inclusion is earned, not bought.

That’s exactly why this moment matters. The early days of AI search present a unique opportunity: to build the kind of online presence and reputation that makes your business one of the few chosen by the AI. Once paid placements become the norm, the competition will be steeper and more expensive.

Why This Matters for Self-Storage

To understand how AI might change discovery, it’s helpful to first consider how people currently find storage services in Spain. Right now, Google Search and Google Maps remain the most widely used tools. Most customers search directly for “trasteros en [city]” or similar terms, often comparing options based on map location, ratings, and opening hours.

However, platforms like Idealista, Fotocasa, Wallapop, and the newly launched Trasterone may play a much larger role in the near future. While Idealista and Fotocasa are focused on property listings and Wallapop on classifieds, Trasterone is specifically built to serve the self-storage industry. If these platforms start integrating AI features—or if AI models begin pulling data from them—your visibility may depend on whether and how you’re listed there.

Self-storage is a local, need-based service. Customers don’t spend weeks researching. They do a quick search, compare a few options, and make a decision.

AI tools aim to simplify that even further: instead of offering a list, they just tell the user what to do. If your facility isn’t the one being recommended, you may not even be considered.

And because these tools rely on more than just your website—they pull from reviews, listings, directory sites, and even blog content—your broader online footprint becomes just as important as your home page. Maintaining a blog on your own website can support this effort. A simple strategy: publish one short post per month answering a real customer question or explaining a key service (e.g., “How much storage space do I need?” or “Short-term vs long-term storage—what’s the difference?”). This builds trust and helps AI models understand the specific value your business offers.

Five Things You Can Do Now

1. Make Your Site Easier to Understand

AI systems need clear, structured information. If your website runs on WordPress, you can use plugins like Yoast or Rank Math to implement schema.org markup for local business data. If not, speak to your web developer about adding this directly to your site’s code.

Your website should clearly state:

  • What services you offer
  • Where you’re located
  • What unit sizes and pricing are available
  • What makes your facility stand out

Review your homepage and service pages to ensure clarity, accuracy, and structure. Keep the language simple, natural, and customer-focused—remember, it’s not only your potential customer reading it, but also the AI interpreting it.

2. Improve Your Online Reputation

AI recommendations are influenced heavily by customer reviews and public sentiment. Now’s the time to:

  • Ask your recent happy customers to leave a review—prioritizing Google Maps or Trustpilot depending on what’s most trusted by your audience. Use a direct link from your Google Business Profile to make it easy.
  • Set up polite follow-up emails after sign-up to request a review.
  • Claim and update your business information across relevant directories like Google Maps, Apple Maps, QDQ.com, and Páginas Amarillas. Make sure your hours, contact info, and service descriptions are consistent.

Respond monthly to reviews across all platforms. This consistent engagement shows AI that your business is active and customer-oriented.

3. Monitor How AI Mentions Your Business

Try it yourself. Ask ChatGPT, Gemini, or Bing Copilot: “What’s the best self-storage in [your city]?”

  • Does your name appear?
  • Does it return an answer at all?

Create a simple spreadsheet and track this monthly. Log which tools mention your business and what they say. Over time, this becomes your AI visibility dashboard.

4. Don’t Hide Your Prices

Many operators hesitate to publish pricing, either to avoid scaring off potential customers or because they worry about competition. But in an AI-driven search landscape, pricing transparency will be a key trust factor. If AI tools can’t understand what your service costs—or if another facility is more open about pricing—they’re more likely to recommend that business. Even listing a starting price or price range helps position you as more trustworthy and complete.

5. Don’t Abandon Google Ads—Yet

PPC campaigns still work, and they’re still necessary. But begin reallocating around 10% of your marketing budget toward AI-readiness. If you don’t have the expertise in-house, consider working with a specialist or agency to ensure that each area is handled professionally—especially when it comes to content creation, technical improvements, and online reputation management. These investments can yield a strong return by improving visibility and trust in both AI and traditional channels.

Focus your efforts on:

  • Hiring a content writer to improve your site’s tone and clarity—e.g., writing a blog post that answers “How much storage do I need?” or rewriting your homepage with more natural, customer-focused language
  • Implementing a reputation strategy: monitor and respond to reviews, optimize your Google Business profile and other listings, and consider external help to strengthen your online perception
  • Testing ad placements on Microsoft Bing, which already integrates AI features

The sooner you begin strengthening your digital presence, the better positioned you’ll be when AI platforms begin offering sponsored placements.

When Will This All Take Shape?

There’s no fixed timeline, but the direction is clear. Based on recent reports and statements from industry leaders:

  • 2024–2026: AI-powered answers begin influencing decisions. According to The Times, retail traffic from AI tools increased tenfold in the second half of 2024. PPC still dominates for most local services.
  • 2026–2028: Sponsored AI recommendations begin to appear. Competition increases.
  • 2028–2030: AI-driven search becomes the dominant or preferred method for local discovery. Businesses without a strong AI presence begin to lose visibility.

Final Thoughts

You don’t need to guess where things are heading. The tools your customers use to search are changing. The way they discover businesses is changing. And the cost of visibility is about to shift dramatically.

But this isn’t about abandoning what works—it’s about adding what’s coming.

Start here:

  • Review and simplify your website content
  • Identify areas where expert help—content, technical SEO, or reviews—could save you time and improve results,
  • Add structured data (schema markup),
  • Ask for fresh customer reviews this month,
  • Check how AI tools describe your business,
  • Allocate around 10% of your marketing budget to future-focused visibility efforts

Operators who act early won’t just adapt to AI search—they’ll lead it.
