Self-Storage Investing Deal Structures Explained (For Partnerships and Solo Investors)

When you start diving into self-storage investing, one of the first questions that naturally comes up is: how do I fund a deal? Whether you're partnering up or going solo, understanding how to structure a deal is a critical skill for success in self-storage as an investment. At StorageLife, our mission is to guide investors through the practical, profitable, and proven paths in this business, and this guide is designed to demystify exactly that.

Why Deal Structure Matters

Deal structure is more than a financial formula. It's the foundation of trust, roles, risk allocation, and returns between partners—or between you and your lender. While the funding may seem like the hardest part when you're starting out, the truth is that finding the right deal is what matters most. Once you have a strong deal, the structure can be built around it.

At StorageLife, we emphasize this with all our self-storage mentorship students: get good at finding deals, and the money will follow.

Basic Deal Structures: Solo vs. Partnership

If you're going solo, your structure will be simple: you're bringing the capital, you're signing the debt, you're doing the work. The risk is higher, but so is the reward.

In a partnership structure, things generally break down into three categories:

1. Capital Partner – brings the money.

2. Sweat Equity Partner – operates, manages, and improves the deal.

3. Deal Finder – finds and locks up the opportunity (often overlooked but hugely valuable).

Understanding who brings what, and compensating fairly, is the first step toward a sustainable partnership. In our self-storage mastermind, we’ve seen countless variations of these partnerships, and the best ones are rooted in clear expectations and fair equity splits.

The 50/50 Starting Point

A common and simple model many of our members use is a 50/50 structure:

• Both parties bring 50% of the capital.

• Both share in responsibilities, operations, and decision-making.

It’s clean, equitable, and easy to execute. This approach is especially effective for first-time buyers learning how to start a self-storage business.

However, if one party does more (e.g., finds the deal, runs operations, guarantees the loan), they might warrant a larger share, even if capital is 50/50. The value of experience and operational labor should not be underestimated.

Adjusting for Roles and Responsibilities

Let’s say you find a deal, lock it up, negotiate great terms, and bring it to a partner who will fund it and maybe help run it. Here's a general structure we’ve seen work well (below is shown only as an example; equity splits are ultimately made based on what makes sense and agreed upon by all partners):

• 3%–10% equity for finding the deal.

• 15%–30% equity for operating and managing.

• Remaining equity based on capital contributed.

This kind of hybrid model rewards skill and hustle, not just cash. It’s especially useful if you’re learning how to invest in self-storage without a lot of money up front.

Using Promissory Notes to Raise Capital

If you’re solo or just short on cash, one creative way to fund your portion of a deal is through promissory notes:

• Borrow from family, friends, or private lenders.

• Offer interest (typically 6–10%) with a balloon payment.

• Use seller-financed deals where banks don’t trace your debt.

This method has helped many of our self-storage mentor clients close their first deals with minimal capital out of pocket. Just be mindful: if you’re using a bank loan, that debt will count against your qualification ratios.

Seller Financing Structures

Seller financing is one of the most powerful tools in self-storage investing. It often allows you to:

• Put less money down.

• Avoid bank qualification hassles.

• Negotiate flexible terms.

We recommend offering three options to sellers:

1. Conventional Loan Offer – Lower price, higher down.

2. 5-Year Seller Finance – Mid-price, modest interest.

3. 10-Year Seller Finance – Higher price, minimal down, stretched terms.

We’ve had incredible success closing deals using this three-offer method. It allows sellers to choose based on their needs (price vs. terms) while allowing you to craft a structure that boosts your self-storage return on investment.

Syndication vs. Joint Venture

Syndication is ideal for larger deals ($1M+ equity raise). Here’s a quick breakdown:

Syndication:

• You (GP) raise money from passive investors (LPs).

• GP usually keeps 25–40% equity.

• LPs are hands-off.

• Requires legal compliance (SEC regulations).

Joint Venture:

• All partners must be active.

• Easier setup, fewer legal costs.

• Great for 2–5 person teams.

While StorageLife is potentially expanding into self-storage syndication, we often encourage new investors to start with JVs for simplicity.

Tips for Structuring Fair Partnerships

1. Define all roles upfront. Who finds the deal? Who signs the loan? Who manages the asset?

2. Use a written agreement. Always formalize terms with an attorney.

3. Set expectations. What are the goals, timelines, and exit strategies?

4. Reassess over time. Equity doesn’t always reflect effort forever—adjust as needed.

If you’re learning how to analyze a self-storage deal, you'll quickly understand how structure impacts everything from cash flow to taxes to decision-making.

Real-World Example from StorageLife

One of our students secured a $2.4M facility. They structured it like this:

• Seller financing: 20% down, 5.5% interest, 20-year amortization, 2-year balloon.

• Raised capital through promissory notes at 8%.

• Gave 10% equity to the person who brought the deal.

• Retained 80% ownership split between two partners.

That deal had $3M+ in equity from day one. This is the kind of opportunity available with a well-structured deal and a good team.

Final Thoughts

Deal structures are not one-size-fits-all. They should be dynamic, fair, and reflective of value, not just dollars. Whether you’re a solo operator or part of a team, your structure should support growth, accountability, and profitability.

At StorageLife, we teach our students that you don’t need to have all the money to get started, you need the knowledge and the hustle. Learn how to structure a deal, and suddenly, self-storage investing becomes accessible.
