The biggest mistake in buying a self-storage facility is treating the loan like a home loan. Lenders assess these purchases as commercial property, so they look closely at the income the facility earns, not just at you.
At TM Finance Group, we are a female-led, team-driven broker based in Gippsland. We often talk with local buyers who have found a facility and want to move quickly. A little preparation before you make an offer can save a lot of back and forth later.
How Does Commercial Property Finance for Self-Storage Work?
A commercial property loan for self-storage is a loan secured against the facility, and the lender will usually assess both the property and the business income it produces. Terms, deposits and pricing differ from residential lending and vary between lenders.
Expect a lender to ask for the facility's trading history, occupancy levels and rental income. They will also look at your own financial position. Compared with a home loan, the deposit is often larger, and the interest rate may be higher, depending on the lender and the property. Our commercial loans page explains how we approach these purchases, and our business loans page covers funding for the operating side.
The trade-off is that a larger deposit protects your loan to value ratio (LVR) but ties up cash you may need for running the business after settlement.
What Not to Do: Skip the Valuation Conversation
Do not agree on a price before you understand how a lender will value the facility. A commercial property valuation is often based on the income the facility earns, so a price built on optimistic projections may not be matched by the lender's figure.
If the valuation comes in below the contract price, you need to cover the gap with your own funds. That can derail a purchase at a late stage.
Consider a buyer who is looking at a facility with strong occupancy and plans to buy it with a deposit of 30% of the price. The seller's price assumes occupancy will rise. The buyer speaks to a broker before signing, and the broker explains that the lender may value the facility on current income only. The buyer negotiates a price closer to what the figures support, and adds a finance clause to the contract. The valuation arrives in line with the price, and the loan proceeds without the buyer needing extra cash at settlement.

Should You Choose a Variable or Fixed Interest Rate?
A variable interest rate moves with the lender's pricing, while a fixed interest rate locks in repayments for an agreed period. Which suits you depends on how tightly the facility's cash flow can absorb a rise in repayments.
Fixing gives certainty, which helps when you are budgeting around a facility's income. The trade-off is that you may face break costs if you repay or refinance early, and fixed loans can limit extra repayments. Variable loans are usually more flexible, but your repayments can rise.
Some lenders let you split a loan between fixed and variable portions. Ask your broker about this, along with any redraw feature and flexible repayment options.
Why Loan Structure Matters More Than the Headline Rate
The loan structure often affects your cash flow more than a small difference in rate. Structure covers the loan term, whether you pay interest only for a time, and how the loan is secured.
Here is an illustrative example using a rate of 6.75% p.a. Say you borrow $1,000,000 over 25 years on principal and interest. The monthly repayment would be about $6,910. If you pay interest only at the same rate, the monthly repayment would be about $5,625. Interest only looks lighter, but you are not reducing the debt. When principal and interest begins, repayments are calculated over the shorter remaining term, so they will be higher than the figures above. Your actual rate will depend on your deposit, the lender and the property. You can test your own numbers with a calculator, and our borrowing capacity page is a good place to start.
A lender may also ask for extra security, such as a residential property you own. That can help the loan get approved, but it puts that property at risk if the business struggles.
What If the Facility Needs Upgrades or Expansion?
If the facility needs new units or building work, a commercial construction loan can fund the build in stages. A staged loan, often called progressive drawdown, releases money as work is completed, so you pay interest only on what you have drawn.
The trade-off is more paperwork. Lenders typically want plans, costings and a builder's contract, and inspections may be needed before each payment. Our construction loans page explains the process. If you also plan to buy equipment such as access gates or security systems, our asset and equipment finance options may suit that part of the plan.
Can You Buy Self-Storage Through a Self-Managed Super Fund or Trust?
Some buyers hold commercial property through a trust, company or self-managed super fund (SMSF), and each structure has different lending and tax implications.
An SMSF can borrow only through a limited recourse borrowing arrangement. Since 10 August 2026, that kind of borrowing is limited to business real property, so whether a facility qualifies depends on how it is used. Get SMSF, tax and legal advice before committing, as tax outcomes depend on your circumstances.
Lenders usually have their own rules about which structures they accept and what guarantees they require. Raising this early means we can match you to lenders who are comfortable with your set-up, rather than finding out halfway through an application.
Why Use a Broker for Self-Storage Finance?
A broker can compare commercial loan options from our panel of lenders and present your purchase in the way each lender assesses it. That matters because self-storage sits between property and business, and lenders vary in how they view it.
A broker does not remove the need for your own due diligence. You still need your accountant and solicitor involved. If you already hold a commercial loan, a loan health check can show whether your current structure still suits you.
Call one of our team or book an appointment at a time that works for you. We will talk through your plans for the facility and what a lender is likely to want to see.
Frequently Asked Questions
How does a lender assess a self-storage purchase?
Lenders usually look at the property and the income the facility earns, including occupancy and trading history. They will also review your own financial position.
Should I choose a fixed or variable interest rate?
A fixed rate gives repayment certainty but may involve break costs and limits on extra repayments. A variable rate is usually more flexible but repayments can rise.
Can I fund upgrades or new units on a facility?
A commercial construction loan can fund building work in stages through progressive drawdown. Lenders typically ask for plans, costings and a builder's contract.
Why does the valuation matter before I sign?
The lender's valuation may be based on current income, and it can differ from the contract price. If it is lower, you may need to cover the gap yourself.
