Storage units rarely work as an investment for most people

Storage units can generate steady rental income, but the math usually does not work in your favour unless you own the land outright or buy at a significant discount. The typical investor buys a unit for $50,000 to $150,000, rents it for $100 to $300 per month, and faces ongoing costs: property taxes, insurance, maintenance, vacancy periods, and management fees if you hire someone to handle tenants. After those expenses, your annual return often falls between 4 and 7 percent — lower than stock market averages and with far more work involved.

The real money in storage is made by the company that owns the facility, not the individual unit owner. They control pricing across the whole property, negotiate bulk insurance rates, and spread maintenance costs across hundreds of units. A single unit owner pays retail prices for everything and carries the full risk if a tenant stops paying or the market softens.

Key Takeaways

  • Most storage unit investments return 4 to 7 percent annually after expenses, which is lower than historical stock market returns and requires active management.
  • Your actual costs include property taxes, insurance, maintenance, potential vacancy gaps, and either your own time or a management company's fees.
  • Storage unit values depend heavily on local market conditions and facility occupancy rates, which can shift quickly if new facilities open nearby.
  • Buying a unit at a facility you do not own means the parent company can raise common area fees, change tenant rules, or sell the property without your consent.
  • Storage units work better as a way to store your own belongings than as a path to building wealth.

How the money actually breaks down

A $100,000 storage unit renting for $150 per month brings in $1,800 per year in gross income. From that, subtract property taxes (varies by location but often $1,200 to $2,400 annually), insurance ($400 to $800 per year), and a reserve for repairs and maintenance ($500 to $1,000 per year). You are left with $200 to $700 in net income — a 0.2 to 0.7 percent return on your investment before accounting for the time you spend managing the tenant, handling complaints, or hiring someone else to do it.

If you finance the unit with a mortgage, your lender will want 20 to 30 percent down and will charge interest that eats further into returns. A $70,000 loan at 7 percent interest costs roughly $5,000 per year in interest alone during the first years, which exceeds your entire net income.

Vacancy is the silent killer. Even in a strong market, units sit empty between tenants. A 10 percent vacancy rate (one month empty per year) cuts your income by $180 on a $150-per-month unit. In weaker markets or during economic downturns, vacancy can reach 20 to 30 percent.

Location and market risk matter more than you might think

Storage unit demand is local and fragile. A new facility opening two blocks away can drop occupancy rates across the neighbourhood by 15 to 25 percent within months. Tenants are price-sensitive and will move their belongings to save $20 per month. Unlike residential real estate, where location and scarcity create lasting value, storage is a commodity — renters care only about price, access, and cleanliness.

Economic downturns hit storage hard. When people lose jobs or move for work, they often sell their stored belongings rather than pay monthly fees. During the 2008 recession, occupancy rates at many facilities fell below 50 percent. Your $150-per-month income can vanish overnight.

Conversely, in a booming market with low vacancy and rising rents, a storage unit can perform well for a few years. But that performance is temporary and depends on conditions you cannot control.

Ownership structure changes what you actually own

Most individual storage unit investors do not own the land or the building. They own a single unit within a facility operated by a larger company. That company sets the rules: they can raise common area fees (which you pass to tenants or absorb yourself), change tenant policies, increase insurance requirements, or sell the entire property. When a facility sells, the new owner often raises rents across the board, which can price out your tenants and leave your unit vacant.

If you own the land and building outright, the math improves because you eliminate the facility operator's cut and common area fees. But that requires $500,000 to $2 million in capital and the ability to manage a multi-unit operation — a different business entirely from buying a single unit.

What actually makes storage units worth buying

Storage units make sense in two situations: you need the space yourself, or you have capital sitting idle and want a low-risk, hands-off income stream despite the modest return.

If you own a unit and use it to store your own belongings, you are not trying to generate income — you are paying for a service. That is a straightforward cost-benefit decision: does the monthly fee match what you would pay elsewhere, and do you actually need the space? That is a reasonable use case and has nothing to do with investment returns.

If you have $100,000 in savings earning 0.5 percent in a bank account, a storage unit returning 5 percent looks attractive by comparison, even if it requires occasional maintenance calls and tenant management. The return is still modest, but it beats cash. This works only if you have the capital to absorb a loss if the market shifts or a tenant defaults.

Comparing storage units to other investments

A diversified stock index fund has returned roughly 10 percent annually over the past 50 years, with no tenant management, no vacancy risk, and no property taxes. A rental house in a strong market can return 8 to 12 percent after expenses and often appreciates in value over time. A storage unit typically returns 4 to 7 percent with higher management burden and no appreciation.

Bonds and Treasury securities currently yield 4 to 5 percent with zero management and no risk of tenant default. Real estate investment trusts (REITs) that own storage facilities let you invest in the sector without buying a single unit — you get the facility operator's returns, which are higher than a unit owner's, with complete liquidity.

If your goal is to build wealth, storage units are a slower path than most alternatives. If your goal is to park money somewhere safer than a savings account, they work, but so do bonds with less hassle.

The hidden costs people forget

Tenant turnover costs money. Cleaning between tenants, minor repairs, and the time spent showing the unit to prospects add up. If a tenant leaves without paying their final month, you have a loss. If a tenant damages the unit, you pay for repairs before renting it again.

Financing costs are often underestimated. A mortgage on a storage unit carries a higher interest rate than a residential mortgage because the lender sees it as higher risk. You might pay 7 to 8 percent instead of 5 to 6 percent, which significantly reduces your net return.

Selling a storage unit takes time and carries transaction costs. Real estate agents typically charge 5 to 6 percent commission. If you need to exit quickly, you may have to discount the price. Stock investments can be sold in seconds with minimal cost.

Frequently Asked Questions

Can I make money if I buy a storage unit and rent it out?

Yes, but the return is usually 4 to 7 percent after expenses, which is lower than stock market averages. You will also spend time managing the tenant, handling maintenance, and dealing with potential vacancy periods. The income is steady but modest.

What happens if my tenant stops paying rent?

You have to go through eviction, which takes weeks or months depending on your state and costs money in legal fees. During that time, you are not collecting rent. Once the unit is empty, you have to clean it and find a new tenant, which can take another month or more.

Is a storage unit a good hedge against inflation?

Partially. You can raise rents as inflation rises, so your income keeps pace. However, your expenses (property taxes, insurance, maintenance) also rise with inflation. The net effect is that your return stays roughly the same in real terms, not higher.

Should I buy a storage unit if I already own rental properties?

Only if you have excess capital and want to diversify away from residential real estate. A storage unit is simpler to manage than a rental house but returns less. If you have time and informed in residential rentals, that is usually a better use of your money.

What if the storage facility I own a unit in gets sold?

The new owner can change policies, raise common area fees, and adjust tenant rules. Your unit's value may drop if the new owner raises fees or lowers the quality of the facility. You have no control over these decisions because you own a unit, not the property itself.
