Storage units are real estate you can own outright, not just rent month-to-month

Buying a storage unit means purchasing the physical structure and the land it sits on, or buying into a storage facility as an investment property. This is different from renting a unit from a facility owner. When you buy, you own the asset, can rent it out to tenants, and build equity—but you also handle maintenance, property taxes, insurance, and vacancy periods yourself.

Most people buy storage units through one of three routes: purchasing a single unit at an existing facility (rare and usually requires the facility owner's consent), buying a multi-unit storage facility as a commercial property, or investing in a storage facility through a real estate investment trust (REIT). The path you take depends on your budget, whether you want to manage tenants yourself, and how much capital you have upfront.

Key Takeaways

  • Buying a storage unit requires commercial real estate financing, which typically demands 20 to 30 percent down and a business plan showing expected rental income.
  • Single-unit purchases at existing facilities are uncommon because most storage owners do not sell individual units; you are more likely to buy an entire facility or a portfolio of units.
  • Storage facility purchases are evaluated on net operating income (NOI) and cap rate, not on the number of units alone, so you will need to understand the facility's current occupancy and rental rates.
  • Property taxes, insurance, maintenance reserves, and property management fees typically consume 40 to 50 percent of gross rental income before you see profit.
  • REITs offer storage ownership without direct management but give you no control over operations or the ability to deduct losses against other income.

Buying a single storage unit at an existing facility

Buying one unit at a facility where hundreds of others are rented is almost never an option. Storage facility owners operate as a single business entity and do not typically subdivide ownership. If a facility does allow unit sales, the owner usually retains management control, collects rent from your tenants, takes a percentage, and handles maintenance—which means you are not really buying an asset, you are buying a revenue stream with limited control.

If you find a facility willing to sell you a unit, you will need a commercial mortgage, which requires 20 to 30 percent down, proof of business income or tax returns, and a personal may provide. The lender will want to see the facility's occupancy history, rental rates, and lease terms. Even then, most lenders will not finance a single unit because the risk is too high and the loan amount too small to justify underwriting costs.

Buying an entire storage facility as a commercial property

This is the more common path for storage ownership. You purchase the land, buildings, and all units as a single commercial real estate asset. Facilities range from 50 units to over 500, and prices vary widely based on location, occupancy rate, age of the buildings, and local market demand. A 100-unit facility in a secondary market might cost $2 million to $4 million; the same size in a major metro area could be $6 million or more.

To buy a facility, you will work with a commercial real estate broker who specializes in storage properties. They will provide a Proforma—a financial projection showing current occupancy, average rent per unit, operating expenses, and projected net operating income (NOI). The NOI is what lenders care about most. If a facility generates $200,000 in annual NOI and you buy it for $2 million, your cap rate is 10 percent. Lenders typically want to see a cap rate of 6 to 8 percent or higher, depending on the market and the facility's condition.

Commercial financing for storage facilities usually requires 25 to 30 percent down, a 15 to 20 year loan term, and personal tax returns for the past two years. The lender will order an appraisal and a Phase I environmental assessment. You will also need a business plan showing how you intend to manage the facility, what rent increases you project, and how you will handle maintenance and tenant turnover.

Understanding cap rate, NOI, and what lenders actually look at

Net Operating Income (NOI) is the money left after you subtract operating expenses from gross rental income. Operating expenses include property taxes, insurance, utilities, maintenance, repairs, property management (whether you hire someone or value your own time), and a reserve for vacancies and unexpected costs. NOI does not include debt service—the mortgage payment itself.

Cap rate (capitalization rate) is NOI divided by purchase price. If a facility generates $150,000 in NOI and costs $2 million, the cap rate is 7.5 percent. A higher cap rate means more income relative to the price you pay. Lenders use cap rate to assess risk: a facility with a 6 percent cap rate in a stable market is less risky than one with a 10 percent cap rate in a declining area, because the higher return suggests the market is pricing in more uncertainty.

When you explore for a commercial loan, the lender will stress-test the numbers. They will assume occupancy drops by 10 to 15 percent, explore a 3 to 5 percent annual expense increase, and recalculate NOI. If the facility still generates enough income to cover the debt service with a safety margin (usually 1.25 times the annual payment), the loan is approvable. If not, you will need a larger down payment or the lender will decline.

Operating expenses and what eats into your profit

Storage facilities look profitable on paper until you account for the real costs of running one. Property taxes on a $2 million facility in most states run $15,000 to $40,000 per year, depending on the jurisdiction. Insurance (property, liability, and loss of rents coverage) typically costs $8,000 to $20,000 annually. Utilities—even for a mostly unheated facility—run $5,000 to $15,000 per year.

Maintenance and repairs are the wildcard. A roof replacement, HVAC failure, or parking lot reseal can cost $20,000 to $100,000 in a single year. Most experienced owners set aside 10 to 15 percent of gross income as a maintenance reserve. If your facility generates $400,000 in gross rent, you should reserve $40,000 to $60,000 annually for repairs and replacements.

If you hire a property manager, expect to pay 5 to 10 percent of gross income. If you manage it yourself, you are trading your time for that percentage. Tenant turnover, late payments, and evictions also cost money. A realistic operating expense ratio for a storage facility is 40 to 50 percent of gross income, which means a facility generating $400,000 in rent will have $160,000 to $200,000 in expenses before you pay the mortgage.

Financing options and down payment requirements

Commercial banks, life insurance companies, and specialized commercial lenders all finance storage facilities. Banks typically offer the lowest rates but the strictest underwriting. Life insurance companies (like Prudential or MetLife) move slower but are more flexible on occupancy rates and property condition. Specialized commercial lenders focus on storage and understand the business model, but charge higher rates.

Down payments range from 20 to 30 percent. A $2 million facility requires $400,000 to $600,000 down. Loan terms are typically 15 to 20 years, with interest rates currently ranging from 6 to 8 percent depending on the lender, your credit, and the facility's performance. Some lenders offer adjustable-rate mortgages (ARMs) with lower initial rates but higher risk if rates rise.

You will also need to budget for closing costs: appraisal ($3,000 to $5,000), title search and insurance ($1,000 to $2,000), environmental assessment ($2,000 to $5,000), legal fees ($2,000 to $5,000), and loan origination fees (1 to 2 percent of the loan amount). Total closing costs typically run 2 to 4 percent of the purchase price.

Investing in storage through a REIT

A Real Estate Investment Trust (REIT) is a company that owns and operates real estate properties, including storage facilities. When you buy shares in a storage REIT, you own a fractional stake in a portfolio of facilities. Major storage REITs include Public Storage, Extra Space Storage, and Life Storage. You can buy shares through any brokerage account, with no down payment requirement beyond the share price.

REITs offer liquidity—you can sell your shares whenever the market is open—and professional management. You do not handle tenants, maintenance, or property taxes. However, you also have no control over operations, cannot deduct losses against other income, and pay income tax on dividends at ordinary rates (not capital gains rates). REITs are best for investors who want storage exposure without the work and capital requirements of direct ownership.

Finding storage facilities for sale and working with brokers

Storage facilities are sold through commercial real estate brokers, not on MLS sites like residential properties. Brokers who specialize in storage include CBRE, Cushman & Wakefield, and smaller regional firms. You can search for available facilities through CoStar (a commercial real estate database), but access usually requires a broker relationship or a subscription.

When you contact a broker, be clear about your budget, the geographic area you are interested in, and whether you want a stabilized facility (already full with established tenants) or a value-add opportunity (partially occupied, with room to raise rents). Brokers will send you an offering memorandum, which includes the facility's financials, tenant list, lease terms, and property details. Review this carefully with an accountant or financial advisor before proceeding.

Once you find a facility you want to buy, you will make an offer, conduct due diligence (which includes a Phase I environmental assessment, a property inspection, and a review of all leases and contracts), and close within 30 to 60 days. The seller will usually require a deposit of 1 to 3 percent of the purchase price to show good faith.

Frequently Asked Questions

Can I buy a storage unit without a commercial mortgage?

Yes, if you have cash. However, most buyers finance through a commercial lender because it preserves capital for maintenance reserves and other investments. If you pay all cash, you still need to account for property taxes, insurance, and maintenance in your return calculations.

What is a good cap rate for a storage facility?

Cap rates vary by market and facility condition. In strong markets, 5 to 7 percent is typical for stabilized facilities. In secondary markets or for value-add properties, 8 to 12 percent is common. Higher cap rates suggest either more risk or more upside potential. Compare the cap rate to other investments and to the facility's specific circumstances.

How long does it take to close on a storage facility purchase?

Typically 30 to 60 days from offer to closing. This includes due diligence, appraisal, environmental assessment, and lender underwriting. If the lender requests additional documentation or the environmental assessment uncovers issues, closing can extend to 90 days or more.

Do I need a real estate license to buy and sell storage facilities?

No. You need a real estate license only if you are acting as a broker or agent for other people. Buying and selling property for your own investment does not require a license. However, hiring a broker to represent you is standard practice and helps you find deals and navigate the transaction.

What happens if occupancy drops after I buy the facility?

Your income drops, but your fixed costs (property taxes, insurance, debt service) remain the same. This is why lenders stress-test the numbers and require a safety margin. If occupancy falls below what the lender assumed, you may struggle to cover the mortgage. This is a real risk, which is why location, market demand, and the facility's condition matter so much.
