Self storage loans: lender types and how your loan gets sized

The main loan types compared

The right lender depends less on rate than on the deal's shape: its size, whether the facility is stabilized, how long you plan to hold, and whether you can sign a personal guarantee. The table is a buyer's summary of how each source usually behaves. Every point is negotiable with some lender, so read it as a map of what to ask, not a promise of what you will get.

Banks and credit unions

Local and regional banks are a natural first call on smaller acquisitions because they can underwrite the borrower as well as the property. Expect them to look at your net worth, liquidity and other real estate alongside the facility's NOI, and to ask for a personal guarantee. Bank examiners treat mini-storage as non-owner-occupied commercial real estate (the OCC's handbook lists “mini-storage warehouse facilities” alongside hotels and nursing homes in that group), so a storage loan counts toward the bank's investment real estate exposure. A bank that is near its internal limit may pass on a good deal for reasons that have nothing to do with you.

Bank loans often have shorter terms than the amortization, which leaves a balloon at maturity. That is refinance risk, not just a date on a calendar.

SBA 7(a) and 504

The SBA's two main programs can finance real estate with less equity than a conventional loan, but they come with eligibility rules about passive real estate and occupancy that matter for storage in particular. The SBA lists the 7(a) maximum at $5 million; the 504 program pairs a bank first mortgage with an SBA-backed second through a Certified Development Company. The details, and the eligibility question, are in SBA loans for self storage.

CMBS (conduit) loans

A conduit lender originates the loan to sell it into a securitization. According to the OCC, loans from CMBS and life insurance companies usually have terms of 10 years or more at fixed rates and are commonly nonrecourse. The trade-off is rigidity. The CRE Finance Council describes CMBS call protection as some combination of lockout, penalty points, yield maintenance or defeasance, where defeasance means substituting government securities for the property as collateral so the loan stays outstanding. Nonrecourse is not absolute. The OCC notes that guarantees on nonrecourse loans usually include carve-outs for acts such as fraud, voluntary bankruptcy, environmental issues, unapproved liens and prohibited transfers, and some carve-outs make the loan full recourse. If the loan goes into default, a special servicer, not your loan officer, handles the workout. CMBS suits a stabilized facility you plan to hold through the term. It is a poor fit for a value-add plan you want to sell or refinance in three years.

Life insurance companies

Life companies lend from their own balance sheet for the long term, so they generally prefer lower leverage, strong sponsors and well-located, stabilized facilities. When a deal fits, they can offer long fixed-rate terms without recourse. When it does not fit, they usually decline rather than restructure.

Bridge lenders and debt funds

Bridge loans are for deals that do not yet qualify for permanent debt: a facility in lease-up, an expansion, a property with deferred maintenance, or a management turnaround. They are usually interest-only, floating-rate and short, and they are sized on a business plan rather than trailing NOI. The exit, a refinance or a sale, is the whole point, so a bridge lender will underwrite your takeout as carefully as your entry. More on this in the lease-up section below.

Seller financing

A seller note can replace a bank on a small deal or fill the gap between a bank loan and your equity. The senior lender has to agree to any second note, and you should expect it to test coverage on both loans combined. See seller financing for self storage for structures and a worked example.

How lenders size a self-storage loan

Nearly every lender runs the same three tests on the same NOI and lends the smallest answer. The only difference between lenders is the threshold each one sets and which NOI it accepts.

• DSCR is NOI divided by annual debt service. The OCC notes that the appropriate ratio depends on the amortization period and on how volatile the cash flow is. Storage has month-to-month tenants, so its income can move faster than a property with long leases.
• LTV is the loan divided by value. Under the federal banking agencies' real estate lending guidelines, value on a purchase loan means the lesser of the acquisition cost or the appraised value. If you negotiate a price below appraisal, the lender still lends on the price. If the appraisal comes in low, the lender lends on the appraisal. The same guidelines set a supervisory ceiling of 85% LTV for loans on improved property and 80% for commercial construction, and banks set their own internal limits below those.
• Debt yield is NOI divided by the loan amount. The OCC describes it as a risk measure independent of the interest rate, amortization and cap rate, which is why lenders use it to stop loans from growing too large when rates are low.

Typical ranges. For modeling a stabilized facility, many buyers start with a minimum DSCR around 1.20x to 1.35x, a maximum LTV between 60% and 75%, and a debt yield floor in the 8% to 10% area. These are modeling assumptions, not market data. Individual lenders sit outside these bands in both directions, thresholds tighten and loosen with the cycle, and the only current numbers are the ones a lender puts in writing for your deal.

The loan constant: why amortization changes loan size

The loan constant is annual debt service divided by the loan amount. It combines the rate and the amortization into one number, and it is what connects NOI to a loan amount under the DSCR test. A longer amortization lowers the constant, which raises the loan the DSCR test will allow, even though the rate is unchanged.

If the loan constant is higher than the cap rate you are paying, every dollar of debt costs more in payments than it earns in NOI. That is negative leverage: the loan still helps you buy the property, but it lowers your cash-on-cash return. See self-storage returns for how that flows into IRR.

Worked example: which test binds

Suppose you are buying a stabilized facility for $8,500,000 with a lender-underwritten NOI of $600,000, a 7.06% cap rate. The lender quotes 6.75%, a minimum DSCR of 1.25x, a maximum LTV of 70% and a minimum debt yield of 9%. All of these numbers are hypothetical.

On a 25-year amortization the 8.29% constant makes DSCR the tightest test: $600,000 ÷ (1.25 × 8.29%) is about $5.79 million, or 68.1% of the price, and your equity is about $2.71 million before closing costs. Stretch the amortization to 30 years and the DSCR test allows $6.17 million, so LTV takes over and caps the loan at $5.95 million.

Now change one term. If the lender's debt yield floor were 10.5% instead of 9%, the maximum loan would be $600,000 ÷ 10.5% = $5,714,286 under either amortization, and debt yield would bind. This is how debt yield works in practice: a better rate or longer amortization cannot push the loan past it.

Lease-up deals: why in-place NOI may not qualify

A facility that is two years old and 55% occupied is priced on what it will earn, but a permanent lender sizes on what it earns today. Suppose the same facility above has in-place NOI of $380,000 and a credible path to $600,000 in 24 months. On in-place NOI, the 25-year permanent loan tops out at about $3.67 million under the DSCR test, roughly $2.1 million less than it will support at stabilization. Most buyers cannot fill that gap with equity.

How a bridge loan with an interest reserve works

A bridge lender sizes on the business plan and makes the loan interest-only, with an interest reserve: an account the OCC describes as set up by the lender to cover interest during construction and lease-up. It is funded from loan proceeds or by the borrower at closing.

The shortfall on plan is $31,250, and it is $87,500 if a year goes by with no NOI growth. A careful lender sizes the reserve closer to the downside, and so should you. The OCC warns that interest reserves can mask a poorly performing project, which is why lenders watch reserve draws closely. If the reserve runs dry, you fund the interest out of pocket.

Test the takeout on day one

At $600,000 of stabilized NOI, the permanent loan from the worked example ($5.79 million) pays off the $5.5 million bridge. If lease-up stalls at $540,000 of NOI, the same terms support only about $5.21 million, and you need to find roughly $289,000 to refinance. Model the refinance at a higher rate than today's as well. The lease-up calculator helps you set a realistic ramp, and value-add self storage covers where the NOI growth has to come from.

What to compare on a term sheet

Two quotes at the same rate can be very different loans. Line them up on these points:

• Sizing: the minimum DSCR, maximum LTV and minimum debt yield, and which NOI they are applied to (trailing, in-place annualized or underwritten).
• Rate: fixed or floating, the index and spread, any floor, and when the rate locks.
• Amortization and interest-only: interest-only months raise early cash flow but leave a larger balance at maturity.
• Term and balloon: how the maturity lines up with your business plan and hold period.
• Prepayment: step-down, yield maintenance, defeasance or open, and the cost if you sell early.
• Recourse: full, partial, burn-off after stabilization, or nonrecourse with carve-outs.
• Covenants: ongoing DSCR tests and how the loan documents define income and expenses. The OCC notes that covenant DSCR can be calculated differently from underwriting DSCR.
• Reserves and fees: tax, insurance and replacement reserves, origination fees, exit fees and third-party costs.
• Secondary debt: whether a seller note or mezzanine loan is allowed at all, and on what terms.

Before you ask for quotes, run the deal through the deal analyzer so you know the loan amount the NOI actually supports. Walking in with a loan request that fails the lender's own tests costs you time on every call. Lender requirements and eligibility change, so confirm every assumption with the lender, and have your attorney review the loan documents before you sign.
