SBA 504 Self Storage Feasibility Study

Self storage approvals that never close

Self storage owners took 946 SBA 504 loans from FY2017 to FY2026, $1.22 billion of gross approvals, and what sets them apart is the share that never reached funding. Storage approvals dated FY2017 through FY2024 carry a 19.2% cancellation floor; count every storage approval still undisbursed as lost and it rises to 23.8%. The 7(a) self storage record cancels far less, and the 504 storage figure also clears our margin against the 504 program across all of its classes, so the high rate belongs to storage financed under 504 in particular. Funded facilities, by contrast, have not failed. On the 412 storage loans that funded between FY2017 and FY2021, SBA shows a charge-off floor of 0.00%, and the five-year figure is 0.00% as well. A 0.00% floor is not a promise: it says only that SBA had recorded no storage charge-off in that group by the data date.

Loan size, CDCs and the storage states

The median 504 storage loan is $890,000, a touch below the self storage median across both programs, and the middle half runs from $432,500 to $1.7 million. Franchising barely figures, at 0.74% of loans, so the lender is almost always underwriting an independent operator. WBD, Inc. is the current holder of 71 storage loans worth $51.7 million, and Mountain West Small Business Finance holds 66 worth $94.6 million. Florida Business Development Corporation follows with 49 loans and $89.2 million, then Granite State Economic Development Corporation with 44 and Michigan Certified Development Corporation with 43. The state table is unusually even at the top: Wisconsin with 74 loans, California with 71, Florida with 64, Utah with 63 and Texas with 60. Volume rose to 181 loans and $202.4 million in FY2021 and has since eased, to 59 loans and $107.9 million in FY2026.

What a 504 storage study should settle first

With a storage cancellation floor this high, the work done before approval carries real weight. A feasibility study has to measure existing and planned storage supply in the trade area and set it against the households and businesses that rent units, then test the lease-up pace a new facility can expect instead of assuming a stabilized first year. It has to price land, site work, buildings and climate control against bids, with a contingency the CDC and the bank will accept. Debt service coverage should be tested month by month through lease-up, not only at stabilization, because interest carried while units fill is where a storage budget usually strains. The appraiser will value the facility at stabilization and deduct for the lease-up still ahead, so the study's absorption schedule should match the one the appraisal uses. One limit on the data: RV and boat storage has no code of its own, so those yards are counted here alongside conventional self storage, or else under other warehousing.
