Self-Storage Feasibility Study Consultants for SBA 7(a) and 504 Loans

SBA Feasibility Study LLC is an independent self-storage feasibility study consultant to SBA 7(a) lenders, 504 Certified Development Companies and their borrowers. Each study answers the questions a storage credit now turns on:

• How much competing supply will open before the facility stabilizes;
• What rents the trade area will pay while street rates are still falling;
• How long lease-up will take;
• How much reserve carries debt service until it does.

The answer is built from a named supply census that includes the pipeline, a household demand model, directly verified competitor occupancy and rates, and a monthly lease-up model tested against SOP 50 10 8.1. It is benchmarked against the firm’s own analysis of 2,896 SBA self-storage loans.

What a self-storage feasibility study consultant does for an SBA loan

A self-storage feasibility study consultant tests, independently of the borrower, whether a proposed, expanded or acquired storage facility can lease up, hold its rents and generate the net operating income required to service the proposed SBA debt. The study inventories every competing facility and every pipeline project by name; measures supply per capita today and at the subject’s stabilization date; builds demand from trade-area households; verifies competitor occupancy and rates directly; models lease-up month by month; and reports debt service coverage by year, with the reserve the ramp requires. It closes with a determination addressed to the lender.

SBA self-storage loan performance: the SBA Self-Storage Lending Ledger

SBA does not publish loan performance by industry. The firm computes it from SBA’s loan-level FOIA files and publishes the results, so a credit reviewer can test a storage file against the record of its class.

Disbursed loans only. Adverse resolution means purchased by SBA, liquidated or charged off. Seasoned means approved FY2010–FY2021, allowing at least four years of performance. The charge-off rate is by count on mature 7(a) cohorts. Full data methodology.

The seasoned cohort was approved before most of the 2021–2024 build wave, and facilities financed in that wave now appear disproportionately on CMBS watchlists (Exhibit 6). The class record is a reason a well-built storage file can be approved, not a substitute for supply and lease-up analysis. See the firm’s SBA Feasibility Risk Meter and property-type loss severity research.

SBA eligibility for self-storage loans

Self-storage is not on the special-purpose examples list in SOP 50 10 8, so conventional or climate-controlled facilities are treated as general-purpose collateral, subject to the lender’s verification of the governing SOP. The binding eligibility question is whether the borrower actively operates the business. 13 CFR 120.110(c) makes ineligible “Passive businesses owned by developers and landlords that do not actively use or occupy the assets acquired or improved with the loan proceeds (except Eligible Passive Companies under § 120.111).”

When an SBA lender orders a self-storage feasibility study

No SBA rule makes a feasibility study mandatory for a self-storage loan. 13 CFR 120.160(b) provides only that “SBA may require professional appraisals of the applicant’s and principals’ assets, a survey, or a feasibility study.” Lenders and CDCs commonly order one in four situations.

SOP 50 10 8.1 applies to loans receiving an SBA loan number on or after October 1, 2026 (Information Notice 5000-882227, September 25, 2026). Loans numbered on or before September 30, 2026 remain under SOP 50 10 8. See the October SBA regulatory update.

The study reconciles the seller’s management-software rent rolls, occupancy history and tax returns to the cash proof. It separates in-place rents from street rates and existing-customer rate increases, tests whether trailing performance reflects a facility still leasing up, and identifies the loan amount the historical earnings support. The acquisition loan default analysis provides the broader credit context.

How to choose a self-storage feasibility study consultant

A lender reads a self-storage feasibility study to decide whether it can rely on it. Seven tests separate a study that survives credit committee and SBA review from one that comes back with questions. They apply to any consultant, including this firm.

1. A named supply census that includes the pipeline. Every competing facility, project under construction and permitted project is listed. Supply per capita is shown today and at stabilization.
2. Demand built from households. Households, penetration calibrated to renter share, mobility and growth, average square feet rented, and business demand are modeled. Supply per capita alone is not demand.
3. Competitor occupancy and rates verified directly. Prospective-customer calls, online availability checks and site visits replace self-reported aggregator figures. The REIT-versus-independent gap is recognized.
4. Lease-up modeled monthly and stressed. The ramp is calibrated to recent competitors and stressed at plus 6 and plus 12 months, with reserve sized and DSCR by year.
5. Rates modeled honestly. Street rates, in-place rates, concessions and existing-customer rate increases are separated. Rate growth requires local evidence.
6. Current SBA rule fluency. General-purpose 504 equity tiers, the passive-business test including third-party management, and current acquisition and valuation rules are addressed.
7. Independence, a named signatory and willingness to say no. The study is addressed to the lender and signed by one accountable professional. The lease-up reconciles with the appraiser’s values. Evidence can support conditions or a not-feasible finding.

Who prepares your self-storage feasibility study

David Jones, MAI, CCIM, Principal, has completed more than 4,300 feasibility studies over his career across self-storage, hotels, RV parks, fuel and convenience, car washes, multifamily and healthcare. He is the author and signatory of every study the firm issues. SBA Feasibility Study LLC was founded in 2019 at 171 17th Street NW, Atlanta, GA 30363. Its studies have been accepted by 534 SBA 7(a) lenders and 107 Certified Development Companies across 50 states.

Every study is signed by the firm, with the analyst and reviewer identified. No white-labelling. No unsigned drafts that later become the basis for a credit decision. The firm is not a lender, broker, developer, REIT, management company or storage operator.

Determinations are the firm’s independent findings. Credit and eligibility decisions rest with the lender, the CDC and SBA.

What a self-storage feasibility study consultant analyzes

The Radius Study: Core Methodology

Self-storage feasibility revolves around a radius study that quantifies supply and demand within concentric distance rings around the subject site. This methodology is unique to self-storage and differs fundamentally from the trade area approaches used for hotels, gas stations, or restaurants.

The radius study produces a supply/demand snapshot at each ring. The critical output is the net rentable square feet per capita, which the firm benchmarks against national and regional averages to determine whether the market is undersupplied, balanced, or oversupplied. Where roads, rivers, or highways shape travel, the firm also tests drive-time trade areas, because a competitor two miles away across a barrier may not compete at all.

Square Footage Per Capita: The Key Benchmark

Square footage per capita (SF/capita) is the industry’s standard saturation metric. It divides the total rentable square footage of all storage facilities within a radius by the population within that same radius. The thresholds below are a widely used industry rule of thumb, not a published standard, so the firm uses them as a screen and confirm conclusions with a household demand model.

The national average is roughly 7.3 to 7.6 SF per capita depending on the data source (TractIQ: 7.28 as of September 30, 2026; StorageCafe: 7.6), and it masks enormous variation, from 2.0 square feet in Washington, DC and 2.4 in New York State (TractIQ) to far higher levels in smaller Sun Belt and Plains metros. Sun Belt markets with high population turnover (Phoenix, Dallas, Charlotte, Nashville) have higher per-capita demand than stable Midwest markets. College towns, military base communities, and markets with high renter populations also demonstrate above-average demand. The feasibility study must benchmark against regional norms, not the national average.

Household Demand Model

Per capita supply shows saturation; it does not measure demand. The firm builds demand directly: households in the trade area, multiplied by the share of households that rent storage, multiplied by the average square footage rented, plus business demand. Penetration is drawn from industry demand studies and calibrated to the trade area; StorageCafe reports that about a third of Americans currently use storage. Penetration is adjusted for the trade area’s renter share, mobility, household growth, and military or student populations using Census American Community Survey data. Supportable demand minus occupied existing supply and weighted pipeline supply equals the residual demand available to the subject.

Lease-Up Timeline Modeling

Self-storage has one of the longest lease-up periods in the SBA lending portfolio. Facilities that once stabilized in about 18 months now commonly take 24 to 36 months as new supply competes for the same tenants (Inside Self Storage, 2026 lender outlook), and in a 2025 lender survey, 88.2 percent of lenders named absorption risk as their top concern. This extended ramp period is the single most important factor in the DSCR projection and the most common source of feasibility study failures.

Illustrative lease-up path for a new facility in a balanced market; each study calibrates the curve to local absorption of recently opened competitors.

This lease-up period creates a cash flow gap that the feasibility study must explicitly address. The borrower needs sufficient capital reserves, or a lender-structured interest-only or reserve arrangement, to carry 18 to 36 months of sub-breakeven operations. SBA lenders will ask how the borrower plans to cover debt service during the ramp. The feasibility study must model the monthly cash flow trajectory through lease-up, not just the stabilized annual projection, and demonstrate when the DSCR crosses the lender's minimum threshold.

Sensitivity and stress testing. Every study includes a DSCR matrix that flexes stabilized occupancy, street rate versus in-place rate, concessions, lease-up duration (plus 6 and plus 12 months), and property taxes after reassessment, alone and combined. Lenders see both the month the DSCR crosses their threshold and how much cushion remains if the lease-up runs long.

The lease-up reserve

During lease-up, payroll, property taxes, insurance and debt service run at full weight while occupancy builds. The study models occupancy month by month, identifies the first month in which cash flow covers debt service and the first month run-rate coverage clears the lender’s standard, and sizes the reserve that carries the deficit until then. Lenders now cite 24 to 36 months to stabilization, against about 18 historically, and in one 2025 lender survey 88.2 percent named absorption risk as their top concern. In the illustrative case below, stretching lease-up from 18 to 36 months raises the reserve needed to carry debt service from about $455,000 to about $943,000.

Climate-Controlled vs. Drive-Up Unit Mix

Unit mix optimization is a critical feasibility study deliverable for self-storage. The mix of climate-controlled interior units versus conventional drive-up units directly affects construction cost, rental rates, operating expenses, and ultimately DSCR.

The optimal mix depends on the trade area demographics, competitive supply composition, and climate. Markets with high household incomes, significant business density, and hot/humid or very cold climates support a higher share of climate-controlled units (60% to 80%). Markets with lower incomes, more transient demand, and mild climates support a drive-up-heavy mix (60% to 70%). The feasibility study models both configurations and identifies which mix maximizes stabilized DSCR.

Competitor Occupancy Verification

Published occupancy data for self-storage competitors is unreliable. Facilities self-report occupancy to aggregators, and there is a systematic incentive to overstate. A competitor reporting 92% occupancy may be counting reserved-but-vacant units, including employee/owner units, or using a denominator that excludes non-rentable space.

The firm verifies competitor occupancy through direct methods: calling facilities as a prospective customer to inquire about availability by unit size, checking online reservation systems for real-time availability, and conducting physical site visits to observe drive-up unit activity (lock checks on a sample of units). These verification methods are more reliable than published data and, in the firm’s field experience, frequently show actual occupancy below what is reported. This discrepancy directly affects the demand calculation and the subject facility’s projected absorption rate.

REIT Comp Analysis

The self-storage sector is dominated by publicly traded REITs that provide transparent financial and operating data. Three public REITs now dominate: Public Storage, which closed its all-stock acquisition of National Storage Affiliates on July 22, 2026 and owned and/or operated 4,764 facilities at September 30, 2026; Extra Space Storage, which absorbed Life Storage in 2023 and owns or operates 4,410 stores including third-party managed locations; and CubeSmart, with 662 owned and 872 managed stores. Together they own, co-own or manage roughly 10,700 locations. Their quarterly earnings reports, investor presentations, and 10-K filings provide operating benchmarks that are more reliable than any industry survey.

The firm benchmarks the subject facility’s projected operating metrics against REIT performance data for the same MSA or region. For example, if REIT facilities in the subject’s MSA are achieving $18.50 per SF annually and the subject facility projects $22.00 per SF, the study must explain the premium with specific competitive advantages (newer facility, better location, underserved submarket). If the REIT achieves $18.50 and the subject projects $14.00, the study must explain the discount and demonstrate that the lower revenue still produces an adequate DSCR.

REIT data also provides same-store revenue growth trends, operating expense ratios, and cap rate benchmarks that inform the financial model's growth assumptions and exit valuation analysis. REIT data also shows how far institutional operations outperform the typical independent: Public Storage's same-store NOI margin was about 74% in Q2 2026, and same-store revenue ranged from minus 0.6% (Public Storage) to plus 2.4% (Extra Space) as rate competition continued; in Q3 2026 Public Storage’s same-store revenue turned positive at 0.5 percent. An independent's projected expense ratio and revenue growth must be benchmarked against that reality, not adopted from it.

New Supply Pipeline: The Critical Risk Factor

The single most common reason self-storage feasibility studies reach a negative conclusion is pipeline supply. A market that appears undersupplied at 6.0 SF per capita today may have 3 facilities under construction and 2 more in permitting that will push the ratio above 9.0 SF per capita within 18 months. By the time the subject facility completes construction and begins its own 18 to 36 month lease-up, the market may be significantly oversupplied.

The firm identifies pipeline supply through four sources: local planning department permit records (building permits and conditional use approvals), commercial real estate listing services, physical site visits to identify construction activity, and conversations with local planning staff about pending applications. The pipeline analysis is not optional. A feasibility study that quantifies existing supply without addressing planned additions is incomplete and will not withstand lender scrutiny. Nationally, the pipeline is shrinking: projects under construction equal about 2.1% of existing stock, and Marcus & Millichap counts 54.7 million square feet underway nationally. Local pipelines still vary widely, so the national trend never substitutes for a trade-area census.

Self-storage and boat and RV storage feasibility by format

• Climate-controlled multi-story. The dominant metro format, with the highest cost per square foot and the longest lease-up. Credit turns on visibility, household income, business demand and competing climate-controlled space. National climate-controlled street rates fell 2.1% annually in September 2026.
• Single-story drive-up. Lower cost and faster to build. Demand skews to contractors, vehicles and price-sensitive tenants in suburban and rural markets.
• Mixed-format facilities. Each unit type is modeled separately; alternative mixes are tested for stronger DSCR.
• Boat and RV storage. The boat and RV storage feasibility study draws demand from state vehicle and vessel registrations, waterways and recreation access rather than household density. Covered parking and canopy capital differ from enclosed storage. Where fuel is dispensed, fuel-station environmental rules apply. See also the RV park service page.
• Conversions. Retail and industrial conversions shorten construction, but ceiling heights, loading, fire separation and absorption must be tested.
• Acquisitions. Seller history is tested under SOP 50 10 8.1 (Exhibit 3). Third-party management is reviewed against the passive-business test.
• Cold storage. Cold storage more than half refrigerated is listed as special-purpose under SOP 50 10 8, subject to governing-version verification, with its own scope. See the Chicago cold-storage engagement.

Self-storage feasibility study vs market study vs appraisal

How Self-Storage Is Valued: Appraisal Methodology and Standards

The feasibility study and the appraisal answer different questions, but in an SBA file they have to agree. The study tests whether the facility can lease up and service its debt; the appraisal converts its income into value and sets the collateral position.

The standards behind the file

The appraisal follows USPAP (2024 edition, which has no fixed expiration date) and, for federally regulated lenders, the Interagency Appraisal and Evaluation Guidelines, which define market value and require as-is and, where relevant, prospective as-complete and as-stabilized values. SBA requires a USPAP appraisal by a state licensed or certified appraiser for 7(a) loans over $500,000 secured by commercial real estate, and construction loans are appraised at prospective value upon completion. Because self-storage is not a listed special purpose property, SBA’s separate land, building, equipment, and intangible allocation for going-concern special purpose appraisals does not normally apply. The Appraisal Institute's dedicated text is Self Storage Economics and Appraisal, 2nd edition, by R. Christian Sonne, MAI, with Jonathan Lang (June 2025).

Income approach

The primary approach. Stabilized net operating income is built from rental income at supportable street and in-place rates, less vacancy, concessions, and credit loss, plus ancillary income, less operating expenses including a market management fee, property taxes at post-sale or post-construction assessment, and replacement reserves. Direct capitalization values the stabilized facility; the average self-storage cap rate was about 6.59% in 2026 (Marcus & Millichap), listed facilities averaged a 6.92 percent asking cap rate across 59 listings in August 2026 (TractIQ), and prices sit about 20 percent below the 2022 peak (Marcus & Millichap), so an independent facility’s rate must reflect its own size, quality, and market. A discounted cash flow captures lease-up for new or non-stabilized facilities.

From stabilized value to as-is value

For a facility still in lease-up, the as-is value equals the stabilized value less the present value of the costs of getting there: rent lost during absorption, concessions, marketing, and an allowance for the entrepreneurial incentive a buyer would require to take on lease-up risk. This deduction is the bridge between the feasibility study's lease-up schedule and the appraiser’s as-is and as-stabilized values.

Sales comparison approach

Comparable sales are analyzed on price per net rentable square foot and price per unit, adjusted for occupancy, climate-controlled share, unit mix, age and construction (single-story versus multi-story), location and visibility, and the remaining lease-up. Sales of stabilized REIT-quality facilities and sales of lease-up properties are not interchangeable comparables without adjustment.

Cost approach

Land value plus replacement cost new, including indirect costs (the firm’s planning range is 10 to 20 percent of direct costs) and entrepreneurial incentive, less depreciation. It is a key test for new construction: if the stabilized value does not exceed total development cost with an adequate developer margin, the project is not financially feasible as proposed.

Real estate or business value?

Self-storage is generally valued as real estate. In St. Bernard Self-Storage, L.L.C. v. Hamilton County Board of Revision, 115 Ohio St.3d 365, 2007-Ohio-5249, the Supreme Court of Ohio upheld the rejection of a contractual allocation of about half the purchase price to goodwill because the owner “failed to prove the existence of any business value separable from the value of the real property”; later decisions, including Hilliard City Schools (2011-Ohio-2258), describe storage rental income as relating to rights appertaining to the land and improvements. Ancillary income such as truck rental or tenant protection programs may carry a business component, so the appraisal should state how it is treated.

Highest and best use

Every appraisal tests highest and best use as vacant and as improved: legally permissible, physically possible, financially feasible, and maximally productive. Storage is often the highest and best use of irregular, utility-burdened, or transitional sites, and its simple buildings retain conversion flexibility, one reason it is treated as general-purpose collateral. The feasibility study supplies the financially feasible test.

Environmental review

The lender’s environmental review follows SBA’s process for the subject’s NAICS code and site history. Where a boat or RV storage site dispenses fuel, SBA’s fuel-station rules apply. Environmental reports must be dated within one year of the SBA loan number. The governing SOP must be checked for each loan.

SBA eligibility and structure checklist for self-storage loans

The SOP reference, CDC compliance guide, site and regulatory methodology and financial projection methodology explain the supporting review. The study is an independent analysis, not an advocacy business plan.

Engaging the firm: process, fee and timeline

1. 1. Scope

   15-minute scoping call; every inquiry answered within one business day.

2. 2. Proposal

   Written proposal with firm fixed fee within one business day.

3. 3. Analysis

   Structured data request within one to two business days of engagement; midpoint findings review on substantial engagements; support through lender acceptance.

Self-storage feasibility studies cost $4,900 to $15,000, fixed before work begins. Single-format facilities with well-documented competitive data fall toward the lower end. Large mixed-format developments, conversions and secondary markets requiring extensive primary research push toward the upper end. The fee does not depend on the conclusion or whether the loan closes. See the cost and timeline guide.

Delivery is 10 to 15 business days from a complete data response. Competitor verification through calls, online availability checks and site visits is the timeline constraint and is not compressed.

Data request checklist

• Site address, parcel and acreage.
• Site plan with net rentable square feet by climate-controlled, drive-up, boat and RV unit type; building count and stories.
• Development budget or purchase contract.
• Proposed loan structure, SBA program and lender or CDC.
• For existing facilities: three years of P&L and tax returns; rent roll, occupancy by unit type, move-ins and move-outs, street and in-place rates, concessions and existing-customer rate increases; any management agreement.
• Zoning and entitlement status; existing appraisal or environmental reports.
• Sponsor’s storage operating experience and operating plan.
