LTV is influenced by: - Length of trading history and occupancy levels - Income diversification across customers - Type of facility (container, warehouse, purpose-built) - Location, access, and local demand - Strength of management and systems Stabilised, purpose-built sites with high occupancy attract stronger leverage than start-ups or container-only models. ### Affordability and Lending Assessment Affordability is assessed on a going-concern basis, with lenders focusing on: - Gross and net operating income - EBITDA and cash flow sustainability - Customer churn and pricing power - Cost structure, staffing, and marketing spend Debt Service Coverage Ratios (DSCR) are applied conservatively, with lenders often discounting early-stage or rapidly growing income. ### Valuation Methodology Self-storage valuations are typically income-led, reflecting the trading performance of the business rather than property value alone. Valuers consider: - Sustainable net operating income - Occupancy trends and pricing stability - Facility specification and security - Competitive environment and barriers to entry Underlying vacant possession value may be used as a secondary benchmark, particularly for warehouse-based facilities. ### Interest Rates and Loan Terms Self-storage mortgage pricing reflects both property and operational risk. Rates and terms depend on: - Loan-to-value ratio - Income stability and maturity of the business - Borrower experience and scale - Asset quality and location Loan terms typically range from 15 to 40 years, with repayment and interest-only options available for established operations. ### Commercial mortgage criteria Self-storage lenders will closely assess: - Degree of automation and management efficiency - Customer diversification and contract structure - Exposure to new competition - Planning status and permitted use Facilities with strong branding, technology-driven management, and stable occupancy are viewed most favourably. A self-storage business mortgage provides specialist commercial finance for an increasingly popular and resilient asset class. Well-established self-storage facilities with diversified income, strong occupancy, and experienced operators can secure long-term funding at competitive loan-to-value levels under commercial lending criteria. ## Talk it through with an adviser Speak to a Mortgage Lane adviser about your circumstances and the next steps.
