Getting a mortgage on a storage unit

We assist borrowers with commercial mortgages for storage unit and self-storage facilities, supporting acquisitions, refinances, and expansion of storage operations. Storage unit mortgages are a specialist area of commercial lending and are typically available at up to 75% loan-to-value (LTV), subject to operator experience, income stability, and asset quality.

This level of leverage allows investors and business owners to scale efficiently while retaining capital for operational growth and site optimisation.

Experience and Lender Appetite

Operator experience plays a material role in determining mortgage terms for storage facilities.

Experienced operators (typically 2-3+ years in self-storage or similar asset classes) generally access the most competitive rates, higher leverage, and wider lender choice.

New entrants can still obtain funding, but underwriting is usually more conservative, with tighter stress testing, higher pricing, or additional conditions.

Where experience is limited, lenders will look for other risk mitigants, such as strong financial backing, professional management, or a clearly evidenced demand profile.

Key Underwriting Considerations

When assessing storage unit mortgages, lenders focus on:

• Occupancy levels and churn
• Rental structure and pricing
• Formal lease or licence agreements for each unit
• Operating costs and net income sustainabilityLocation, access, and local competition

Ensuring that units are formally leased or licensed is critical, as lenders rely on documented rental income to assess affordability and valuation.

Valuation and Income Assessment

Storage unit facilities are typically valued on an income-led basis, with lenders assessing sustainable net income rather than headline turnover. Well-documented rental evidence, consistent occupancy, and scalable pricing structures materially improve valuation outcomes and borrowing capacity.
