Semi-Commercial Mortgages | Gable Business Finance

Introduction

At Gable Business Finance, we help UK businesses and property investors access semi-commercial mortgages—a flexible financing solution for properties with both commercial and residential elements. Semi-commercial properties, sometimes called mixed-use properties, combine business operations with living spaces, offering opportunities for rental income, capital growth, or owner-occupied use.

Whether you are a landlord, investor, or business owner looking to occupy part of a property, a semi-commercial mortgage can provide tailored funding, flexible terms, and long-term financial benefits.

What is a Semi-Commercial Mortgage?

A semi-commercial mortgage is a loan secured against a mixed-use property, typically combining a commercial element (office, retail, or industrial) with a residential element (flat, apartment, or living space). The lender assesses the property’s total value, rental income potential, and the applicant’s financial capacity.

Key Features:

• Loan secured on a property with both residential and commercial elements.
• Flexible repayment terms, usually 5–25 years.
• Can be interest-only, fixed-rate, or variable-rate.
• Mortgage amount typically covers 60–75% of the property’s value.
• Rental income from residential or commercial units may be considered for affordability.

Semi-commercial mortgages are ideal for landlords, small business owners, or investors who want to combine property investment with operational space or rental income.

Benefits of Semi-Commercial Mortgages

1. Access to Mixed-Use Property Opportunities: Enables investors and business owners to purchase properties combining commercial and residential elements, creating multiple revenue streams.
2. Income Diversification: Rental income from residential units or commercial tenants can support mortgage repayments, reducing financial risk and improving cash flow.
3. Flexibility for Business Use: Businesses can occupy the commercial portion while generating income from residential or additional commercial units.
4. Long-Term Capital Growth: Mixed-use properties often appreciate over time, creating long-term asset value and potential for resale or refinancing.
5. Tax Advantages: Interest on the commercial portion of the mortgage is typically tax-deductible, and rental income can offset mortgage costs, improving overall financial efficiency.

3. Creditworthiness: Company and director or personal credit history.
