Semi-Commercial Mortgages

Edited: February 2026

Semi-commercial mortgages sit between Buy to Let and full commercial lending. They can be a strong option for experienced landlords and investors, but lender appetite depends heavily on the property itself, the tenant mix, and the borrower’s background.

Understanding how semi-commercial lending works is essential before proceeding, as these properties are assessed differently to standard residential or Buy to Let investments. At GPS Financial, we regularly advise on semi-commercial mortgages and help investors decide whether this type of finance is appropriate.

What Is a Semi-Commercial Property?

A semi-commercial property combines residential and commercial elements within the same building.

The most common example is a ground floor shop or commercial unit with one or more residential flats above. However, semi-commercial property can include any building where part is used for residential letting and part for commercial use.

Because of this mixed use, lenders assess both elements together rather than treating the property as purely residential or purely commercial.

Who Are Semi-Commercial Mortgages For?

Semi-commercial mortgages are generally aimed at experienced landlords and investors.

Lenders assess the borrower’s overall financial strength, property experience, and ability to manage mixed-use assets. A strong income can sometimes offset limited experience, but for most applicants, a track record of owning or managing investment property is important.

Borrowers with lower income and no property experience typically face more restricted lender choice.

Can You Buy Residential Property with a Commercial Mortgage?

The term “commercial mortgage” is often misunderstood.

In strict lending terms, commercial mortgages are used to purchase commercial property rather than residential property. While brokers often use the term commercial lending to describe non-residential finance more broadly, this does not mean a commercial mortgage is suitable for residential purchases.

Semi-commercial mortgages are a distinct category designed specifically for mixed-use properties that include both residential and commercial elements.

Are Semi-Commercial Mortgages More Expensive?

Yes.

Semi-commercial mortgages are typically more expensive than standard residential or Buy to Let mortgages. Interest rates are higher, and arrangement fees are often more substantial.

This reflects the increased complexity, specialist valuation approach, and perceived risk associated with mixed-use property.

What Is the Lending Criteria for a Semi-Commercial Mortgage?

Semi-commercial mortgages are often easier to obtain than full commercial mortgages because the residential element provides an additional layer of security.

Lenders usually assess:

• The proportion of residential versus commercial space
  • The type of commercial business operating from the property
  • The strength and length of the commercial lease
  • Rental income from both the residential and commercial elements
  • The borrower’s experience and overall financial position

Residential units are generally easier to let than commercial space, which makes properties with a strong residential element more attractive to lenders.

How Much Deposit Is Required?

Most semi-commercial mortgages require a deposit of around 25 percent, broadly in line with Buy to Let lending.

However, lender appetite is heavily influenced by the type of commercial business operating from the property. Some uses are less favoured, including certain leisure uses, charity shops, and tattoo studios.

Many lenders also apply limits to the residential and commercial split. For example, some will only lend where at least 60 percent of the floor space is residential, with no more than 40 percent commercial.

How Do You Apply for a Semi-Commercial Mortgage?

The application process is similar to other mortgage types, but underwriting is more detailed.

For the commercial element, lenders usually require:

• Details of the commercial tenant
  • The length of the lease, often a minimum of five years
  • Rental income and lease terms
  • Confirmation that the business use is acceptable

While applications can be made directly to lenders, many borrowers choose to work with a specialist broker to manage lender selection, valuations, and underwriting requirements.
