Semi-commercial property, also known as mixed use property is property with both residential and commercial elements.

These properties are often shops with flats above, offices with connected residential accommodation or sites with multiple properties on one title – part residential and part commercial.

Semi-commercial mortgages are a bespoke type of property finance designed to fund these exact properties.

They tend to be cheaper than full commercial mortgages, but more expensive than residential lending.

Applications can be full of nuance and for this reason, many borrowers choose to work with an experienced commercial mortgage broker.

Understanding Semi-Commercial Mortgage Rates

Semi-commercial mortgages are property-backed loans which are secured against property that is made up of both residential and commercial elements.

These mortgages are available for a wide range of properties, as long as they comprise of both residential and commercial portions, and can be used to purchase or remortgage a property.

These loans are generally funded using a commercial mortgage lender and are treated in much the same way as a commercial mortgage.

Factors Influencing Semi-Commercial Mortgage Rates

There are 6 key factors that influence semi-commercial mortgage rates. They are loan to value (LTV), property type, borrower experience, income & affordability, credit profile and lease structure (where let).

Loan to value represents a predictor of risk to lenders. For this reason, lower LTV applications tend to have lower rates. A higher LTV sees the opposite, and could see your choice of lenders reduce.

The property used as security for the loan is key. Standard retail units are seen differently to pubs, takeaways, or specialist businesses. The perceived resaleability and risk profile of the sector (for pubs in particular) impacts pricing.

The percentage split between residential and commercial can also make a difference to mortgage pricing.

Borrower experience is the next factor. If you’re a first time commercial property owner, you may find less lenders willing to lend and a small increase in cost.

Affordability, either profit and EBITDA for owner occupied applications or rental income for investment properties are key.

As with almost every type of lending, the credit history of the borrower has a big impact on eligibility and pricing. Where the borrower is a limited company, the credit history of both the company and it’s shareholders are taken into account.

The strength and stability of tenants and lease terms can also have a big impact on pricing.

Common Uses for Semi-Commercial Mortgages

Semi-commercial mortgages can be used for many purposes. These come down to one, or both of two approaches, for your business to occupy, or for investment purposes.

Semi-commercial property naturally comes with both residential and commercial elements, usually as two distinct units.

The commercial element can either be let or used for your own business purposes.

The residential element is usually let out on an AST, or a lease if let with the commercial part.

Should you wish to occupy the residential element, this may restrict your borrowing options, especially if the residential element is 40% or more of the total floor space.

Benefits of Financing a Semi-Commercial Property

The key benefits are:

  • Potentially stronger rental yields – Through the multiple income streams from both the residential and commercial units.
  • Diversification of rental income – Reduced reliance on a single tenant type
  • Flexibility of use – Owner-occupier and investment opportunities
  • Potential capital growth – Especially in mixed-use urban areas
  • Lower interest rates – Mixed use property often allows borrowing at lower rates than commercial mortgages for 100% commercial units.

Expert Tips for Navigating Commercial Mortgage Applications

When first taking on the commercial mortgage application process, there are a few quick tips that can make your life much easier. They are:

  • Consider using a broker – A broker can offer access to specialist lenders and could get you a better deal. They also save a lot of time as the semi-commercial mortgage application process is heavily criteria driven, so a good broker can help you to understand the nuance and find the right lender quickly, maximising your chances of approval.
  • Understand lender appetite early – Some lenders avoid certain property sectors entirely, so ensure your property type and commercial to residential split works for your chosen lender.
  • Focus on the full deal, not just rate – Fees, flexibility and exit costs matter more than you think for the overall cost of borrowing.
  • Prepare documentation upfront – The time spent doing this reduces delays and underwriting queries later on significantly.
  • Keep credit profile stable during application – Avoid unnecessary borrowing or missed payments during your application as they will heavily complicate matters.
  • Use realistic borrowing assumptions – Stress-testing affordability is essential, don’t look to overstretch yourself.
