Semi-commercial mortgage calculator

Use our free semi-commercial mortgage (also known as mixed-use mortgage) calculator to find out how much the monthly payments could be, when taking out a semi-commercial property loan.

  • A semi-commercial mortgage is for a building that has a mixture of commercial and residential elements. For instance, a flat above a high street shop, which can be occupied either by the owner of the business or by a separate tenant.

If you are looking for rates for a buy to let mortgage, bought through a limited company, then please use our buy to let mortgage calculator.

The calculator on this page uses the semi-commercial mortgage rates currently available at your loan to value, to guide you on example monthly payments.

It is not a full commercial mortgage illustration or a guarantee of the rate you can secure.

Calculating the actual rate and monthly loan payment will depend on the rental income for an investment property, or the financial situation of an owner-occupied business.

Frequently asked questions

Semi-commercial properties, also known as mixed-use properties, are premises that serve as both residential and commercial spaces. Often, different parts of the building will be used either for business dealings or as living areas. 

Examples include a building with retail shops on the ground floor and flats on the upper floors. Semi-commercial mortgages cater to landlords that own these kinds of properties.

There are several lenders that specialise in commercial and semi-commercial mortgages. However, with mixed-use mortgage applicants, some of these lenders may be more discerning about how the property is used before they accept an application.

A lender may prefer it when a property is more residential than commercial. To give an example, a lender may only be willing to lend to semi-commercial landlords with properties that are at least 60% residential and 40% commercial. This is because the residential portion of the property may offer more stability and less risk in the eyes of a lender.

Yes, many lenders will accept rental income from the commercial portion of the property when assessing your eligibility for a loan.
