Semi-commercial mortgages for mixed-use property

Semi-commercial mortgages are designed for mixed-use properties that combine residential and commercial elements in one asset. Common examples include a shop with a flat above, a mixed-use investment building, or a property with both trading and residential income components.

What Is a Semi-Commercial Mortgage?

A semi-commercial mortgage is used for a property that includes both residential and commercial space. Because the building sits between two lending categories, it often requires a more specialist mortgage approach.

These properties do not always fit standard residential or standard commercial criteria cleanly, which is why specialist structuring matters.

What Types of Mixed-Use Property Can Be Funded?

Typical examples include a shop with flat above, mixed-use investment property, or buildings where residential and commercial income sit side by side.

The balance between the two uses can affect how lenders view the case.

How Semi-Commercial Finance Works

Lenders will usually assess the property layout, valuation, use split, income profile, and marketability. They may also look at how the property would perform if either the residential or commercial part changed.

That mixed profile is what makes semi-commercial lending more specialist. Borrowers looking for a broader understanding of commercial property borrowing can explore Commercial Property Finance to see how different asset types are funded.

What Lenders Assess on Mixed-Use Assets

Lenders often look at the relationship between residential and commercial value, rental income, lease structure, and how easy the building would be to sell or refinance later.

A cleaner, more understandable mixed-use asset usually presents better than a confusing one. Where rental income and investment performance are key considerations, Commercial Investment Mortgages explain how lenders assess income-producing commercial assets.

Why Specialist Structuring Matters

Semi-commercial property sits right on the line between residential and commercial lending. That means lender appetite varies more than many borrowers expect.

The right lender can make the case feel straightforward. The wrong lender can slow the whole process down.

Who semi-commercial mortgages suit

They suit investors buying or refinancing a mixed-use building let to both commercial and residential tenants, and business owners who trade from the commercial part while the space above is let. Landlords adding a mixed-use asset to a wider portfolio use them too, as do owners releasing equity from a building they already hold. Lenders take account of your experience with let property, but the building and its income usually sit at the centre of the case.

What to have ready

A clear picture of the building helps lenders assess it quickly. Useful information includes:

• Floor plans or a description showing how the space is split between uses
• Leases for the commercial unit and tenancy agreements for the residential parts
• A schedule of current rents and any vacant space
• Planning history, particularly if the use of any part has changed
• Business accounts if you trade from the commercial unit
• Proof of identity, address and recent bank statements

Costs to plan for

Expect an arrangement fee, often 1% to 2% of the loan, a valuation fee that reflects the property's size and type, and legal costs for both your solicitor and the lender's. A broker fee may apply and should be agreed before you instruct. If fees are added to the loan or deducted from it, check both the total you will owe and the net amount you will receive.

Steps in a semi-commercial application

We start with the layout, the income and your plans, then approach lenders whose appetite matches the mix of uses. Lenders and valuers look at the relationship between the residential and commercial value as well as the building as a whole, so accurate rent and lease information matters. Instructing solicitors early helps, as there may be both commercial leases and residential tenancies to review.

Risks and repaying the loan

Because lender appetite for mixed-use buildings varies, it is worth thinking early about how easily the property could be refinanced or sold later. A vacant shop or short leases can affect both value and lender interest. If the loan is interest-only, decide early how the balance will be repaid at the end of the term, whether by refinance, sale or another agreed route.

When a semi-commercial mortgage is regulated

Whether a mortgage on a mixed-use building is regulated depends on who borrows, how much of the building is a dwelling and who lives there. The FCA's guidance on regulated mortgage contracts sets out the tests, which have applied in their current form since 21 March 2016:

• Business-only property and company borrowers. A loan secured on property used wholly for business cannot be a regulated mortgage contract. Nor is a loan to a company to fund its business, secured on the company's property.
• The 40% test. A loan to an individual (or to trustees) falls within the definition when at least 40% of the property is used, or intended to be used, as a dwelling, and it is then regulated unless an exclusion applies. Floor area is what is measured, adding together every storey. The borrower does not have to be the person who lives there.
• The main exclusion. The loan is excluded where the individual borrows wholly or mainly for business purposes and less than 40% of the property is lived in by them or a related person: a spouse or partner, parent, brother, sister, child, grandparent or grandchild. A shop with flats let to unconnected tenants as an investment usually falls here.
• Living above the shop. If you borrow in your own name and you or a close relative live, or will live, in a flat that is 40% or more of the building, expect a regulated case.

Status turns on the facts when each loan is taken out, so anything unclear has to be checked case by case. Arranging or advising on a regulated mortgage contract is itself a regulated activity, so a regulated case must be handled by a firm with the right FCA permissions. You can check any firm on the FCA Register. Rules change, so check the FCA's guidance for the current wording.

Refinancing a mixed-use property

A mixed-use building can be refinanced like other commercial property, to replace a loan that is ending or to release equity. The new lender revalues the building and looks again at the commercial lease and the residential tenancies, and because a remortgage is a new loan, the test above is applied afresh.
