Semi-Commercial Mortgages
Support for mixed-use property purchases — including shops with flats above, offices with residential accommodation and other semi-commercial assets. NexGen Finance can help review semi-commercial mortgage enquiries across the UK.
What Is a Semi-Commercial Mortgage?
A semi-commercial mortgage — also known as a mixed-use mortgage — is a loan secured against property that combines commercial and residential elements within the same title. The most common example is a ground floor retail or office unit with one or more residential flats or maisonettes above, all held within a single freehold or leasehold title.
Because these properties sit between the purely residential and purely commercial categories, they require specialist lender consideration. Not all commercial mortgage lenders will assess mixed-use properties, and the underwriting approach differs from both standard residential and straightforward commercial transactions.
Types of Semi-Commercial Property
Shops with Flats Above
Ground floor retail unit with one or more residential flats on upper floors — one of the most common mixed-use arrangements.
Office & Residential
Office premises with residential accommodation — including professional practices operating from a building with an attached or above dwelling.
Pub or Restaurant with Flat
Hospitality premises with owner's accommodation or lettable residential space forming part of the same title.
Light Industrial with Residential
Workshop or light industrial unit with an attached residential dwelling — common in rural or semi-rural locations.
How Lenders Assess Semi-Commercial Property
Because mixed-use properties have two distinct income streams — commercial rent and residential rent — lenders assess both elements when determining affordability and loan-to-value.
Commercial Element Assessment
The commercial portion of the property is typically valued on a yield basis, reflecting the rental income and quality of the commercial tenant. Lenders will consider the length of the commercial lease, the tenant's covenant strength and any break clauses or upcoming rent reviews.
Residential Element Assessment
The residential flats or accommodation are valued using a comparable sales approach, similar to standard residential property valuation. If the residential parts are let, the rental income is factored into the overall assessment. If owner-occupied or vacant, the capital value is still used in the combined valuation.
Combined Valuation and LTV
A specialist commercial valuer will assess the whole property and produce a combined valuation. Deposits typically range from 25% to 40% of the combined valuation, though properties with vacant commercial units or weaker tenants may require more equity.
What Lenders Typically Consider
- ✓ Commercial rental income, tenant and lease terms
- ✓ Residential rental income or capital value of flats
- ✓ Overall combined valuation and loan-to-value
- ✓ Property type, location and condition
- ✓ Commercial to residential income split
- ✓ Borrower's financial profile and experience
- ✓ Whether the commercial part is let, owner-occupied or vacant
Valuation Challenges for Mixed-Use Property
Mixed-use valuations can be more complex than either residential or purely commercial property. The presence of a residential element above a commercial unit can sometimes complicate the valuation, particularly where the commercial unit is vacant, has a weak tenant or is operating in a declining retail location.
The proportion of commercial versus residential income also matters — a property deriving most of its income from residential lettings may be assessed differently from one where the commercial element dominates.
Financing the Parts Separately
In some circumstances it may be possible to finance the commercial and residential elements of a mixed-use building separately — using a residential mortgage for the flat and a commercial mortgage for the retail unit — where the property structure and ownership allows. This approach can sometimes access a wider range of lenders for each element but depends heavily on the legal structure and whether separate titles exist or can be created.

Frequently Asked Questions
What is a semi-commercial mortgage?
A semi-commercial mortgage is a loan secured against property combining commercial and residential elements — such as a shop with a flat above — held within the same title. It requires specialist lender assessment as it sits between residential and commercial categories.
How is a mixed-use property valued?
Mixed-use properties are valued by specialist commercial valuers who assess both the commercial and residential elements. The commercial portion is valued on a yield basis; the residential on a comparable sales basis. The combined figure determines the maximum loan.
What deposit do I need?
Deposits typically range from 25% to 40% of the combined valuation, depending on the property, lender and borrower profile. Vacant commercial units or weaker tenants may require a larger deposit.
Which lenders offer semi-commercial mortgages?
Not all commercial or residential lenders will consider mixed-use properties. Specialist commercial lenders and some challenger banks offer semi-commercial mortgage products. The available lenders depend on the specific property and circumstances.
Can the commercial and residential parts be financed separately?
In some cases, yes — where the legal structure allows. A residential mortgage could potentially be arranged for the flat element and a commercial mortgage for the retail unit. This depends on whether separate titles can be established and whether the overall arrangement is feasible given the ownership structure.
