A semi-commercial mortgage is used for a property with both commercial and residential components.
A common example is a shop with a flat above it. Other examples may include an office with residential accommodation, a restaurant with rooms above, or a mixed-use building with business space and separate living space.
This type of mortgage requires careful consideration because the property is neither purely residential nor purely commercial.
The question is not only what the property looks like. It is how the property is used, how income is produced, and how the lender classifies the risk.
Quick Answer
A semi-commercial mortgage is a loan secured against a mixed-use property that contains both commercial and residential space.
It may be used to buy, refinance or raise funds against a property such as a shop with a flat above.
Lenders usually assess the commercial use, residential element, leases, rental income, property value, deposit, borrower experience and repayment plan.
What Counts as Semi-Commercial Property?
Semi-commercial property usually includes both business and residential use.
Examples may include:
- Shop with a flat above
- Office with residential accommodation
- Restaurant with living space
- Retail unit with flats
- Workshop with residential accommodation
- Mixed-use building with commercial and residential tenants
The lender will want to understand how the property is split. This may include floor area, title structure, access, leases, tenancy agreements and whether the residential part is separate from the commercial part.
Small details can matter. Separate entrances, lease length, planning use and rental evidence can all affect the lending route.
How Semi-Commercial Mortgages Are Assessed
Lenders may review:
- Commercial use
- Residential use
- Property value
- Rental income
- Lease terms
- Tenant strength
- Borrower experience
- Deposit or equity
- Loan-to-value
- Planning use
- Property condition
- EPC position
- Title structure
- Repayment plan
Some lenders may focus on rental income. Others may take a wider view of the borrower’s income and property strength.
The residential element can also affect whether the case needs closer regulatory review. This is why classification should be checked early.
Semi-Commercial Mortgage or Buy-to-Let Mortgage?
A buy-to-let mortgage is usually used for a residential property rented to tenants.
A semi-commercial mortgage is usually required when a significant portion of the property is used for commercial purposes.
A shop with a flat above it will not usually fit a standard residential buy-to-let route. It may need mixed-use or semi-commercial finance.
If the property is mainly residential, our Buy-to-Let Mortgages page may help you compare the wider route.

Why Lease Details Matter
Lease terms can affect the lender’s view of the case.
A lender may ask:
- Who occupies the commercial part?
- How long is the lease?
- What rent is being paid?
- Is there a break clause?
- Is the tenant trading well?
- Is the residential part let separately?
- Are there any vacant parts?
- Are the leases formal and up to date?
A strong lease can help support the application. A short lease, a weak tenant or a vacant unit may reduce lender confidence.
Deposit and Loan-to-Value
Deposit requirements vary.
Semi-commercial mortgages may require a larger deposit than standard residential mortgages because the lender is assessing more than one type of risk.
The loan-to-value may depend on:
- Property split
- Rental income
- Tenant quality
- Lease strength
- Borrower experience
- Property condition
- Commercial sector
- Residential tenancy position
- Overall lender appetite
If the property is unusual, vacant or reliant on one tenant, the lender may take a more cautious view.
Costs and Tax Points
Costs may include:
- Valuation fee
- Legal fees
- Arrangement fee
- Broker fee
- Early repayment charges
- Buildings insurance
- Survey costs
- Stamp Duty Land Tax
Mixed-use property can have different Stamp Duty Land Tax treatment from purely residential property. GOV.UK provides guidance on non-residential and mixed property SDLT rates.
Tax and ownership structure should be reviewed with a tax adviser.
EPC and Property Condition
For rented non-domestic property, energy efficiency rules can affect property planning.
GOV.UK provides guidance on the minimum energy efficiency standard for non-domestic private rented property.
A lender may also consider whether the property needs repairs, specialist reports or upgrades. This can affect valuation, costs and lender appetite.
Why Advice Matters
Semi-commercial mortgages sit between property categories.
That can make them useful, but it can also make them complex. A case may fail if it is sent to the wrong lender or described incorrectly.
An adviser can help review the property split, lease position, likely lender appetite, the evidence needed, and whether the case should be treated as semi-commercial, a commercial investment, owner-occupied, or another structure.
Good advice helps make the case clear before the lender asks the difficult questions.
