Yes, mortgages for mixed residential and commercial properties are often available in the UK, but they are assessed very differently from standard residential mortgages. Not all lenders will consider them, however many mainstream and specialist lenders may lend where the property, income profile, and structure are suitable.
A mixed-use property typically combines residential accommodation with commercial premises, for example a flat above a shop, a house with a ground-floor office, or a building with both retail and living space.
Lenders usually focus on the commercial element’s risk, the percentage split between residential and commercial space, and how easily the property could be resold.
These mortgages are commonly assessed under commercial or semi-commercial criteria, even when the residential portion is substantial.
Loan to value limits are often lower than standard residential mortgages, interest rates may be higher, and underwriting is more manual. Lease terms, tenant type, planning use class, and property access all matter.
Borrowers who benefit most include owner-occupiers, landlords, and business owners purchasing premises with living accommodation.
Missing one lease clause or misunderstanding planning use can derail an application late in the process. This is why many borrowers use an experienced mortgage broker to navigate lender appetite and policy exceptions.

Final Thoughts and Next Steps
1. What Is a Mixed Residential and Commercial Property?
A mixed residential and commercial property contains both living accommodation and income-generating commercial space within the same title.
Common examples include:
A flat above a retail shop
A house with an attached office or surgery
A pub with owner accommodation
A building with ground-floor commercial and upper-floor flats
The key point is that the property cannot be classified as purely residential. Even a small commercial element often changes how lenders assess risk.
2. Why Do Lenders Treat Mixed-Use Properties Differently?
Lenders view mixed-use properties as higher risk for several reasons:
Resale complexity, fewer buyers if repossessed
Commercial income volatility, especially retail or hospitality
Specialist valuation, requiring commercial surveyors
Planning and lease risks, especially short or restrictive leases
According to UK Finance data, semi-commercial properties historically experience higher arrears volatility than owner-occupied residential lending, which drives stricter criteria.
3. The Lender Acceptance Spectrum Explained
Rather than a simple yes or no, lenders sit on an acceptance spectrum:
Near-residential: Small commercial unit, strong residential dominance
Balanced mixed-use: Roughly equal residential and commercial split
Commercial-heavy: Majority income from business premises
The closer a property sits to residential use, the broader the lender pool often becomes. Once commercial income dominates, assessment shifts towards commercial lending standards.
4. How Much Can You Borrow on a Mixed-Use Mortgage?
Borrowing is typically assessed using a blend of:
Property value
Commercial rental income
Personal income and affordability
Business accounts if owner-occupied
Some lenders use interest coverage ratios for the commercial element, commonly stress-tested above pay rate. Others apply affordability models closer to buy-to-let rules.
5. Deposit and Loan to Value Expectations
Deposits are usually higher than standard residential mortgages.
Typical ranges seen in the market:
25 to 40 percent deposit for many mixed-use properties
Lower LTVs if retail or hospitality is involved
Higher LTVs sometimes considered where residential space dominates
Missing one planning detail can push a case into a lower LTV band, which can materially change affordability.
6. Interest Rates and Product Types
Interest rates are often higher than standard residential products due to:
Specialist underwriting
Manual assessments
Commercial risk weighting
Products may be fixed, variable, or semi-commercial trackers. Terms are often shorter initially, with reassessment at review.
7. Buy-to-Let and Investor Considerations
For investors, lenders usually focus on:
Quality and length of commercial lease
Tenant type and trading history
Rental sustainability
Retail units with national tenants often perform better than niche or seasonal businesses. Short leases can limit lender appetite even if income is strong.
8. Owner-Occupiers and Business Owners
Business owners purchasing premises with living accommodation are assessed differently.
Underwriters often ask:
Is the business sustainable?
Does the property rely on one operator?
Can the residential space be sold separately?
Strong trading history can help offset weaker property features.
9. What Surveyors and Underwriters Actually Look For
Surveyors focus on:
Marketability in forced sale
Comparable mixed-use transactions
Condition and compliance
Underwriters focus on:
Lease clauses and break options
Planning use class alignment
Income durability
A single restrictive clause can trigger further queries late in the process.
10. Common Red Flags That Cause Declines
Short commercial leases with no renewal rights
Access to residential accommodation only through commercial space
Non-standard construction
Planning inconsistencies
These do not always mean decline, but they narrow options quickly.
11. Policy Exceptions, When Lenders Bend the Rules
Some lenders will consider out-of-policy cases where compensating factors exist, such as:
Lower loan to value
Strong personal income
Long-standing tenants
Proven resale demand
This is where broker experience often matters most.
12. Step-by-Step Mortgage Journey
Mixed-use cases benefit from upfront structuring.
13. How This Compares to Standard Residential Mortgages
Key differences include:
Higher deposits
Slower underwriting
Specialist valuation
Greater document requirements
This is not a disadvantage, just a different lending framework.
14. Timescales and Why Mixed-Use Takes Longer
Expect longer timelines due to:
Commercial valuation availability
Underwriter queries
Legal review of leases
RICS data shows commercial valuations can add several weeks compared to residential surveys.
15. Hidden Costs People Often Forget
Commercial valuation fees
Legal costs for lease review
Business accounts preparation
Stamp duty complexity
Budgeting early avoids surprises.
16. Market Trends, What’s Changed in the Last 12 Months
In the past year:
Greater scrutiny of retail units
Increased focus on lease length
Stronger appetite where residential dominates
ONS data shows mixed-use transactions remain stable despite broader market shifts.
17. Broker Insights, What We See Most Often
Common issues include:
Applicants assuming residential rules apply
Underestimating lease importance
Applying too late for specialist advice
Over 120 clients in the last year secured complex property mortgages through structured broker support.
18. Pros and Cons of Mixed-Use Mortgages
Pros
Potentially higher yields
Diversified income streams
Often lower purchase prices
Cons
Higher deposits
More complex underwriting
Limited lender pool
19. Myth vs Reality
Myth: Mixed-use properties are unmortgageable
Reality: Many are financeable with the right structure
Myth: Residential space guarantees approval
Reality: Commercial risk often dominates decisions
20. Case Study
A client purchasing a flat above a takeaway faced decline due to lease length. By restructuring the lease and reducing loan to value, a specialist lender approved the mortgage within revised policy.
