TL;DR- Mixed use properties combine two or more planning uses - residential, commercial, industrial, leisure - on a single freehold or leasehold title.
- Lenders assess each element separately and use a combined income and valuation approach.
- Standard residential and standard commercial mortgage products are typically not suitable - specialist mixed use or semi-commercial lenders are required.
- The complexity of mixed use properties means specialist valuation, legal advice and mortgage brokerage are important.
What Counts as Mixed Use?
Mixed use, in a property and mortgage context, refers to properties where two or more distinct use classes are present on a single title. Under the Town and Country Planning (Use Classes) Order 1987 (as amended), different property uses are classified into use classes - residential (C3), offices (E(g)(i)), retail (E(a)), industrial (B2) and so on. A property that combines uses from different classes on a single title is a mixed use property.
Common examples include: retail with residential above; office building with ground floor cafe or restaurant; workshop or studio complex with a caretaker dwelling; and leisure facilities with residential accommodation. The specific combination of uses determines the mortgage product required and the lender universe available.
Income Assessment for Mixed Use
Each income-generating element of a mixed use property is assessed separately. For let elements, the rental income from each tenant is assessed against the market rental value for that use. For owner-occupied elements, the trading income or owner-occupation value is assessed. The lender combines the income streams to calculate the overall debt service coverage for the loan.
Vacancy risk is a significant consideration in mixed use assessment. If one element becomes vacant, the income reduction must be sustainable within the borrower's overall financial position. Lenders typically apply stressed vacancy assumptions to each element in their assessment.
Valuation of Mixed Use Properties
Mixed use properties are valued using a combination of methods appropriate to each element: investment yield for let commercial elements; comparable or investment method for residential elements; and profits method for specialist trading elements. A RICS-qualified valuer with mixed use experience is required. The valuation complexity means that valuations for mixed use properties take longer and cost more than standard residential valuations.
Finding a Lender for Mixed Use
Mainstream residential and standard commercial lenders typically cannot accommodate genuinely mixed use properties. Specialist lenders - challenger banks, specialist commercial lenders and some building societies - operate in this space. The lender universe is smaller than for standard residential or commercial properties, and rates and minimum deposit requirements are typically higher. A specialist commercial mortgage broker is essential for identifying current lender availability and for presenting the application in a way that works for the specific property mix.
Frequently Asked Questions
Is a mixed use mortgage regulated by the FCA?
The regulatory status depends on the predominant use. If the residential element represents more than 40% of the total floor area and the borrower or a family member will occupy it, the loan may be regulated under the Mortgage Credit Directive. If the commercial elements predominate, the loan is typically unregulated commercial finance. The regulatory position should be confirmed with the lender and broker for any specific property.
Can I convert a mixed use property to fully residential?
Converting a commercial element to residential use may be possible under permitted development rights (subject to prior approval) or through a full planning application. Once fully residential, a standard residential or buy-to-let mortgage may be available. The costs and risks of the conversion - planning, building works, void period during works - should be assessed before committing to this strategy.
How does stamp duty apply to mixed use properties?
Stamp duty land tax on mixed use properties is charged at commercial SDLT rates (which are generally lower than residential rates and do not attract the additional property surcharge) where the property genuinely has a commercial element. HMRC has specific guidance on the SDLT treatment of mixed use properties - whether commercial rates apply depends on the nature and proportion of the commercial use. Specialist legal and tax advice should be sought for any mixed use SDLT question.
Are mixed use properties harder to sell?
Mixed use properties have a more limited buyer market than standard residential or commercial properties, as they require a buyer who understands and wants the specific combination of uses. This can make them harder to sell quickly and may result in longer marketing periods. This reduced liquidity is a factor lenders consider when assessing mixed use mortgage applications and is reflected in lower LTV ratios.
