Mixed-use property mortgages
Mixed-use properties combine commercial and residential space in a single building. They are common in the UK, particularly in town centres where shops or offices sit below flats. Financing these properties requires a specialist approach because they do not fit neatly into either residential or commercial mortgage categories.

What counts as a mixed-use property?
A mixed-use property is any building that has both commercial and residential elements. The most common example is a flat above a shop, but it can also include office buildings with a residential unit, pubs with living accommodation, or converted buildings with a mix of commercial and residential tenants.
How a lender classifies the property depends on the proportion of commercial to residential space. If the residential element is the majority, some lenders will treat it as a residential mortgage with commercial elements. If the commercial space dominates, it falls under commercial lending.
The classification matters because it affects the interest rate, deposit requirement, regulatory protections, and the lender panel available to you. Getting this right from the start saves time and avoids applications to the wrong type of lender.
How are mixed-use mortgages assessed?
Lenders assess both the commercial and residential elements separately and together. They will look at the rental income from each part, the overall condition of the building, the lease arrangements for commercial tenants, and the demand for both types of space in the local area.
Deposit requirements for mixed-use properties typically fall between residential and fully commercial levels, usually around 20–35%. The exact amount depends on the lender, the split between commercial and residential space, and the strength of the income.
Benefits of mixed-use property investment
Mixed-use properties can offer diversified income from different tenant types, reducing the risk of total void periods. If a commercial tenant leaves, the residential income continues, and vice versa. This diversity can make the overall investment more resilient.
They also offer the opportunity to live above your own business, combining a home and workspace in one purchase with a single mortgage. This can be more cost-effective than maintaining separate residential and commercial properties, though a dedicated buy-to-let mortgage may suit the residential element better in some cases.
Stamp duty on mixed-use properties is often calculated at commercial rates, which can be lower than residential rates for higher-value purchases. This is a significant advantage that many buyers are not aware of, and it can save thousands of pounds on the transaction.
