Frequently Asked Questions on Semi-Commercial Mortgages
What defines a semi-commercial or mixed-use property in the UK?
A semi-commercial property combines both commercial and residential elements within a single freehold or long-leasehold title. Common examples include ground-floor retail shops, offices, or veterinary clinics with self-contained residential apartments on the upper floors, or public houses with residential living accommodation.
What Stamp Duty rate applies to semi-commercial property purchases?
Mixed-use properties qualify for non-residential HMRC Stamp Duty Land Tax (SDLT) rates, capped at 5%, completely avoiding the 3% or 5% higher-rate residential surcharges levied on corporate buy-to-let purchases.
How do lenders stress-test rental income on semi-commercial property?
Lenders apply a composite underwriting test: the residential portion is typically stress-tested at a 125% ICR, while the commercial lease is tested at a 130% to 140% ICR hurdle, creating a weighted blended stress requirement across the combined passing rents.
Can semi-commercial mortgages be interest-only?
Yes. Most specialist semi-commercial lenders offer interest-only terms for UK Limited Companies and corporate SPVs, allowing property investors to maximise monthly surplus cashflow.
