Semi-Commercial Property Finance
Finance for mixed-use property, a shop, office or unit with residential space above or attached, structured around how lenders actually split and assess the two elements, not treated as a standard commercial mortgage with a flat bolted on.
Not quite commercial, not quite residential
Semi-commercial property sits in its own category, and it’s often assessed poorly as a result, either forced into a standard commercial mortgage that ignores the residential income, or into a buy-to-let product that ignores the commercial risk. Neither gives an accurate picture of the deal.
A wholly commercial unit, or a residential buy-to-let with no trading element. Standard commercial and BTL products are priced and underwritten for a single, uniform income stream.
One security, two income streams: a commercial lease and a residential tenancy, each assessed separately, then combined into a single facility structured around both.
Why this is worth looking at now
Mixed-use lending has been growing at a meaningfully faster rate than the wider specialist property finance market, driven by more challenger and specialist lenders entering the space and building out dedicated mixed-use products. It also remains one of the least consistently tracked corners of UK property finance, which in practice means less standardisation and more variation in appetite between lenders on an identical deal, exactly the condition where independent, whole-of-market structuring earns its fee.
A lender looking at a semi-commercial deal is really underwriting two separate questions at once: is the commercial tenant’s covenant strong enough to support that portion of the loan, and does the residential rent independently stand up to a standard assured shorthold stress test. A deal that looks strong on blended income can still fail if either element is weak on its own. Structuring the application around both, rather than one combined figure, is what determines which lenders will actually engage.
How lenders assess the split
| Factor | What lenders look at |
|---|---|
| Loan to value | Typically 65 to 75%, moving lower as the commercial proportion of the property increases |
| Commercial element | Tenant covenant strength, lease length remaining, sector of the trading business |
| Residential element | Assessed independently on an assured shorthold tenancy basis, separate from the commercial lease |
| Vacant commercial space | Narrows the lender pool considerably, usually requires a letting strategy or a bridge to stabilisation first |
| Valuation | Often requires two figures within one report, a commercial valuation and a residential valuation, not a single blended number |
How we arrange it
Split the deal before we approach anyone
We assess the commercial and residential elements separately, tenant covenant, lease terms, rental cover on the flat, before building the case, so we’re not presenting a blended figure a lender will pick apart.
Match lender appetite to the actual split
Appetite for semi-commercial varies sharply between lenders depending on the ratio of commercial to residential value. We approach the ones whose criteria genuinely fit this specific split, not a generic commercial panel.
Stress-test before you commit, not after
Where useful, we model the deal against void periods, tenant default and valuation movement before you proceed, the same Monte Carlo approach we use on development appraisals, applied here to the specific risks of a mixed-use security.
Frequently asked questions
What counts as a semi-commercial property?
A property with both a commercial and a residential element under one title, most commonly a shop, office or takeaway with a flat above, or a small parade with residential units built in. Lenders often refer to this as mixed-use property.
Is semi-commercial finance the same as a commercial mortgage?
No. A standard commercial mortgage is priced and assessed against a wholly commercial property. Semi-commercial finance is assessed against two separate elements within one security, each valued and stress-tested differently by the lender.
How much can I borrow against a semi-commercial property?
Typically up to 65 to 75% loan to value, though the figure a lender will actually offer depends heavily on the proportion of the property that is commercial versus residential, and on the strength of the commercial tenant if one is in place.
Does the residential element need to be let separately?
Usually yes. Most lenders require the residential unit to be let on an assured shorthold tenancy, separate from the commercial lease, and will assess rental cover on that unit independently of the commercial income.
Can I get semi-commercial finance with no commercial tenant in place?
It is possible but the lender pool narrows considerably. Vacant commercial space is treated as a risk to income, and most lenders will want a credible letting strategy or a shorter-term bridge to stabilisation before considering a term facility.
Why use a broker for semi-commercial finance rather than approach a lender directly?
Semi-commercial is a smaller, less standardised part of the lending market than residential or pure commercial property, and appetite varies significantly between lenders on the same deal. A broker who structures these regularly knows which lenders will actually look at your specific split of commercial and residential income, rather than starting from a generic panel.
