Semi-commercial and mixed-use mortgages.
A shop with a flat above, an office with living space, a pub with rooms over. One building, two uses, and a lender panel of its own. For limited companies and SPVs.
What is a semi-commercial property?
A semi-commercial or mixed-use property is a single building with both a commercial and a residential part. The classic is a shop with a flat above it, but the category is wider than that: an office with living accommodation, a pub with rooms over, a takeaway with a maisonette, a former bank converted with apartments upstairs.
Semi-commercial and mixed-use are used to mean broadly the same thing. Some lenders draw a line between the two, using mixed-use for anything with more than one commercial unit, but for funding purposes you are in the same place: a building that is neither purely residential nor purely commercial.
That in-between status is the whole point. A standard residential lender will not touch it because of the commercial element. A purely commercial lender may not want the residential part. It sits on its own specialist panel, which is why it is treated as a specialism rather than a variation.
How lenders split the building.
The residential-to-commercial weighting is the single most important number in a mixed-use application, and most borrowers do not know it is being measured.
Lenders assess the mix, usually by floor area or by rental value, and sometimes by both. Where your building lands on that scale decides how the whole thing is underwritten:
Mostly residential
A small shop with several flats above may be underwritten close to a buy-to-let, on the rental income, with better loan to values.
Evenly split
The true semi-commercial middle: a specialist panel, priced between residential and commercial, and where broker knowledge matters most.
Mostly commercial
A large trading unit with one flat over is underwritten as commercial, on the business or the tenant, with commercial deposits.
Two lenders can measure the same building differently. One weighs floor area, another weighs rental income, and a shop with a high rent under two modest flats can be "mostly commercial" to the first and "mostly residential" to the second. Same building, two different answers, two different loan to values.
This is the most common reason a straightforward mixed-use purchase gets declined: it was presented to a lender whose measure of the split put the building outside their appetite. Presented to the right one, the same deal proceeds.
How much deposit do you need?
Commonly 25 to 35 per cent, so a loan to value of around 65 to 75 per cent.
Semi-commercial often prices a little better than pure commercial, because the residential element is seen as easier to resell if the lender ever has to. That is the upside of the mix. What moves it from there:
- The split. The more residential the building, the closer the terms move toward buy-to-let pricing and deposits.
- The commercial tenant. A national covenant on a long lease supports more borrowing than a local independent on a rolling tenancy.
- Whether it is let or vacant. An empty commercial unit produces no income, and the valuation will reflect it.
- The trade, if the commercial part is occupied by you. Owner-occupied semi-commercial is assessed on your business as well as the building.
- Separate access. Covered below, and it matters more than most people expect.
What catches people out.
Mixed-use has a short list of recurring problems, and all of them are cheaper to find now than at valuation.
- Shared access. A flat reached only through the shop, or up a staircase behind the counter, is materially harder to fund and to sell. Its own front door onto the street is worth real money. Some lenders simply decline where access is shared.
- Planning and use class. What the building is actually used for has to match what it is permitted to be used for. A flat created above a shop without consent is a problem that surfaces at legals, not before.
- The commercial tenant's trade. Some uses narrow the panel sharply. Hot food, licensed premises and anything with fumes, noise or late hours affect both the lender's appetite and the value of the flat above.
- One title or two. Whether the residential and commercial parts sit on a single title or separate ones changes the structure, and sometimes the exit: split titles can be sold separately later, which lenders and valuers both take into account.
- A vacant commercial unit. Harder, not impossible. Some lenders will proceed on the residential income and a discounted commercial value, but short-term finance is often the better route until the unit is let. Commercial bridging →
Why mixed-use needs a broker.
Mixed-use is the part of commercial lending where lender appetite differs most and is published least. There is no comparison table, because the answer depends on how a particular lender measures your particular building.
- We know who measures the split which way, so your building goes to a lender whose method puts it inside appetite rather than outside it.
- We present the tenancy and the trade properly, which on a semi-commercial building is often the difference between a yes and a query that kills the timeline.
- We flag access, use class and title problems before the valuer does, when they are still solvable.
- We cost the whole deal, not the headline rate.
We also buy, convert and regenerate commercial and mixed-use buildings ourselves, so we read these properties as an owner rather than only as a broker. Shops with flats over are a large part of the town-centre regeneration we do. See what we have built → · Meet the team →

Mixed-use mortgages, answered.
What is a semi-commercial property?
A single property with both commercial and residential parts, such as a shop with a flat above it, an office with living accommodation, or a pub with rooms over. Semi-commercial and mixed-use are used to mean broadly the same thing.
How much deposit do you need for a mixed-use mortgage?
Commonly 25 to 35 per cent, so a loan to value of around 65 to 75 per cent. Semi-commercial often prices a little better than pure commercial because the residential element is seen as easier to resell, but it varies with the split and the tenants.
How do lenders treat the residential part?
It depends on the weighting. Most lenders look at the split by floor area or by rental value. A mostly residential building may be underwritten close to a buy-to-let, while a mostly commercial one is underwritten as commercial. The split decides the lender, the loan to value and the rate.
Is a shop with a flat above a commercial mortgage?
Usually yes, as a semi-commercial mortgage. A standard residential lender will not lend on it because of the commercial element, and a purely commercial lender may not want the residential part, which is why it sits on its own specialist panel.
Can I get a mixed-use mortgage through a limited company?
Yes, and it is the only way we arrange them. Semi-commercial lending through a limited company or SPV is well served, and most specialist lenders in this space expect a corporate borrower.
Does separate access matter?
Yes, more than most borrowers expect. A flat with its own front door is materially easier to fund and to sell than one reached only through the shop, and some lenders decline where access is shared.
Can I get a mortgage on a mixed-use property with a vacant commercial unit?
It is harder, because the vacant part produces no income and the valuer will reflect that. Some lenders will still proceed on the residential income plus a discounted commercial value, and short-term finance is often the better route until the unit is let.
