Underwriting a Birmingham semi-commercial commercial mortgage

Semi-commercial is the term for commercial mortgages on mixed-use property where the residential element is at least 40% of total floorspace, typically the classic shop-with-flat-above archetype that defines Birmingham suburban high streets. The product gives lenders comfort from the residential security (easier to re-let an empty flat than an empty retail unit), so semi-commercial routinely prices 50–100bps inside pure commercial investment on the same building.

There is one structural complication every borrower must understand. Commercial mortgages are unregulated by definition and fall outside the FCA's regulated mortgage perimeter, which is what we arrange. If the borrower or an immediate family member personally occupies the residential element, the deal moves inside the regulated mortgage perimeter and stops being a commercial mortgage. We do not hold FCA authorisation because the products we arrange are unregulated, so where a deal falls into regulated territory we refer it to a regulated mortgage broker partner. We flag this at outset rather than discover it three weeks into legals. The classic case: the independent retailer who buys the freehold of their shop and lives in the flat above sits inside the regulated perimeter; the same building bought as an investment with the flat let on an AST sits inside our unregulated commercial scope.

Active Birmingham semi-commercial spines: Moseley Village (Alcester Road) B13, Harborne High Street B17, Kings Heath High Street B14, Stirchley B30, and the Jewellery Quarter B18 conservation area. Most semi-commercial deals are £150K–£800K facility size. Worked example: a Moseley B13 shop with two flats above, £475K valuation, retail let on a 10-year FRI to a national coffee covenant, both flats let on ASTs (unregulated, in our scope). InterBay Commercial placed at 75% LTV, 6.95% pa on a 5-year fix, 25-year term, blended ICR 148%. Worked example two: a Kings Heath B14 shop-plus-three-flats with all flats let on ASTs to arms-length tenants, £585K, placed via Together at 70% LTV, 8.45% pa, blended ICR 145%.

The Birmingham semi-commercial estate

A deep, active product across Birmingham. The classic suburban high streets, Moseley Village B13 (Alcester Road), Harborne High Street B17, Kings Heath High Street B14, Stirchley B30 and the Jewellery Quarter B18 conservation area, all run on shop-plus-flat-above stock dating from the 1860s through the 1930s. Sutton Coldfield town-centre masterplan stock adds further suburban semi-commercial supply as it phases through. The semi-commercial market trades steadily, these assets rarely sit vacant for long because the residential element is intrinsically lettable.

Lender appetite for Birmingham semi-commercial

Strong on the unregulated cases we arrange. <strong>InterBay Commercial</strong> (OSB Group) is the most active named lender on the Birmingham shop-plus-flat archetype, typical 7.75–7.5% pa at 70–75% LTV. Together covers more challenged cases (vacant flat at acquisition, weaker commercial covenant) at 8.5–9.25% pa. <strong>Shawbrook</strong>, Aldermore, YBS Commercial, HTB and Cambridge & Counties all have meaningful semi-commercial appetite on let residential cases. Each has a distinct LTV / minimum-loan / covenant profile, we know which fits what. Cases that fall inside the regulated mortgage perimeter (owner-occupied residential element) are out of scope for us and we refer those to a regulated broker.

Semi-Commercial FAQs

Residential typically 40%+ by floorspace. Below that threshold, the deal is treated as pure commercial investment with wider pricing, sometimes 50–100bps wider. The split is measured by gross internal floor area; lenders' valuers calculate this from the RICS Red Book report, not from headline marketing particulars.
Currently 6.5–8.5% pa at 65–75% LTV on standard shop-plus-flat. Specialists like InterBay Commercial and Together quote competitively to 75% LTV. Strong-covenant retail with an established AST history on the residential element prices at the keener end; vacant residential or short-lease commercial pulls pricing wider.
Commercial mortgages are unregulated by definition and fall outside the FCA's regulated mortgage perimeter, and that is the territory we operate in. We do not hold FCA authorisation because the products we arrange are unregulated. Critical exception for semi-commercial: where the borrower or an immediate family member personally occupies one of the flats, the deal moves inside the regulated mortgage perimeter and is no longer in our scope. We refer those cases out to a regulated mortgage broker partner. Limited-company borrower with arms-length AST tenancies on the flat sits unregulated and is in our scope.
HMO blocks above commercial route through a slightly different lender pool, see our HMO block commercial mortgage page. Selly Oak student-let stock around University of Birmingham is the densest Birmingham HMO catchment. The product mechanics differ from standard semi-commercial, room-by-room ICR rather than blended building ICR, and a narrower lender pool.
No, buy-to-let products are sized against single residential dwellings let to AST tenants, not against commercial-plus-residential mixed assets. The semi-commercial route stays semi-commercial through any refinance. The exception is where the commercial element has been formally split off (separate title, separate access, separate utilities), at which point each element can be financed separately.
