Semi-Commercial Mortgages in Portsmouth
Mortgages and finance for shops with flats above, mixed-use blocks and other part-commercial, part-residential property in Portsmouth.
If you are buying or refinancing a mixed-use property in Portsmouth, the right loan is rarely the cheapest headline rate. It is the one whose lender understands how the residential element above a commercial unit affects value, income and risk. We arrange semi-commercial mortgages across Portsmouth and the wider Hampshire market, from a single shop with a flat above to a parade of units with residential uppers.
Lenders price a semi-commercial deal on the strength of the commercial covenant, the residential value and the combined rent. The local residential market is a direct input here, because the flats and maisonettes within a mixed-use asset are valued against it: Portsmouth is steady, with roughly 1,973 residential sales over the past twelve months at a £254,000 median, a useful read on the residential half of any semi-commercial property.
Funding a mixed-use purchase or refinance in Portsmouth
We arrange the full range of semi-commercial and mixed-use finance for Portsmouth property. A semi-commercial mortgage funds the purchase or refinance of an investment or owner-occupied mixed-use asset, typically to 70 to 75 percent of value, priced from around 6.5 to 8.5 percent a year. Where the residential element is large, a mixed-use mortgage may be sized on the blended income from both parts. Semi-commercial bridging covers a quick purchase, an auction lot or a property that needs works before it will support a term loan, usually from around 0.70 to 0.95 percent a month. For landlords holding several mixed-use or part-commercial assets, portfolio finance consolidates them under one facility. Once an asset is stabilised and let, a semi-commercial remortgage moves it onto a keener rate and releases equity for the next purchase in Hampshire.
The semi-commercial property we fund in Portsmouth
Each kind of mixed-use asset is treated differently by different lenders, and we arrange finance for all of them in Portsmouth and across Hampshire. That covers the classic shop with a flat above, offices with residential upper floors, pubs and guest houses with owner or letting accommodation, restaurants and takeaways with flats, retail parades with residential uppers, HMOs above commercial units, surgeries and professional premises with living space, and larger mixed-use blocks. The key question every lender asks is how much of the property, by floor area or value, is residential against commercial, because that split decides which desk will lend and on what terms. Local planning records show 109 residential units in the Portsmouth pipeline, a measure of the mixed-use and conversion activity that drives demand for this kind of finance in the area.

Mixed-use lending conditions in Portsmouth
Portsmouth is a value market within Hampshire, where keener prices can lift the yield on a mixed-use asset. Lenders will look closely at the strength of the commercial tenancy and the lettability of the residential space, so clear local evidence, of the kind set out below, helps secure competitive terms here.
Portsmouth occupies Portsea Island and the immediate mainland north of Portsbridge Creek, with the defence economy at HMNB Portsmouth and BAE Systems' surface ship business anchoring local employment alongside the University of Portsmouth and a hospitality base built around Gunwharf Quays and Southsea seafront. The Land Registry shows a median sale price of £255,000 across 1,979 transactions in the twelve months to March 2026, with year-on-year price growth of around 2%. The spread by property type is wide: detached houses median £510,000, semi-detached £335,000, terraces £260,000 and flats £165,000. Terraces and flats dominate volume because they dominate the housing stock. Harbour-front regeneration, notably around Tipner West and the wider city centre masterplan, continues to set the tone for larger schemes, but the day-to-day deal flow is built on Victorian and Edwardian terraces inside the island and small post-war infill around Cosham and Drayton.
The residential element: what local values tell a lender
Recent transactions confirm a market where the typical deal sits between £200,000 and £300,000. 33 Military Road in PO3 sold for £445,000 on 25 March 2026 as a terrace, while 51 Kirby Road in PO2 went through at £420,000 the same week as a semi. At the entry end, leasehold flats are still trading well below the median: Flat 81 Holmbush Court on Queens Crescent at £110,000 and Flat 10, 22 St Marys Road at £84,000 set the floor for cash and bridging buyers. Mid-market terraces such as 80 Mafeking Road at £205,000 and 50 Winter Road at £220,000 underline the values supporting most of the HMO change-of-use pipeline. The Land Registry recorded zero new-build sales over the 12-month window, which is consistent with a city where almost all output comes from conversion, refurbishment and infill rather than estate-scale new build.
This residential evidence values the living space within a mixed-use property and gauges how readily it would let or sell. It is not a guide to the commercial unit's value, which is tenant and covenant driven.

Semi-commercial mortgages in Portsmouth: common questions
How much can I borrow on a semi-commercial mortgage in Portsmouth?
Most lenders fund up to 70 to 75 percent of value on a semi-commercial mortgage, with the loan sized on the combined commercial and residential rent at an interest cover ratio. The Portsmouth residential market, currently steady, informs the value a lender will place on the residential element of a mixed-use asset.
Which lenders offer semi-commercial mortgages in Portsmouth?
We hold more than one hundred lender relationships across high street banks, challenger banks and specialist lenders. The right lender for a Portsmouth semi-commercial deal depends on the commercial-to-residential split, the leverage you need and whether you borrow personally or through a limited company, and we shortlist the desks most likely to fund it across Hampshire.
How does the Portsmouth residential market affect a mixed-use property?
It matters because the flats and living space within a semi-commercial asset are valued against local residential evidence. HM Land Registry records a £254,000 residential median in Portsmouth over the past year across roughly 1,973 sales, with flats around £165,000. The commercial element, by contrast, is valued on its tenant, lease and yield, which we assess case by case.
Do you arrange semi-commercial finance beyond Portsmouth?
Yes. We arrange semi-commercial and mixed-use mortgages across the whole of Hampshire and the wider UK, with the same approach: assess the commercial and residential split, model the combined income, and match the case to the lenders that treat that asset well.
