We arrange semi-commercial and mixed-use mortgages in Marlborough for purchases, remortgages and portfolios from around 150,000 pounds upward. Whether the asset is a retail unit with a flat above, a guest house, a surgery with residential accommodation or a mixed-use investment block, we assess the commercial and residential split, model the combined income, and take the case to the lenders most likely to fund it in Wiltshire.

We assess a Marlborough semi-commercial case on its combined commercial and residential fundamentals, with the local residential market as a gauge of the value and lettability of the living space. That market is limited, around 225 residential sales in the past year at a £440,000 median, which helps test the residential element of a shop with a flat above or a mixed-use block.

How we structure semi-commercial finance for Marlborough property

We arrange the full range of semi-commercial and mixed-use finance for Marlborough 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 Wiltshire.

Mixed-use assets we finance across Marlborough

Each kind of mixed-use asset is treated differently by different lenders, and we arrange finance for all of them in Marlborough and across Wiltshire. 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.

What the Marlborough market means for a semi-commercial valuation

Marlborough is a mid-market location within Wiltshire, where semi-commercial values rest on a sound commercial tenant and a residential element that lets readily. That profile suits a mainstream semi-commercial mortgage at 70 to 75 percent of value, and it is among the more straightforward backdrops for a lender to underwrite.

The residential element: what local values tell a lender

The flats and living space within a semi-commercial asset are valued against local residential evidence, so sold-price depth is a direct input on a mixed-use deal. Marlborough recorded around 225 residential sales over the past year at a median of £440,000, which makes the local market limited. New-build stock carries a premium of n/a over existing stock here. The commercial element of the property, by contrast, is valued on its tenant, lease and yield, which we assess case by case.

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.
