Semi-commercial mortgages in Grantham fund part-commercial, part-residential property: a shop with a flat above, an office with residential upper floors, a pub with accommodation, or a larger mixed-use block. We arrange them across Lincolnshire for investors, owner-occupiers and limited companies, structuring the loan around the split between the commercial and residential parts and placing it with the lenders that actually treat these assets well.

We assess a Grantham 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 steady, around 808 residential sales in the past year at a £220,000 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 Grantham property

We arrange the full range of semi-commercial and mixed-use finance for Grantham 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 Lincolnshire.

Mixed-use assets we finance across Grantham

Each kind of mixed-use asset is treated differently by different lenders, and we arrange finance for all of them in Grantham and across Lincolnshire. 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 Grantham market means for a semi-commercial valuation

Grantham is a value market within Lincolnshire, 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.

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. Grantham recorded around 808 residential sales over the past year at a median of £220,000, which makes the local market steady. New-build stock carries a premium of 24% 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.

How much can I borrow on a semi-commercial mortgage in Grantham?

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.

Which lenders offer semi-commercial mortgages in Grantham?

We hold more than one hundred lender relationships across high street banks, challenger banks and specialist lenders. The right lender for a Grantham 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 Lincolnshire.
