Semi Commercial Mortgage Dorset

The situation

An experienced portfolio landlord had identified a mixed-use property in Dorset: a ground floor retail unit with residential flats above. The property was competitively priced, offering clear value-add potential: the commercial unit was vacant at offer stage, and the residential rents were running below the local market. The client wanted to purchase through an SPV, on a 5-year interest-only basis to maximise cash flow during the initial letting-up period, with no early repayment charges so that refinancing was straightforward once the property's income profile stabilised.

The seller had a related purchase and needed exchange within six weeks.

The challenge

Three factors made this a difficult case for high street lenders. The ground floor commercial unit was vacant. Most semi-commercial lenders prefer, and some require, a let commercial unit with a passing rent. The residential rents were below comparable local levels, which meant the rental stress tests that lenders apply to establish affordability came in lower than the property's actual potential. And the combination of interest-only, no ERCs, and SPV structure ruled out most mainstream products before the vacancy issue was even considered.

Initial approaches to high street lenders confirmed the picture: outright declines on the vacancy, discomfort with the high street retail element in smaller Dorset towns, and where interest was shown, rates that reflected lender uncertainty rather than the strength of the underlying position.

How we structured it

We approached the case as a specialist lending project rather than a standard mortgage application. The client's portfolio of HMOs, MUFBs, student accommodation, and single lets across the South West represented a substantial track record. The SPV sat within a wider portfolio of well-managed assets. That context, presented properly, changes the conversation with the right lender.

We focused on lenders willing to lend on the residential rent alone as the primary debt service, treating the commercial vacancy as a known characteristic of the purchase rather than an unknown risk. We also identified lenders comfortable with SPV structures for portfolio landlords with personal guarantees from the directors.

We secured a Decision in Principle within 48 hours of instruction. This gave the client confidence to proceed, allowed the solicitor to be instructed with funding confirmed, and demonstrated to the vendor that the purchase was viable. We coordinated the valuation, recommending a surveyor with South West mixed-use experience, and managed the legal process against the six-week exchange deadline.

The tracker rate was slightly above what a fixed rate would have been, but the client's priority was no early repayment charges. Locking into a fixed rate for 5 years would have created a financial penalty at the point the client intended to refinance once the commercial lease was established. On a value-add purchase, that flexibility has a real financial value.

What lenders in cases like this need to see is that the residential income alone covers the debt service, and that the borrower has the experience and credibility to execute the letting-up plan. A vacant commercial unit is not a problem. It is a purchasing opportunity. The right lender understands that.
