Cambridge — security property
An experienced property company identified an opportunity to convert a former local authority house in Cambridge into a high-yield five-bedroom HMO. Many lenders won't touch a project involving a full change of use and structural alterations. AF Credit structured a refurbishment bridging loan that funded both the purchase and the conversion works — with a day-one LTV of 57.8% and a projected GDV of £550,000.
Cambridge — security property
A full HMO conversion — room separation, four bathrooms, ensuite kitchenettes and a garage extension — fell outside the appetite of mainstream and buy-to-let lenders. The change of use and scale of works meant standard property finance was not available.
AF Credit structured a refurbishment bridging loan secured against the property at 57.8% LTV, allowing the borrower to complete the purchase and fund the conversion programme. The borrower contributed over £300,000 of equity, keeping the lending structure conservative throughout.
£210,000 facility arranged. Purchase completed. Conversion from two bedrooms to a five-bedroom HMO underway, with an estimated GDV of £550,000 and projected annual rental income of approximately £51,000 — a significant uplift on the pre-works value.
Cambridge's rental market is among the strongest in the UK — driven by the university, the research and technology sector, and a large professional population that is priced out of homeownership. For an experienced property company with the right project, a well-executed HMO conversion in Cambridge can generate yields that are difficult to achieve through standard single-let investments.
The borrower had identified a two-bedroom former local authority house that represented exactly this kind of opportunity. At a purchase price of £425,000, the property was undervalued relative to its post-works potential. The proposed conversion — separating the house into five letting rooms with ensuite facilities and kitchenettes, and extending into the existing garage to create additional space — was projected to push the GDV to £550,000 and generate approximately £51,000 per annum in rental income once fully tenanted.
The challenge was finance. Mainstream buy-to-let lenders won't fund a property that is changing use, under active refurbishment, or that will end up as an HMO rather than a standard single-let. The scale of the planned works — four bathrooms, ensuite kitchenettes, a garage extension and a full modernisation — placed this well outside any standard residential product. Several lenders declined without engaging with the project's fundamentals.
This was not a light cosmetic refurbishment. The conversion programme involved structural and fit-out works that fundamentally changed the layout and use of the property:
Projects of this scope are exactly what refurbishment bridging finance is designed for. The borrower's own capital funded the works directly, while the AF Credit facility funded the acquisition and was structured around a realistic timeline for the conversion to complete.

Mainstream buy-to-let and residential mortgage lenders assess a property's current condition and use. For an HMO conversion, the property during the works is neither a standard residential home nor a functioning HMO — it is somewhere in between, undergoing a fundamental change that most lenders have no appetite to fund.
Bridging finance works differently. A specialist lender assesses the post-works value, the borrower's experience and the exit strategy — and structures finance around the project rather than the property's current state. In this case, five factors made the deal work:
AF Credit arranged a £210,000 refurbishment bridging loan to fund the acquisition of the property, with the borrower contributing over £300,000 of their own capital to keep the day-one LTV at a conservative 57.8%. The facility provided sufficient time to complete the full conversion programme before refinancing onto a specialist HMO mortgage or selling the completed asset.
This is a textbook example of what refurbishment bridging finance is for. The project had compelling fundamentals — a strong location, a conservative LTV, substantial borrower equity, an experienced company and two clear exit routes. The reason it required specialist finance was not that it was risky. It was that the change of use and works programme meant it did not fit the criteria of lenders who underwrite against current condition alone.
Bridging finance, structured around what the property will be rather than what it currently is, unlocked a project that will generate £51,000 per annum once tenanted — a return that a two-bedroom local authority house in the same location could not have achieved.
Frequently Asked QuestionsYes. Specialist bridging lenders can fund HMO conversions where a standard residential property is being converted into a house in multiple occupation. The key factors are the borrower's experience, the loan-to-value against current or post-works value, and a credible exit strategy — typically a specialist HMO mortgage or sale of the completed asset. AF Credit regularly funds HMO conversion projects that fall outside mainstream lender appetite.
An HMO refurbishment bridging loan is short-term finance used to purchase and convert a property into a house in multiple occupation. It covers both the acquisition and the refurbishment works — including room separation, bathroom installation, kitchenette fitting and any structural alterations. The bridge runs for a defined term, at the end of which the borrower refinances onto a specialist HMO mortgage or sells the completed asset.
Mainstream lenders typically won't fund HMO conversions because the property changes use during the works, the security is uninhabitable or partly habitable during the project, and the income model is based on multiple tenants rather than a single household. Specialist bridging lenders assess the post-works value and exit strategy rather than the current condition, which is what makes bridging finance appropriate for this type of project.
LTV for an HMO bridging loan depends on the nature of the project. On a straightforward conversion with an experienced borrower, lenders can typically reach 65–75% of current value or up to 70% of GDV on a staged drawdown basis. In this case, the borrower kept day-one LTV at 57.8% by contributing over £300,000 of their own equity, which supported a conservative lending structure and a smooth credit approval.
Yes, most specialist HMO mortgage lenders require an HMO licence to be in place before they will complete a refinance. Mandatory HMO licensing applies to properties let to five or more people forming more than one household. Some lenders will proceed on the basis of a licence application being in progress, but it is best to allow time within the bridge term to obtain the licence before refinancing.
Yes. Property companies and limited companies are common borrowers for HMO bridging loans. AF Credit lends to both individuals and companies for HMO conversion projects. The assessment focuses on the directors' experience, the company's track record and the strength of the underlying deal.
The most common exit strategies are: refinance onto a specialist HMO buy-to-let mortgage once works are complete and the property is tenanted, or sale of the completed, fully tenanted HMO as an investment. In this case, the borrower had both options available — the completed income-producing HMO was well-positioned for either route.
GDV stands for gross development value — the estimated market value of the completed, fully converted and tenanted HMO. In this case, the GDV was estimated at £550,000 against a purchase price of £425,000 — a significant uplift driven by the conversion to five letting rooms generating approximately £51,000 in annual rental income.
