Buying a Property That Needs Converting Before You Can Let It

Why a holiday-let lender will not fund a conversion, and how a two-stage bridge-to-let structure solves it.

It is a common and understandable plan: find a property with potential, buy it, convert it, and let it out as a holiday home. The difficulty is that the finance rarely works the way people expect.

A buyer will often assume they can simply take out a holiday-let mortgage, complete the purchase, and carry out the conversion afterwards. In practice that sequence is the wrong way round, and understanding why saves a great deal of wasted time and cost.

Why a holiday-let lender will not fund a conversion

The single most important structural point comes before any of the finer detail, because it shapes everything else.

Holiday-let mortgage lenders, and term lenders more generally, will not lend against a property that needs a material level of work. They lend against a property that is complete, habitable, immediately lettable and not being converted.

A conversion falls squarely outside that.

If a property needs to be converted before it can be occupied and let, it does not meet the condition a holiday-let lender requires on day one. This is not a matter of persuasion or presentation; it is a fixed feature of how these products are underwritten.

Trying to force a conversion project through a standard holiday-let application simply results in a decline.

The two-stage structure that does work

The correct route, and often the only viable one, is to split the finance into two stages that are designed to work together:

  1. Stage one, bridging finance. A short-term facility funds the purchase and the refurbishment works. Bridging finance is built for property that is unfinished or needs works, so it fits where a term lender cannot.
  2. Stage two, the holiday-let mortgage. Once the works are complete and the property is habitable and lettable, a holiday-let mortgage is taken out, and it repays, or exits, the bridging finance.

TermShort term, typically months, while the works are carried out.Longer-term mortgage assessed on projected letting income.
Cost profileHigher interest, plus lender and arrangement fees.Standard holiday-let pricing once the property qualifies.

Be clear-eyed about the cost

It is only fair to be candid that this route is not cheap.

Bridging finance carries higher interest rates than a term mortgage, along with lender and arrangement fees. Because there are two stages, you will also incur two sets of legal and valuation costs across the project.

None of this makes the approach wrong; for a conversion it is usually the correct and only workable structure. But the total cost of finance needs to be built into your figures from the very start, not treated as an afterthought, so that the numbers still stand up once every fee is accounted for.

The point that catches people out: costings for the works

One issue surprises many buyers, so it is worth raising early. A bridging lender will require independent, professional costings for the refurbishment.

If you or a family member happen to be in the trade and can carry out the work at considerably lower cost, that is a real advantage to your actual spend, but it makes no difference to how the lender assesses the project.

The reason is straightforward. If the project were to fail and the lender had to repossess a part-finished property, they would need to bring in a contractor to complete the works at the going commercial rate.

They therefore underwrite against that commercial cost, not against what you can achieve in-house. Your own trade skills genuinely help you in practice, but they will not reduce the figure the lender works to.

Lining the exit up from the outset

The two pieces of a bridge-to-let project are not independent. The whole structure depends on the exit, the holiday-let mortgage that repays the bridge, being achievable once the works are done.

A bridge with no clear exit is a serious risk, because the short-term facility has to be repaid whether or not longer-term finance is in place.

That is why the exit should be considered at the very beginning, not left to chance at the end. The sensible approach is to establish that the completed property will qualify for a holiday-let mortgage before the bridge is drawn down, so the finish line is defined before the race begins.

How Drake would take this forward

For a project like this we structure the two stages so they work together.

We handle the holiday-let exit, the longer-term mortgage that repays the bridge once the works are complete, directly. For the short-term bridging facility we refer you to our bridging specialist, who gathers the necessary information and puts together the short-term finance.

The two are coordinated deliberately, so the exit is lined up from the outset rather than left to chance. Once the bridging specialist has the detail in hand, we assess the holiday-let exit alongside it, giving you a single, joined-up plan rather than two disconnected applications.
