Short-let property occupies an awkward space in the lending market. It is not quite buy-to-let, because the income is seasonal and comes from a stream of short occupancies rather than a tenancy. It is not quite commercial, because the building is usually residential. And it is not quite a second home, because it trades.
That in-between status is why owners often find their first few funding conversations unproductive, and why the right structure depends heavily on how the property is actually used.
Why Lenders Treat It Differently
A buy-to-let lender assesses a property against a tenancy: a known monthly rent, from a known tenant, on a contract. The calculation is simple and the income is contracted.
A holiday let has none of that. Income arrives in peaks and troughs, occupancy varies with weather, events and the wider economy, and there is no tenant on a twelve-month agreement. From an underwriting perspective the property is closer to a small trading business than to a rental.
Lenders respond in one of three ways. Specialist holiday let lenders assess projected income, usually taking an average across low, mid and high season rather than annualising peak weeks. Commercial lenders treat larger or multi-unit operations as trading businesses and look at the accounts. And a number of mainstream buy-to-let lenders simply decline, because short-letting breaches their standard mortgage conditions.
That last point deserves emphasis: letting a property on short lets while it sits on an ordinary buy-to-let mortgage is very often a breach of the mortgage terms. Owners drift into this without realising, and it is not a technicality — it can trigger a demand for repayment.
What Lenders Want to See
Where a specialist lender is assessing projected income, the quality of your evidence makes a material difference to the outcome.
A professional projection from a recognised holiday letting agency carries far more weight than your own spreadsheet. Comparable evidence from similar properties in the same location is better still. If the property has a trading history, twelve months of actual booking data will beat any projection.
Lenders also look closely at location and seasonality. A coastal cottage with a genuine twenty-week season is assessed differently from a city apartment with steady year-round corporate demand. Neither is inherently better, but the risk profile differs and the terms will reflect that.
Expect a lower loan-to-value than on standard buy-to-let, and expect the lender to want comfort that you could cover the payments through a poor season.
Buying and Converting
Most short-let projects involve work. A property bought as a standard house rarely functions as a serviced apartment without reconfiguration, and the standard of finish that drives nightly rates is well above ordinary rental specification.
Where the property needs work before it will trade — or before it will meet a long-term lender’s condition requirements — the usual sequence is short-term finance to acquire and refurbish, followed by a refinance onto a holiday let or commercial mortgage once the property is operating and there is some income evidence.
Funds can be released in stages against current value, with further tranches as work completes and value is added. Our bridging refurbishment finance page explains how staged facilities work, and the bridging loans pillar covers eligibility and terms more generally.
Where the plan is to buy, convert and then hold on a long-term facility, a combined structure that bridges the purchase and rolls into the term loan can be more efficient than arranging two facilities separately — the principle is the same as the one set out on our bridge-to-let finance page.
The Regulatory Layer
Short-letting attracts more local regulation than ordinary renting, and the position has been tightening in several parts of the UK.
Depending on where the property is, you may need a licence to operate a short-term let, planning permission for a change of use, or both. Some local authorities operate registration schemes. Some blocks of flats prohibit short-letting outright in the lease, which no amount of licensing will overcome.
This matters to a lender as well as to you. A facility advanced against projected short-let income, on a property that turns out not to be permitted to short-let, leaves everyone in a poor position. Establish the position before you commit, not after.
The lease point catches people particularly often. A leasehold flat with a covenant against business use, or against letting for periods under six months, cannot lawfully be run as a serviced apartment regardless of what the local authority permits.
Larger Operations and Multi-Unit Portfolios
Once you are running several units, the assessment shifts. Lenders begin treating the operation as a trading business rather than a collection of properties, looking at accounts, occupancy rates, average daily rate and the management arrangement.
At that point commercial rather than residential lending is often the better fit, with facilities structured against the business’s income rather than each property individually. Our commercial property finance pillar covers those structures. Where the units are held individually but financed together, a portfolio arrangement may work better — see our portfolio mortgage page.
Frequently Asked Questions
Can I use an ordinary buy-to-let mortgage for a holiday let?
Almost never. Standard buy-to-let terms typically require an AST and prohibit short-term letting. Operating outside those terms puts you in breach of the mortgage, so a specialist holiday let or commercial facility is the correct route.
How do lenders assess income on a property with no trading history?
Through a projection, ideally prepared by a recognised letting agency and supported by comparable evidence from similar local properties. Lenders generally apply their own discount to projected figures rather than taking them at face value.
Is finance available for a property that isn’t yet converted?
Yes — short-term facilities are assessed on current value and the exit plan rather than on the property’s eventual use, which is what makes conversion projects fundable before they trade.
What happens if occupancy falls short of projections?
That is your risk rather than the lender’s, and it is the main reason loan-to-values are more conservative here than in standard buy-to-let. Building a margin into your own numbers, rather than financing against a best-case season, is the sensible discipline.
