A strong booking calendar isn't the income a holiday let lender will actually use.
Lenders average low, mid and high season letting income — and some fall back on standard tenancy rent. Occupancy assumptions decide more than the listing.

What's driving the holiday-let mortgage?
How your case is assessed
How lenders assess a holiday let
Holiday let lending is a specialist niche, dominated by a smaller group of lenders who each take a different view of seasonal income and how the property will be used.
How seasonal income is averaged
Most lenders take low, mid and high season weekly rates and average them across an assumed number of let weeks — commonly around 30. Some also require the figure to work on a standard tenancy basis as a floor.
Evidence the lender will accept
A holiday letting agent's projection carries far more weight than your own forecast. On a refinance, actual booking history and accounts strengthen the case considerably.
Location, property type and demand
Established holiday areas support the assumptions more easily. Unusual construction, annexes, park homes and properties with holiday-use planning restrictions narrow the panel sharply.
Personal use and letting rules
Most lenders allow limited personal use, and some cap it explicitly. Letting to family, extended personal occupation or leaving the property empty can breach the mortgage terms.
You don't need to guess which holiday let lenders fit — we model the seasonal assumptions and evidence requirements before any hard search.
Specialist insight
Not every lender treats short-term letting the same way
First holiday let · optimistic forecast · unusual property
Higher challenge
Narrower specialist panel · agent projections expected · standard tenancy fallback can cut borrowing well below the booking forecast.
Established area · evidenced letting history · sensible loan-to-value
More lender choice
Broader holiday let panels · seasonal averaging accepted · clearer path when location, evidence and deposit line up.

“People show me a booking calendar and assume the lender will read it the same way. Most won't — they average the seasons, and some fall back on what the property would earn on a standard tenancy.”

Lived experience
Mistakes we repeatedly see
Not theory — patterns that keep showing up when buyers plan the borrowing around peak-season nightly rates.
Budgeting on high-season rates all year
Lenders average across the seasons and assume void weeks. A forecast built on August pricing rarely survives the assessment.
Letting short-term on a standard buy-to-let mortgage
Most buy-to-let mortgages require an assured shorthold tenancy. Short-term letting without the right product can breach the terms of the mortgage.
Forgetting how much the running costs take
Cleaning, changeovers, agent commission, utilities, insurance and maintenance are all on you in a holiday let. Gross booking revenue is not profit.
Assuming the old tax treatment still applies
The furnished holiday lettings tax regime ended in April 2025, so holiday lets are now taxed broadly like other property businesses. Cases built on the old reliefs need revisiting with your accountant.
Overlooking local licensing and planning rules
Short-term letting rules vary across the UK and some areas restrict or license it. A property you can't legally let as you planned is a very expensive asset.
Real client scenarios
How we've helped holiday let owners
Based on genuine cases we've helped with. Personal details have been changed to protect privacy.
Optimistic forecast, realistic funding
- Coastal cottage
- Agent projection
- Seasonal averaging
- Purchase funded
Situation
Buyer planned borrowing around peak-season weekly rates from comparable listings.
Challenge
Averaged across low, mid and high season with assumed void weeks, the assessed income supported materially less borrowing than expected.
What changed
Obtained a holiday letting agent's projection, matched a lender whose averaging method suited the property, and adjusted the deposit to bridge the gap.
Outcome
Purchase completed on assumptions that held at underwriting.
Why it worked
We used the lender's arithmetic from the start, so nothing had to be renegotiated after the valuation.
Short-term letting on the wrong mortgage
- Existing BTL
- Airbnb letting
- Product switched
- Terms compliant
Situation
Landlord had begun letting a buy-to-let property on short-term bookings for better returns.
Challenge
The existing mortgage required an assured shorthold tenancy — the letting pattern breached the terms and put the mortgage at risk.
What changed
Refinanced onto a proper holiday let product with a lender comfortable with short-term bookings and the actual usage pattern.
Outcome
Higher income retained, on a mortgage that permits how the property is let.
Why it worked
We fixed the compliance problem rather than hoping it went unnoticed — and the pricing difference was smaller than the risk.
Second home turned into a holiday let
- Existing second home
- Personal use retained
- Specialist lender
- Refinanced
Situation
Owners wanted to let their second home to visitors for part of the year while still using it themselves.
Challenge
Their residential second-home mortgage didn't permit letting, and most holiday let lenders cap personal use.
What changed
Placed with a lender that allows a defined level of owner occupation alongside commercial holiday letting, with income evidenced by an agent.
Outcome
Letting income achieved without breaching the mortgage or losing personal use.
Why it worked
We read the personal-use criteria before choosing the lender — the detail most comparison tables never show.

Before you enquire
What we'll ask you on the first call
Straightforward questions — no hard credit search at this stage.
- Where the property is, and whether it's an established holiday letting area
- Expected low, mid and high season weekly rates — and where those figures come from
- How much personal use you want, and whether family will stay there
- Deposit available, and whether you're buying personally or through a company
Advisory promise
When we might tell you to wait
We won't always tell you to apply today.
We may advise waiting where the income forecast can't be evidenced by a letting agent, where local licensing or planning rules would restrict how you intend to let, or where a season of actual booking history would materially improve both the borrowing and the pricing.
If evidencing the income first or adjusting the letting plan would meaningfully widen options, we'll say so before another footprint goes on your file. We give advice — not just applications.

Common questions about holiday let mortgages
Our promise
What we'll never do
- Tell you to apply if it won't work
- Send applications everywhere
- Recommend borrowing beyond your budget
- Hide bad news
We don't chase the cheapest holiday let rate. We make sure the income assumptions behind your borrowing will survive underwriting.
Find out what a holiday let lender will accept
Tell us the property, the location and how you plan to let it — we'll assess what's realistically possible before you commit.
We don't recommend a lender until we know how they average seasonal income, what evidence they'll accept and how much personal use they allow.
The gap between an optimistic booking forecast and a lender's assessed income is where holiday let deals fail. Better to find it now than after the survey.
