You have found the property. You have run the numbers and they work. You go to your bank, or to a comparison site, and you discover that the mortgage you assumed you would get does not exist.
This is the single most common surprise for people buying their first holiday let, and it stops a good number of purchases before they start. It is not a reflection on you, your deposit or the property. It is a structural feature of the UK mortgage market, and the good news is that it is entirely solvable once you understand what is actually happening.
Why the High Street Says No
Three things make a holiday let awkward for a mainstream lender, and none of them are about risk in the way people assume.
1. There is no tenancy agreement to look at
A buy to let mortgage is assessed against a contract. There is a tenant, a term and a monthly figure, and a lender can model the whole thing on a spreadsheet.
A holiday let has none of that. It has a projected calendar of bookings that do not exist yet, at prices that change nightly, from guests who have not booked. That is a perfectly sound business, but it is not the shape of information a standard underwriting process is built to handle.
2. The income is seasonal, and seasonality looks like risk
A property that earns most of its money in twelve weeks of the year and very little in February is normal in this sector and alarming in a lender's standard affordability model. Assessing it properly means understanding tourism patterns in a specific location, which is specialist knowledge most mainstream lenders have no reason to build.
3. Standard products often prohibit it outright
This is the one that catches people who try to proceed anyway. Most residential and buy to let mortgage conditions restrict letting the property on short-term agreements. Letting a property on Airbnb against a standard buy to let product is not a grey area, it is usually a breach of your mortgage terms, and it can put your insurance in the same position.
What to check: if you already own a property and are thinking of converting it to short-term letting, read your existing mortgage conditions before you take a single booking, and speak to a broker about the right product.
What a Specialist Lender Assesses Instead
Specialist holiday let lenders do exist, and they assess the same property completely differently. Rather than a tenancy, they look at what the property is likely to earn as a holiday let, usually supported by a projection from a letting agent or a comparable assessment, and at your wider position.
Most of them are smaller building societies and specialist lenders. Many do not lend directly to the public at all, which is why buyers who go looking on their own so often conclude that nobody will lend to them. The lenders are there, they are simply not on the comparison sites.
What to check: deposit expectations are typically higher than for a residential purchase, and criteria vary widely between lenders, so the right question is not "will someone lend?" but "which lender fits this property and this buyer?". That is a broker question rather than a search engine question.
The Part You Can Actually Control
You cannot change how lenders assess seasonality. You can change the quality of what you put in front of them, and this is where most first-time buyers lose ground unnecessarily.
Model the net, not the headline
The nightly rate on a comparable listing is not what lands in your account. Between the two sit the platform commission, the payment processing and, in many cases, the cleaning fee, which is money passing through you rather than money you have earned. A projection built on gross booking value overstates the income before a single cost has been counted.
Do not price the whole year in August
The most common error by a distance. Taking a peak nightly rate and multiplying by three hundred and sixty five produces a number that will never happen and immediately signals inexperience. Seasonality is not a problem to be solved, it is the shape of the business.
Count the changeover properly
Cleaning is a per-booking cost, not a monthly one. A property taking lots of two and three night stays gets cleaned far more often than one taking weekly lets at the same occupancy. Add linen, consumables and the laundry, and the number gets meaningful quickly.
Include your own use, honestly
Most people buying a holiday let intend to use it, and there is nothing wrong with that. But the weeks you will want are usually the weeks that earn most. Take them out of the projection at the time of year you will actually take them.
Have an answer for who runs it
Somebody has to answer guest enquiries quickly, set the nightly price and keep changing it, clean between every stay, and be reachable when something breaks. There are three honest answers: you do it, a management company does it for a percentage, or you keep control and automate the routine work. Zugrow covers that last option, handling guest messaging, nightly pricing and channel management across Airbnb, Booking.com, Vrbo, Expedia and Google for a fixed monthly cost, which has the useful side effect of being an easy line to put in a projection.
Whichever you choose, cost it. A projection showing a healthy income and no idea who is cleaning the property has a hole in it that an underwriter will find.
Specialist Holiday Let Mortgage Brokers
Because most specialist lenders in this market do not deal directly with the public, a broker is not an optional convenience here in the way it might be for a residential purchase. It is usually the only route to the products that exist.
A specialist broker dealing solely with holiday let finance, with access to whole of market holiday let lenders including deals not available elsewhere. Over eight years in the sector and more than 1,100 holiday let mortgages submitted, worth over £200 million, including cases mainstream brokers have been unable to place. Their specialisms cover furnished holiday lets, limited company purchases, complex and self-employed income, portfolio landlords and multi-unit properties. Unusually for a broker, the team have been holiday let owners and operators themselves, so the conversation tends to be about the business as well as the mortgage. A free initial assessment and a borrowing calculator are available on the site.
They have also written up the lender's side of this in detail. If you are at the stage of putting figures together, their guide to what lenders want to see in a holiday let business plan walks through how the income projection is assessed, what deposit and personal income levels tend to be expected, and the reasons applications get turned down.
Conclusion: The Refusal Is Not the Answer
Being turned down by a high street lender feels like a verdict on your plan. It is not. It is a verdict on the product you happened to apply for, from an institution that does not write mortgages for this kind of property.
The lenders that do exist will look at the same property and the same buyer and see a business rather than an anomaly. What they will want is a projection that is realistic, a set of costs that shows you have thought it through, and a clear answer to who is going to run the place. Two of those three are entirely within your control before you ever speak to anyone.

Frequently Asked Questions
Can I buy a holiday let with a normal buy to let mortgage?
No. A standard buy to let product is written on the assumption of a tenant on a long-term agreement, and short-term letting usually breaches its terms. Using one for a holiday let can put you in breach of your mortgage conditions.
Why do high street lenders say no?
Because the income is seasonal, variable and unevidenced at the point of purchase. A tenancy agreement is a contract a lender can assess. A projected booking calendar is not, so most mainstream lenders decline rather than build the expertise to assess it.
So who does lend?
A relatively small group of specialist lenders, many of them building societies, most of which do not deal with the public directly. In practice you reach them through a broker who specialises in holiday let finance.
What will I need that a normal purchase does not require?
A larger deposit than a residential purchase, an income projection the lender can work with, and a clear answer to how the property will actually be run.
I already own the property. Can I just start letting it short-term?
Check your mortgage conditions first, and your insurance. Most residential and buy to let terms restrict short-term letting, and letting anyway can put you in breach of both. Speak to a broker about switching to the right product before you take a booking.
Does using a management company or software affect my application?
It affects your numbers, which is what a lender is assessing. A management fee comes straight off your net income and needs to be in the projection. Whichever route you take, cost it honestly rather than leaving it out.
