What is the difference between a holiday let and a buy-to-let mortgage?
A standard buy-to-let mortgage funds a property let long-term to a single household on an assured shorthold tenancy, and is assessed on the steady monthly rent. A holiday let mortgage funds short-term or serviced accommodation let to holidaymakers, and is assessed on projected seasonal income across low, mid, and peak seasons. The two are underwritten differently, carry different deposit and rate expectations, and are offered by different lenders. Assesr packages both into a lender-ready credit paper in around 60 seconds and matches you to the right specialist lender.
How is income assessed on each?
This is the core difference:
- Standard BTL uses the interest coverage ratio on a single monthly rent figure, stressed at a set interest rate. It is predictable and easy to model — see our overview of buy-to-let finance.
- Holiday let uses projected nightly or weekly income across low, medium, and high seasons, usually evidenced by a letting agent's projection or actual booking history. Lenders blend the seasons to arrive at a sustainable income figure.
Because holiday income is variable, holiday let lenders build in more caution, which shows up in deposit and rate.
What deposit and LTV apply?
Standard BTL is typically available up to 75% LTV. Holiday let mortgages often require a slightly larger deposit — commonly 25% to 30% — reflecting the perceived variability of seasonal income. A strong, evidenced income projection or a track record of good occupancy can improve the terms available.
How does tax differ?
Holiday lets that meet the qualifying conditions have historically been treated differently from standard rentals for tax, with rules around minimum availability and actual letting days. The tax landscape for furnished holiday lettings has been changing, so the treatment of expenses, mortgage interest, and capital allowances may differ from a standard BTL and is subject to reform. This is an area where professional tax advice is essential — do not assume the old furnished-holiday-let advantages still apply. On the standard BTL side, individual landlords face the Section 24 interest-relief restriction covered in our limited-company buy-to-let guide.
Which running costs should you budget for?
Holiday lets are more operationally intensive than a long-term rental:
- Cleaning and changeovers between every guest stay.
- Marketing and platform fees for booking sites.
- Management, if you use an agency to handle bookings and guests.
- Higher voids in the low season and between bookings.
- Furnishing and consumables to a hospitality standard.
A long-term BTL, by contrast, has one tenant, lower turnover, and simpler management — but usually lower gross income per night.
Which should you choose?
It comes down to location and strategy. Holiday lets can outperform in tourist destinations with strong seasonal demand, where nightly rates far exceed the equivalent monthly rent. Standard BTL suits areas with steady long-term tenant demand and investors who want predictable, hands-off income. A high-yield city with strong rental demand may favour long-term letting — see our Liverpool buy-to-let guide — while a coastal or rural tourist hotspot may favour holiday letting. Some investors run a mix across a portfolio.
How Assesr helps with holiday let and buy-to-let finance
Assesr builds a lender-ready credit paper in around 60 seconds for both holiday let and standard buy-to-let, models the relevant income assessment (seasonal projection or monthly rent stress test), and matches you to specialist lenders for each — including SPV, HMO, MUFB, and portfolio. We charge a quarter of the typical broker fee: the 0.5% Assesr Fee, payable on drawdown, with nothing until completion. Assesr covers unregulated buy-to-let and holiday let in the UK; consumer BTL is out of scope, and we do not give tax advice.
Frequently asked questions
What is the difference between a holiday let and buy-to-let mortgage?
A standard buy-to-let mortgage is for long-term letting to a single tenant on an assured shorthold tenancy, assessed on the monthly rent. A holiday let mortgage is for short-term or serviced accommodation let to holidaymakers, assessed on projected seasonal income across low, medium, and high seasons.
Do holiday lets need bigger deposits?
Holiday let mortgages often require a slightly larger deposit than standard buy-to-let, commonly 25% to 30%, because seasonal income is considered less predictable. The exact requirement depends on the lender and the strength of the projected income.
Is a holiday let more profitable than a buy-to-let?
It can be, because nightly holiday rates often exceed the equivalent monthly rent, but income is seasonal and variable, and running costs (cleaning, management, marketing, voids) are higher. Profitability depends heavily on location, occupancy, and how actively it is managed.
