Holiday Let Due Diligence Checklist Before You Offer

A holiday-let listing can look compelling long before it has been properly tested. A handsome cottage, a strong advertised turnover figure and a popular tourist postcode are not enough to establish whether the investment works. This holiday let due diligence checklist is designed to help you turn an initial opportunity into a decision based on evidence, realistic assumptions and downside protection.

The objective is not to prove that every deal will fail. It is to identify what must be true for the property to produce acceptable cashflow, then check whether those assumptions are defensible before you spend money on surveys, legal work or an offer.

Start with a clear investment brief

Before analysing the property, define what a viable deal means for you. Your required monthly cashflow, deposit, borrowing capacity, acceptable workload and intended holding period all affect the answer. A property that is reasonable for a cash buyer seeking long-term capital growth may be unsuitable for an investor relying on income to cover a mortgage.

Set a maximum total acquisition budget, not merely a maximum purchase price. Include Stamp Duty Land Tax, legal fees, survey costs, mortgage fees, furnishing, safety work, refurbishment, photography and a contingency. A holiday let that needs £25,000 of work is not a £250,000 investment if the purchase price is £250,000.

It also helps to decide early whether you plan to manage bookings yourself or appoint an agent. Self-management can improve the headline margin, but it requires time, local support and a willingness to handle guest communication, changeovers and maintenance issues. Full management reduces that burden, but the fee must be included in the numbers.

Holiday let due diligence checklist: prove the demand

Local appeal is not the same as proven demand for your specific property. Look beyond broad statements such as “close to the coast” or “popular with tourists”. Identify the guest who would book this home, why they would choose it and when they would travel.

Search major booking platforms for comparable properties with the same sleeping capacity, standard, setting and key features. A two-bedroom cottage with parking and a hot tub is not directly comparable with a larger, newly renovated cottage without those features. Note advertised rates, minimum-stay rules, available dates, review volumes and occupancy patterns. A calendar that looks busy may reflect blocked owner dates rather than paid bookings, so treat it as an indication rather than proof.

Seasonality deserves particular attention. Coastal, rural and event-led markets can earn a large share of annual revenue in school holidays and summer weeks. Model monthly occupancy rather than applying one annual average. Ask what happens if peak weeks achieve lower rates, or if shoulder-season bookings are weaker than expected.

Check competing supply as well. New lodge developments, large serviced accommodation operators and high concentrations of short-stay homes can place pressure on rates. Equally, a location with limited suitable accommodation may have stronger pricing power. The point is to test the market that exists now, not the market implied by an agent’s brochure.

Rebuild the income estimate from the ground up

Do not rely on a single gross revenue figure, whether it comes from a seller, agent, booking platform or online estimator. Rebuild your own forecast using a nightly rate and occupancy assumption for each month or season. Then compare it with evidence from genuine local comparables.

If the property has trading history, request as much supporting information as possible. Booking statements, management accounts, VAT records where relevant, historical occupancy, cancelled bookings and details of owner use can reveal whether reported revenue is repeatable. One exceptional year does not necessarily establish a reliable run rate, particularly where pricing was influenced by an unusual event, a new hot tub or a period of restricted travel.

Be explicit about the distinction between gross booking income and money retained by the business. Platform fees, management commission, card charges, cleaning contributions and guest damage deposits can affect what actually reaches you. If cleaning is charged to guests, confirm whether it covers the full cleaning and laundry cost rather than assuming it is profit.

A sensible base case should be credible without being optimistic. Then run a downside case with lower occupancy and reduced average nightly rates. If the deal only works at the top end of every assumption, it is not yet a resilient deal.

Build a full operating-cost schedule

Holiday lets carry a wider range of operating costs than many first-time buyers expect. Some vary with bookings, while others continue whether the property is occupied or not. Your model should show both.

Include utilities, broadband, council tax or business rates, insurance, cleaning, laundry, consumables, repairs, gardening, waste collection, linen replacement, platform fees, management fees, accountancy, marketing and a reserve for furniture and appliance replacement. Hot tubs, electric heating, private drainage, swimming pools and remote locations can materially increase costs.

For properties with a garden, land or a shared private road, establish exactly who is responsible for maintenance. Service charges should not be treated as fixed simply because they appear in a sales pack. Ask for recent statements, planned works and any history of special levies. Older buildings can also carry recurring costs for damp treatment, roof repairs, heating systems and drainage that are easy to underestimate from photographs.

Model maintenance as a realistic annual allowance, not as zero until something breaks. Guest use is harder on furniture, bathrooms, locks, mattresses and kitchen equipment than normal residential occupation. A reserve will not prevent repairs, but it stops every repair from appearing as a surprise.

Check planning, permissions and local restrictions

A desirable location does not automatically permit unrestricted short-term letting. Ask your solicitor to investigate the title, planning history and any restrictive covenants. Leasehold flats and some holiday complexes may prohibit short stays, require consent or impose rules that make the business impractical.

Planning requirements vary by location and property type. In England, rules can be affected by local planning policy, Article 4 directions and the established use of the property. Wales and Scotland have different approaches, with licensing and planning controls particularly relevant in some areas. Do not assume that a property currently advertised as a holiday let has every required permission in place or that its current operation can simply continue after purchase.

Check whether there are occupancy conditions attached to a holiday park, lodge or converted barn. These can limit use to holiday occupation, prevent permanent residence, restrict winter stays or specify who may occupy the property. Such conditions can affect lender appetite, resale options and personal use.

Tax treatment also needs current professional advice. The former Furnished Holiday Lettings tax regime was abolished from April 2025, so do not build a purchase decision around outdated claims about reliefs or pensionable earnings. Consider whether turnover could approach the VAT registration threshold and confirm the likely treatment of council tax, business rates and any local reliefs with the relevant authorities.

Inspect the property as an operating business

A standard survey remains valuable, but assess the building through a guest-operating lens too. Is there reliable parking, safe access in poor weather, adequate water pressure, workable heating and dependable mobile signal or broadband? A beautiful rural cottage may still generate poor reviews if guests cannot arrive easily, dry clothes, charge an electric vehicle or use the Wi-Fi.

Examine storage carefully. You need space for linen, cleaning materials, replacement consumables, owner belongings and maintenance tools without compromising the guest experience. Check fire safety provisions, electrical condition, gas safety where applicable, alarms, emergency access and the practical route for cleaners between bookings.

Furniture and décor should also be costed honestly. A listing may photograph well but require immediate spending on beds, sofas, cookware, blinds or outdoor seating to compete at the assumed nightly rate.

Stress-test finance and break-even occupancy

Obtain finance terms early, particularly where the property is unusual, leasehold, on a holiday park or subject to occupancy restrictions. Specialist holiday-let mortgages may have different affordability tests, deposit requirements, personal-use conditions and interest rates from buy-to-let lending.

Calculate break-even occupancy using your annual fixed costs, variable cost per booked night and realistic average nightly rate. This tells you the proportion of sellable nights required to cover operating costs and finance payments. It is generally more useful than a headline gross yield because it makes the pressure points visible.

Test at least three cases: a base case, a weaker-demand case and a higher-cost or higher-interest-rate case. If mortgage payments rise at remortgage, can the property still cover itself? If annual revenue falls by 20 per cent, what happens to cashflow? A deal does not need to be immune to every setback, but you should know where the margin disappears.

Holiday Let Investor’s deal-analysis approach is built around making these assumptions visible. The value is not in producing a flattering spreadsheet result. It is in seeing which assumptions must hold true before you commit.

Make the offer conditional on evidence

By the time you are ready to offer, you should be able to explain the deal in plain terms: expected revenue, operating costs, finance costs, break-even occupancy, likely risks and the evidence behind each figure. Where evidence is weak, either use a more conservative assumption, negotiate the price or walk away.

The best holiday-let purchase is rarely the one with the most exciting projected turnover. It is the one that still looks sensible after you have allowed for the quieter months, the overlooked costs and the fact that property investing does not reward assumptions simply because they were convenient.
