We Analysed a £325,000 Cornwall Holiday Let: Income, Costs and Offer Risk
Important note on this worked example
This is an illustrative worked example, not a forecast, valuation, recommendation or statement that a specific property will perform in this way. The figures below are labelled as assumptions so the method is clear.
Holiday Let Investor provides educational tools and decision-support resources. It does not provide financial, mortgage, tax, legal, planning, valuation or investment advice. Lending terms, tax treatment, planning status, local restrictions, insurance, licensing and property condition should be checked with qualified professionals before a buyer relies on any model.
Quick answer
A £325,000 Cornwall holiday let can look attractive on a headline income forecast, but the investment case can change materially once management, cleaning, maintenance, setup spend and finance costs are added. In the illustrative base case below, the property only has a narrow post-finance margin. In the stress case, a lower booking income and higher finance cost move the example into negative annual cashflow.
The useful question is not "Can a Cornwall holiday let earn good gross bookings?" The useful question is "What evidence supports the income, what costs have been included, and what offer price still works if the assumptions weaken?"
The workflow is:

The £325,000 Cornwall holiday let scenario
For this article, we are modelling a fictional Cornwall holiday let with a £325,000 purchase price. The aim is to show how a buyer might test the numbers before relying on an agent forecast, making an offer, paying for a survey, or treating the property as a serious acquisition.
The example assumes a small coastal or near-coastal property with enough guest appeal to produce bookings, but not enough evidence yet to treat the income as proven. This is a Cornwall holiday let investment example, not a Cornwall area guide. A forecast is a starting input. It is not profit, certainty, or a substitute for comparable data, booking history, cost evidence and professional checks.
Illustrative property assumptions
| Input | Illustrative assumption | Why it matters |
|---|---|---|
| Purchase price | £325,000 | Sets capital requirement and finance pressure |
| Property type | 2-bedroom holiday let | Drives guest capacity and comparable selection |
| Guest capacity | 4 guests | Affects pricing, cleaning, wear and occupancy |
| Location | Cornwall, near established visitor demand | Relevant to income evidence, seasonality and restrictions |
| Condition | Presentable but not fully optimised | May require setup and launch spend |
| Parking | Assumed available | Can affect booking strength and comparables |
| Management route | Full-service agency in base case | Material impact on net income |
| Setup budget | £30,000 | Furniture, photography, launch, safety/admin and working capital |
| Finance structure | Illustrative 75% loan-to-value | Must be checked with a broker or lender |
These assumptions are intentionally ordinary. Many buyers are not choosing between obvious bargain and obvious failure. They are judging a property that looks plausible but needs evidence.
Start with the calculator
recreate this starting case in the Holiday Let Calculator before treating the asking price as viable.
Income evidence: what we would verify first
The first weak point in many holiday-let investment models is the gross income number. A listing may show a projected annual booking figure. An agent may provide a rental estimate. A seller may share historic bookings. A local manager may quote an achievable range.
The strongest income evidence usually comes from actual booking history for the same property, with rates, occupancy, deductions and owner statements reconciled. The weakest evidence is an unsupported estimate based on broad local demand.
For a £325,000 Cornwall holiday let, the income review should start with these questions:
- Is the forecast based on this exact property or on comparable properties?
- Are the comparables similar in bedroom count, location, quality, parking, pet policy and guest capacity?
- Does the forecast separate peak season, shoulder season and low season?
- Does it include or exclude cleaning fees?
- Are platform fees, agency fees and VAT treatment clearly separated?
- Is the property assumed to be available all year?
- Are there local rules, planning constraints, lease terms, mortgage conditions or insurance limits that could affect holiday-let use?
For the worked model, we will use an illustrative gross booking assumption of £38,000 per year, excluding cleaning fees. This is not a claim that a Cornwall property at this price should or will earn £38,000. It is a modelling input to test.
Income evidence table
| Evidence item | Current status in this example | Confidence | Follow-up before offer |
|---|---|---|---|
| Actual booking history | Not supplied | Low | Request owner statements or booking-platform exports |
| Agent forecast | Assumed available | Medium | Ask for comparable-property basis |
| Comparable listings | Not yet validated | Low | Match beds, location, quality, amenities and reviews |
| Seasonality split | Broad assumption only | Low | Split peak, shoulder and low season |
| Cleaning fee treatment | Unclear | Low | Confirm whether cleaning is income, pass-through or owner cost |
| Local-use evidence | Not verified | Low | Check exact property position with qualified sources |
The table shows why the example should not move straight from forecast to offer. The model may still be worth exploring, but the evidence quality is not yet strong.
Building the cost model
Gross bookings are only the top line. The investor decision depends on the amount left after management fees, cleaning, platform costs, utilities, insurance, repairs, replacement reserve, safety/admin costs, local compliance items, contingency, setup costs and finance.
The base case below uses a full-service management route. Self-management could reduce direct fees, but may increase workload, response-time risk, supplier coordination and operational exposure.
Illustrative base-case annual cost table
| Line item | Illustrative assumption | Annual amount |
|---|---|---|
| Gross bookings, excluding cleaning fees | Base case | £38,000 |
| Management fee | 20% of gross bookings | £7,600 |
| Platform/payment/marketing costs | 3% of gross bookings | £1,140 |
| Cleaning and laundry owner exposure | Estimate | £3,500 |
| Utilities and broadband | Estimate | £3,000 |
| Insurance, safety and admin | Estimate | £1,400 |
| Maintenance and replacement reserve | Estimate | £3,500 |
| Compliance/admin placeholder | Estimate | £800 |
| Contingency | Estimate | £2,000 |
| Total operating costs before finance | £22,940 | |
| Net operating position before finance | £15,060 |
This is where the gross income trap becomes visible. A £38,000 booking forecast does not mean £38,000 of cashflow. In this illustrative model, operating costs before finance absorb about £22,940.

Finance assumptions and sensitivity
The next pressure point is finance. This article does not provide mortgage advice, recommend borrowing, or suggest any lender terms. The purpose is to show how a buyer can model finance sensitivity once they have their own confirmed assumptions.
In this example, the illustrative finance case is:
| Finance input | Illustrative assumption |
|---|---|
| Purchase price | £325,000 |
| Deposit | 25% |
| Deposit amount | £81,250 |
| Illustrative loan | £243,750 |
| Illustrative interest rate | 6.00% |
| Repayment route | Interest-only model for cashflow testing |
| Annual finance cost | £14,625 |
This simplified finance cost excludes arrangement fees, valuation fees, broker fees, repayment capital, tax effects and product-specific terms. Those items can be material. A buyer should not use this table as a borrowing plan. It is a stress-testing input.
After adding the illustrative annual finance cost, the base case becomes:
| Base-case cashflow step | Amount |
|---|---|
| Gross bookings | £38,000 |
| Total operating costs before finance | -£22,940 |
| Net operating position before finance | £15,060 |
| Illustrative finance cost | -£14,625 |
| Illustrative post-finance cashflow | £435 |
That £435 result is the main lesson. The property can appear to have a strong headline income, yet the post-finance position can be thin once realistic costs are included. The offer decision is sensitive.
Setup budget and launch costs
Setup spend is often underestimated because it does not appear in the annual income forecast. It can affect total capital deployed and the first-year return profile.
For this example, setup may include furniture, linen, kitchen equipment, photography, listing setup, safety checks, access systems, initial maintenance and working capital.
The illustrative setup budget is £30,000. Some properties may need less; a tired cottage, repositioning project, external works or compliance issue may require more. The cash required is not just the deposit.
Break-even occupancy
Break-even occupancy is one of the most useful checks because it converts a financial model into a booking-pressure question.
In this example, assume the average achieved nightly revenue is £175, excluding cleaning fees. At that rate, the £38,000 gross booking assumption implies about 217 booked nights:
| Metric | Illustrative calculation |
|---|---|
| Gross bookings | £38,000 |
| Average nightly revenue | £175 |
| Implied booked nights | 217 |
| Available nights | 365 |
| Implied occupancy | 59% |
The simplified break-even question is: how many booked nights are needed to cover operating costs and finance?
Using the base-case cost and finance assumptions:
| Break-even input | Amount |
|---|---|
| Operating costs before finance | £22,940 |
| Illustrative finance cost | £14,625 |
| Total cash cost to cover | £37,565 |
| Average nightly revenue | £175 |
| Approximate nights required | 215 |
| Approximate break-even occupancy | 59% |
This is a simplified estimate. Some costs vary with occupancy, some are fixed, and some may be recovered differently. Even so, it highlights the pressure.
If the property needs about 215 nights to break even and the base case assumes about 217 nights, there is little room for error. A small reduction in average rate, occupancy, availability or cost control may remove the surplus.
Downside case: what could break the deal
The downside case is where the model becomes useful. A serious buyer should not only ask whether the property works in a neat base case. They should ask what happens when the first version of the model is wrong.
For this example, we will stress four assumptions:
- Gross bookings fall from £38,000 to £32,000.
- Management rises from 20% to 22%.
- Maintenance, utilities and contingency are slightly higher.
- Illustrative finance cost rises from 6.00% to 7.00%.
Illustrative stress-case table
| Line item | Base case | Stress case |
|---|---|---|
| Gross bookings | £38,000 | £32,000 |
| Management fee | £7,600 | £7,040 |
| Platform/payment/marketing costs | £1,140 | £960 |
| Cleaning and laundry owner exposure | £3,500 | £3,500 |
| Utilities and broadband | £3,000 | £3,200 |
| Insurance, safety and admin | £1,400 | £1,500 |
| Maintenance and replacement reserve | £3,500 | £4,200 |
| Compliance/admin placeholder | £800 | £800 |
| Contingency | £2,000 | £2,500 |
| Operating costs before finance | £22,940 | £23,700 |
| Net operating position before finance | £15,060 | £8,300 |
| Illustrative finance cost | £14,625 | £17,063 |
| Illustrative post-finance cashflow | £435 | -£8,763 |
The stress case does not prove that the property is poor. It proves that the decision is sensitive to evidence. If the buyer cannot support the £38,000 income assumption, cannot control costs, or cannot secure the finance terms they modelled, the offer price may need to change.
This is also where the Investment Comparison Engine becomes useful. A buyer can compare this Cornwall property against:
- A lower-priced Cornwall property with weaker income but lower finance pressure
- A Devon property with different purchase price and management costs
- A Lake District property with different seasonality
- A Spain or Portugal opportunity with currency and local-rule risks
- A self-managed version of the same property
- An agency-managed version of the same property
The comparison may show that the property is still competitive, or that the buyer is accepting too much risk for too little margin.
Offer risk: target price, walk-away price and evidence gaps
An offer price should be an output of the model. It should not be based only on the asking price, the seller’s expectation, or a broad view that Cornwall is a strong holiday-let market.
For this example, there are three unresolved questions before a buyer could form a disciplined offer:
- Is the £38,000 gross booking assumption supported by property-specific evidence?
- Are the operating costs complete, especially management, cleaning, maintenance and reserve?
- Does the property still work after confirmed finance terms, setup spend and professional checks?
If the answer to any of those questions is weak, the buyer may need a lower offer price, a larger reserve, a different management route, or a decision to walk away.
Evidence-gap table before offer
| Assumption | Why it matters | Evidence needed | Offer-risk impact |
|---|---|---|---|
| Gross bookings | Drives the whole model | Actual bookings or strong comparables | High |
| Occupancy by season | Tests low-season resilience | Peak, shoulder and winter split | High |
| Average nightly revenue | Converts demand into cashflow | Comparable nightly rates by season | High |
| Management fee | Major cost line | Written fee schedule | Medium |
| Cleaning and laundry | Can erode margin | Local supplier quote or agency schedule | Medium |
| Maintenance reserve | Protects against optimism | Condition review and reserve policy | Medium |
| Setup budget | Increases cash required | Furniture and launch budget | Medium |
| Finance cost | Can decide cashflow | Broker/lender confirmation | High |
| Local use position | Can affect operation | Qualified property-specific checks | High |
The Deal Checker should be used at this stage because the question has changed. The buyer is no longer asking "What might this earn?" They are asking "Does the evidence support this specific deal?"
What to ask before making an offer
Before turning this model into an offer, the buyer should have written answers to these questions:
- What evidence supports the £38,000 gross booking assumption?
- Are the comparables genuinely similar in location, size, quality, parking, guest capacity and review strength?
- How much of the income is peak-season dependent?
- Are cleaning, laundry, platform fees and agency fees treated consistently?
- What setup spend is needed before the first booking season?
- What finance terms, fees and repayment assumptions have been confirmed externally?
- What property-specific local, lease, insurance or planning checks remain unresolved?
- What offer price still works if the stress case is closer to reality than the base case?
How to rebuild the analysis in Holiday Let Investor
The worked example maps directly into the Holiday Let Investor workflow.
1. Research
Start with the investment question: "Can a £325,000 Cornwall holiday let survive realistic income, cost, setup and finance assumptions?"
Research should include area demand, comparables, property type, guest profile, management options, local evidence and professional-check prompts. It should not be based on destination appeal alone.
2. Holiday Let Calculator
Use the Holiday Let Calculator to structure the first version of the model:
- Purchase price
- Income assumption
- Operating costs
- Setup costs
- Finance assumptions
- Management route
- Cashflow and break-even pressure
3. Deal Checker
Use the Deal Checker when a specific property looks serious. The Deal Checker should capture the property’s evidence gaps, risk notes and assumption quality.
For this example, the Deal Checker would flag unsupported income evidence, thin post-finance margin, finance sensitivity and the need to verify local-use assumptions.
4. Investment Comparison Engine
Use the Investment Comparison Engine before becoming committed to one property. Compare this Cornwall model against alternative properties, areas and management routes.
The key question is not whether this one deal can be made to look acceptable. It is whether it is the best risk-adjusted use of the buyer’s capital.
5. £39 Spreadsheet / Property Report
When the property deserves deeper work, export or build a decision record using the £39 holiday let investment spreadsheet and Property Report. This is where the assumptions, evidence, base case, stress case and offer logic should be documented.
A serious property needs a saved record because finance terms, surveys, repair budgets, local checks and agent evidence can all change the model.
6. Pro
Use Pro when a buyer is comparing repeated opportunities, saving criteria, tracking setup budgets, reviewing actuals, or managing a live buying process.
The value is keeping the decision record updated as new evidence arrives.
7. AI Investment Intelligence
Use AI Investment Intelligence as an evidence-review layer inside the workflow. It should help challenge assumptions, identify missing inputs, summarise risk notes and prepare follow-up questions.
AI should not be treated as a replacement for professional advice or buyer judgement. It is most useful when the inputs are structured, labelled and evidence-led.
FAQs
What return should a Cornwall holiday let make?
There is no single return that a Cornwall holiday let should make. The result depends on price, property type, evidenced income, operating costs, management route, setup spend, finance cost, tax position and property-specific checks. Model conservative and stress cases rather than relying on a headline forecast.
How do I verify a Cornwall holiday-let income forecast?
Ask what the forecast is based on. Stronger evidence includes actual booking history, closely matched comparables, seasonal occupancy splits, nightly-rate evidence and clear fee treatment. Unsupported estimates should be treated as assumptions, not proof.
What can make a Cornwall holiday-let deal fail?
A deal can fail because income is overstated, costs are incomplete, finance is more expensive than expected, setup spend is underestimated, low-season demand is weak, management costs are higher, or property-specific restrictions affect use.
Should I lower my offer if the forecast is not evidenced?
A weak forecast does not automatically tell you what to offer, but it should increase caution. The buyer may need stronger evidence, a wider contingency, a lower price, or a decision to walk away.
What should go into a holiday-let spreadsheet before an offer?
At minimum, include purchase price, deposit, finance assumptions, gross bookings, occupancy, average nightly rate, management, cleaning, utilities, insurance, maintenance, contingency, setup spend, break-even occupancy, stress cases and evidence notes.
Conclusion
The £325,000 Cornwall example is not a prediction. It is a method for deciding whether the evidence is strong enough to keep working on the deal.
The base case shows how a property with a plausible gross booking assumption can still produce a narrow post-finance margin. The stress case shows how quickly that margin can disappear when income is lower, costs are higher, or finance terms weaken.
That is why a buyer should move through the full Holiday Let Investor workflow:
