Holiday Let or Buy-to-Let in Cornwall: What the Numbers Show
Verdict: Holiday let wins on gross revenue, generating roughly 147% more than buy-to-let, but only above a real occupancy threshold.
Best For: Hands-on operators who can sustain coastal-season occupancy; buy-to-let suits passive investors prepared to accept thin net margins.

Underlying Assumptions (data as of October 2026):
- Property Price: 3-bedroom houses estimated at around £293,000
- Monthly Long-Term Rent: Approximately £1,100
- Holiday Let Nightly Rate: Around £200 per night (varies seasonally)
- Assumed Holiday Let Occupancy: 47% average across the region (varies significantly between specific locations)
- Available Holiday Let Nights: 330 per year (assumes roughly 35 days for cleaning, changeovers, and maintenance)
- Regulations: Permissive. No night cap (the 90-day rule applies only within Greater London). Change-of-use planning consent may be required for full-time holiday lets, and many councils now operate selective licensing.

Estimates for a typical 3-bedroom house. Figures are modelled from market data; not guaranteed outcomes.
Both revenue figures match the Dashboard's calculation for this market.
Holiday let grosses around 147% more than buy-to-let in Cornwall, but operating costs (cleaning, platform fees, utilities, council tax during voids) eat a much larger share of holiday let revenue than they do for buy-to-let.
Holiday Let Gross Revenue Matches Buy-to-Let at 19% Occupancy
Cornwall's gross break-even threshold sits high: holiday let gross revenue matches buy-to-let annual rent at roughly 19% occupancy. After-costs break-even is higher because holiday lets carry larger operating overheads. The Cornwall regional average sits at 47%, which gives the strategy real headroom, but coastal markets are profoundly seasonal and individual properties can land well below the regional figure outside school holidays.
Occupancy sensitivity matters because buy-to-let income is essentially fixed once tenanted, while holiday let income swings with bookings. At a softer 32% occupancy, holiday let gross revenue falls to roughly £21,000; at a stronger 57%, it rises to about £38,000. The 100% theoretical ceiling is £66,000 for the 330 available nights.
Cornwall Suburb Yields Range Widely Across the Postcode Map
Cornwall is not a single market. The buy-to-let yield gap between the highest- and lowest-yielding postcode areas is wide, and holiday let economics shift even more dramatically with proximity to coast and tourist nodes. The dashboard ranks 45 postcode areas across Cornwall and the wider South West.
Top buy-to-let yields by postcode area (3-bedroom house, modelled).
The ranking flips entirely for holiday let. Inland market towns like Launceston (PL15) and Liskeard (PL14) carry the strongest buy-to-let yields because sale prices stay close to the regional median while rents track local wages. Coastal postcodes (St Ives, Padstow, Rock, Polzeath, Falmouth) command far higher nightly rates and stronger summer occupancy but trade at much higher per-square-foot prices, so their buy-to-let yields lag.

Operating Costs Take a Bigger Bite from Cornwall Holiday Lets
The headline Cornwall holiday let gross yield of 10.6% compresses to a net yield of approximately 5.9% once running costs are taken out. Buy-to-let starts lower at 4.3% gross and lands at roughly 2.3% net. The gap narrows but holiday let still wins on net cash flow at the regional average occupancy.
For a typical 3-bedroom Cornwall house held as a holiday let, annual operating costs total around £14,000, leaving net income near £17,000. The line items: Airbnb host-only fees of 15.5% on bookings (about £4,800 per year), specialist holiday let insurance of about £1,400, maintenance and furnishing replacement of about £5,200 (higher than buy-to-let because of guest turnover and wear), utilities of about £2,300 that the host pays. Council tax is replaced by business rates for holiday lets, often reducing that line to £0 with Small Business Rate Relief relief; see methodology below. Note that other booking channels charge differently: Vrbo around 8%, Booking.com around 15%, and direct bookings carry no platform fee.
Buy-to-let costs are far simpler. Total annual operating costs are roughly £5,800, leaving net income near £6,700. The main lines are letting agent fees of around 11% of rent collected, landlord insurance of about £570, and maintenance of about £3,500. Council tax is typically the tenant's responsibility while tenanted, though the landlord pays during voids.
Holiday let management is excluded from the figures above because most Cornwall investors self-manage, lean on a local cleaner, and use a property manager only as a contingency. If you choose to hire a professional manager instead of self-managing, add roughly £6,800 per year, which would compress the net yield significantly. Cornwall's higher-end coastal lets often run at agency commissions of around 22%, the regional norm.
Cornwall Council Tax and Business Rates Have Tightened
Cornwall Council applies a 100% council tax premium on second homes from April 2025, doubling the bill for properties not occupied as a main residence. Holiday lets that meet the letting threshold (currently 70 nights actually let plus 140 nights available) can shift to business rates instead of council tax, and many smaller properties qualify for Small Business Rate Relief, reducing the bill to nil. Properties failing the threshold default back to council tax, now at the doubled rate. This is one of the most impactful local rules in the UK and should be checked against the most recent council guidance before purchase.
Tax Implications for Cornwall Investors
The Furnished Holiday Lettings (FHL) tax regime was abolished from April 2025. Cornwall holiday lets and buy-to-let properties are now taxed equivalently. Profits are charged to income tax at your marginal rate, mortgage interest is restricted to a 20% basic-rate tax credit (no longer fully deductible), and the previous capital gains and pension advantages of FHL status no longer apply.
Stamp duty is a material cost on a Cornwall purchase. The 5% surcharge on additional properties applies on top of the standard banded rates for any second-home or buy-to-let purchase in England. Calculate the actual amount with your solicitor or conveyancer because rates and bands change. On a £293,000 property, the surcharge alone is a sizeable capital outlay before the standard banded rates are added.
Capital gains tax on residential property runs at 18% basic rate or 24% higher rate (from October 2024). Allowable expenses against rental income include repairs, insurance, letting agent fees, and ground rent for leasehold properties. Holiday let operators retain access to the trading-style expense rules for genuinely furnished, available-for-letting properties even after FHL abolition, but the headline tax advantage that historically made coastal holiday lets attractive is gone.
Cornwall Yields Sit Below the National Average but Track the South West
Cornwall's buy-to-let gross yield of 4.3% sits just below the South West regional average of 4.6% and well below the UK national median of 5.5%. Sale prices (about £293,000) run above the UK median (about £261,000) while rents (about £1,100) sit only marginally below the UK figure (about £1,200), which is why the yield lags.
Comparison of key investment metrics.
| Metric | Cornwall | South West Avg | UK Average |
|---|---|---|---|
| 3-Bed Sale Price | £293,000 | £301,000 | £261,000 |
| Monthly Rent | £1,100/mo | £1,200/mo | £1,200/mo |
| Gross Yield (Buy-to-Let) | 4.3% | 4.6% | 5.5% |
The Cornwall premium is paid in capital values, not rents. For pure yield-chasing investors, regional cities further north typically deliver stronger headline numbers; for blended income-and-amenity investors, Cornwall's holiday let optionality and capital appreciation history justify the lower buy-to-let yield.
Investment Bottom Line
Cornwall is fundamentally a holiday let market for investors who can execute. The 147% gross revenue premium over buy-to-let, even after the more demanding cost base, leaves holiday let with the higher net cash flow at the regional average occupancy. But the strategy is operationally intensive, FHL abolition has removed a long-standing tax tailwind and the new council tax premium adds a fresh headwind, and while gross break-even of around 19% is comfortably below the regional average, individual inland properties can still struggle to clear net costs outside peak season.
Buy-to-let in Cornwall offers stable but modest cash flow, with net yields around 2.3% once costs are accounted for. It suits investors prioritising appreciation exposure and minimal day-to-day involvement.
| Investor Type | Fit |
|---|---|
| Cash Flow Focused | Good (holiday let only) |
| Appreciation Focused | Excellent |
| Holiday Let Operator | Excellent |
| High Leverage (80%+ LTV) | Fair |

Methodology and Assumptions
Defaults used in the figures above. All inputs are adjustable in the dashboard.
How available nights are determined
Available nights default to 330 per year, reflecting an active operator with minimal blocked time. Where local regulations cap whole-home short-term lets (for example London at 90 nights and Edinburgh under the city-wide control area), the cap is applied. In markets where short-term rental requires owner-occupancy or is otherwise prohibited for investment properties, available nights drop to zero.
How occupancy is measured
The percentage of available nights that get booked, drawn from market data. A property listed for 200 nights with 100 bookings shows 50% occupancy. Adjustable in the dashboard.
Long-term rental management default
Includes a 11% letting agent fee, the standard arrangement for UK buy-to-let investors who use a managing agent. Self-managed landlords can adjust this to zero in the dashboard.
Short-term rental management default
Set to self-managed (zero management fee) by default, the most common arrangement for individual investors. Hiring a professional manager typically costs around 22% of gross revenue and reduces net yield proportionally. Toggle in the dashboard.
How property tax is calculated
Council tax in the UK is typically paid by the tenant for long-term rentals, so it is excluded from buy-to-let costs. Holiday lets are usually assessed as business rates and may qualify for Small Business Rate Relief, often reducing this to zero.
Local regulations
Check local council and freeholder or management company rules before investing; these change frequently. The regulations summary in this article reflects the latest data we hold. Always verify the live position with the local council.
Sampling and data sources
Short-term rental yield figures reflect properties currently listed on short-term rental platforms. In high-tourism markets, listings tend to concentrate in central postcodes, which can pull city-median yields above what residential areas of the same city would achieve. Yields for any specific suburb may differ significantly from the city-wide median.
