The Hidden Costs of Running an Airbnb That Nobody Talks About
Most hosts know what their property earns. Far fewer know what it actually costs to run. A forensic breakdown of the real costs that erode STR margins.
The short-term rental industry has a revenue problem. Not a revenue generation problem — most STR properties in desirable destinations generate meaningful gross revenue. The problem is the gap between gross revenue and net profit, and specifically the systematic underestimation of the costs that fill that gap.
Platform Fees — The First and Most Visible Cost
Airbnb charges hosts a service fee on every booking. Under the split-fee model, the host pays approximately 3% of the booking subtotal per transaction. Under the host-only fee model, the fee is typically 14% to 16% of the booking subtotal. A host listing at £150 per night under the host-only fee model is receiving approximately £127 per night after Airbnb's fee — before any other costs are deducted.
Cleaning Costs — The Most Frequently Underestimated Operational Cost
Cleaning is the largest recurring operational cost for most STR properties. For a two-bedroom Lake District property turning over on a Saturday schedule throughout the peak season, the annual cleaning cost at professional rates can easily reach £3,000 to £5,000.
Carl McGlasson: One of the most common errors I see in STR financial modelling is hosts who have budgeted a cleaning fee that covers a basic domestic clean and then discovered that a proper STR turnover — to the standard that actually protects their review score — costs significantly more.
Linen and Laundry — The Cost That Creeps Up
A properly stocked two-bedroom STR property requires a minimum of two complete linen sets per bed, plus three to four towel sets per bathroom. At quality hospitality-grade levels, this represents an initial investment of £1,500 to £3,000. A realistic linen replacement budget for an actively occupied STR property is £300 to £600 per year.
Maintenance — The Cost That Spikes
Maintenance costs for STR properties are structurally higher than for equivalent long-term rental properties. A realistic maintenance budget is 1% to 2% of the property's value per year, often higher in practice for high-occupancy STR properties.
Insurance — The Cost Many Hosts Are Getting Wrong
Standard home insurance does not cover short-term rental activity. Specialist STR insurance typically costs between £400 and £1,200 per year depending on property value and coverage level. This is non-negotiable for a responsibly operated STR property.
Tax — The Changed Landscape of 2025
The furnished holiday let tax regime that provided significant tax advantages to STR operators was abolished from April 2025. STR income is now taxed under the same rules as other property rental income, with the loss of the specific FHL advantages that made the STR financial model particularly attractive to higher-rate taxpayers.
The True Profit Calculation
Against a gross annual revenue of £30,000 for a well-occupied Lake District two-bedroom property, total operating costs realistically range from £11,500 to £18,000. Net operating profit, before tax and before mortgage costs, is in the range of £12,000 to £18,500.
STR revenue is what your property earns. STR profit is what you keep. Most hosts know the first number. Fewer know the second. The hosts who build durable, profitable STR operations are almost always the ones who understand their numbers in full.
