Holiday Let vs Buy-to-Let: How to Compare the Numbers

Revenue stability

Buy-to-let rent is usually agreed monthly for a tenancy period. It can still be interrupted by voids, arrears or repairs, but the revenue pattern is relatively predictable. Holiday-let revenue is more variable. Peak weeks may carry the year, while winter periods may be quiet or require discounting.

When comparing the two, avoid using the best holiday-let month as the annual average. Split the holiday-let year into seasons and include realistic booked weeks. Then compare annual gross income with a buy-to-let rent assumption that includes a sensible void allowance.

Operating costs

A buy-to-let tenant often pays utilities and council tax, while the landlord handles maintenance, insurance, compliance and letting costs. In a holiday let, the owner commonly pays utilities, broadband, cleaning, linen, platform fees, management, guest consumables and more frequent replacements.

This is why net yield before mortgage matters. It compares the property result after operating costs but before finance. If the holiday let has a much higher gross yield but only a slightly higher net yield, the extra complexity may not be worth it unless you value the lifestyle use or growth potential.

Finance and cash invested

Holiday-let mortgages can have different criteria from standard buy-to-let mortgages. Lenders may assess projected holiday-let income, personal income, location, property type and management approach. Rates, fees and deposit requirements can differ, so do not assume the finance will match a buy-to-let product.

Cash invested also differs. A holiday let may need a larger furnishing and setup budget, professional photography and launch costs. Compare cash-on-cash return after including deposit, stamp duty, legal costs and setup costs. Ignoring setup spend can make the holiday-let case look artificially strong.

Workload and management

A self-managed holiday let can become an active hospitality business. Guest messages, pricing, changeovers, damage, supplies, reviews and urgent fixes all need systems. Agency management can reduce workload but takes a percentage of revenue and may still require owner decisions.

A buy-to-let is not passive, but the rhythm is different. If you are comparing strategies for investment rather than lifestyle, give your time a value. A holiday let with slightly higher cashflow may not be better if it creates a workload you do not want.

Risk and regulation

Holiday-let performance can be affected by local competition, tourism demand, mortgage rates, planning rules, licensing, tax changes and platform policies. Buy-to-let faces its own regulatory and tax risks, but the operational exposure is different. Neither is automatically safer.

Use scenarios. For the holiday let, reduce booked weeks and rates while increasing costs. For the buy-to-let, include voids, repairs and rate changes. The strategy that survives a realistic downside with less stress may be more suitable than the one with the highest base-case return.

Before you rely on the scenario

Treat the numbers as a decision screen, not a decision in themselves. A useful holiday-let model should help you decide what to research next: which costs need quotes, which revenue assumptions need evidence, which finance terms need broker confirmation and which legal points need a solicitor. The output is strongest when each assumption has a source, even if that source is only an agent estimate, comparable listing review or supplier quote at the early stage.

Keep a simple evidence file for the property. Save comparable listings, agent income estimates, cleaner quotes, management fee schedules, insurance indications, service charge details, utility assumptions, mortgage illustrations and notes from calls. When the calculator shows a strong result, the evidence file helps you test whether that strength is real. When it shows a weak result, it helps you see which assumption would need to change before the property is worth more time.

Finally, run at least three versions of the deal. The base case should reflect your honest current view. The downside case should reduce revenue and increase costs enough to feel uncomfortable but plausible. The upside case can show what happens if the property performs well, but it should not be the only case used to justify an offer. A deal that survives a cautious downside is usually easier to own than one that needs every assumption to land perfectly.

If the scenario changes materially after one quote, one fee schedule or one mortgage rate update, that is useful information. It means the margin of safety is thin and the purchase needs more evidence before you spend money on surveys or legal work. The best early analysis makes uncertainty visible while there is still time to negotiate, pause or compare another property.

Use the guide with your own numbers

The next step is to turn the assumptions into a scenario for the actual property you are considering. Start with the free holiday-let calculator, compare the model in the premium spreadsheet, or request a practical property review if you want a structured second look.
