Nightly rate × occupancy, minus the real costs — get your monthly profit and the break-even occupancy you must hit. Works for rent-to-SA or owned. No sign-up.
PropertyPredator can use available short-let nightly rates and occupancy for your area and bedroom count. Coverage varies; review the market figures or enter your own assumptions. Compare the result with break-even before you sign a rent-to-SA contract.
The occupancy % at which the SA exactly covers its costs — below it you lose money, above it you profit. It's the single most important number in an SA deal: if break-even is 70% and the area only does 60%, walk away.
Yes — put your rent to the landlord in the "rent or mortgage" box. If you own it, put your mortgage payment there instead. Everything else is the same.
Revenue is nightly rate × occupancy × ~30 nights. A £10 swing in nightly rate, or 10% occupancy, completely changes the profit — which is why guessing them is dangerous. Use real local data.
