Yes, it is possible to build an Airbnb-style business with little or no upfront capital in the UK. Options include rental arbitrage (subletting a rented property with landlord consent), co-hosting for existing Airbnb hosts, managing properties on behalf of owners for a percentage fee, or offering Airbnb Experiences. Each model has different income potential and risk levels. Lower-capital routes typically require more negotiation skill and operational effort rather than property ownership.
