In the UK, it is still popular for homeowners to rent out spare rooms in their homes. As a resident landlord, you are responsible for maintaining the entire property and keeping it in good condition. You can earn up to £4,250 per year tax-free from renting a room. There are two types of lodgers - excluded occupiers share common spaces and can be asked to leave with notice, while separate lodgers require an eviction through courts if they do not pay rent. The tenancy agreement should outline the rent amount, names, addresses, and letting period, which can be monthly or for a fixed term.
